Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Single speed death trap. HELP! Why is my bike posessed?? Newbie question Track geo

I just finished putting this together. Yeah I know, it is probably not a Cinelli. This thing has tried to kill me three times already! Good news: It rides like the wind and has incredible response when I jump on it. This thing flies! Bad news: I can't control this thing. It doesn't steer well- what I mean is, I feel like I am going to dump it when I try to manouver this thing at speed. Not insane speed, but good spirited riding. I can't make turns without slowing WAY down. Had to go off the road yesterday doing a a gentle curve at about 15 mph. Is there something wrong with the frame geometry on this thing? Can you tell from the pictures anything fundamentally wrong with this bike?? Thanks, folks. --Andy

Sorry.... I can't figure out how to add the photos. I'll try again later.

Define what you mean by "...going to dump it when try to manouver this thing at speed"? Can you be a little more specific?

Also try tinypic.com to upload your photos.

Yup. That's what I'm thinking.

A ball-bearing headset that's too tight will cause the handling to be very erratic. It will feel like you are riding on a half-inflated front tire.

Wouldn't a loose be misaligned with the front fork and wheel?
I mean, a loose stem would be easily be spotted when someone is eyeing down on it.

I didn't think it was plausible, really... I just think it's hilarious to imagine riding a bike with a spinning stem.
