|I have a cannondale size 58 caad 4 frame and would like to mount a set of 700x28 cross tires on a set of mavic cxp21 rims.(snow riding and commuting this winter) Is the tire size to wide for my road frame? any good rules of thumb or suggestions.

|I've run a pair of 700x30 Ritchey Cross tires on my road frame (Serotta 91 vintage) with no problem. You'll have a few (3 to 5) mm clearance between the brake and the tires, but it shold not rub. You should also have plenty of clearance around the chainstays.

|Not to be contrary, but in my experience steel road bikes tend to have a wee bit more space around the wheels, since the frame has smaller tubes. Alum and carbon bikes tend to have less clearence. Maybe the best thing to do is to measure as best you can, or wait for another Cannondale owner to show up here.
With my steel bike I started out with 35s, found that they almost fit (ah crap), put the price tags back on them and returned them for 30s, and all was well. Local bike shops are our friends.

Great point. I forgot about the thicker tube chainstays on Al frames. Best way is to measure and try it out.

|I have a 56cm Cannondale R300 that I have outfitted with Mavic MA3 rims and 27cm Vittora CX tires. They fit just fine . I also have a part of 28c Vreidsten (sp) that fit also , with about 4 mm clearence in the rear.
30c is to big . I try'd Michelin Wildgrippers CX and they didn't fit at all in the rear.

|The problem I have seen is not with the width at the stays, but rather with the brake arch. If you are running Shimano dual pivot sidepulls (the most common), the top of the tire may rub on the brake arch. Depends of course on the height of the tire.|| |
