looking for KH spirit 117 138. I recently bought the custom 32 and it came with KH spirits 127 150 I put them on my 24 in mountain uni, but 127 is a little too short and 150 is a little too long.
You could just get a set of 137’s?
Edit: I just saw you want to put a disc brake on it. Carry on.
All sizes of the 2 holes spirit cranks are available in the Australian Unicycle.com store. The brake handle attachment and d’brake is also available.
So if you really want it, buy it from here. Hold onto your other set of cranks for now, they may come in handy some time.
