AL 345 Trail / AM
We took what we learned designing some of the best carbon mountain bike wheels on the market, and set out to create a durable and affordable aluminum wheel without compromise. Enter, the Atomik AL345.
Designed to handle the abuse of modern trail and all-mountain riding, the AL345 is crafted from 6069 series aluminum for an optimal strength-to-weight ratio resulting in bombproof performance and reliability without the uphill penalty. Backed by a two-year limited warranty to the original owner, the AL345 is a feature-packed, performance driven, no compromises wheelset.
The AL345 features a low profile engineered to blend precise handling with a compliant ride. Both 27.5 and 29-inch versions feature a 34.5-millimeter outer diameter, and 30-millimeter inner diameter to provide an optimum profile and footprint on tires up to a 2.8-inch width.
The Atomik Carbon Upgrade Program – good for the life of the AL435 complete wheelset. If at any time the original owner chooses to upgrade to one of our carbon rim offerings, we will rebuild the wheel using your existing hubs—including new Sapim race spokes, brass nipples, all labor and return shipping—at no cost to the customer with the purchase of carbon rims.

Bead Lock
All Atomik Carbon rims utilize an angled bead lock to keep the tire bead positioned on the shelf when air is released from the tire and also adds a level of safety if a tire is leaking. This features allows you to refresh sealant without having the tire bead fall into the center of the rim, resulting in a tire that is more difficult to inflate and re-seat.
Hookless Design
The hookless wall thickness is a whopping 3.5mm and designed to help displace impact. The wall thickness is much greater than traditional hookless designs (as shown in the illustration above) and the additional strength provided by the thicker sidewall yields a rim that is light and extremely strong.
Impact Resistant Construction
Atomik Carbon rims feature a layer of composite material that increases the impact strength and helps distribute energy and shock from impacts to the rim (illustrated above) All rims use a blend of Toray 700 and 800 carbon fiber with the Toray 800, which is 25% stronger, used in high
impact areas.
