I've been using 150's for some time - I think I agree with Adrian that a mathematically proportionate reduction in gearing (what I have) is probably overdoing it very slightly, but it feels okay.

I was lead to believe that BMX cranks used a different pedal thread?

But, do they take standard pedals Graham? I believe some do not.

I can not say in generally, but i can say the Blackwidows i use do have standard pedal threads.
I've been using them for about 4yr and swap the pedals between bikes.

Hope you well regards Gd

I just found some 150mm 2 rings cranks on ebay (38T, 48T). I was tempted but they say 1.1Kg which seems a lot, probably cast iron  Tongue. I just weighed my 2 ring 175mm crank set at 724g. I might not notice the weight difference though.

I phoned Spa Cycles because they were advertising 150mm cranks at one time - turned out to be a typo. You got a link Glyn?
