SUMC set out to give Shimano riders more options, engineering a flat-top chain built specifically to run on Shimano systems too. The result is a chain shape that was previously off-limits to Shimano users, now available to them for the first time.\u003c\/p\u003e\n\u003ch3\u003eShimano vs SRAM: What Actually Differs\u003c\/h3\u003e\n\u003cp\u003eShimano and SRAM both use the same nominal chain pitch at 12-speed, but each brand tunes inner link width, pin length, and outer-plate chamfering differently to match its own derailleur cage geometry, cassette tooth-ramp profile, and quick-link\/master-link design. This S12SL PRO chain is engineered and tuned specifically to Shimano's spec; SUMC also produces a separate SRAM-tuned version of this same tier for SRAM drivetrains.

Step down a tier to \u003cb\u003eEL\u003c\/b\u003e and the pins become solid while the side plates keep their cut-outs, landing at 268.5g. Chains with no suffix at all use solid pins and solid side plates throughout — the sturdiest and heaviest of the three, at 274.3g.

SUMC set out to give Shimano riders more options, engineering a flat-top chain built specifically to run on Shimano systems too. The result is a chain shape that was previously off-limits to Shimano users, now available to them for the first time.\u003c\/p\u003e\n\u003ch3\u003eShimano vs SRAM: What Actually Differs\u003c\/h3\u003e\n\u003cp\u003eShimano and SRAM both use the same nominal chain pitch at 12-speed, but each brand tunes inner link width, pin length, and outer-plate chamfering differently to match its own derailleur cage geometry, cassette tooth-ramp profile, and quick-link\/master-link design. This S12SL PRO chain is engineered and tuned specifically to Shimano's spec; SUMC also produces a separate SRAM-tuned version of this same tier for SRAM drivetrains. This listing is the Shimano-tuned version.\u003c\/p\u003e\n\u003ch3\u003eSL, EL, or No Suffix: What the Name Tells You\u003c\/h3\u003e\n\u003cp\u003eSUMC's tier naming isn't just marketing — it describes exactly how the chain is machined. This is an \u003cb\u003eSL (Super Light)\u003c\/b\u003e chain: it has hollow pins AND cut-out side plates, the lightest construction SUMC builds, bringing this 12-speed flat-top chain down to just \u003cb\u003e256g\u003c\/b\u003e. Step down a tier to \u003cb\u003eEL\u003c\/b\u003e and the pins become solid while the side plates keep their cut-outs, landing at 268.5g. Chains with no suffix at all use solid pins and solid side plates throughout — the sturdiest and heaviest of the three, at 274.3g. As more material is machined away, weight drops and price rises, so you can pick the tier that matches how much you're willing to spend to save grams.\u003c\/p\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;margin:20px 0;\"\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eTier\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003ePins\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eSide Plates\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eWeight\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eSL\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eHollow\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eCut-out\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e256g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eEL\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eSolid\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eCut-out\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e268.5g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eNo suffix\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eSolid\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eSolid\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e274.3g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhy SUMC?\u003c\/h3\u003e\n\u003cp\u003eSUMC is the only manufacturer in the world producing a Shimano-compatible flat-top chain, a design otherwise exclusive to SRAM's own Flattop standard.

SUMC set out to give Shimano riders more options, engineering a flat-top chain built specifically to run on Shimano systems too. The result is a chain shape that was previously off-limits to Shimano users, now available to them for the first time.\u003c\/p\u003e\n\u003ch3\u003eShimano vs SRAM: What Actually Differs\u003c\/h3\u003e\n\u003cp\u003eShimano and SRAM both use the same nominal chain pitch at 12-speed, but each brand tunes inner link width, pin length, and outer-plate chamfering differently to match its own derailleur cage geometry, cassette tooth-ramp profile, and quick-link\/master-link design. This S12SL PRO chain is engineered and tuned specifically to Shimano's spec; SUMC also produces a separate SRAM-tuned version of this same tier for SRAM drivetrains.

This is an \u003cb\u003eSL (Super Light)\u003c\/b\u003e chain: it has hollow pins AND cut-out side plates, the lightest construction SUMC builds, bringing this 12-speed flat-top chain down to just \u003cb\u003e256g\u003c\/b\u003e. Step down a tier to \u003cb\u003eEL\u003c\/b\u003e and the pins become solid while the side plates keep their cut-outs, landing at 268.5g. Chains with no suffix at all use solid pins and solid side plates throughout — the sturdiest and heaviest of the three, at 274.3g.

