I just picked up a fuji 450 SE for a very short frind of mine. It has a 27" (630mm) wheel in the back, with a 600A ( ) (541mm) in the front. Completing its strangeness, it has those freaky suntour butterfly shifters. Sorry, no pics. Rest assured however, that this is one strange bicycle. Also! The chainrings ONLY come off from the back! They only use half of a chainring bolt for each spider-arm-thingy! I love this bicycle, and it really is a shame that I am NOT the 5'0" person who gets to ride it.
Anyway, since it is for a beginner, I was going to swap out the drop bars for some risers, swap the cracks for a single ring setup, and build a new rear wheel for it with a sturmey archer hub. Only problem: my hub is 40H. I know that CR18 40H is available in 700C, but it doesn't seem to come in 27". Anybody know where I could find something with 630mm diameter and 40H? My other option would be to bite the bullet and use a 700C, but then the brakes might not reach, (these are "long-reach" brakes, and it doesn't look like I can go down 4mm.
Secondly, can you people tell me what you know about these butterfly shifters? I've only seen them once before. Do people hate them? What kind of bikes did they come on? They are accushift-era, which means that they were not stylish compared to shimano, and may have been overlooked by many. Or they might suck. I can't decide, nor ride this bike.
