I run a 20.75 frame and replacing my cranks because I am switching to LHD. Just recently got back into bmx after being out of it for a few years. just looking to get some input on average/common sizes for parts for a 20.75 frame. 175mm cranks? I'm just under 5'9".

Glad to be back, missed riding. Need some new parts to get caught up.

It's 100% personal preference. Most bikes nowdays come with 170mm - 175mm cranks, though.
