FAQs

Will these fit a 29er mountain bike?

Yes, the M1 and XC11 set is designed to provide coverage for various wheel sizes used in mountain biking.

Can I use the rear fender with a dropper post?

The XC11 is compatible with most seatposts, but ensure the clamp does not interfere with the dropper mechanism or limit its travel.

What is the weight of the set?

The set is constructed to be lightweight, though specific gram weight varies slightly based on mounting adjustments.

Is the M1 fender compatible with rigid forks?

The M1 is optimized for standard suspension fork steerers, but may not fit all rigid fork designs if they lack a standard crown hole.

Do I need any tools to install these?

No, the entire system is designed for tool-free, quick-release installation.

Troubleshooting

Rear fender rotates or slips on the seatpost during a ride

Ensure the slip-joint clamp is fully tightened and check if a rubber shim is needed to compensate for smaller diameter seatposts.

Front fender wobbles while riding

Verify that the quick-release mounting plug is fully expanded and seated firmly inside the fork steerer tube.

Pros and Cons

Pros

Tool-free quick-release mounting for rapid installation
High-impact plastic offers excellent durability on rugged trails
Polished underside significantly reduces mud buildup
Highly adjustable pivot points ensure a custom fit for various frame geometries

Cons

Not suitable for seatposts smaller than 25.4 mm or larger than 34.9 mm
Front fender attachment may interfere with some specific fork-mounted accessories
Plastic construction, while durable, can be prone to scuffing in heavy crashes

Setup, Compatibility & Care

Installation of the DeFender set is designed to be straightforward and tool-free. For the M1 front fender, insert the quick-release mount into the fork steerer tube and tighten until secure. The XC11 rear fender uses a slip-joint clamp; simply open the clamp, wrap it around the seatpost, and tighten the mechanism until it no longer rotates.

Compatibility:

Front: All standard mountain bike forks (including tapered).
Rear: Seatposts ranging from 25.4 mm to 34.9 mm.

Care instructions are simple: after muddy rides, rinse the fenders with water. Because of the polished finish, debris usually slides off easily. Avoid using harsh chemical solvents that could degrade the plastic over time.