Step up to the \u003cb\u003eEL\u003c\/b\u003e tier and the side plates gain cut-outs, dropping weight to 268.5g. Step up again to the \u003cb\u003eSL (Super Light)\u003c\/b\u003e tier and the pins become hollow too, for the lightest build at 256g.

SUMC set out to give Shimano riders more options, engineering a flat-top chain built specifically to run on Shimano systems too. The result is a chain shape that was previously off-limits to Shimano users, now available to them for the first time.\u003c\/p\u003e\n\u003ch3\u003eShimano vs SRAM: What Actually Differs\u003c\/h3\u003e\n\u003cp\u003eShimano and SRAM both use the same nominal chain pitch at 12-speed, but each brand tunes inner link width, pin length, and outer-plate chamfering differently to match its own derailleur cage geometry, cassette tooth-ramp profile, and quick-link\/master-link design. This S12SL PRO chain is engineered and tuned specifically to Shimano's spec; SUMC also produces a separate SRAM-tuned version of this same tier for SRAM drivetrains. This listing is the Shimano-tuned version.\u003c\/p\u003e\n\u003ch3\u003eSL, EL, or No Suffix: What the Name Tells You\u003c\/h3\u003e\n\u003cp\u003eSUMC's tier naming isn't just marketing — it describes exactly how the chain is machined. This is an \u003cb\u003eSL (Super Light)\u003c\/b\u003e chain: it has hollow pins AND cut-out side plates, the lightest construction SUMC builds, bringing this 12-speed flat-top chain down to just \u003cb\u003e256g\u003c\/b\u003e. Step down a tier to \u003cb\u003eEL\u003c\/b\u003e and the pins become solid while the side plates keep their cut-outs, landing at 268.5g. Chains with no suffix at all use solid pins and solid side plates throughout — the sturdiest and heaviest of the three, at 274.3g. As more material is machined away, weight drops and price rises, so you can pick the tier that matches how much you're willing to spend to save grams.\u003c\/p\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;margin:20px 0;\"\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eTier\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003ePins\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eSide Plates\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eWeight\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eSL\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eHollow\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eCut-out\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e256g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eEL\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eSolid\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eCut-out\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e268.5g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eNo suffix\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eSolid\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eSolid\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e274.3g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhy SUMC?\u003c\/h3\u003e\n\u003cp\u003eSUMC is the only manufacturer in the world producing a Shimano-compatible flat-top chain, a design otherwise exclusive to SRAM's own Flattop standard.

SUMC set out to give Shimano riders more options, engineering a flat-top chain built specifically to run on Shimano systems too. The result is a chain shape that was previously off-limits to Shimano users, now available to them for the first time.\u003c\/p\u003e\n\u003ch3\u003eShimano vs SRAM: What Actually Differs\u003c\/h3\u003e\n\u003cp\u003eShimano and SRAM both use the same nominal chain pitch at 12-speed, but each brand tunes inner link width, pin length, and outer-plate chamfering differently to match its own derailleur cage geometry, cassette tooth-ramp profile, and quick-link\/master-link design. This S12SL PRO chain is engineered and tuned specifically to Shimano's spec; SUMC also produces a separate SRAM-tuned version of this same tier for SRAM drivetrains. This listing is the Shimano-tuned version.\u003c\/p\u003e\n\u003ch3\u003eSL, EL, or No Suffix: What the Name Tells You\u003c\/h3\u003e\n\u003cp\u003eSUMC's tier naming isn't just marketing — it describes exactly how the chain is machined. This is an \u003cb\u003eSL (Super Light)\u003c\/b\u003e chain: it has hollow pins AND cut-out side plates, the lightest construction SUMC builds, bringing this 12-speed flat-top chain down to just \u003cb\u003e256g\u003c\/b\u003e. Step down a tier to \u003cb\u003eEL\u003c\/b\u003e and the pins become solid while the side plates keep their cut-outs, landing at 268.5g. Chains with no suffix at all use solid pins and solid side plates throughout — the sturdiest and heaviest of the three, at 274.3g. As more material is machined away, weight drops and price rises, so you can pick the tier that matches how much you're willing to spend to save grams.\u003c\/p\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;margin:20px 0;\"\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eTier\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003ePins\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eSide Plates\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eWeight\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eSL\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eHollow\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eCut-out\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e256g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eEL\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eSolid\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eCut-out\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e268.5g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eNo suffix\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eSolid\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eSolid\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e274.3g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhy SUMC?\u003c\/h3\u003e\n\u003cp\u003eSUMC is the only manufacturer in the world producing a Shimano-compatible flat-top chain, a design otherwise exclusive to SRAM's own Flattop standard.

