You're bike is a mark v?
Most threadless forks that are uncut are pretty long. You go to figure they need to accomodate the largest frame size the company has to offer. I know some people that leave a an inch or two extra on the fork so they can change the spacers from above and below the stem.
If you don't want to cut your fork your bike is going to look weird and your want to buy like 8 inches of spacers. It takes about 5 minutes to cut the fork with a pipe cutter, just remember, don't cut too liberally.
