Fixie riding-help

post #1 of 10
Thread Starter 
All right, you guys are whizzes at figuring out kinetic chain problems.

The problem:
I am attempting to back-modulate the pressure on a fixed gear bike. The right foot is effective, the left foot is not. When I attempt to correct this, the left foot heel swings inwards, so that by the time the pedal reaches 9 o'clock, the heel is on top of the cotter pin.

Very annoying.

Where's your knee?

Didn't notice the (left) knee drifting much; it may have swung outwards but I wasn't really paying attention to it.

I was thinking that the seat might go a little forward, but that might make knee drift, if any, worse?

I'm not a kinetic chain person, but pressing down with the ball of the foot, particularly with the ankle bent, can pull your heel in. What might help is concentrating on aiming that force you supply to the big toe. Aim it straight down through the pedal into the road instead of just pushing on the pedal.
I hope it helps.

Ghost, certainly sounds good, but I haven't been able to make it work yet for braking without getting bounced in the saddle. Actually it sort of worked for the 15 miles I rode with approach shoes/quill pedals but with that combo it is rather easy to figure out which part of the pedal circle to brake with. As soon as I went back to cleats it all went to s again.

Sheesh. Any good visuals? Resisting through the bottom with the toe?

Hmm, could be the footwear; I don't know.

Imagining a spear or arrow pointing out of where you want to direct the force (eg. straight down), tends to line up the bones so they can push in that direction. But I really have NO kinesiology training; I can't even spell it.

PS You wouldn't catch me trying to ride down a mountain without a freewheeling hub.

Most fixie riders use toe clips with two straps. Maybe that's why. Still if you can keep your right foot straight, probably you can learn to keep the left one straight too.

That's cool that you are learning to ride fixed. It's kind of trendy but I'm thinking about getting one. I won't ride it downtown or work on it though. Cotter pin? You must have converted an old ten-speed?

Well, it makes some sense to convert as 27x13/8 rolls pretty durn smooth for those pokey grinding moments, and the stable stage-racer geometry means I don't miss the ability to put knee on top tube.

I'm seeing some pretty interesting effects on overall speed, as I don't dare fall off best pace on long uphill grades.

Right on. 'cause I'm lazy I might buy a Pista off the rack but I think conversion works just as well. There's an old 1970's Atala at my mom's house, maybe I should try to fix it. That would be classier than off the shelf Fuji Track or Bianchi, Langster, etc. Complete fixie brand new just seems so cheap ( around $500?) but I guess conversion is cheaper and good ecology, reuse, recycle, etc. Enjoy the ride!

Not very few miles later, I think I have something here. I did have to crank up the cleat release tension significantly beyond my usual to do it, but I'm now braking on the front using a pull that starts up in the pelvis instead of anywhere in the leg. Wild difference, quills and cleats!
