It’s not often that “affordable” and “carbon” appear in the same sentence, but our Control 29 Carbon wheelset was designed to change that. Utilizing many of the same techniques used in the development of the SL iteration of the Control 29, these wheels provide the lightweight XC performance you need at a more attainable price.

Creating a successful XC wheelset isn't as easy as you might think. Often times, keeping a wheel light, stiff, and strong requires an unlimited budget. So when we were asked to create a wheel that had low inertia and weight, but was also affordable, strong enough to take on rocks and roots, and wide enough to optimize traction and rolling resistance, we knew that we had our work cut out for us.

We started with the notion of keeping these wheels as close to their SL brethren as possible. And with this, we explored what made the SLs so awesome in the first place, and then we implemented nearly every aspect of them. Starting with the rim, we kept our renowned Zero Hook Bead that allows for continuous fiber layup across the sidewall and rim bed. We then paired it with a wide 25-millimeter internal profile that makes it resilient to impact and creates a tire profile that’s conducive to low rolling resistance and incredible traction.

On the trail, these technical traits translate to a wheelset that many XC riders have grown to love—quick accelerations on punchy climbs, swift stopping that lets you leave braking till the last second, and unprecedented reliability. Combine this with the easy to set up our 2Bliss Ready system and you have a reliable XC wheelset that’s as easy to climb on as it is to work on.

To go along with the rim, we made sure to keep the lightweight, reliable, and affordable features in mind when building the wheelset, so we took DT Swiss 350 Classic hubs (15x110mm thru-axle front / 12x148mm thru-axle rear) and hand-laced them with 28 DT Swiss Competition Race spokes. Finding hand-built wheels is becoming more and more difficult, but we're fully invested in the power of the human touch. When a wheel is machine-built, there are certain margins of error that are built into the system that result in inconsistencies. With a real person building your wheels, however, you're sure to get a wheelset that's free of imperfections.

Ask Jaroslav Kulhavý, and he'll tell you—every gram counts in cross country racing. But with XC tracks becoming more aggressive than ever, just being a flyweight wheel is no longer sufficient. Now, wheels need to be as tough and stiff as they are light, with all of the handling characteristics that seasoned XC riders have come to expect. These days, wheels need to be more like the new Control SL 29 with 148 rear spacing.

When our riders asked us for the ultimate cross country wheels, we knew that they were really asking for some pretty specific features. They had to be light in order to be low in the inertia and weight departments, strong enough to take on rocks and roots on a short-travel race bike, and wide enough so that the tire profile was optimized for both traction and rolling resistance—not an easy feat.

To check all of these design boxes, we started by looking at our Traverse SL rim to see if we could extract the wide-rim benefits while keeping the weight at, or below, the previous Control SL—the existing benchmark. Based on the width we knew was ideal for the desired ride characteristics, we tuned the rim shape to optimize the stiffness, weight, and ride quality of the system as a whole—too tall and the wheel rides too stiff, too shallow and the wheel is too flexy. Our engineers meticulously went through rim shape developments to find the perfect balance and optimal geometry, and after fine-tuning multiple layup iterations and schedules, we ended with a 25-millimeter internal width rim that's approximately the same weight as the previous Control SL.

Being able to add material and width (3mm to be exact), without a weight penalty makes for a stronger XC wheel, but we weren’t content settling with just an increase in strength. With our goal being the fastest race wheelset available, we took the new and old rims, paired them with a set of size 2.0 Fast Trak tires, and performed rolling resistance tests at both 20 and 30 PSI. The result? The new, wider rim tested faster at both pressures, confirming our line-wide hypothesis that wider is not only stronger, but also faster.

Keeping the Zero Bead Hook design, the new Control SL rim keeps all the sought-after features that come with this design—added impact resistance, easy tubeless tire installation, and a better tire seal on the rim. And with a lighter rim, you're also rewarded with extremely low inertia, that translates to faster accelerations for the punchy efforts required of XC racing. Focusing on the wheels as a system, we kept with our core design tenants of lightweight and durability, so we made sure not to skimp on the build. Each wheel is built by hand, and while this is somewhat of a lost art, we know that a real person can achieve qualities that a machine simply can’t. When hand-building, little discrepancies can be found that would otherwise be missed by a machine, so we took the refined 2Bliss Ready rim and matched it with our CNC-machined hubs with DT Swiss Competition Race spokes. The hub internals feature sealed bearings and DT Swiss 240 internals with a 54-tooth star ratchet in the rear, making for lightning fast engagement.

Finally, with the 110/148 variant, you receive all of the benefits that Boost spacing offers. By increasing the width of the front and rear hub flanges, and in turn, increasing frame and fork clearance and stiffness, you obtain a stiffer, stronger, and more durable system at a minor weight penalty.

If you’re in need of sub-1400-gram, race-ready wheelset that has handling and strength of a modern trail wheel, the Control SL 29 148 is the perfect choice.

When you think of lightweight XC wheels, aluminum probably doesn't come to mind. In reality, though, high-grade alloy wheels have all of the tremendous performance properties found in carbon, like light overall weight, durability, and resilience to impact. And when made with the right hands, they're perfect for competitive racers and everyday trail riders alike. The problem is that, while many carbon wheels can check these boxes with ease, most alloy wheels don't live up to these expectations. In the case of the Control 29 wheels, however, there’s finally an aluminum wheelset that's truly ready to race.

What sets the Control 29 wheels apart is that they share many of the same advanced technologies as our carbon version, the Control SL. They adopt the same rim shape with a 25-millimeter inner width, extensive on-trail testing, and our Zero Bead Hook technology.

Our Zero Bead Hook rim takes away the dated mountain wheel design known as a bead hook. This hook is the part of the rim that crests at the top, sitting several millimeters inward from the rim’s sidewall, and it catches the tire’s bead under its hook. We know this may not sound too bad, but the hook establishes a weak spot in the rim that's easily crushed or bent. Without a hook, a rim can be manufactured to much tighter tolerances and can be made lighter due to the hook not needing to be reinforced. For these wheels, this means that we're able to nearly equal the strength of carbon, while also making them lighter than many carbon wheels. More importantly, a Zero Bead Hook all but gets rid of the aforementioned weak spot in the rim that's plagued riders with flat spots and dents for decades. If you happen to be one of those riders that enjoys riding your four-inch travel XC bike like it’s a six-inch trail bike, you’re in luck.

Our objective of low weight and reliability, at an accessible price, also carries into the Control 29 build. We hand-build each rim to our alloy hubs, which feature DT Swiss internals at the rear and a design that allows for the same spoke lengths at both front and rear, via perfectly tensioned DT Swiss Revolution J-Bend spokes and Pro Lock nipples. We fully support the art of hand-building and do so with our wheels, knowing that real people can catch things that a machine simply cannot.

It’s not often that “affordable” and “carbon” appear in the same sentence, but our Control 29 Carbon wheelset was designed to change that. Using many of the same techniques used in the development of the SL iteration of the Control 29, these wheels provide the lightweight XC performance you need at a more attainable price.
