Founded in 2012, Derby Rims was one of the first manufacturers to bring ultra wide rims to the market. In addition to being at the forefront of the wider is better trend, their product was unique because it was carbon, and affordable.
At Sea Otter this year, they were showcasing a new ultra wide 29er rim that should appeal to both ultra wide and mid fat loving crowd.
The new rims have a 45mm exterior and 39mm inner width and will be available in both XC and AM rated versions around late May.
All of the 2015 production rims will feature angled spoke holes, which will better align the spokes with hub flanges, and will decrease the amount of spoke bend required when building with wider flanged hubs.
By reinforcing the carbon rim wall to ad a drain hole, water can easily evaporate.
A new feature for this new rim set is a water drain hole. This patent pending features allow water which enters through the spoke holes during a ride or after washing your bike to drain. This is critical for weight weenies, because Derby has found that water accumulation in the rims often ads as much as 50-100 g of weight.
The production XC rim will weigh between 500-520 g, and the AM version will probably weigh 30 g more. Retail is currently set at $420 a rim. To learn more, visit the Derby website here.
