tire clearance fork issue...


so i have been slowly building up a track frame....

bought a 700x28 sized tire off teh interwebz (fyxation), however my fork doesn't have enough clearance for it by an extremely small margin. in fact the wheel could feasibly spin, but not without minor rubbing at the top of the tire.

since i have thrown said tire on another bike. really like the tire, but would like it more on the FG build.

so my question is this:

is it possible to shave the underside of the fork bridge somehow to create some clearance?
is this a horrible idea?
it dosn't seem like it would be too detrimental to the fork integrity...im thinking 3/16ths of an inch is how much clearance would work...

if this is something people do/have done, well....how is it done? best procedure? tools? etc...

or is the only real fix to get a new fork, or different tire? (i have another tire to use, but would prefer this one)

if this isn't feasible, i guess it stays on my current bike.

thanks in advance for any help!

Most road and track forks are made to be used with 23mm or smaller tires. Using a 23mm tire is the easiest solution here.

Do NOT shave the fork. Get another tire.

not feasible.

possible work arounds...
1: get new fork that has clearance
2: get 650b wheel and appropriate tire, would require long reach brakes.
3: get thinner tire.
Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

Yes, it may be.

I like to run 25's on my bike which it does not fit on my fork. Once you file off the lawyer tabs, it will allow 1/8" to 3/16" of vertical play. Front wheel carries about 20% of weight, so given that bolts are tighten up to spec there's really nothing to worry about.
