Psylo Gold RC 27.5in Boost Fork

What Our Gearhead® Experts Are Saying:

"I ran the Psylo Gold Isolator RC 27.5in Boost Fork back to back against forks at a higher spec and the gap was smaller than expected. The premium bushing package breaks away with almost no resistance through rough terrain, and the DebonAir spring combined with Bottomless Tokens gives you real tuning range without touching the internals."

The Psylo Gold Isolator RC 27.5in Boost Fork sits at the top of the Psylo platform, combining the 35mm aluminum chassis with RockShox's flow-focused Isolator RC damper for a trail fork that delivers genuine performance tuning at an accessible spec level. Designed for trail and eMTB use with a 130mm travel and 44mm offset, it suits modern trail geometry bikes running 27.5in wheels with up to 81mm tire clearance.

The Isolator RC damper offers three-position compression adjustment covering open, pedal, and firm modes, with externally adjustable rebound damping for precise traction control across varying terrain. The DebonAir air spring is positioned higher in the travel to maximize use of the full 130mm stroke, delivering a smooth, coil-like feel with Bottomless Token compatibility for riders who want to tune mid-stroke ramp-up without changing springs. Premium bushings offer a lower breakaway force than the standard Psylo platform, reducing friction and improving small-bump compliance through technical sections. Maxima Plush damping fluid and Dynamic Suspension Lube reduce internal friction and damper noise across the full service interval.

The 15x110mm Boost thru-axle interface pairs with the tapered steerer for compatibility with current trail frame standards, and post mount brake tabs support 180mm rotors. A RockShox short fender is included for riders running this fork in mixed or wet conditions.
