Carbon-Ti X-Wheel 44 laces GravelCarbon & SpeedCarbon tubeless wheels for all roads

Tips & Reviews

Carbon-Ti adds two new mid-depth aero carbon X-Wheel Road wheelsets to their lineup with new SpeedCarbon Disc 44 and GravelCarbon Disc 44. Both sharing the same 44mm deep, 23mm wide internal blunt-nosed aero rim profile, the SpeedCarbon wheels get a lighter build at just 1260g for the pair, while the GravelCarbon get extra reinforcement to handle more off-road abuse.

We know Italian manufacturer Carbon-Ti for their mixed material components like carbon-spidered brake rotors, wildly machined composite chainrings, and lightweight hubs. All made-in-Italy, Carbon-Ti also laces a limited selection of road & XC wheelsets in-house, too.

Now they’ve added two versatile carbon road & gravel X-Wheel Road wheelsets, which use their own light alloy X-Hubs laced into one of two different rims, both out of the same mold. 44mm deep x 29.5mm wide eternal x 23mm internal, with a “micro-hook” bead that Carbon-Ti says combines the stronger bead of a hookless rim and the added security of hooked tubeless rim.

First out of the mold is the Carbon-Ti X-Wheel SpeedCarbon Disc 44, which dictated the wider rim design to match wider modern road tires (Carbon-Ti recommends 28mm and wider tires) and provide a smoother airflow transition between rim & tire for improved aerodynamics / reduced drag. An asymmetric rim spoke bed is said to balance spoke tension without impacting aero performance.

The road version is built up with 24 triple-butted bladed Alpina Hyperlight stainless steel spokes and aluminum nipples. They have a wheelset weight of 1260g, and a 100kg limit (rider+bike).

The gravel and cyclocross-ready GravelCarbon Disc 44 version uses the same rim profile, simply reinforced with extra carbon in the rims to handle more rough off-road surfaces, and the additional resulting stresses & impact forces.

Both variants are made-in-Italy by Carbon-Ti and handmade to order, laced to Carbon-Ti’s own lightweight alloy straight-pull X-Hubs. That means they have a roughly 4-6 week lead time, but it also means there are some good customizable options. Buyers can pick either the Carbon-Ti X-Wheel SpeedCarbon Disc 44 or GravelCarbon Disc 44 for the same 1790€ price tag, including spare spokes but not tubeless tape or valves.
