We dare you to find better wheels anywhere.


Starting today, you can order our carbon wheelsets for a limited early offer of $999.

Our ultra wide GT27 Carbon 650B (Gravel | Trail | 27mm internal) and aero-wide RCG44 Carbon 700C (Road | Cyclocross | Gravel | 44 depth) are designed for serious enthusiasts seeking strong, versatile, responsive wheels that will last for years. We've built them to a mechanic's discerning standard, with high-end DT350 hubs, 24 lightweight bladed straight-pull spokes, and wide tubeless carbon rims for outstanding handling.

Let's be honest: wheels of this caliber usually go for double or even triple the cost. We created them as an act of rebellion. And we think they're some of the best you'll find anywhere.

Best of all, our OB1 bike comes with your choice of either wheelset, meaning you can get a complete high-end carbon bike for the same price you'd pay elsewhere for just a wheelset. Sweet.

All wheelsets are hand-built and digitally checked for a lifetime of trouble-free use. The first orders begin shipping in October, so grab yours today to reserve your spot at this limited early offer.

  • Built for gravel grinding, singletrack shredding, and bikepacking trips, our GT27 Carbon 650Bs offer MTB levels of strength, tire stability, and durability in a race-ready 1495g package. Unlike skinnier rims, their 27.3mm internal width and hookless, tubeless design provide a broad base of support for running 45-61mm tires at low pressures for added traction, comfort, and control without the squirm.
  • Built for road, dirt, and touring adventures, our RCG44 Carbon 700Cs offer speed, strength, and durability in an aerodynamic 44mm, 1590g package. Featuring a mid-hook tubeless design along with 30mm external and 22mm internal widths, they transition smoothly with 28-30mm slicks for speed on the road while providing a stable base of support for dirt tires up to 45mm.
  • All wheelsets feature carbon rims with offset angled drilling and reinforced nipple beds for strength, the venerated DT350 hubset from DT Swiss for reliability, and 24 cold-forged bladed straight-pull spokes per wheel (all of a single length) with exposed brass nipples for durability and serviceability.
  • These wheelsets also come as standard equipment on the THESIS OB1 bike, where they can be swapped in under two minutes for the ultimate one bike for every road.

To sum it all up: these are some of the highest performing, longest-lasting, and most versatile wheels in the industry. We applied the same obsessive, evidence-driven approach to spec that we used throughout the OB1 bikeAnd we're selling them for a limited early offer of $999. Yep.

Our wheelsets begin shipping this October. Grab yours today to be part of the first shipment.
