I need some advice on crank arm length, looking to purchase a new campagnolo crank arm set but what is best length to go for, they seem to come in 165 - 175 arm sizes and I'm not sure what to go for and I don't want to make an expensive mistake!!

On a 21 inch frame and I have 27 inch inside leg what is the best approach ??

I like 170s. Your legs are slightly shorter than mine so either of the shorter lengths. 170 I think. What do you ride at the moment?

I'd go for 170 too................it's your size IMHO and certainly BITD the most common so I guess would be the easiest to source.

Track cranks were shorter because the bottom bracket was lower. I guess you are after a strada set though.

Thanks guys I thought as much but was looking for confirmation.

I'm building up a Colnago super frame to replace my aged but lovely Holdsworth special that's too big for me, now I'm older!!

I'll look out for campagnolo record or chorus NOS
