How to repair a Suntour SF11 fork and where to find parts?

Alesq50 · 2026-05-20

Hi everyone, Happy owner of a Pegasus Estremo bike with a Rohloff hub, which is giving me trouble with the SF11-NCX-FT-E-LITE 700C TS 300/0 fork (serial number TD01329060). It’s starting to show its age, and I’d like to repair it to extend the life of my beloved bike.

The suspension is gone, and there’s an oil leak from the seals.

Does anyone know how to repair it? Where can I find parts that are about fifteen years old? Or where to find an identical replacement fork? Just to clarify, the Magura HS11 brakes are mounted using Firm Tech, meaning they’re on pivots behind the fork, facing the frame.

Thanks for your help! Have a great day, Alexandre
