Crank arm length ?

[jaguarking]

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

Very difficult to get old campag road cranks in 165mm

And campagnolo crank arm sets go up to 180mm!!!
