RIMS

The 90mm tubular is an ideal wheel for events like time trial or triathlon where aerodynamics are most important. Ever do a time trial, go as hard as you could go, and lose to somebody by a few seconds? Now you can do something about that with our most aerodynamic wheel ever! Since the 90mm is such a deep wheel it can be susceptible to heavy crosswinds although the design of the rim shape really makes crosswind handling better than wheels much shallower. A 23mm tire will handle in crosswinds much better than a 25mm tire. For events like longer distance triathlons, pairing a rear 90mm with a front 60mm can be the perfect set up!

The 90mm rim is 25mm wide. This is still a nice wide rim profile, but not quite as wide as some of the other carbons or alloys. Chances are you are not running 28mm tires or larger gravel tires on the 90mm depth so we could optimize it for that 23/25mm tire set up.

Rim depth - 90mm
Rim width - 25mm
Rim weight - 635 grams

 

TUBULAR

It's lighter, the tires are nicer, you flat less. There's a reason why pros trust tubular tires for all their races. Sure you have to glue on a tire, but if you are looking for the advantage of an ultra light weight set of wheels, go with the advantage of a tubular tire. Whether it's a mountain top finish, Paris Roubaix, or a cross race, the people on the top step are doing it on tubular tires.

 

 

TEXTURED BRAKE TRACK

Braking is not that important. . . until it is! One of the things people have fear in regards to carbon is the braking performance, especially in wet conditions. Carbon braking performance has always lagged behind aluminum in terms of pure stopping power. With the new brake track on these rims, featuring a slight textured surface, braking is better than ever. Feel confident that no matter what speed, terrain, or weather condition when you need to come to a stop you will.

HIGH TEMPERATURE RESINS

The resins on the new carbon wheels can take the mountains! Countless hours of testing and resin formulas have gone into making a rim that can be ridden in any terrain. . .with any carbon specific brake pad. Don't worry anymore about if you have the right brake pads for the wheels. Wheels have been testing in a lab environment on a dyno machine, and personally in the mountains of South Carolina on hot summer days. The real world testing of the resin capabilities comes in the form of slow speed descending on Greenville's Paris Mountain. On a 35C degree day, we are going to the very top of Paris Mountain and riding just the front brake the entire way down the mountain. It ends up taking about 7.5 minutes to get to the bottom, all while dragging the front brake. It's the true test of braking way beyond what anybody would do while riding. . . .and we do it again, and again.

PRIME ROAD HUBS

In part of making a complete wheel system, we wanted to have the highest quality hubs come standard on the wheels. We have a CNC factory produce the hubs for us to our specification to ensure you will have the stiffest, most stable, and best engaging hubs on the market.
Hubs can be one of the best ways to increase the stiffness of the wheels. If you think of a wheel as a triangle instead of a circle, the spokes have a base at the hub and come to a point at the rim. By increasing the base of this triangle you are making for a sturdier object, which translates directly to a stiffer wheel. Our hubs have some of the widest flange spacing on the market, which combined with the strength of the rims, help to make for an incredibly well responding and stiff wheelset.
Hub stability is something that is often overlooked, but is felt immediately when standing (such as when sprinting or climbing). To accomplish higher stability the bearings were also moved out as far as possible on the axle. Many hubs have a long end cap on the non-drive side with the bearing quite far from the edge of the hub. By supporting the non-drive side bearing and moving it out to the edge of the axle, the wheel stability is greatly increased.

SPOKES & NIPPLES

We feature Sapim CX Ray spokes and Sapim brass nipples on all carbon builds. Spokes are laced radially on the front and double crossed on both sides of the rear wheel for a stronger build and much better transfer of torque. All spokes and nipples are black.

SPOKE COUNT

We offer two spoke counts on all of our wheel sets. This is because not everybody has the same demands in a wheel set and to say that one wheel build will work for everybody just isn’t true. A 120 pound female triathlete is going to have much different demands in a wheel compared to a 200 pound masters crit racer who wants to use the wheels for everyday training and racing. So we offer the builds in options that will maximize both durability and performance. Going with the higher spoke count only adds about 40 grams to the weight of the wheels (less than half the weight of an empty water bottle), but will make for stronger, stiffer, and more durable wheels. If you are a larger, more powerful rider, and planning on using the wheels for years to come, you will want that added durability.
