DT Swiss Front Torque Caps - BOOST, 240 hubs

Currently unavailable

Currently unavailable
This guide is for cyclists with DT Swiss BOOST 110 x 15 mm front hubs (specifically older white 180 and all 240 hubs) seeking to enhance front-end stiffness and tracking. The key benefit is a more rigid fork/hub interface, leading to improved steering precision, especially when climbing and cornering. A caveat is that these Torque Caps only fit Rockshox Torque Cap compatible forks. These genuine DT Swiss replacement parts convert standard hubs to a Torque Cap system for enhanced performance.

These Torque Caps are designed for DT Swiss BOOST 110 x 15 mm front hubs, specifically all 240 hubs and older, white 180 hubs.
No, they only fit Rockshox forks that are specifically designed to be compatible with the Torque Cap system.
The primary benefit is an increased contact area between the hub and fork, creating a more rigid interface. This leads to improved stiffness, better steering precision, and a more sure-footed feel.
The caps are designed for Rockshox Torque Cap compatible forks. If your fork is not specifically designed for Torque Caps, they will not provide the intended benefit or may not fit correctly.
No, you use your standard 110 x 15 mm BOOST thru-axle. The Torque Caps replace the standard end caps on your hub.
Consult your fork manufacturer's specifications. Rockshox forks will typically state 'Torque Cap compatible' if they feature this system. The fork dropouts will have a specific shape to interface with the larger Torque Cap end.
Yes, these are sold as a set of two end caps for a front hub.
Ensure you have a compatible DT Swiss 240 series or older white 180 series BOOST 110 x 15 mm hub. These caps are not universal.
These caps are designed exclusively for Rockshox Torque Cap compatible forks. Verify your fork's compatibility. If your fork is not Torque Cap compatible, these caps will not work.
Ensure the Torque Caps are fully seated in the hub and properly engaged with the fork. Double-check that your thru-axle is tightened correctly according to your fork manufacturer's torque specifications.
Confirm that both the hub and fork are indeed Torque Cap compatible. Any incompatibility will negate the intended benefits.
Compatibility Check: Before installation, verify that your DT Swiss front hub is a BOOST 110 x 15 mm model, specifically a 240 series or an older white 180 series hub. Crucially, your front fork *must* be compatible with Rockshox Torque Caps. Check your fork manufacturer's specifications.
Installation:
Care: These are primarily metal components with no moving parts. Clean them with a damp cloth as part of regular bike maintenance. Avoid harsh chemical cleaners, which could potentially damage any seals or finishes. Ensure they remain free of dirt and debris that could impede proper engagement with the fork.
