Looking for quick engagement, solid build and easy axle and cassette swaps? The new Boyd Tripel rear mountain bike hub has all that, and they say it’s able to do so with very light drag. Oh, and it’s affordable, too, at just $175 for the rear and $100 for a matching front hub. The pair weighs in at a reasonable 440g, and will be built into two different wheelsets.
Check it out, along with the new 55mm deep aero disc brake wheels in this video, then scroll on for more specs and photos…

Inside the Boyd Tripel MTB hubs
The Tripel uses a 102-tooth drive ring inside that’s engaged by all six pawls at once. Each pawl has three teeth, giving you a very solid 18 points of contact to drive the hub forward. The math adds up to a snappy 3.5º engagement. That puts it close to the ever-so-slightly quicker Industry Nine Torch hubs, but Boyd’s has all six pawls connected rather than using an alternating engagement.
The shell is forged 6061 alloy with a strengthened alloy axle and your choice of XD or Shimano freehub bodies. They’re offered in 28 hole front, 32 hole rear only, designed for Centerlock rotors. Complete wheels come with either their alloy Kanuga rims ($700) or carbon Ridgeline ($1,650) rims.
Boyd 55 Disc Road carbon aero rims
Designed specifically for disc brake road bikes, the new Boyd 55 Disc Road rims use a lighter layup thanks to not needing a brake track. And the shape is new, as is the depth for them, all designed to maximize the performance for disc brakes. Like all of their wheels, you can order them Ready to Ride, too, where they’ll pre-install a cassette, tires and set them up tubeless for you.
The rims are made for today’s larger volume 700×25-32mm tires and measure 22mm wide inside, 29mm externally, and 55mm deep. The spoke holes are drilled at an angle to send the spokes straight to the hub flanges so they’re not subject to undue stresses, and the profile is slightly asymmetric (2.9mm offset) to balance out the spoke tension. The rim itself will be available in about a month, available on existing hubs for a wheelset around 1,700g. But the wheel as shown here will come later in the year…(watch the video).
