DHX2 Factory DH Metric Trunnion – 2025

Description

Save Weight or Gain Lifespan. Chainrings are an integral part of the drivetrain, but they are also susceptible to wear and need to be replaced periodically. A worn-out ring means less effective chain retention and premature chain wear, leading to poor shifting and more dropped chains on the trail. When purchasing a chainring, the options for riders are a lightweight alloy chainring that wears out quickly, or a hard-wearing steel chainring that more than doubles the weight. Race Face wanted a third option for riders; a chainring with the best of both worlds. Something as light as aluminum, but as longlasting as steel. The Era chainring achieves this.

Play the long game.

The Era ring is made of three parts, letting us use the best-performing material for each. For the teeth, thats stainless steel, which is stronger (and harder) than titanium with a wear life five times that of aluminum.

Dont mess with the best.

The aluminum crank interface is tried, tested and proven on Race Face chainrings. Its light, its durable and with CINCH its easy to swap out ring sizes.

Spidey strength.

Binding it all together is the carbon fiber spider, compressed and co-molded using the same process we developed for Era carbon cranks. This little spider can withstand the equivalent output force of a 5.9L 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.
