Before I spend my entire working day digging through the archives, does anyone know what lengths you could get XT M737 cranks in? I have 175mm at the moment and have been suffering some knee problems after long rides; back in the day I used to ride 170mm (purely because that's all I had) so I'm wondering if it's related. Did they ever make a 170mm 737? (I won't even being to ask where to source one - it's going to be a long wait I'm sure!)
Cheers,
