I recently invested in some Classic-Cycle.com fatbike fenders in an attempt to upgrade from my previous fender setup. To help others anticipate what they might encounter if they‘d like to do the same, here’s a little info on my experience. The fenders I bought were the widest ones they sell (“Fat Bike Plastic Fender Set 26 x 4.0 - 4.8 124mm Black Matte with Stays Extra Wide,” Item# 1509, ~$78 US plus ~$35 shipping; took about a month for delivery to the US from Germany). They look great and are well-made, but they were a challenge to install due to:
(1) lack of fender mounting holes on both my fork (Manitou Mastodon) and my frame (a medium/18” 2018 Fatback Skookum). The “universal clip holder brackets” that I purchased from Classic Cycle (“39mm”) in addition to the fenders were too small for my Mastodon (~44mm in diameter), and too large/not flexible enough for my rectagular seatstays. I tried various sizes of hose clamps (failed), but finally found some “P-clamps” on Amazon that, with some rubber tape underneath, held well enough to anchor the fender mounting struts (1.5” diameter P-clamps for the Mastodon, 1” for the seatstays).
(2) lack of wheel/tire clearance, especially with my 100mm rims/studded Surly Bud 4.8” (front) & studded Surly Lou 4.8” winter wheels. The fit on my “summer” wheel setup using Bud (front) & Schwalbe Jumbo Jim 4.8” (rear) on 65mm rims wasn’t a whole lot better. I ended up cutting slots in the fenders with a Dremel tool at the seatstay yoke and at the Mastodon’s brace to create some additional space (someone more skilled at use of a Dremel could undoubtedly make a better-fitting cut than I did). I also used the Dremel to cut small slots in the fender to secure it with zipties where needed.
So, the Classic Cycle fender project ended up taking a lot more work than I expected, but I’ve been happy with the results. The protection from mud buildup is vastly better than what I was getting with the collection of Dave’s Mud Shovel/MukkyNuts fenders that I had previously cobbled together in an attempt to get good coverage. I do get brief contact of the rear fender struts with the tire side knobs while landing drops, particularly if the drop is in a turn, where you might also be leaning the bike. I’ve only had the fenders installed for a couple of weeks, so it’s too soon to tell whether mud accumulation or some other problem will become an issue with this fender setup...but, I’m optimistic!
