ERA Direct Mount Wide 12 Speed Shimano Chainring

Play the long game. The Era ring is made of three parts, letting us use the best-performing material for each. For the teeth, that's stainless steel, which is stronger (and harder) than titanium, with a wear life five times that of aluminum.Don't mess with the best. The aluminum crank interface is tried, tested and proven on Race Face chainrings. It's light, it's durable and with CINCH it's easy to swap out ring sizes.Spidey strength. Binding it all together is the carbon fiber spider, joined with our proprietary compression and co-molding processes we used in our Era carbon cranks. This little spider can withstand the equivalent output force of a 5.9-liter Cummins diesel engine. We checked.Everlasting. Light. Era is expected to last five times as long as a typical alloy ring for less than twice the cost. By bonding three parts made from optimal materials, we made a chainring with the weight of aluminum and the lifespan of steel. Era is a chainring without compromise.SpecificationCrank Compatibility: CINCH direct mount cranks.Chain Compatibility: SHI12 - Shimano 12-speed HG+ chains only.NW - other modern 10, 11 and 12-speed chains.Chainline:DM - 52mm (with RF136 spindle)DMW - 55mm (with RF136 spindle)Material: Stainless steel teeth. 7075 aluminum interface.Carbon fibre spiderRing Style Direct mountWeight; 83gWeight Conditions 32T, DMW
