Product Information
Full details
The Race Face Carbon Crank Boots are a must-have accessory for mountain bikers looking to protect their expensive carbon cranksets from rock strikes and trail debris. Designed for riders who frequent technical, rocky terrain, these durable rubber boots slide over the tips of your crank arms to absorb high-impact damage and prevent structural damage or unsightly chipping. While they offer exceptional protection, they are specifically shaped for carbon cranks, meaning they may not provide a secure fit for certain aluminum or non-standard crank profiles.

FAQs
Will these fit my aluminum cranks?
These boots are designed primarily for the specific dimensions of carbon cranks. While some aluminum models might fit, they are not guaranteed to work unless specifically listed.
Do I need tools to install these?
No, these are friction-fit boots designed to be installed by hand.
Can I leave them on during a bike wash?
Yes, but it is recommended to remove them occasionally to clean out any dirt that may have migrated inside.
Are these sold as a pair?
Yes, they are intended to protect both crank arms and are typically provided as a set.
Do they affect my pedal clearance?
The boots add a negligible amount of thickness and generally do not impact ground clearance for standard mountain biking.
Troubleshooting
Boot feels loose or slides off
Clean the inside of the boot and the crank tip thoroughly, then re-apply to ensure no grease or mud is interfering with the fit.
Difficult to slide onto the crank tip
Ensure the crank model is on the compatibility list. If it is, use a small amount of water to lubricate the surface, then press firmly into place.
Pros and Cons
Pros
- Protects expensive carbon cranks from costly rock strikes
- Extremely easy to install and remove for maintenance
- Broad compatibility with popular crank models
- Durable material resists tears and deformation
Cons
- Not compatible with all aluminum crank arm shapes
- Can trap grit over time, requiring occasional cleaning
- May add slight width to the crank tip depending on clearance
Setup, Compatibility & Care
Installation is straightforward: ensure your crank ends are free of mud, then simply press the boot over the tip until it sits firmly in place. These boots are compatible with:
- Race Face: NEXT, NEXT SL, SIXC, Respond
- SRAM: X01, X9
- Shimano: Saint
- FSA: Gravity models
For care, periodically remove the boots after particularly muddy or wet rides. Debris can become trapped between the rubber and the carbon arm; wiping both the boot interior and the crank surface keeps the fit tight and prevents grit from sanding down the finish over time.
