Back to fenders- I did a lot of "internet research" on this a few weeks ago, here's my advice. Look at what SKS & Planet Bike have to offer. After lots of looking, I bought a pair of Planet Bike Cascadia ATB fenders. Their Cascadias are made in sizes for 26", 700(in two different widths), they even make a "29er"size- I think that's a "700" diameter rim with a wide tire. The SKS is good too- but it comes up short on mud flaps. It's also made for different diameter tires, & in several widths.
The Cascadias also come with spacer tubes for bikes with disc brakes. They seem to be well made, & are popular on the bikefoums dot com, as are the SKS fenders & some other Planet Bike models
Whatever you get- if you want to keep most of that dirty ground water off you & your bike be sure to get some full size fenders. Those little clip-ons will, I suspect, be a big disappointment.
Here's a link to the ones I bought(they also come in black- and Planet Bike also has a model with shorter mudflap that comes in black, silver- or *Yellow*, for extra bling!
), got my order just over $75 & so got free shipping from this BikeSomewhere, thru Amazon, plus a 5% discount. Link:
