With a unique shape and ride-tune, the AM30 balances compliance and vibration damping for all-day comfort, while retaining quick cornering, acceleration, and gravity-rated strength. Offset spoke holes balance spoke tensions to help preserve the wheels - quickness and the spoke's integrity despite the rim''s additional compliance.
- 30mm internal rim width supports 2.3 - 2.6" tires
- Asymmetric spoke holes for more balanced spoke tensions
- Molded conical seats allow the nipples and spokes to articulate, preventing premature fatigue and failure
- Molded Spoke Holes for more reliable wheel builds
- Wide Hookless Bead dissipates impact energy preventing the rim from slicing the tire

There are two attributes to the AM30 rim (and all ENVE rims) that set it apart from all the competition. First is the nipple beds. They are not drilled but are formed during the manufacturing process. The thickness of the carbon can be less there than other rims for that reason. That has two benefits – less mass and less obstruction of the nipple. The first goes without saying. Less obstruction means that the rim does not interfere with the spoke angle and there is less stress on the end of the spoke which means a lot less likelihood of spoke failure at the first thread. That is by far the most likely part of any spoke to break. So, ENVE rims make a much more durable wheel. The second attribute that sets them apart from all other rims is a wider shoulder to reduce the likelihood of pinch flatting the tire. The rim shoulder design of the AM30 uses this fact to create a rim where the strength is in the shoulders and so reduces mass in other parts of the rim. I believe ENVE claims it is a 50% less likelihood of getting a pinch flat with these rims than conventional rim designs. I hate flats, so this is huge for me. The AM30 rim is a little heavier than other rims in its class, but that assurance is well worth the extra mass.
