TO ENSURE SAFETY

For Installation to the Bicycle, and Maintenance:

• When installing the pedals, apply a small amount of grease to the threads to prevent the pedals from seizing. Use a torque wrench to securely tighten

the pedals. Tightening torque is 35 - 55 N·m. The right crank arm has a right-hand thread, and the left crank arm has a left-hand thread.

• If the bottom bracket shell is not parallel, gear shifting performance will drop.

• If the chain keeps coming off the gears during use, replace the chainrings and the chain.

HOLLOWTECH II / 2-piece crankset

• When installing the left and right cups, apply grease and be sure to install the inner cover. Otherwise the waterproofing performance will worsen.

• To ensure the best performance, be sure to use only the recommended type of chain.

• If a squeaking noise is heard coming from the bottom bracket axle and the left crank arm connector, apply grease to the fastening section, then

tighten it to the specified torque.

• If you feel any looseness in the bearings, the bottom bracket should be replaced.

• Use the specified chainring combination. If other chainring combinations are used, it can create poor shifting and cause the chain to jam, resulting in

damage to the bicycle.

B type crankset

• Use B type cranksets with specially designed frames.
