ENVE Composites M Series 60 Forty Carbon Mountain Bike 27.5” DT240 Wheelset sits in the sweetest of sweet spots. It’s the wheel quiver killer, as the diameter, 650b, sits between the small 26” and the massive 29”, and with the thinking that this wheel will do 60% descending, 40% ascending means it is designed to be at home up and down the mountain.
ENVE is proof that American design can be done in the United States. The 32mm deep, 23mm wide internal (29mm external) rims are light and strong. 1419g (for the 28-spoke, Centerlock offering) is light, but no less durable than the 32-spoke option. The rim is equally strong, just that a rougher, stronger rider might want more spokes to keep the wheels in line under hard efforts. The design itself is a marvel of simplicity, with a hookless bead that can hold any tire, even under the lowest pressures, without burping.
On the hub side of the spokes, they’ve only left room for the spoke to pass through, and that hole is molded rather than drilled. This results in a stronger wheel in two ways. One is that with no cutting or drilling to go from molded to finished product, there’s greater consistency from rim to rim, and they can deliver greater strength. The nipple itself sits between the interior and exterior walls, and a standard 3.2mm hex spoke key will take care of it.
ENVE uses DT Swiss 240 hubs rather than designing their own. Their focus is on the rim, and DT Swiss does an excellent job at building hubs. It also means it’s easier to find parts if you find yourself wearing hub components out. It’s a 15mm thru-axle front and 12x142mm rear. The hubs come with either Centerlock or six bolt rotor mounts. Centerlock is lighter and offers the flexibility to go six-bolt.
The connecting tissue is formed with DT Aerolite spokes. These wires are strong, light, and yes, aero. Even at off-road speeds, marginal gains can add up.
The wheels come with ENVE’s tubeless kit, of rim tape and valve. Of course, if you want to go tubed, all you need to do is simply remove the valve. They recommend tires 2.1-2.35” wide.
The ENVE M Series 60 Forty Carbon 27.5” Wheelset with DT Swiss 240 hubs does it all.
divergence from herd thinking on wheels is simple, yet fairly momentous. The front and rear wheels have different forces acting on them, and thus, should have different profiles.
The front wheel has a shallower profile, 35mm deep, and wider, 26mm, than the rear. This shape is to make handling in crosswinds easier, and steering light and predictable. The rear wheel is deeper, 45mm, and narrower, 24mm, both for slightly improved aerodynamics—as you don't steer with the rear. The wheels have been designed as a system: they weren't tested by themselves, but by putting them in frames and testing how they worked with different frame shapes. The wheels give a linear response, which makes them highly predictable. This might not seem like a big deal, unless you've been riding along and suddenly had a side wind gust push you off your line. Knowing that they handle predictably will make it easier to go into the red, with the confidence that you can put all your strength into driving rather than thinking about going in a straight line. They're still fast. Faster than some 60mm deep wheels out there. Smart shaping is the trick.
But ENVE is about more than shape. They're a carbon-fiber company. These hoops are strong. The spoke holes haven't been cut, they've been molded, so they're stronger. The spoke nipples are inside the rim, which contributes to both the overall strength of the wheel and better aerodynamics. The brake track is one that, when paired with the ENVE pads, results in rim temperatures that run lower than many alloy rims, which means that there won't be overheating, and the braking will be safe and predictable in both the dry and wet. As ENVE is based in the mountains of Utah, they take rim heating very seriously. They depend on their wheels braking well on their daily rides.
In addition to the brake pads, which are mandatory for the warranty, the wheels are delivered with titanium-shafted ENVE skewers, rim strips, and two sets of valve extenders.
We've been discussing rims, but these are wheelsets. As such, there are two hub options. One is DT Swiss 240 hubs, the other is Chris King R45 hubs with Ceramic bearings. Both are built 20/24 with DT Swiss Aerolite spokes, radial lacing in front, two cross in back. Both are available for Shimano/SRAM 10/11 and Campagnolo 9/10/11 cassettes. The DT Swiss weigh 1433g for the set, while the Chris King weigh 1418g.
ENVE stands firmly behind their products. Not only do they have a five-year warranty on their products, but they also have a lifetime crash replacement policy where they'll replace any ENVE product for 50% of MSRP, provided the customer has the paperwork to prove original ownership.
The ENVE SES 3.4 Clincher Wheelset are the wheels that work everywhere in every condition.
