15x110mm Step Down End Cap Kit, 350/370 Front Hubs

DT Swiss 15x110mm Step Down End Cap Kit for 350/370 Front Hubs is the correct small-parts solution for setting up a compatible DT Swiss 350 or 370 front hub with a 15x110mm (Boost) thru-axle fork interface. By swapping the end caps, the hub’s axle interface matches the fork standard, helping ensure proper wheel fit, rotor alignment, and a clean, serviceable conversion without replacing the entire hub.

• 15x110mm (Boost) compatibility - Converts the hub end-cap interface to match modern Boost fork spacing for correct wheel installation
• Step-down end cap design - Purpose-built end caps intended to achieve the required axle interface for this specific conversion
• DT Swiss 350/370 front hub fit - Designed as a direct-fit end cap kit for compatible DT Swiss front hub models for predictable results during setup
• Cost-effective axle standard change - Updates wheel fit to a different fork standard without the expense of a new front hub or wheel rebuild
