sorry to barge in on the thread but i too am building up a UO-8, the wedge nut on the quill stem had been tightened so much that the steerer tube was actually mushroomed out. that being said im not looking for a new fork. a guy at the LBS told me not to go for a 700c fork because of "trail" im new to bike terminology so this meant nothing to me. question is, what are the drawbacks of putting 700c fork on a frame meant for a 27''
