So i off-squared my crank arms, right? i'm in my local bike shop and i ask the guy if he has any cranks that could replace mine. he looks at my uni for a couple seconds before telling me "there are two left side cranks on your unicycle and one of them has been rethreaded for a right side pedal." is this standard on unicycles? if so, why? if no, could this be why my cranks broke?
I doubt it was two left cranks, unless they were both left threads. Maybe he was mistaken, and he thought that because the right crank had no sprocket thingy, that it was a left crank originally. It is standard for unicycles to have left and right cranks, just like bikes except without the sprocket for a chain.
I've bent a right crank before, and the bike shop (I didn't know of any other place to buy parts) sold me a second left crank. I rode around with two left cranks and two left pedals. Strangely I never had any problem with the right left crank's pedal coming undone because I did it up nice and tight. Eventually I snapped both sides of the cheap taiwanese hub.
You can order unicycle cranks from specialist unicycling shops such as 'Unicycle.com' (unicycle.comunicycle.comOpen ↗). They can also sell you a better unicycle with splined cranks and hub, which will not bend as easily as the crappy soft square taper ones.
