Bontrager's NCS Fenders offer full coverage for riding in the rain and commuting all-winter long. They're made of a light and super-durable polycarbonate material and. Bontrager's NCS Fenders offer full. Extra coverage and the rear fender is double. Recommended in the 'French' language installation instructions.

Where online can you buy the wider 45c version pictured in this review? I love these fenders! Sturdy, full coverage, convenient, and very lightweitght.

Just make sure you mount the rear one properly in the upper bolt-on bracket provided. Although these mount literally in seconds, I carelessly missed this one step last week, and the fender rotated and I ran over it, making a small crack. Other fenders would have been in pieces. I’ve been using these for 18 months of Manhattan commuting, 30-60 miles a week. Geodimeter Software Tools 2.0. The only other problem was that one of the two front brackets keeps popping off the mount on particularly bumpy streets. I hold it down with the quick-release lever. I intend to buy the same model again, but the 45c version is hard to find.

First, these are NOT the 45mm version. Mine are the 26″ x 60.

Second, I have NO idea how you managed to run over your fender by missing the upper bracket, you’d have had to have missed the chain stay clip as well, and even then I’m having trouble visualizing how this was supposed to have happened. Third, I special ordered mine through one of the local Trek dealers as nobody (not even the dealers) stocked them when I ordered them. As this is a Bontrager (read Trek) product you aren’t likely to find them at Jensonashbareiformancepoint, and I’d direct you to your local Trek dealer. Lastly, I have a sort of update on the fender set. A few months ago I ordered and installed a Topeak Super Tourist DX with Side Bar and promptly discovered that the rear stays of the Interchange fenders were incompatible with rear dogleg of the Topeak rack largely due to the single pair braze on’s provided by my bike’s frame. I ended up having to modify the stay system and rig an new upper mounting bracket off the rack’s light mounting point. Essentially the rear fender is no longer “quick release” though I’ve found that the ability to remove the front fender is FAR more valuable in my situation.

I have just purchased these fenders and am fitting them to a 2012 cannondale caadx tricross bike. I purchased them so I can quicly pop them on for wet UK commutes and remove them for racing and ‘proper’ rides. The problem I have is that the rear mudguard does not easily fit as standard and I thought I’d share as it might be the same on other cannondale frames.

The diagram in with the fender also seems to show two brackets to fit the rear one to the chain stay – although no such bracket comes in the pack. So the rear fender. Firstly The ‘thin’ end of the fender that attaches at the chainstay end of the bike has a little hook on it which is supposed to simply hook onto the horizontal bar at the triangle of frame where the chainstay is.

On the CAADX the frame is beefed up in this area and so the gap of the triangle is smaller and the tube thicker, meaning that the hook doesn’t fit over. (See the inset of the photo above that shows the rear fender for the piece I mean – it’s the first picture after the photo of the components included in the pack – the inset bottom left is the hook bit) As mentioned there are some brackets shown on the diagrams that suggest there are 2 different options to sort this out – however they were not supplied and so this makes no sense!! The stay at this end on the cannondale’s has a screw fitting which corresponds to a hole on the guar at the hook end – however, by screwing it into the frame, I lose the whole USP of being able to quickly remove the fender.
