My Gary Fisher was a Biopace ss conversion when Dekerfintheshed had it.
Personally, I'd rather go to an amateur dentist.

Seems to me that with the lumpy circle that the biopace gives you, it wouldn't go well with the high RPM single speed. I never liked the biopace rings myself because of that.

I ran my single speed road bike with a 48 x 16 setup using a biopace front ring. It required setting up properly to take advantage of the elliptical shape but it worked very well.

I had it set up like this for about a year and used it daily - absolutlely no problems.

Here is the link to the bike>>>

cheers fella,gonna be a hack bike really,mostly offroad.does the chain have a tight spot or does the ovalness take all the slack if you get what i mean :roll:

cheers

The "pull" on the chain doesn't vary, as in the derrailleur does not rock backwards & forwards on a multi speed as you pedal.

There's no tight spot as the chain is always engaged with the same number of teeth.

Spin the pedals of a biopace equipped bike with gears backwards and the cage doesn't move.

What the guys have said above.

I'm building a Hei Hei up for the summer as an offroad single speed and may use a biopace on that.
