so im building up a 2003 Mercian for my gf to tour on and ive run into a strange problem with the stem. i just bought a nitto technomic and it wont fit into the fork tube. its a 22.2 quill stem.. strangely other 22.2 stems fit no problem?! the bike is a 56cm so theres plenty of steer tube. it goes in about an inch past the wedge and then gets stuck. once again, other 22.2 stems go in all the way so theres nothing on the inside obstructing it. on that same note ive also discovered other 22.2 stems that didnt fit aswell.. im scratching my head on this one. should i sand down the stem? id really rather not mess with the fork. has anyone ran into this problem before?
for the record im a pretty experienced mechanic so yes i loosened the quill and lubricated the stem, etc.
thanks in advance!
