Era SL Crank Explained

What makes Era SL ultralight, unscuffable and unequalled?
Play

Unscuffable Wear Plate. Unequaled Performance.

Precision protection where it matters most. Our stainless steel wear plate is strategically minimized and precisely positioned to shield high-wear contact zones caused by rider shoes and the increased articulation of modern clipless pedals. Maximum protection. Minimal grams.

One Size Doesn’t Fit All.

Not all riders are the same and your crank length shouldn’t be either. Some riders prefer a high-cadence spin. Others live to push big watts. To support every riding style, we offer four crank length options from 160mm to 175mm so you can dial in fit, efficiency, and power delivery.

Ride Light. Crank Hard.

At just 354g, Era SL is the lightest mainstream crankset on the market—engineered with the strength and durability to withstand daily abuse. Save weight on your build, rebel against scuffs and unlock your biggest Downcountry days. Backed by a Lifetime Warranty. Crashes included.

Light, stiff, responsive

Light, stiff, responsive, and best of all they feel strong. Have only ridden on local smooth trails so far, but have loved them on the climbs. Cant wait to see how they handle rougher descents!

Frequently asked questions

Does this crankset work with standard mountain bike bottom brackets?

The Era SL Crankset features a 30mm spindle diameter, which is compatible with many modern mountain bike bottom bracket systems.

  • Compatibility: Please note that while the cranks are designed for high performance, you will need to ensure your frame uses a compatible bottom bracket for a 30mm spindle.
  • Chainline Options: They support a 52mm chainline with a standard DM ring or a 55mm chainline with a DMW ring, allowing for versatile drivetrain setups.
  • Note: Please check your specific bike frame and bottom bracket shell requirements, as the bottom bracket itself is sold separately.

What is the Q-factor of the Era SL?

The Q-factor for the Era SL Crankset is 170mm, which is measured including the pedal washers.

How does the wear plate protect the crank arms?

The crankset features a precisely positioned stainless steel wear plate. This minimizes scuffing from shoe rub and pedal articulation in high-contact areas, offering essential protection while adding negligible weight.

Does the design prioritize power transfer efficiency?

Yes, the Era SL is engineered for high-performance riding through a combination of lightweight materials and structural rigidity:

  • 7000-series Aluminum Spindle: The 30mm diameter spindle is crafted from high-strength aluminum alloy, ensuring a stiff and responsive connection between the rider and the drivetrain.
  • UD Carbon Construction: Utilizing high-modulus unidirectional carbon fiber allows for an optimal strength-to-weight ratio, effectively transferring rider input into forward momentum.
  • Optimized Stiffness: The overall architecture is built to handle the torque requirements of Trail and All-Mountain riding, providing a stable platform whether you are spinning at high cadences or pushing hard on technical climbs.
Does this crankset provide a significant weight advantage?

Absolutely. The Era SL is engineered to be the lightest mainstream crankset currently available, weighing in at just 354g. It is specifically designed for riders looking to shave grams from their setup without compromising on performance.

Lifetime Warranty, Crashes Included.

Crashes are part of mountain biking. When they happen, we have your back.
