This is an \u003cstrong\u003eEL\u003c\/strong\u003e chain: the side plates have cut-outs like the SL tier, but the pins are solid (not hollow), landing this 12-speed flat-top chain at \u003cstrong\u003e268.5g\u003c\/strong\u003e. Step up to the \u003cstrong\u003eSL (Super Light)\u003c\/strong\u003e tier and the pins become hollow too, dropping weight to 256g. 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\u003ctbody\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;\"\u003eSL\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;\"\u003e\u003cb\u003eEL\u003c\/b\u003e\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\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eShimano vs SRAM: What Actually Differs\u003c\/h3\u003e\n\u003cp\u003eShimano and SRAM 12-speed drivetrains share the same nominal chain pitch, 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 master-link design — Shimano's own quick-link versus SRAM's PowerLock\/Flattop link. This S12EL PRO chain is built and tuned specifically for Shimano 12-speed drivetrains; 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's flat-top Shimano-compatible chain isn't available from any other manufacturer — flat-top link plates are otherwise exclusive to SRAM's own Flattop standard. Every pin is oil-sealed with a patented O-ring, rated for up to 8,000km of riding. The gold finish carries a 4-micron anti-corrosion coating that's passed 1000+ hours of salt-spray testing, and it's RoHS\/REACH\/CPSIA compliant. SUMC backs all of this with a wide range of finish colors to match any build.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0;\"\u003e\n\u003ctbody\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;\"\u003eGold\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\/tbody\u003e\n\u003c\/table\u003e\n\u003cp style=\"font-size: 12px; color: #9a9a9a; border-top: 1px solid #e5e5e5; padding-top: 10px;\"\u003eSKU: SMC-S12EL-PRO-GL\u003c\/p\u003e","brand":"SUMC","offers":[{"title":"Default Title","offer_id":67571026034992,"sku":"SMC-S12EL-PRO-GL","price":7200.0,"currency_code":"INR","in_stock":false}],"url":"https:\/\/www.dogoodco.in\/products\/sumc-s12el-pro-chain-12-speed-shimano-gold","provider":"DoGoodCo","version":"1.0","type":"link"}
