Tackled the winter bike today. I had tried and failed to refit the clip-on crud roadracer mk2 guards that I used quite succesfully last year. Unfortunately since then I've gone to 28mm tires on the Roubaix and despite my best attempts it was impossible to get them to fit without rubbing. The clearance on both frame and forks with 28mm tires on this bike is very small so I decided to attempt to fit some 'proper' mudguards instead.
After a quick measure with my trusty calipers and a trip to my LBS I returned with some M-Part Primo 38x700c black guards for the bargain price of £39.99. They seem good quality and the measurements seemed to be pretty close to my requirements.
I tackled the front first as in this instance the forks proved to be the smallest gap I had to deal with so figured if I could get the front to work the back should be a doddle
My first job was to see just how much clearance i had to play with so I test fitted the guard to the fork crown. When refitted the wheel wouldn't budge, bad start
There was however fresh air visible between the guard and the fork, so I marked where the guard was fouling and got to work with the dremel.
I also dremeled flat the top of one of the rivets to try and eek out another half a millimeter. With the wheel back in I found it now turned, but there was a rub that I couldn't get rid of. This called for more drastic action so I drilled out the rivets completely and drilled two new holes for the bracket in front of the fork crown, then refitted the bracket above the guard. A few pop rivets held it back in place and another test fit was succesful, no more rubbing
I then sorted the stays out, the left hand side needed popping in the vice and reshaping slightly to avoid the disc caliper but nothing too serious.
With the front almost done I turned my attention to the rear. Again clearance was tight but nothing a bit of selective dremeling couldn't sort out
I had to cut an oval hole for the seatstay bridge to nestle in to allow the guard to sit high enough to prevent rubbing but this is nicely hidden by the bridge itself.
It took a good couple of hours of tinkering to get it right but it seems spot on now, I'm pretty pleased with it. I won't really know if I've got enough clearance until I ride it but I'm fairly confident. Its certainly better than it was with the Crud's, and the alternative is to sell the bike and buy one with more clearance which I'd rather not do as I'm rather fond of it
