    Low profile 700x28c tires??

    Crashed my Fuji road bike last weekend and had to replace the fork. Bought an Alpha Q CS-20 off of eBay. Nice fork, looks nice on the bike and fits great EXCEPT that the bridge is significantly lower than the original Fuji fork and now my 28c tires are rubbing on the underside of the fork. I have another set of wheels with 25c tires and they fit fine but I'd like to have the extra width of the 28s. Any recommendations for a low-profile 28c road tire or a 25c that runs a little wider? Thanks.

    I think that if you ran low profile 28's, there would be no advantage over standard 25's. Are you looking for more straight line traction, I would suggest shifting to the next higher gear.

    I think some companies are marketing 26mm...

    Are low profile bicycle tires even a thing? I'm thinking not.

    Stick with the 25's, or like rideit said 26's. I know Compass makes a 26, and if they do I'm pretty sure others do as well.

    You can't really think in terms of car tires other than regarding the rubber that's glued or vulcanized on. The rubber can be flat or sort of V shaped or whatever but the tires themselves are flexible all the way around so a given width will be a given height with all tires (other than the difference in rubber thickness).

    Vittoria corsas are one that is pretty low for it's width because the rubber (tread) they glue on is thin.

    Wider rims might change a little. But as the light bulb effect goes away as the rim gets wider tires actually get higher profile until a certain point where they start getting lower.

    Not all tires companies measure the same. The bottom line here is you can fit what you can fit regardless of that mm number is printed on the side of the tire.

    I don't think Veloflex makes a 28mm clincher but if they did you could probably use it because their tires are smaller than advertised. But if a certain 28mm fits and another doesn't that isn't because the one that does has a lower profile it's because it's a smaller tires (aside from what I was saying about tread).

    With the exception of tread thickness, bicyle tires have an essentially round shape from rim edge to rim edge unless you get quite extreme on rim width vs. tire size. Therefore the only way you are going to get more clearance from a 28 is either thinner tread or a tire that is simply sized smaller despite what it says on the sidewall. Given that your tire will inevitably pick up small stones and other road debris, it's not a good idea to be riding a tire that is just an mm or so from the fork crown.

    I had a front wheel get jammed by a pebble, it felt like the brake was locked. I donít need that much excitement!
