Editor’s note: We got the following product review from longtime reader/commenter Raiyn Storm. He has graciously allowed us to post his thoughts and photos here for you. As he purchased the fenders for his own use, we’re going to forgo that pesky FTC disclaimer that normally appears at the end of our reviews here on Bikecommuters.com. And, as far as we can tell, the following is the first online review of this particular fender set…so enjoy!

I recently purchased a set of Bontrager Interchange Nebula fenders to use on my Town bike. I chose these fenders specifically because I wanted the protection that only full coverage fenders can provide with the ability to remove or re-attach them at a moment’s notice. While there are other “quick release fenders on the market I found their coverage to be insufficient for my needs. I tend to use my bike as a jack of all trades so being able to remove the fenders quickly and without tools is a plus in my book.

Below is the description of the fenders from Bontrager’s website:

Features

* After initial installation, the Interchange system allows subsequent removal and application in seconds
without tools
* Lightweight polycarbonate fenders are weather and impact resistant
* Adjustable, oversized aluminum stays ensure a custom and secure fit
* Rear frame mounted fenders fit under racks, out of the way of trunk bags and panniers
* Includes integrated mudflaps designed for maximum water dispersion
* Can be fully disassembled for easy recycling

Basic installation is fairly straightforward and requires a 4mm Allen wrench, 8 mm open end wrench and a #2 Phillips screwdriver.

The Interchange Nebulas are attached by means of a quick release bracket in the front and tensioned chain and seatstay bridge mounts and clips. In addition, the fender stays are attached to a corresponding bolt-on “mushroom” (bolted to the fender eyelet) by means of a snap-on socket. Installation is a little more involved than regular fenders because the socket mount is threaded to adjust in and out of the fender stay and will need to be adjusted for your setup. Once adjusted, the socket is secured by a jam nut.

Even though the included directions seemed less helpful than something you’d get from IKEA, I have confidence that most people will be able to pull off the basic installation with minimal problems. I, on the other hand, had a few minor changes to make.
Knowing that I had a suspension corrected fork, I needed a way to get the fender close enough to the tire to function properly and still look right. I had initially planned an elaborate kludge involving P-clamps and plenty of extra hardware, but it proved to be overkill due to the relatively short axle to crown measurement of my Surly 1×1 fork. I ended up following what I feel to be a cliché by adding a (thankfully) small piece of metal to drop it to the correct height for my fork / tire combination. Another modification to the basic install was forced due to the seat stay bolt hole pointing down instead of being a horizontal hole. Because of this I decided to bolt it to my brake booster instead which still allowed it to follow the correct arc while potentially adding support due to it’s more centralized location on the fender arc.

I was able to try the fenders out recently in some mildly rainy conditions in the area and I’d say that the coverage provided by the front fender is better than one would expect from a typical set of detachable fenders, rivaling that of some of the best names in the business. Perhaps aesthetically I wasn’t as happy with the projection ahead of the front fork as I could have been but the coverage from the business end of the front fender and mudflap drops well below the bottom bracket making up for what I feel is a fairly stubby front projection when compared to more traditional fenders. I felt that the rear behaved as a normal bolt-on fender would in that you wouldn’t notice any real difference between it and the easily removed Nebula.

The Interchange Nebula’s are priced around $50 – $55 depending on the shop. The price is fairly in line with the better bolt-on fenders on the planet but offers the versatility of super quick removal for sunny days or for just putting your bike in the trunk after a late night at work.
