Designed for trail and mountain terrain, these aluminum rims improve upon the previous model with a 24% width increase with a minimal weight increase. Meant to improve stability on the ride, these changes make for a softer feeling ride that allows you to ride over rocks and bumpy trails with fewer shocks and jolts. These rims come in sizes 26", 27.5", and 29" and are compatible with tires between 2.25" and 2.5" wide.

Many of the reviews surrounding this product praise the fact that the rims do their job without being extremely noticeable. Pinkbike describes that the rims "have a softer, more forgiving feel to them, but without the vague sensation that a lighter weight, skinnier set of rims can be guilty of having." After reading several user reviews, it seems like it's easy to slap these rims on and forget about them, which isn't necessarily a bad thing. If you're looking for rims that impress you on a regular basis, these might not be the ones for you. These rims do their job, and do them well, without you having to worry about them during a hard ride on rough terrain.
If you're in the market for sturdy and reliable rims that don't have the pricetag of comparable carbon rims, the Arch MK3 rim will serve you well on the trail for plenty of tough rides.
