Assembly / Installation:
- Prototipo Works strongly recommends the use of an anti seize assembly lubricant during the installation of our hardware. An anti seize assembly lubricant helps prevent seizing, galling, cold-welding, and the fusing of metal on metal threaded components. Ideal for salty environments, humid environments, in the presence of water, moisture, sweat and ingress.
- Please ensure all mating threads and installation tools are the correct size, are clean, free of damaging burrs and inserted straight.
- Maximum Torque 3-5Nm. DO NOT OVERTIGHTEN.
- If unsure if it will fit correctly on your bicycle, please contact us.
