BBUNIV-SHIM Adapter Installation

  1. Start inserting two adapters marked SHIMANO into BB30 or PF30 Bottom bracket by hand. Gently seat adapters using a rubber mallet. Note: BB30 and PF30 dust covers can be removed from the system or left in place. If you choose to use them with the BBUNIV-SHIM, place them between the bearing and the large
    adapter as shown below.
  2. Add the included 24 mm I.D. spacers to both sides. Adjust the number of spacers accordingly for different BB widths and to fine tune chainline. These universal adapters are designed to rest on the bearing surfaces of the crank spindle. For proper interface, using more than 7.5mm of spacers outboard of the adapters is not recommended. 30mm I.D. spacers can be added to inboard of adapter to adjust chainline. Note: The adapter must be inserted a minimum of 7mm into the bearing for proper interface.
  3. Install crank spindle through adapters and tighten crank per manufacturer's instructions.
  4. Check for play in system. If play exists, remove crank arms and add included 24 mm spacers, as needed but no more than 7.5mm on each side. Tighten fix bolts to mfr. spec: Torque: 0.7 - 1.5nm / 6 - 13 in. lbs. Crank should spin freely.

BBMULTI-SRAM Adapter Installation

  1. Identify left and right side SRAM adapters:
    - Right side spacers (24mm I.D.) fit on the BB spindle between the right side adapter and the right crank arm.
    - Left side spacers (30mm I.D.) fit between the left side (22mm I.D.) adapter and the BB shell.
  2. Insert the right side adapter into BB30 or PF30 Bottom bracket by hand. Note: BB30 and PF30 dust covers can be removed from the system or left in place. If you choose to use them with the BBUNIV-SRAM, place them between the bearing and the large adapter on the drive side, and between the bearing and 30mm ID spacers on the non-drive side as shown below. The Multi-Shim adapters are designed to rest on the bearing surfaces of the crank spindle. For proper interface, using more than 7.5mm of spacers outboard of the adapters is not recommended. 30mm I.D. spacers can be added to inboard of adapter to adjust chainline. Note: The adapter must be inserted a minimum of 7mm into the bearing for proper interface.
  3. Install the crank, then insert the left side adapter with (1) 10mm spacer and (1) 5mm spacer and seat it all the way down on the crank. If there is side-to-side play, you may need 24 mm spacers and/or a wave washer on the right side and/or additional 30 mm spacers inserted on the left side adapter. Place the spacers as shown below. Tighten to manufacturer's specification. Crank should spin freely.
