With single chainring applications growing in popularity, for good reason, the Composites M Series 60 Forty Carbon Mountain Bike 29” DT240 Wheelset also comes with a SRAM XX1 cassette body so you can take advantage of eleven cogs and the tiny ten-tooth cog for your big gear.
The XX1 body is the sole change between the 60/40 DT Swiss 29 Wheelset and this. There you have standard Shimano splines for the cassette body.
ENVE designed the 60/40 as the wheel quiver killer. The thinking is that this wheel will do 60% descending, 40% ascending. At 428g per rim, you’ve got a hoop that climbs with the best, but still designed to be at home up and down the mountain. Likewise, with the XX1 driver, you’ll have a huge range of gears to choose from.
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. 1527g (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.
The ENVE M Series 60 Forty Carbon 29” Wheelset with DT Swiss 240 hubs and an XX1 cassette body tugs you uphill and protects you going down.
