SR SUNTOUR XCR Air LO 24
Big Performance. Small Package. Trail Ready.
The XCR Air LO 24 brings real cross-country performance to smaller riders without compromise. Lightweight, responsive, and packed with features typically reserved for full-size XC forks, it’s built to help young shredders and smaller-framed riders take on real trails with confidence.
Trail Tech, Sized Right
With a lightweight air spring system, the XCR Air LO 24 offers easy adjustability for a wide range of rider weights, providing more tunable support and comfort than traditional coil forks. Whether it's rolling singletrack or rocky paths, this fork delivers smooth, predictable performance.
Reliable Control for Every Ride
A built-in hydraulic lockout helps conserve energy on climbs and pavement, while the durable chassis is tough enough for years of trail abuse.

Customer Reviews
I made the initial purchase in late Mar 2025, and had the fork installed early May by my LBS. I quickly realized it was much too squishy, even after adding more oil, based on unanimous internet research results and videos. I contacted SR SUNTOUR service dept and, after a few days of back and forth on obligatory troubleshooting, they sent a new replacement fork, and even offered to remove the travel spacer for me (63-80). The service was responsive, easy to work with, and really great. I think this a great fork option for a young rider at this price point - I marked it down as my first one had issues with the internals holding air. But, I highly recommend the SUNTOUR service professionals and the overall value proposition of the product.
While not cheap, this is the best option to upgrade a 24” kids bike with a broken fork or no fork at all. I upgraded my son’s 24” Trek precaliber from a 45mm travel zoom fork that seized. I was worried that the geometry was going to get out of wack overforking the bike so bad it it raked it out and gave him some more pedal clearance. We adjusted the fork to 80mm during the install and it was a straightforward process. The lockout is progressive hydraulic so you do have compression dampening adjustment on the way to being locked out.
There are few options out there for a quality 24" fork, My Kids bike's factory fork started to get a lot of play so put this on. It is lighter and sturdier than the heavy spring fork that came on the bike. There seems to only be 2 name brand 24" forks out there and this is the less expensive option. The stiction is decent and it seems to hold pressure well. I debated buying one of the no names but just didn't trust them enough with my kid riding trails. Overall happy with the purchase.
