⚡ At a Glance
- • Fit & Spacing: Eight spacers across seven thicknesses, from 1.0mm to 2.5mm
- • Best for: Home mechanics, touring cyclists and small bike workshops for cassette maintenance
- • Not ideal for: Riders needing bespoke, precision-machined spacers for non-standard hubs
The set contains eight aluminium alloy spacers in seven thicknesses designed for fine-tuning cassette position. Compatibility notes reference use with 9-speed cassettes and fitting 7-speed cassettes on 11-speed hubs.
Precise gear alignment – with seven thickness options
Each washer corresponds to a specific thickness (1.0, 1.5, 1.85, 2.0, 2.0, 2.18, 2.35, 2.5mm), allowing selection or stacking to alter freehub-to-cassette spacing. Spacers sit between hub and cassette to correct chainline and spacing.
Fine adjustments restore smoother shifting and lower the chance of skip or chain rub, extending the life of drivetrain components.
Durable performance – with aluminium alloy construction
Manufactured from an aluminium alloy described as wear resistant, designed to tolerate regular cycling loads and exposure to riding conditions. Material choice prioritises corrosion resistance and dimensional stability.
Longer-lasting washers reduce the need for frequent replacements and help maintain consistent gear indexing under load.
Quick roadside fixes – thanks to a lightweight, portable kit
The set is compact and described as lightweight and portable, enabling rapid installation and removal when required. Individual washers are small and stackable for easy storage.
Carrying the set allows fast adjustments during rides, getting a wheel back to smooth operation without workshop downtime.
