Idler pulley (continued)
Typical idler pulley and chainring alignment
With a SRAM chainring With a Shimano chainring
Adjust the position of the idler pulley
Different chainrings or slight tolerance differences in chainrings may require the idler pulley and spacers to be repositioned to
align the pulley with the chainring. To achieve alignment, do one or a combination of the following:
Flip the idler pulley. Position the 3.5mm and 4.5mm
spacers on either side of the idler pulley.
Position the 0.5mm spacer on
either side of the idler pulley.
Tools
• 6mm hex tool
• Torque wrench with 6mm hex bit
• Grease
1. Inspect the current installation to determine the
distance the idler pulley must be shifted to align with
the chainring.
2. Removetheidlerbolt(8).
3. Removetheidlerpulley(1)andspacers(5,6and7)
from the chainstay.
4. Reassemble the components, using the options
shown in the three illustrations above, to shift the
position of the idler.
Notice: When repositioning the components, all
spacersmustbeusedinthenalconguration.
5. Applygreasetotheshoulderoftheidlerbolt(8).
6. Place the assembled components into position in the
chainstay.

Adjust the geometry
FliptherockerpivotMinoLinkchiptochangethebike’sgeometrytotyourridingstyleortheterrain.FlippingtheMinoLink
chip from the high to the low position slackens the geometry by moving the head tube angle back 0.5° and lowering the bot-
tom bracket up to 9mm.
Mino Link high Mino Link low
Position the chip with the Mino Link logo to the back Position the chip with the Mino Link logo to the front
• Creates a steeper head tube angle
• Pulls in the front fork for quicker steering
• Raises the bottom bracket for improved climbing
Use this position when using 27.5"wheels or a 29"wheel
up front and a 27.5"wheel in the back.
• Creates a slacker head tube angle
• Pushes out the front fork for slower steering that is
more stable at high speed
• Lowers the bottom bracket for more stability
Tools
• 5mm hex tool
1. With the bike on the ground, loosen and remove one Mino Link chip.
2. Loosen and remove the other Mino Link chip.
3. Position the bike:
Mino Link high: Lift the bike by the seat tube. This
will pull the rear triangle up and forward.
Mino Link low: With the chips removed, gravity will
pull the rear triangle down and back.
4. Place one Mino Link chip into the desired position.
Slightly tighten the Mino Link bolt.
5. Install the other Mino Link chip into the same posi-
tion. Slightly tighten the Mino Link bolt.
6. TorquebothMinoLinkboltsto17Nm.
