Ride a pair of Open Pros and you’ll understand why so many experienced riders swear by them. - Clincher

After a red nose, one of the most identifiable traits of a clown is his footwear. They're huge. So are Surly's Clown Shoe rims. At 100mm wide they greatly increase the tire footprint and give you more stability and float in loose terrain. The material between the spokes is drilled out to reduce weight and 64 spoke holes let you build them up centered or offset.

My Other Brother Darryl is a single-wall constructed, 80mm wide rim. 80mm wide rims give you a bigger footprint than that of narrower rims, which means more floatation and more traction. To initiate tubeless sequence, you just need a no-stretch rim strip and bead-to-bead tubeless rim tape. My Other Brother Darryl comes with either a 32 hole, symmetric wheel lacing spoke hole pattern or the tried and true 64 dual spoke hole pattern that allows for symmetric or offset wheelbuilds. It's got plenty of cutouts to keep the weight down and help your tires float through the squishiest of terrain. - Wheel Size: 26 - Hub Compatibility: 32h - ETRTO*: 559mm - Weight: 710g (Symmetric) 740g (Dual) - Color: Black or polished silver *Tire bead seat diameter.

The Ribcage has been one of the only rims to have true design breakthroughs in the last few years, since its introduction the competition has scrambled to catch up but still remain a poor copy, so if it doesnt say G-Sport on the rim, don't expect it to perform like a G-Sport rim. The Ribcage is a light weight rim that can take anything you throw at it. With the ribcage the spoke holes are re-enforced with patented ribs that support the sides of each spoke nipple and eliminate the possibility of nipple pull through under even the highest loads. The rim also features cross-over-spoke lacing, where each spoke goes from one side of the hub to the opposite side of the rim for an increased angle and therefore increased lateral strength. The outer walls are extra thick to protect against case dents, while the other walls are extra thin to keep it light. The entire design revolves around the use of a proprietary high strength aluminum alloy made specially for us in an on-site foundry . At 500 grams, the strength to weight ratio of the Ribcage cannot be matched. The 36mm width and 18mm height are also major factors in the design, spreading out the impacts and maximizing resistance to pinch puncturing. GSport offers rims in HARD anodized finishes rather than the decorative anodizing used by most companies. All of these advantages create the premier rim, but do effect the cost. TECHNICAL SPECIFICATIONS - Sizes: 20" Only - Drillings: 36 and 48 - Weight (Hard Anodised): 500g /17.6oz - Weight (Chrome Plate): 540g / 19oz - Width: 36mm ERD: 389

If the Ribcage is too rich for your blood, the Rollcage is its more affordable sibling. Using the same proven shape and cross-over-lacing to create a really strong wheel, but industry standard 6061-T6 alloy and no ribs drops the price considerably. While the Rollcage is the lesser expensive, it is still an excellent rim, with the same super tough sidewall and bead profile its the lightest rim we make at 450 grams. You will recognize the rims by their outer shape, but the Rollcage is actually 2mm narrower and easily identified by the groove in the middle of the inner wall. We offer rims in HARD anodized finishes rather than the decorative anodizing used by most companies. TECHNICAL SPECIFICATIONS - Sizes: 20" Only - Drillings: 36 and 48 - Weight (Hard Anodised): 450g / 15.9oz - Weight (Chrome Plate): 490g / 17.3oz - Width: 34mm ERD: 389mm

Someone said a few years ago that there was nothing new left to do with BMX rims, yet since then GSport has gone on to do quite a lot of new stuff, and here’s an example of the latest. At first glance the Birdcage looks like a fairly conventional “aero” style rim, but there is more to it than that. The first clue comes from the name; birds have hollow bones to save weight whilst retaining as much strength as possible, and the Birdcage rim has a hollow bead for the same reason. The rim’s hollow bead is still big and chunky to help reduce the chances of pinch puncturing or flat spotting the rim, but by creating a tiny hollow cavity inside it GSport can also keep the weight right down. The next innovation was to adapt their cross-lacing design to the narrow inner wall of the rim. They managed to squeeze a few extra millimeters of spoke offset out of the design to help increase lateral wheel strength, and by carefully tailoring the rim’s cross-section we managed to match all the angles to the nipple so that the walls of the rim section act like the ribs inside the Ribcage rim, which helps to support the spoke nipples as much as possible. Traditionally, the greatest flaw in “aero” rims has been the valve hole. “Aero” rims position a lot of very efficiently utilized mass in the base of the rim to support the spokes and give the rim good strength, then a huge hole is drilled through it for the valve stem and a massive weak-spot is created. With the Birdcage GSport has offset the valve hole so that this section can retain its strength. A handy side-effect of this is that fitting a pump is now more convenient. Aside from these original features, GSport spent a lot of time “sweating the small stuff”. They’ve ensured that the deep center allows for easy tire removal and fitting, and they've made sure that the sidewalls, while slimmed down, are still suitable for brake use. The end result is one of their most high tech rims to date. With a weight of just 408g (14.4oz) it outperforms most rims weighing 20-30% more, and the weight saving from the rotational mass of the wheel feels fantastic. TECHNICAL SPECIFICATIONS - Sizes: 20" Only - Drillings: 36 hole - Weight: 408g / 14.4oz - Width: 34mm ERD: 383mm
