    Anyone manage to get full fenders on a Specialized Sirrus?

    Weird design on my 2002 Specialized Sirrus--it's got mounting points for full fenders, the kind that attach with stays, rather than clip-ons. But there are things that make getting fenders on, particularly on the rear wheel, extremely difficult.

    I got some SKS p35's (maybe should have gotten the next size up, but they are supposed to accomodate 28mm tires). And there are at least three difficulties mounting the rear fender:

    1) the clearance between the seatstay bridge and the wheel is too small

    2) the hole drilled into the seatstay bridge is vertical, rather than horizontal, as it is on most other bikes I've seen, and as the fender hardware expects to attach to--did they attach this part incorrectly on my frame?!

    3) there's a part of the front deraileur jutting back that interferes in the space where the fender should attach to the chainstay bridge (which, by the way, is too far back from the wheel relative to the fender clearance

    So I think I'm returning these fenders, but I'm now wondering if, despite the mounting points on the frame, it's impossible to attach full fenders to a sirrus. Anyone done it? What kind? Maybe I should just settle for a clip-on fender, even though that's not what I really want?

    I have seen other riders solve these clearance problems by cutting the fender at the tight clearance point & attaching each piece with zip ties. I have a Bianchi Trofeo that has the same stay attachments with very little clearance at the seatstay bridge & while i was just able to get the necessary clearance, I'm thinking of splitting the rear fender so it can better follow the wheel curve & leave maximum clearance at the bridge.

    I have those black fenders that I got from Performance that fit over my tires, and I haven't had a problem with my specialized sirrus (also an '02). It's the ones that screw onto the seatpost. You may want to try that one out if yours don't work.

    At the chainstay bridge, I drilled a small hole 1.5cm from the tip of the fender, and used a zip tie around the bridge.
    Regarding the tight clearance and vertical hole, these are both design flaws, now corrected. Perhaps you should write to Specialized and see how they would solve the problem.

    If you call Specialized you will get much better service! Or better yet take it to the LBS you bought it at and let them install them. If you bought the fenders and bike from the same LBS they shouldn't charge you anything and will make sure its working right.

    Thanks for the replies. I will try to get in touch with Specialized and see what they have to say--some of the problems definitely seem to be due to design flaws. If they have anything interesting to say, I'll report back.

    Seems like a lot of people have to cut up their fenders or resort to improvised attaching hardware to make them work on their bikes. Maybe this is one area where mail-order DIY is a bit of a risk, and the LBS could be a better route, as seely suggests.

    I installed Planet Bike road fenders on my Sirrus with no problems.

    PurpleK, which ones do you have:

    Freddy Hybrid Cycling Fender
    or
    35mm Road Freddy Cycling Fender...

    I also have a 04 sirrus with 35c michelin transworld sprint tires and I want to put fenders. I tried one pair (can't remember the brand) but didn't have enough clearance...so I wanna try planet bike fenders
