The Story:

Perfect for your shred sled.

The 2019 Enduro class wheels features an updated, redesigned lower profile hoop, ready to run any size tire from a svelte 2.2, all the way up to a big 2.8. A 28 spoke-count for the front and rear keeps things light while not compromising strength. Its all built around our Mercury Disc hubs, using Sapim Race double-butted spokes, paired with Sapim brass nipples for a durable and reliable wheel that can be easily serviced for a long life and many seasons of shredding. The rims are laser welded for a seamless, balanced rim and they have a pronounced bead socket in addition to a flat rimbed that makes setting up tubeless a breeze. Our two cross lacing pattern gives it great lateral stiffness, while giving a small amount of compliance vertically, adding up to a sure-footed, comfortable, precise steering wheelset. Whether you are looking to update your bike with a lighter, stronger set of wheels or you want something that corners and climbs better than what you have, this is the wheelset for you.
