Campagnolo Crank Record 12 speed 172.5mm 34-50
The new record 12x2 speed cranket set: a new hole -free design of the crank that optimizes aerodynamics. The new record 12x2 speed-cranket of carbon fiber with unidirectional finish guarantees continuity with the finish of the entire group, while the Ultra-Torque bracket system on the steel axis is retained for perfect power transmission.
The new record 12x2 speed cranket can be installed on any type of frame, whether it is used with disc brakes or not, because it optimizes the chain line on the frame with a rear lens of 130, 135 or 142 millimeters , Without this consequences, the Q-Factor that remains constant at 145.5 millimeters. The innovative design of the outer chain leaf ensures faster and quieter derailing thanks to the preformed pen.
The symmetrical design of the inner teeth of the chain top provides improved stability with chain transitions. The double wheel measuring standards (112 and 145 millimeters) make it possible to reduce the weight by making more use of carbon fiber. There are eight confirmation screws for increased structure stiffness. The varying number of pens for each of the three chainring leaf combinations (34/50, 36/52, 39/53) facilitates the shifting thanks to the optimized free strokes that belong to each combination. The special drains on the inside of the outer chainrings optimize the performance when switching back in blind corners.
