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)

well, first you need to hit the points of intersect on the frame hard enough that it breaks and falls apart. then youll need some elmers glue, some locktight, a pinch of feces, and a smidgen of hope. then mix those up in a bowl and apply to the ends of your broken frame, then re arrange the geometry to your choosing and, viola, done!

I have heard of slight geometry tweaks by changing the track end angles. Of course that involves cutting, grinding, welding, and painting.

in all seriousness, if you really want a frame with more tight track geometry, it might be more cost effective to just buy a new frame

that fork is already straight and there appears to be not much tire clearance.

It is doable. Smaller rake, shorter crown-to-axle fork will steepen the angles, regretfully lowering the BB, too. You can use eccentric rear hub (ENO by White Industries or, like mine, home brew) to rise/shorten rear end, too. My MTB has very track geo with cyclocross fork, eccentric rear hub and 700c cross wheels.

throw a 650 wheel up front. or trade your frame with someone for what it is that you want.

How did you make your own eccentric rear hub?

hey do you think you could post some pictures of this project? I'm working on converting a mountain bike, and I'm looking to do something similer with it.
