e*thirteen has been on a bit of a tear in recent weeks. The brand released the Sidekick 2.0 hubs<\/a> last month, followed by radial tires<\/a> just a few weeks later. <\/p>\n

Adding to its announcements of new products, e*thirteen announces new Flux wheels to spin out those Sidekick 2.0 hubs. The wheels, available in both carbon and aluminum, cover a full range of riding styles, from lighter trail riding to downhill.\u00a0<\/p>\n

And e*thirteen also wanted to cover a wide range of price points, offering a wheelset for nearly every tier level. So, the result is a Sidekick-equipped anti-kickback wheelset for less than $600. Wow!<\/p>\n

e*thirteen moved away from a traditionally-shaped rim profile for the new Flux Wheels. Instead, they opted for a concave-shaped rim, providing extra vertical compliance. e*thirteen also claims that the new shape improves traction, reduces deflection, and better absorbs trail chatter. Testing of the new Flux Wheels shows a 33% increase in angular deflection compliance. Vertical deflection followed suit, with a 19% increase in compliance.<\/p>\n

Sounds great, right?<\/p>\n

As is becoming the norm, e*thirteen designed the Flux rims with a 30mm inner width. The wheels are also front- and rear-specific. Front rims feature maximum compliance and traction, while rear rims are designed for durability. <\/p>\n

e*thirteen achieves rim-specificity with different carbon layouts and rim thickness. And it seems the difference between the alloy rims is a welded or sleeved joint.<\/p>\n

What’s new?<\/h3>\n

There are four different Flux wheel categories:<\/p>\n

For lighter-duty trail, e*thirteen designed the Optimus<\/strong>. These wheels feature the Flux 33 (F) and Flux 43 (R) rims laced to Sidekick Pro SP hubs. These Optimus wheels are only offered at the Pro Carbon level.<\/p>\n

Stepping up to longer trail and all-mountain bikes, e*thirteen has the Sylvan<\/strong> wheels. These feature the Flux 43 and 54 rims (F\/R) and a Sidekick hub. All three build levels are offered: Aluminum, Pro Aluminum, and Pro Carbon. <\/p>\n

Pro-level builds feature the latest Sidekick Pro SP hub.<\/p>\n

Next are the Grappler wheels, both Enduro EN and DH. <\/p>\n

The Grappler EN<\/strong> also features all 3 build levels (Aluminum\u2013Pro Carbon), with Sidekick Pro SP hubs and Flux 54 and 55 rims (F\/R). <\/p>\n

Jumping to (or dropping in on?<\/em>) the Grappler DH<\/strong>, e*thirteen beefs them up a bit with the Flux 66 rims front and rear. Here, they only offer a Pro Aluminum and Pro Carbon build, both featuring the Sidekick Pro SP hub.<\/p>\n

The complete Flux lineup is also compatible with Class 1 e-bikes.<\/p>\n
