This is an \u003cstrong\u003eSL (Super Light)\u003c\/strong\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 \u003cstrong\u003e256g\u003c\/strong\u003e. Step down a tier to \u003cstrong\u003eEL\u003c\/strong\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\u003eShimano vs SRAM: What Actually Differs\u003c\/h3\u003e\n\u003cp\u003eShimano and SRAM chains of the same speed count share the same nominal chain pitch, but the two brands tune inner link width, pin length, and outer-plate chamfering differently to match their own derailleur cage geometry, cassette tooth-ramp profile, and quick-link design — Shimano's own quick-link versus SRAM's PowerLock\/Flattop link.

Combined with a 4-micron anti-corrosion coating tested through 1000+ hours of salt spray, the S12 PRO is built to run clean and quiet well past where an ordinary chain would need relubing.\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;\"\u003eSRAM 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;\"\u003eSilver\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-SRAM-S12SL-PRO-SV\u003c\/p\u003e","brand":"SUMC","offers":[{"title":"Default Title","offer_id":67571028558128,"sku":"SMC-SRAM-S12SL-PRO-SV","price":3600.0,"currency_code":"INR","in_stock":false}],"url":"https:\/\/www.dogoodco.in\/products\/sumc-s12-pro-chain-12-speed-sram-silver","provider":"DoGoodCo","version":"1.0","type":"link"}
