Hi,
I'm not comfortable with my current STX RC 175 mm (FC-MC33) (very good condition, but too long for me) and I'm looking for 170 mm STX RC crankarms.

Same happens with my White Industries 175 mm + Sugino csii chainrings.
White Industries 170 mm crankarms (or crankset) would also make me happy.

Thanks!

Hi Chris,
Thank you for the pics. !!!!
But I can't read the last digit of the serials (a bit out of focus)
Different series within STX Crank family (FC- MC31/ FC - MC32 / FC - MC33) have different BCD

So, in the second pic , is it FC- MC31, MC32 or MC33??

Thanks!!!!!!!!!!
A.
