RECOMMENDATIONS

The ALUGEAR Spider is mounted to the crank arm using 8 bolts 

The recommended tightening torque for the spider mounting bolts is 4 Nm. Tool holder: T20 Torx

Mounting ALUGEAR chainrings:

1X and 2X chainrings can be installed using the ALUGEAR Cover and ALUGEAR Bolts and Nuts

The recommended tightening torque for these bolts is not more than 10 Nm

Use only original ALUGEAR bolts, as bolts from other manufacturers may differ in length or thread pitch, which could lead to component damage 

Mounting Shimano chainrings:

Chainrings can be mounted using ALUGEAR bolts or Shimano bolts

In this case, the bolts thread directly into the Shimano chainring

The recommended tightening torque is not more than 10 Nm

Use a torque wrench for precise tightening