This Rainbow finish is one of 10 colorways in the S12SL PRO line — SUMC's widest color range at this tier.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;margin:20px 0;\"\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eSpeed\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e12-Speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eCompatibility\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eShimano 12-speed drivetrains\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eLink Design\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eFlat-top (crescent) outer plate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eChain Pitch\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e1\/2\" x 11\/128\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eFinish\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eRainbow\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eLinks\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e126\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp style=\"font-size:12px;color:#9a9a9a;border-top:1px solid #e5e5e5;padding-top:10px;\"\u003eSKU: SMC-S12SL-PRO-RNBW\u003c\/p\u003e","brand":"SUMC","offers":[{"title":"Default Title","offer_id":67571030229296,"sku":"SMC-S12SL-PRO-RNBW","price":7900.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0862\/7585\/0544\/files\/S12SL_Pro_Rnbw.png?v=1787662454"},{"product_id":"sumc-flat-top-quick-link-12-speed-shimano-black","title":"SUMC Flat Top Quick Link 12 Speed Shimano Black","description":"\u003cp style=\"text-transform:uppercase;letter-spacing:2px;font-size:12px;color:#8a8a8a;font-weight:700;\"\u003eSUMC · FLAT TOP QUICK LINK · SHIMANO\u003c\/p\u003e\n\u003ch2\u003eFlat Top Quick Link — Black\u003c\/h2\u003e\n\u003cp\u003eA 12-speed flat-top quick link finished in black, built to match SUMC's flat-top (crescent) chain platform for a clean, secure connection on Shimano 12-speed drivetrains.\u003c\/p\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;margin:20px 0;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:50%;border:1px solid #e5e5e5;padding:16px;vertical-align:top;\"\u003e\n\u003cdiv style=\"font-size:20px;\"\u003e😈\u003c\/div\u003e\n\u003cb\u003eFlat-Top Compatible\u003c\/b\u003e\u003cp style=\"color:#8a8a8a;font-size:13px;margin:4px 0 0;\"\u003eMatches SUMC's flat-top (crescent) chain platform — the only Shimano-compatible flat-top system on the market.\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width:50%;border:1px solid #e5e5e5;padding:16px;vertical-align:top;\"\u003e\n\u003cdiv style=\"font-size:20px;\"\u003e🛡️\u003c\/div\u003e\n\u003cb\u003eRust-Resistant Finish\u003c\/b\u003e\u003cp style=\"color:#8a8a8a;font-size:13px;margin:4px 0 0;\"\u003e4-micron anti-corrosion coating, salt-spray tested to 1000+ hours.\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eShimano vs SRAM: What Actually Differs\u003c\/h3\u003e\n\u003cp\u003eShimano and SRAM quick-links aren't interchangeable: each brand uses its own link mechanism (Shimano's quick-link vs SRAM's PowerLock\/Flattop link), and the two systems also differ in inner link width and pin length.

SUMC set out to give Shimano riders more options, engineering a flat-top chain built specifically to run on Shimano systems too. The result is a chain shape that was previously off-limits to Shimano users, now available to them for the first time.\u003c\/p\u003e\n\u003ch3\u003eShimano vs SRAM: What Actually Differs\u003c\/h3\u003e\n\u003cp\u003eShimano and SRAM both use the same nominal chain pitch at 12-speed, but each brand tunes inner link width, pin length, and outer-plate chamfering differently to match its own derailleur cage geometry, cassette tooth-ramp profile, and quick-link\/master-link design. This S12SL PRO chain is engineered and tuned specifically to Shimano's spec; SUMC also produces a separate SRAM-tuned version of this same tier for SRAM drivetrains.

This is an \u003cb\u003eSL (Super Light)\u003c\/b\u003e chain: it has hollow pins AND cut-out side plates, the lightest construction SUMC builds, bringing this 12-speed flat-top chain down to just \u003cb\u003e256g\u003c\/b\u003e.

