Because of its unique features, the Gary Fisher Cronus requires different or additional assembly techniques, provided here: + Carbon fiber care + Headset bearing installation + Front hub and fork integration + Bottom bracket bearing installation for a variety of bottom bracket types Check for updates. These instructions are written for an experienced mechanic. If you need further information, refer to your bicycle owner’s manual, the instructions in a bicycle mechanic’s handbook, or consult your dealer. Please save these instructions for future reference. 2 | GARY FISHER SERVICE INFORMATION table of contents Working with Carbon Fiber Parts ....................................................................................................................1 Cutting a carbon fiber steerer........................................................................................................................2 To cut the steerer..................................................................................................................................................3 Headset Installation..............................................................................................................................................4 Special Care Information....................................................................................................................................4 Inspecting the Headset.......................................................................................................................................6 Fender Installation..................................................................................................................................................7 FCC Steering System...........................................................................................................................................9 Crankset Installation ..........................................................................................................................................10 SRAM GXP................................................................................................................................................................ 11 Shimano HollowTech............................................................................................................................................14 Campagnolo UltraTorque..................................................................................................................................18 Inspecting the bottom bracket .................................................................................................................... 20 FSA MegaExo AL...................................................................................................................................................21 Cronus Crankset Troubleshooting................................................................................................................24 Bearing play in a GXP crank or bottom bracket assembly ................................................................24 Crank is rubbing or there is excessive drag ........................................................................................... 25 GXP triple crankset can’t be properly preloaded................................................................................. 25 3 | GARY FISHER SERVICE INFORMATION Working with Carbon Fiber Parts Carbon fiber parts are different from metal parts, so they require different treatment. Keep carbon away from sharp edges or excessive pressure Carbon fiber composite can be damaged by sharp edges or clamping mechanisms which cause a point load, or a high pressure area. The clamps on some parts are not compatible with carbon; some stems, seat post clamps, etc. have sharp edges and/or clamps that create pressure points. Before installing any carbon fiber part, or attaching any component to an existing carbon fiber part, make sure the parts or components are carbon-compatible. As carbon frames have gotten lighter and lighter, you can now feel movement in the tubes when you squeeze them. This is normal and no reflection of the strength of the frame. However, repeated compression of the sides of the tubes is not good for them, and could eventually lead to frame damage. Do not squeeze the frame tubing with your fingers, and especially never clamp the tubing in any mechanical device, including car racks. Clean carbon parts before installation With the interfaces of metal parts, grease is used on the clamping surfaces to prevent corrosion. When making adjustments, always grease the threads and shoulders of bolts. Grease reduces corrosion and allows you to achieve the correct tightness without damaging tools. However, with most carbon parts you should avoid grease. If grease is applied to a carbon part that is clamped, the part may slip in the clamp, even at the recommended torque specification. The...
