Sun Ringle A.D.D. Wheelset Review
Jumping Flea Hubs:
The A.D.D. wheelset uses Sun Ringle’s Jumping Flea hubs. They’re 32 hole disc hubs and are pretty light. They help keep the overall wheelset weight low. They’re only available in 20mm for the front with 12mm x 150mm or 12mm x 135mm for the rear.

The front hub is pretty standard in terms of conventional 20mm front hubs and worked well. It rolls on two sealed cartridge bearings and was solid the entire time. Sun Ringle claims it weighs 198g.
The rear hub is available in 12 x 150mm or 12 x 135mm. This means if you’re putting these wheels on a dirt jumper or trail bike, you’ll more than likely have to get a different solid thru axle for the rear since dirt jumpers and trail bikes usually don’t have 12mm dropouts. You’ll probably have to purchase a 12mm to 10mm thru axle to make it work if you have 10mm dropouts. Under operation our hub was pretty silent as the hub’s engagement was quiet and not like the typical Ringle Abbah hub if you’re used to a loud hub. Thankfully, the Jumping Fea doesn’t use the same loose non-drive side spacer that the Abbah does, which makes installing the rear wheel so much easier and is much improved. Sun Ringle claims the rear hub weighs 330g.

The rear hub uses 3 cartridge sealed bearings and one needle bearing to ensure it rolls smooth. The rear hub is easy to take apart and service as well. The rear hub has 24 points of engagement which isn’t a lot in tight or quick maneuvers but seems to be the minimum these days in hubs. The hub engages with a 3 pawl/spring setup. It’s not the most durable setup but is very easy to maintain and service should you need to. The rear hub felt loose in terms of engagement and each click isn’t as solid as we like.

The rear hub is also mated to an aluminum freehub body so it can get notched by loose cogs. The damage on the aluminum cassette body is pretty standard across the board as any aluminum freehub body will do the same thing. Functionally it still works just fine it just looks bad.

Improvements
It would be nice to have a higher engaging rear hub as well as a more solid engagement in the rear hub. A steel/titanium freehub body option would be a nice aftermarket or upgrade option to keep it from getting notches.
