Mark :

Purchased the 29 AM rims & built on existing hubs. Noticeable stiffness and smoother ride compared to Arch EX rims. Tires are definitely more voluminous with this rim. No way a tire is coming off these rims with the hookless bead and the diameter of the rim. Tires (Maxxis 2.4) go on easy but once filled with air, they pop in place. Only compliant is a tire is tough to break the away from the rim once the tire is filled with air, but once you break the bead into the middle rim channel, the tires comes off easily. Great rim so far but only have a 300-400 miles on them. I weigh 165 lbs. and run 22/25 psi on 2.4/2.25 tires(front/rear) on full suspension bike.

Hello Mark, Thanks for your support. We are so happy you are enjoying your new rims. It would be great to see a picture of them on your bike! The center channel design is for mounting tire and taking off tire. The channel is deeper, while you mount tire, the tire has to be seated on the channel first. After pumping the air, the air pressure will put the tire go to the bead seat area. If you like to take off the tire, you have to take the air out first. Then remove the tire to the center channel first, it will be easier to take off. It is tubeless design. Happy riding! Light-bicycle
