Low Weight, High Impact Resistance

Treat yourself to the fender perfect for any style of riding. From muddy mountain trails to puddle-filled city streets, the Topeak DeFender M1 front fender has got you covered. Made for 27-29" tires, this unique fender features a durable construction as well as a highly polished underside, which makes cleanup a breeze.

The two-pivot arm articulates for improved tire coverage and perfect bike fit. A stiff engineering grade polymer support frame is co-molded to a softer more flexible material at the trailing edge for greater durability and a highly polished underside helps prevent dirt buildup and aids in cleaning.

Nice Looking Fender

I bought this for my 26" MTB. Turns out that the description is incorrect and the one advertised is for a 29". I ended up giving it to a fellow rider and bought the M1 (elsewhere) for the 26" MTB.

The fender looks great on my bike after a couple of minor adjustments to the mounting hardware to get it even with the tire. It has a lot of coverage for a 2.5" tire and keeps the spray down pretty well. I also have the M2 for the back, great fender.

The mounting bracket and hardware is OK but not optimal. A couple of size options for the frame tube would be nice as I had to trim down the tube insert to get it to fit my bike. The bracket and fender attachment points are a bit wobbly (fixed with gaffer's tape). Also, The plastic bracket where the fender attaches WILL snap off if it is tweaked against a tree just right (also fixed with gaffer's tape).
