Excess Thru Axle 20mm Rear

Excess Thru Axle 20mm Rear

Product Overview

The Excess Thru Axle is a 20mm rear axle system engineered for 20mm through-axle rear hubs. Including precision washers for custom spacing, it enables fine-tuned wheel alignment and secure retention across varied frame geometries and spacing requirements.

Key Features

• 20mm Thru-Axle Design — Industry-standard 20mm diameter provides secure wheel retention and eliminates axle flex under racing loads
• Precision Washers Included — Four included washers (two 1mm and two 2mm) enable custom spacing adjustments for optimal frame and hub compatibility
• Adjustable Spacing Range — Minimum 130mm to maximum 136mm total length accommodates varied frame rear dropout spacing and hub widths
• Alloy Construction — Lightweight alloy material reduces weight without compromising strength or durability under racing conditions
• Universal Hub Compatibility — Works with any 20mm thru-axle rear hub design without frame or hub modification
• Precision Engineering — Tight tolerances ensure consistent fit and secure wheel alignment across assembly variations
• Custom Fit Capability — Included washer options enable precise spacing for optimal drivetrain geometry and chain tension
