Press Fit Bottom Bracket Installation
1. Ensure that Bottom Bracket (BB) shell ① is clean and free of metal chips, dirt, and excess paint.
Note: BB-92 is for MTB cranksets only. BB86 is for road cranksets only. Refer to “ Crankset Specification ” chart to ensure bottom bracket and crankset compatibility before continuing.
2. Follow assembly order as pictured in above illustrations.
3. Place either Bearing cup ③ with plastic sleeve ② on the Headset press tool ④ as shown. Note: Right and Left bearing cups are the same.
4. Slide the Headset Press tool ④ through the Bottom bracket Shell and place the remaining Bearing Cup ③ with Plastic sleeve ② facing the Bottom bracket shell (Fig.1).
5. Using the Headset Press tool ④ press the bearing cups ③ with Plastic Center Sleeve ② into the BB shell. Tighten until the thrust face of the Bearing Cup ③ is flush with the outer face of the Bottom Bracket shell
① (Fig.2). Note: Be certain that the bearing cups and tool faces are aligned and square otherwise damage to the plastic covers and bottom bracket shell may occur.
6. When Bottom Bracket is fully installed unscrew Headset Press tool and carefully remove from the Bottom bracket.
7. Check bearings for rotational smoothness. If bearings feel rough, it may be an indication the cups are not perfectly aligned in the bottom bracket shell. It may be necessary to remove and reinstall the bearings to
be assured bearing alignment in the bottom bracket shell.

Crankset Installation
1. Ensure the Bottom Bracket Shell ① is BB86 (for Road) and BB92 (for MTB) compatible and has an overall width of 86.5mm (for Road) and 92mm (for MTB).
2. Follow assembly order as pictured above. (Note: bottom bracket should be already installed as instructed earlier in instruction).
3. Apply a thin layer of grease on the spindle surfaces which contact bearing. Insert the drive crank into the right side of BB shell. Take great care not to damage the plastic covers of the bearing cups.
4. Apply a thin layer of grease on the engagement teeth the left spindle. (Note: Engagement teeth should be fully exposed on the left, non-drive side of the bottom bracket. Alloy cranksets do not require a wave spring
washer).
5. Install the non-drive crankarm ⑤. Make sure engagement teeth of spindle and left arm insert are seated correctly before tightening crankbolts ④ & ⑥. Make sure spindle engages the non-drive arm fully. The spindle
must be inserted passed the center of the outermost pinch bolt for proper engagement. If spindle engagement is not sufficient, the crankarm can loosen while riding causing loss of control of bicycle
and potential injury.
6. Tighten M18 endbolt ④ to a torque of 7.1-15 kgf.cm / 0.7-1.5 Nm / 6.2-13 in.lbs. Always use a calibrated torque wrench to tighten the endbolt.
7. The M6 pinch bolts ⑥ must be tightened by turning each bolt 1 / 2 turn at a time so both bolts tighten evenly to a torque of 110-150 kgf.cm / 10.8-14.7 Nm / 95-130 in.lbs.
