Like the completely revised Black Flag wheels (we reviewed them here), Sun-Ringle’s new A.D.D. tubeless downhill wheels license Stan’s NoTubes rim technology for quick, easy tubeless tire seating.
While the license limits them to using the rim tech on complete wheels only, Sun-Ringle took the overall rim design a step further by adding eyelets at the spoke nipple holes to allow them to run higher tension and build up a stronger, more durable rim and wheel.
Full specs and photos after the break…
The A.D.D. Pro wheelset is built on Jumping Flea-like hubs with direct pull spokes that are only available on this wheel set. Quick specs are:
- 1995g / set
- 12×150 or 12×135 rear
- 20mm and 15mm frot adaptable hub
- Rim width 30mm
- Expert series will be available, too, with a heavier hub but same Stan’s rim.
- 28 spoke front and rear
- Wheelsmith DB spokes
- $649 Pro / $499 Expert
- Available in July
- 1 year Mfr’s defects warranty
I also learned that Hayes Bicycle Group (they own Sun-Ringle) manufactures these in their Chinese factory, and they make Stan’s rims, too.
For a component that’s meant to take some serious abuse and is often replaced or completely rebuilt once or more per season, these look to be pretty solid and, at just $650/set, a steal. In fact, most of Sun-Ringle’s wheelsets are extremely competitively priced and tough to beat on weight and quality for the money.
