Oh ok. Thanks for the info. The frame is a Centurion Elite GT just in case you guys might know if it was equipped with 700c or 27's. Ill go google around for more info in the mean time.
Edit: According to this brochure
http://www.sheldonbrown.com/centurio...s/20specs.html they were equipped with 27's. Makes my life easier if they do work.
