Frequently Asked Questions

What makes the Charger 3.1 RC2 damper special?
The Charger 3.1 RC2 damper is an advanced evolution of RockShox’s proven platform, offering a wider adjustment range including High Speed Compression, Low Speed Compression, and Rebound tuning. This allows riders to customize suspension behavior precisely for different trail conditions, enhancing traction, control, and comfort.

How do the ButterCups improve the ride?
ButterCups act as vibration dampers that reduce up to 20% of high-frequency trail chatter. By limiting these vibrations, they help reduce hand and arm fatigue, allowing for longer, more comfortable rides with better control.

Are these forks compatible with all 27.5" mountain bikes?
These forks are designed for 27.5" wheels with a 15x110mm BOOST™ axle standard and a 37mm offset. Compatibility depends on your bike’s axle type and intended travel range, so it’s best to verify your frame specs before purchasing.

Can I adjust the travel length on these forks?
While the forks come in fixed travel options of 120mm, 130mm, and 140mm, volume reducers (tokens) allow for fine-tuning the air spring feel and support, but do not change the actual travel length.

What colors are available?
The forks are offered in two premium finishes: Gloss Black and Gloss Silver, allowing you to match your bike’s aesthetics.
