I have a friend with an old Torker with splined cranks. Seems to be non-ISIS. Any idea where to buy replacement crank? He’d like to try a different size.
Ok they might be ISIS after all. I have asked my friend for pictures.
In any case does someone here know the history of crank interfaces on torker unicycles?
Good afternoon. I own an old Torker with what looks exactly like an ISIS spline. For reference, it’d is a unistar LX Pro(maroon frame, black decals). Most Torkers have square taper hubs and cranks.
I haven’t tried anything other than the stock 127mm cranks, but I have taken them off and the spline looks like ISIS.

Thanks, I think I will just lend him some cranks and if they cleanly, easily mount it is ISIS. If not… it is not. 
Sounds like a good idea. I hope it works!

To buy two left bicycle spline crancs, Truvativ Blaze for example. To cut it and to drill (one, two or three holes in each)

Ok, it turns out they are ISIS on this uni.
Here it is with some of my 115mm Nimbus VCX ISIS cranks mounted

That would have been a bit beyond me to be honest. Yes, I could have enlisted another friend but in the end… I did not need to. Nonetheless, thanks. It sounds like potentially good advice for someone who could.
