Customer Reviews

Looks great and does it's job.
Can't really say much about a piece of plastic, other than the Topeak DeFender keeps the mud off of my back and looks great, like fenders on an off-road motorcycle. However, remember to carry a hex tool with you in case the fender shifts downwards against the tire after large bumps and drops.

Great in theory, lousy in practice
The basic concept of this fender is simple and straightforward: right out of the package, it will easily attach to any seat pole without the use of tools for quick and easy installation. It uses friction applied by a leather-lined strip of nylon webbing (much like a seatbelt) tightened against the seat pole.

The failure is in the tightening mechanism. The webbing needs to be fed into the turn post, which you then tighten by hand before locking into place. The final tension comes from a latch attached to the end of the webbing; close that latch and the fender is supposed to hold. Except that each and every time I (and all my compatriots) tried, the turn post could not hold the webbing. Not enough friction there!
And that's if you can get the webbing properly threaded through! I managed that feat about 1 every 8 or 9 attempts. Those with nimbler fingers than I managed it a bit more often than I, but the results were always the same; attach to the seat post, close the latch for final tension, shake the bike to test and down went the fender.

Every. Blessed. Time.

And I might not have been as livid as I was if I had tested the tension properly first before I left my house with the thing on. I got about a block away before I felt and heard the fender collapse onto my rear tire while I was accelerating. No one wants to find a problem with their latest purchase while gaining speed on the road, let me tell you.

The salt in the wound on this poorly designed contraption is; while it's designed to attach to your bike without tools you still need an Allen wrench to tighten the screw that maintains the fender's angle. Which means you need a tool.

I'm returning this thing as fast as I can and I will be buying a fender that attaches with a nut/screw set.

Fair
It does what it is designed to do however....you have to mount it up high on your seat post and fasten it very tightly or it falls and rubs your tire. It is easy on easy off, cleans up quickly.
