Sun Ringle Charger Expert Wheelset

Some of you who scour the internet for the latest and greatest have undoubtedly checked out the newly re-badged Sun Ringle website, which shows off the company's entire rim lineup along with a host of factory-built wheelsets. Sun Ringle has produced some new tubeless compatible rims using the licensed Stan's NoTube bead socket technology (BST). New for 2010 is the Charger wheelset, which is available in both Pro and Expert trim levels and is aimed at the all mountain and cross country market. I recently received a set of Sun Ringle Charger Experts for my cross country rig and, after tearing open the shipping box that they arrived in, got down to business.

Technical specifications-

The Charger Expert is designed as an all mountain wheelset, relying on a Sun Ringle designed rim with Stan's tubeless technology, laced with Wheelsmith spokes to SunRingle hubs. The Charger Expert wheelset weighed in at 1820g (820g front, 1000g rear), which is pretty much bang on Sun Ringle's claim. The 28mm wide rims are available in white or black and give 2.35" tires a nice profile when mounted, while the twenty-four spoke design shaves a little weight over conventional 32 spoke designs. The rear hub (135mm) spins on four sealed bearings and employs three pawls on a thirty tooth ratchet, netting the rider an engagement of twelve degrees. The front hub is available either as a 9mm quick release or in a 15mm / 20mm version for thru-axle forks. The Pro series hubs can interchange between all 3 configurations and are available with the newest 142/12mm rear spacing, while using the same rims as the Experts.

Tubeless Setup-

I've been using various tubeless systems for about 5 years now using both UST rims and Stan's strips. This Charger Expert wheelset was the easiest setup I've experienced to date. I mounted up some Maxxis 2.35 Minion DHF single ply tires, sprayed a bit of soapy water on the bead and pumped them up with a floor pump. No muss, no fuss. I then deflated them, squirted in the sealant and pumped them back up. The tires sealed up without issue, but were a bit low the next day. After shaking the sealant around the bead area again, re-inflating and heading out for a quick spin, they've held air fantastically ever since. Thorough instructions for using Stan's rims and sealant can be found on the NoTubes website.

Riding Impressions-

I've been riding these wheels for about two months on my XC hardtail, the graphics are attractive and they make for a good looking wheelset. I'm not exactly a lightweight and my line choice is generally questionable so I was a bit hesitant about riding 24 spoke wheels especially on an unforgiving hardtail. So far they've held up perfectly and there is no hint of flex. After the first few of rides I put them on the truing stand and checked the spoke tension only to find them perfectly true and felt as tight as the first day. I'll be putting some serious mileage on these wheels over the summer and have full confidence that they will hold up to the abuse just fine.

 They actually aren't 24 spoke ZTR Flows, and that's a common misconception that Sun Ringle is trying to resolve. The rims are exclusively a Sun Ringle design, using the Stan's No Tube beadlock design.

 Coves are really nice and good-looking but I'd rather not feel like a 13-year-old named my bike

 So take the stickers off and run it bare, you are buying a frame for how it rides and whether the makers support you when you damage it. Who cares about the name?

 you can do whatever you want, but when someone asks the name of your frame model you still have to say Handjob.

 The Charger Pros are even lighter at 1699 grams!! check them out on the site! I've been riding the older chargers on my Trance X for the past 2 years and havent needed to true them yet. I ride XC/AM and DH at Diablo on my trance ever once in a while and the wheels are bomb proof!

 The Cove names are an industry classic... few brands manage to keep their roots alive that long... mountain biking needs these traditions!

 not bad in terms of weight ratio to rim width and wheels purpose, not a fan of big flashy stickers though.
