Ahhh ok, so with a bit of modification in theory I could fit any bmx crank (as long as it has the micro drive...) this is good to know. Thanks for advice on the 175mm length, it’s true I do also see lots of riders using them, I’m still confused as to why Inspired only made one length though? It must make a difference if you’re say 6”2 or 5”7 for example. I think I’ll also go for 22:16, seems like a popular / standard choice for street trials, I do wonder if a 25t would give a cool BMX vibe to the bike though, like at skateparks or pulling bmx style moves... I’ve just paint stripped my Inspired arcade frame and fork and polished it to a Raw effect... it’s looink ‘sick’ haha
