[QUOTE=surgtech1956;208506]My hybrid frame is 15" and seems fine - I think sometimes I'm in between sizes, my mtn bike was a 17.5 and seemed too big. QUOTE]
The mountain bike may have been too big cuz the top tube was too long. An advantage of the small front wheel is that it will have a more proportionally sized top tube. I think you can't go wrong on it. If it really doesn't fit you can probably make money selling it either here on TE or at the terry website.
