What Is The Q Factor Of These Cranks?
24 Apr 2016
Hello, I've been searching for the Q factor for these cranks but can't find any information. These are going to be going on a Rohloff equipped bike using a 121mm bottom bracket.
SJS Customer Service:

With a 121mm bottom bracket these cranks have a Q-factor of 174mm.

Square Taper Type?

Would I be correct in assuming that the Middleburn Square Taper MTB Crank Arm is a JIS taper?
SJS Customer Service:

Yes, you would be correct in assuming that. Middleburn cranks are based around a JIS square taper.
