The Roval Control SL 29 wheelset has a winning pedigree, having been ridden to World Cup and Olympic wins under Specialized’s top cross-country racers.
The latest generation of this wheelset is wider, lighter and still more affordable than many of its competitors. It’s no slouch on the singletrack, either.

As we’ve seen over the past few seasons, cross-country tracks are getting more technical. Bikes are following suit and the new Roval Control SL 29 wheelset seeks to keep pace by increasing width and durability.
Roval claims the impact strength of the Control SL 29 rims has been increased by 10 percent through refinements in the carbon layup. Despite the increase in rim width, Roval also claims no increase in rim weight.
In addition to improvements in rim strength and width, these hand-built wheels are now laced with more robust 2.0/1.6/2.0 DT Swiss spokes, rather than the 2.0/1.5/2.5 spokes used on the previous version.
As for the weight savings? Much of that comes from the use of airtight plugs in the spoke holes, rather than tape, to seal the rims for tubeless use.
Roval Control SL 29 first impressions
I tested the Control SL 29 wheels at the same media camp as the CLX 50 road wheels in Santa Cruz, California.
For the sake of comparison, I rode these lightweight XC hoops back-to-back with the Roval Traverse SL wheelset, which is designed for trail and enduro use.
Two things stood out right away: first, the Traverse SL wheelset gave the test bike a more accurate feeling when speeding through rocky terrain — no surprise here, given the very different intended uses.
Second, while the heavy-duty TraverseSL hoops were more precise when launching into rock gardens, they were also more jarring than the Control SL 29 wheelset.
This was very easy to perceive on the Specialized Epic hardtail used for this test. This also provided a classic example of the importance of pairing the right wheels with the right frame for the right purpose.
Roval Control SL 29 early verdict
So yes, the Traverse SL is the stiffer of the two wheelsets, but is the Control SL 29 stiff enough for aggressive XC racing or trail riding? My early opinion is yes.
Many featherweight XC wheels let you know you’re riding them too hard through tight downhill switchbacks by flexing as you push through the apex or lead you toward the outside line. The Control SL 29 was appreciably precise in these scenarios.
Lastly, the drop in weight is good and the increased rim width is great, particularly for riders who prefer to run higher volume tires.
It’s a promising lightweight XC wheelset that can be pushed to trail duties.
