With the Topeak DeFender XC1 & XC11 29er mudguard set will fit MTB tyres up to 29″ x 2.5″. You get excellent coverage against mud and spray. 

DeFender XC1 Front Mudguard

The DeFender XC1 is lightweight, durable and moto inspired with a two-piece design. This fender attaches to your suspension fork lowers so a close fit to the tyre – so you get improved mud/spray protection. 

A precision clamp secures the front mudguard to the fork’s lower legs and a special safety feature allows it to disengage if a large obstruction enters the wheel.

DeFender XC11 Rear Mudguard

Also lightweight the XC11 is a removable rear MTB mudguard. Multiple pivots offer easy angle adjustment 

while the quick release clamp adjusts to fit ø25.4 – ø34.9mm seatposts. Durable high impact plastic is co-molded to a flexible trailing edge for resistance to impacts while the highly polished underside of the fenders prevents dirt build up in extreme muddy conditions. Fits MTB 29” tires up to 29” x 2.5”.
