Excess Center Lock ISO Adapter

Overview

The Excess Center Lock ISO Adapter allows the use of a 6 bolt disc brake rotor on a center lock hub. This is needed to convert a center lock rear hub, like the ones used on the Excess complete wheel range, to set the hub up to use a disc rotor and disc brake setup. The adapter enables compatibility between center lock hubs and the more widely available 6 bolt rotor standard.

Key Features

• Center Lock to 6 Bolt Conversion — Allows installation of 6 bolt disc rotors on center lock hubs; provides rotor standard flexibility

• Aluminum Alloy Construction — Lightweight and durable body material; precision machined for accurate fitment

• Compact Design — Size: approximately 52x52x9mm; minimal stack height for proper caliper alignment

• Lightweight — Net weight of approximately 27g; minimal rotational weight penalty

• Standard Tool Fitment — Adapter uses the same tool as outboard bottom bracket tool; no specialized tools required for installation or removal

• Hub Compatibility — Designed for center lock hubs that accept adapters, such as Excess XLS hubs

• Net weight: Approximately 27g

• Center distance: 44mm between six bolt holes

• Tool interface: Same as outboard bottom bracket tool

• Purpose: Install on center lock hub to accept 6 bolt disc rotors

Compatibility & Ideal Use Cases

Designed specifically to convert center lock hubs to accept 6 bolt disc rotors. Compatible with center lock hubs that accept adapters, such as Excess XLS hubs used on the Excess complete wheel range. Use only with standard 6 bolt (ISO) disc rotors. Not suitable for direct mount or other rotor mounting standards. Verify 44mm bolt hole spacing on rotor before installation. The adapter positions the rotor correctly for proper caliper alignment. Essential part for setting up disc brake systems on center lock hub wheels. Suitable for BMX racing, mountain biking, and other disc brake applications where rotor standard conversion is needed. Installation uses standard outboard bottom bracket tool for ease of service. Pair with appropriate 6 bolt disc rotors and compatible disc brake calipers. Not compatible with floating or oversized rotor designs without verifying fitment. Ensure proper torque specifications when securing the adapter. The low profile design maintains proper chainline and caliper alignment.
