Put the race on the new fork, put all the bearings and other parts together just as if you were going to install the new fork and slide it into the head tube with everything assembled as it should be. Slide any spacers you intend to use and the stem into place. Make sure that the bearings and everything are seated and all parts are settled in the assembled position. Take a marking pen and make a mark on the steerer tube at the top of the steerer clamp. Now take it all apart again. From the mark that you made on the steerer tube measure down 3 to 4 mm, that is where you cut. If your cut is nice and straight that should put you about 2mm below the top of the steerer clamp of the stem. That's the safest way I know of to make sure you don't get it too short. Sometimes this method gives you a steerer tube that's a tad on the long side, but it's alot easier to take a little more off than it is to try and put it back on.

Oct 4, 2002 4:34 AM | | Buy an assortment of stem spacers for 5 bucks. Assemble the whole thing, an then put a largish (1/2 inch) spacer on top of the stem.
Mark thr tube to cut 3-5mm below that. Then cut. Now assemble with the spacer of best fit on top of the stem - even if you really screw up, (Like a crooked cut) you have some steerer left to work with. Unless you are a real WW, the extra b it of steerer above the stem shouldn't matter. Besides - this gives you more versatility if you ever want to use a stem with a bigger clamp, or if you want to try the fork on a frame with a longer head tube.
Good luck! |
