Where may i find shorter crank arms?

My Yamaha 2017 started with 175, i am now on 165 on my HT Haibike i am having a hard time finding 155 or at least 160. Thanks for your help. The fit is square.

If you've already worn them down from 175 to 165 with pedal strikes, just keep doing what you're doing and they'll soon be at 160 and then 155. ;-)

I think the shimano steps e6000 cranks fit the tapered square yamaha mounts. You might find some shorter ones of these.

33red,

I searched the forum for "unicycle" because I have heard of this before. Apparently unicycles share some of the same crank specifications as our emtb's, but use a wide array of crank lengths. I noticed in the thread pasted below that a member found, and was using some with the ISIS standard (I'm pretty sure the cranks on my Giant/Yamaha are ISIS); I believe he had to grind a little material off the crank. Good luck!

Thanks! I get a lot of pedal strikes on my FS Haibike SDURO here in rocky Arizona; I might try these crank arms.

I also use 152mm handles. I don't have so many beats on the pedals anymore. I also gave a link EBAY
