Description

If your head bearings keep coming loose no matter how many times you tighten them, the real problem is usually the OEM star nut walking up the steering tube under repeated impacts. The Warp 9 Stem Lock replaces that weak point with a threaded rod that runs the full length of the steering tube, clamping the lower and upper triple clamps together properly — and it adds fender mounting threads you didn't have before.

Compatible With:

  • Sur-Ron Light Bee
  • Talaria Sting / XXX / MX3 / MX4
  • E-Ride Pro
  • forks without a fender mount on the lower clamps

Features:

  • Full-length threaded rod compresses lower to upper triple clamp, keeping head bearings tight for good
  • Fixes the root cause of star-nut creep instead of just re-tightening the symptom
  • Lower machined retaining nut includes 2 M5 threads for fender mounting
  • Includes 4 black steering tube height spacers: 20mm, 15mm, 5mm, and 3mm for dialing in stack height
  • Pairs with the Warp 9 Front Fender Adapter for a complete fender mounting solution
  • Built for forks that don't already have a fender mount on the lower clamps

Stop re-tightening the same loose head bearings every ride and fix the actual problem once. Ships fast from the USA, straight to your door.

Frequently Asked Questions

What problem does this actually solve?

It stops the OEM star nut from walking up the steering tube under impact, which is the usual cause of head bearings that keep going loose no matter how often you tighten them.

Do I still need the separate fender adapter to mount a fender?

Yes — this stem lock adds the M5 threads needed for a fender mount, but you'll pair it with the Warp 9 Front Fender Adapter to actually bolt an OEM-style fender on.

Will this work with my fork if it already has a fender mount on the lower clamps?

This kit is built for forks WITHOUT an existing fender mount on the lower clamps. If yours already has one, you likely don't need this specific fender-threading feature, though the stem lock function itself still applies.
