Hi,

Had a fun trials ride in sunny Vancouver in November (what a concept!) a few
weekends ago. Here’s a picture from it:

Kris, That’s amazing! How big was the huge gap on the UNiVERsE video? I only saw
a clip on www.biketrials.com. jeff On Wed, 6 Dec 2000 10:32:02 -0800 (PST) Kris

No it was a 24" doublewide with a 3" tire. I prefer this setup for pure trials
(as opposed to street style) because the longer cranks give better torquing
power, which helps a lot for gapping railings.

This is true, but there is an additional limiting factor: the minimum
acceptable distance between your pedals and the ground. Since overall your
pedals are higher off the ground with a 24"wheel and 3" tire compared to a 20"
tire, you can get a higher torquing power (ie larger ratio between crank arm
length and wheel diameter) while still keeping your pedals from being too close
to the ground.

Also it is a bit more forgiving gapping railings with a larger tire, because
there is a slightly larger contact area where your tire contacts the railing.

If you receive something that says “Send this to everyone you know” pretend you
don’t know me.

Theoretical question maybe, but if it would be a 20" and your cranks would be
shorter by the same ratio (20%), then torquing power would be the same? I
imagine it would be more difficult, though, to aim the smaller wheel at the
next railing.
