Air fork, hydraulic brakes, and thru-axles push the woom OFF AIR 5 into real trail territory
What Our Gearhead® Experts Are Saying:
"The air fork is impressive, with compression and rebound you can adjust for a child’s weight, plus a lockout for climbs. It’s the kind of setup you usually only see on more advanced hardtails."
At the core of the OFF AIR 5 is a decision woom makes that most brands don't: every component was engineered for a growing rider, not borrowed from an adult bike. The RST air fork is tuned for lower body weights, with adjustable compression, rebound, and a lockout for climbs. Sealed thru-axles keep the contact patch precise on rough terrain. The flip-flop stem adds room to grow without buying a new bike.
Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
