Stem Lock - W9 Fender Adapter Compatible - For forks without a fender mount on lower clamps. (Collective)

Fix loose head bearings for good with the Warp9 Stem Lock with Fender Mount Adapter — a precision-machined steering tube locking system designed for forks without a fender mount on the lower clamps.

The OEM star nut is notorious for walking up the steering tube under hard riding, causing head bearings to loosen over time. This kit eliminates that problem entirely with a full-length threaded rod that compresses the lower and upper triple clamps together, keeping your head bearings locked in place.

• Full-length threaded rod — runs the entire length of the steering tube, compressing lower to upper triple clamp for a secure, rattle-free fit
• Fender mount adapter — lower machined retaining nut includes two 5mm threaded holes so you can mount a fender even on forks without a lower clamp fender mount
• 4 steering tube height spacers included — 20mm, 15mm, 5mm, and 3mm sizes for dialing in your bar height
• CNC machined — precision fit, anodized finish available in multiple colors
• Direct replacement for the OEM star nut — no modifications required

Available in Black, Red, Blue, Magnesium, Gold, and Purple.
