Rotor’s ágilis crank now has the option of a mountain double spider with 110/74 spacing
Rotor’s ágilis crank now has the option of a mountain double spider with 110/74 spacing. The new crank will initially be available with a 40/27 Q-Ring chainring combination. The crank bolts use Rotor’s Dual Thread Tech or DTT, where the fixing bolts thread into both the bottom bracket spindle and the crank arm. The design integrates the bolt as a structural component of the crank as apposed to using it as a mere clamping mechanism, says Rotor spokesmen.
