Adjustable damping settings let you dial in compression and rebound to your weight and terrain — a meaningful upgrade over fixed-rate stock forks.
FastAce Red Cap Fork: Suspension Anatomy
Direct OEM-grade replacement with the factory steerer and axle dimensions. Adjustable damping is the key upgrade over older Talaria stock forks — riders typically notice the difference on rocky single-track and tabletop landings within the first few rides. Fitment runs across the main Talaria Sting platform, with model-specific notes below.

Install Notes
Difficulty: Advanced. Full front-end disassembly: bars off, brake line clip released, wheel removed, old fork unbolted from yokes. Tools: torque wrench, hex key set, fork-cap tool. Time: 90-120 minutes. After fit, set damping clickers to mid-range and adjust based on first ride — most riders end up between 8-14 clicks of compression, 6-10 clicks of rebound depending on weight.
Frequently Asked
How does the Red Cap compare to the stock Sting fork?
The stock Sting fork is fixed-damping. The Red Cap adds external compression and rebound clickers, which let riders tune the fork to their weight and the terrain. Most riders see meaningful traction and comfort gains on rocky or jumpy trails.
Will the Red Cap fit my Sting MX5 Pro?
No — the MX5 Pro uses Talaria’s own adjustable air + dual spring fork with 220 mm of travel. The Red Cap is for the earlier Sting chassis (TL3000-TL50) only.
How do I set up the compression and rebound damping?
Start at the manufacturer mid-point (count clicks from fully closed). Adjust 2-3 clicks softer on rocky terrain, 2-3 clicks firmer for jumps. Re-test after each adjustment; small changes make noticeable differences.
Trust Signals & Warranty
FastAce backs the Red Cap fork against manufacturing defects per their standard suspension warranty. Talaria USA covers a 30-day return window on unmodified parts and ships from our US warehouse in 2-4 business days.
