140mm cranks

Has anyone tried out the 140mm Lasco Cranks available from Unicycle Source ???

Re: 140mm cranks

Yes, what did you want to do with them?

If you’re into trials, Lasko cranks don’t bend until about 30 inch drops. If you
need more than that, get someone to cut down a set of Shimanos for you. I wish
someone would start selling those.

As for length, 140mm is still a bit long for spin entry. (with a Monty wheel,
20.75 inch outer tire diameter). You have to be careful or the pedal strikes the
ground. A slightly shorter or straighter crankset would help spins.

I’m impressed you got 40" out of steel cranks and 180 lbs. You must land softer
than I do, cuz I’m 150 lbs and never got more than 30" out of my steel cranks.
(Could have been a different brand, of course.)

I agree, several things will affect exact performance. Tire size & inflation,
whether you’re landing on concrete or bark chips, how far out your feet are on
the pedals, weight of the rider, plus how softly you can land. What you really
need is something that can stand up to your hardest hits.

Generally with steel cranks you can bend them back in shape by shifting your
feet as far to the side as possible and hopping on it with your other foot
forward. Definitely not a permanent fix, though.
