The 44mm clincher is the all purpose carbon wheelset. No matter what type of riding you are doing, the 44mm depth with improved aerodynamic profile will be a great option for you. It's a great wheel set for climbing, descending, windy conditions, races, and even training. With the mid-depth aero rim height and improved design to handle the crosswinds these can be used even in very windy areas. With the low weight of the wheels they are a great climbing wheel set and on the opposite side of that climb the wider rim profile will make for great handling when flying down a descent.Rim depth - 44mm Rim width - 27mm Inner width - 19mm Rim weight - 465 grams


We have been working on our new tubeless rim bed profile for years, delivering a rim that can safely run tubeless tires as well as well as normal tube and tire. To read more about the Boyd tubeless difference, click here.Adding the Tubeless Kit: The tubeless kit above will include our new (blue) tubeless tape and tubeless valves pre-installed on the wheels! We will install two layers of the tubeless tape in the exact width you need for your wheels. We will also include and install two of our tubeless valves in the exact length needed for your wheels. Take the guess work out of converting to tubeless and let us do it for you. Note: you will still need a tubeless specific tire and sealant to run the wheels as a tubeless system.


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.


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.


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.


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.



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.


Free Skewers included Free Rim Strips included Free Onyx Carbon Brake Pads included*Weight limit - 220 pounds 20/24 - 250 pounds 24/28 *You do not need valve extenders if you are using an inner tube with a 60mm or longer valve.


  1. Hi

    Jumped on your Black Friday sale because I needed a Cross set of wheels.
    And I got a set of 44s 24/28 to replace my old 38s from 2010 with over 20,000 miles.
    The 44s hit all the marks
    Stiff , no wind up to speed
    Brake great in dry , too cold for wet
    They take a 28mm tire and no bounce or cornering weirdness at high speed.
    I estimate another 20,000 mile wheel set
    The only thing I did not like was
    The free wheel is crazy loud , but I do not free wheel much anyhow.
    And the wheels do not play well with other wheel set as far as having to reset your shifting when witching wheels out.
    Again for one of your great wheelsets

  2. Go road tubeless! These wheels are fast, light, and really smooth on any road surface. My info.- 148 lbs, KHS Flite 950 carbon road bike, 54cm, 44mm carbon clinchers, Schwalbe Pro 1 tubeless, Orange Seal tape, valves, and sealant (I set mine up for tubeless before Boyd’s Tickled Pink was available). I ride these wheels from 76 psi to 80 psi depending on the conditions. They are the smoothest, fastest wheels I have ever used (including racing Vittoria tubulars back in college!). Stiff (in my meaning- they don’t deflect laterally on hard efforts) and fast to spin up, they hold 20+ mph speeds very well. Crosswinds are the same for anyone riding carbons wider than 28mm: after a few rides, you get used to the minor behavior of the wheels in the wind. Then, crosswind behavior it is not a factor. The speed, smooth ride, and stiff response make these wheels the best for all-around performance. Tubeless is just icing on the cake. Yes, I still carry an inflator and a spare tube on rides!

  3. Excellent complement to my 28mm tires.
