CORE Bike: Halo adds Carbaura carbon gravel wheels and wider deep section road rims

The ISON Distribution team were at CORE Bike earlier this week showing off the latest carbon hoops from British brand Halo Wheels. Their roots are largely in the dirt, but in recent years Halo has branched out into the Road and Gravel disciplines. We got some info on the new Halo Carbaura XCD35 Carbon, a dedicated gravel wheelset weighing in at 1765g. Also on display are their new 21mm internal width deep section carbon road rims. Here’s what we know so far.

Halo Carbaura XCD35 Carbon Gravel Wheels

This is Halo’s first carbon wheelset dedicated to gravel riding. It borrows technology from the Carbaura Road line by adapting it for an internal rim width of 26mm that can accommodate a 50c tire (28c minimum), or even a 2.2″ MTB tire. As the name suggests, the rim depth is 35mm, with an external width of 30mm.

The 700c Carbaura Carbon Gravel Wheels are shipped pre-tapped, ready for a quick tubeless setup, though their hook rim design allows for the use of an inner tube should you need it in an emergency. The rim gets a standard symmetrical profile, as opposed to the asymmetrical rim bed you’ll see on Halo’s gravity-oriented axles which need to be a bit tougher.

The rims are related to Halo’s 120 POE GXC hub set which was developed 2-3 years ago for the Vapor GXC Tour aluminum gravel wheel set. There are 32 double butted J-bend spokes in the rear wheel and 28 in the front, available everywhere and therefore easy to find if you need to replace one.

The hubs are center lock only, designed to run a standard 12mm thru axle. Shimano HG and SRAM XDR freehub bodies are available. Claimed weight of 1765g is for Carbaura XCD35 Carbon wheels with a steel Shimano HG freehub body. The SRAM XDR version is said to be around 25g lighter.

The Halo Carbaura XCD35 Carbon wheelset will retail for £950. The maximum system weight is 110 kg.

Halo’s new 21mm deep section Carbaura carbon rims

Former Team Sky rider Russel Downing helped Halo develop the new range of deep section Carbaura Carbon rims for road cycling. The most notable update to these is the increase in internal rim width from 19mm to 21mm, allowing riders to run up to a 32c tire. The external width reaches 28 mm. These changes are in line with the larger tire clearances we see on modern road bike frames.

There are three rim depth options; 35mm, 50mm and 80mm, suitable for regular road riding, road racing and time trial or triathlon respectively. Sixteen stainless steel, reinforced, bladed spokes on the drive side and just eight spokes on the non-drive side help reduce weight; the weight of the 35 mm option is 1500 g.
