Safety

⚠️ WARNING: Properly tighten hardware

Always tighten hardware to the specified torque. Over-tightening hardware could deform or break the hardware or components. Under-tightening hardware could cause hardware or components to become loose. Either situation could damage the bicycle and result in injury to the rider.

⚠️ WARNING: Reapply threadlocker

All reused-fasteners with pre-applied threadlocker must be cleaned with isopropyl alcohol and have new threadlocker applied before re-assembly. If threadlocker is not applied, the fasteners may loosen which could damage the bicycle and result in injury to the rider.

⚠️ WARNING

Do not apply grease to the derailleur hanger or bolt. Apply grease to only the thru axle.

This bicycle frame is designed to use a Universal Derailleur Hanger (UDH). The thru axle must be compatible with a UDH and must be M12x1.0 with a 12.7mm thread. The washer is frame-specific. Install only the washer compatible with your frame.

NOTICE: Do not over-tighten. Over-tightening the bolt could cause the hanger to break. For additional information about the UDH, refer to the SRAM user manual at www.sram.com.

Cabling

Zip tie guide

Tips:

• Before inserting the zip tie, bend it in half to create a crease. This will make it easier to wrap the zip tie around the cables and out through the hole.
• Use a hook tool and a pick tool to hold the cables and guide the zip tie around them.

Frame Guards

Downtube Guard Installation

Use isopropyl alcohol to clean the frame surface where the guard (2) attaches. Wait for the alcohol to dry before applying the guard.

Notice: Do not clean the entire frame with isopropyl alcohol. Isopropyl alcohol could damage the paint.