SUMC set out to give Shimano riders more options, engineering a flat-top chain built specifically to run on Shimano systems too. The result is a chain shape that was previously off-limits to Shimano users, now available to them for the first time.\u003c\/p\u003e\n\u003ch3\u003eShimano vs SRAM: What Actually Differs\u003c\/h3\u003e\n\u003cp\u003eBoth Shimano and SRAM chains use the same nominal chain pitch at a given speed count, but each brand tunes inner link width, pin length, and outer-plate chamfering differently to match its own derailleur cage geometry, cassette tooth-ramp profile, and quick-link\/master-link design — Shimano's own quick-link is built differently from SRAM's PowerLock\/Flattop link. This entire SLPRO family is explicitly Shimano-tuned, not Sram: this chain is built to shift cleanly on Shimano derailleurs and cassettes. SUMC also produces a separate SRAM-tuned version of this chain at the same tier.\u003c\/p\u003e\n\u003ch3\u003eWhy SUMC?\u003c\/h3\u003e\n\u003cp\u003eSUMC is the only manufacturer in the world producing a Shimano-compatible flat-top chain — a link-plate design otherwise exclusive to SRAM's own Flattop standard. Every pin is sealed with a rubber O-ring that traps lubricant inside the roller and bushing, lubricating from the inside out and rated by SUMC for up to 10,000 km of riding. Inner\/outer plates and pin shafts are hollow-machined to a claimed 1-micron precision tolerance for less weight and faster dirt\/sediment discharge, with pins hardened to 1600+ HV and finished with double-nitriding plus a titanium-nitride coating. The Black Diamond finish carries a 4-micron anti-corrosion coating, salt-spray tested to 1000+ hours, and is RoHS\/REACH\/CPSIA compliant.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;margin:20px 0;\"\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eSpeed\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e12-Speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eCompatibility\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eShimano 12-speed drivetrains\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eLink Design\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eFlat-top (crescent) outer plate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eChain Pitch\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e1\/2\" x 11\/128\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eFinish\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003eBlack Diamond\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e\u003cb\u003eLinks\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:10px 14px;\"\u003e126\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp style=\"font-size:12px;color:#9a9a9a;border-top:1px solid #e5e5e5;padding-top:10px;\"\u003eSKU: SMC-SX12SLPRO-BKDM\u003c\/p\u003e","brand":"SUMC","offers":[{"title":"Default Title","offer_id":67571224838448,"sku":"SMC-SX12SLPRO-BKDM","price":5600.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0862\/7585\/0544\/files\/0066-78200557555791868.png?v=1787378656"},{"product_id":"sumc-sx11sl-chain-11-speed-gold-venom","title":"SUMC SX11SL Chain 11 Speed Gold Venom","description":"\u003cp style=\"text-transform:uppercase;letter-spacing:2px;font-size:12px;color:#8a8a8a;font-weight:700;\"\u003eSUMC · 11-SPEED SUPER LIGHT CHAIN\u003c\/p\u003e\n\u003ch2\u003eSX11SL Gold Venom\u003c\/h2\u003e\n\u003cp\u003eA striking Gold Venom finish on SUMC's hollow-machined 11-speed super light chain.\u003c\/p\u003e\n\u003cdiv style=\"background:#f4f4f4;border-radius:10px;padding:20px 24px;text-align:center;margin:20px 0;\"\u003e\n\u003cdiv style=\"font-size:32px;font-weight:800;\"\u003e10,000 KM\u003c\/div\u003e\n\u003cdiv style=\"text-transform:uppercase;letter-spacing:1px;font-size:12px;color:#8a8a8a;\"\u003eRated Riding Distance, Oil-Sealed Pins\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;margin:20px 0;\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"width:50%;border:1px solid #e5e5e5;padding:16px;vertical-align:top;\"\u003e\n\u003cdiv style=\"font-size:20px;\"\u003e⚖️\u003c\/div\u003e\n\u003cb\u003eHollow-Machined Ultra Light\u003c\/b\u003e\u003cp style=\"color:#8a8a8a;font-size:13px;margin:4px 0 0;\"\u003ePlates and pin shafts hollow-machined to 1-micron precision; pins hardened to 1600+HV with double-nitriding and titanium-nitride coating for durability.\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd style=\"width:50%;border:1px solid #e5e5e5;padding:16px;vertical-align:top;\"\u003e\n\u003cdiv style=\"font-size:20px;\"\u003e💧\u003c\/div\u003e\n\u003cb\u003eOil-Sealed Pins\u003c\/b\u003e\u003cp style=\"color:#8a8a8a;font-size:13px;margin:4px 0 0;\"\u003ePatented O-ring seals keep lubricant inside every roller, rated for up to 10,000km of riding.\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWhat \"SL\" Means in the Name\u003c\/h3\u003e\n\u003cp\u003eSUMC's tier naming describes exactly how a chain is machined.
