Roval’s new Terra gravel wheels use the widest rims on the market

New rough stuff wheelsets from Specialized’s hoop brand include Evo model, which will take 55mm tyres for extreme gravel grinding

Roval Terra CLX EVO 650b Gravel Wheel

Roval has announced its first-ever gravel-specific carbon wheels and claims that one set in the all-new Terra range — the Terra CLX Evo — boasts an internal width greater than any other ‘road’ wheel on the market.

The Terra CLX Evo’s internal wall-to-wall girth of 30mm is indeed impressive and, Roval says, this means you’ll be able to use tyres up to 55mm (2.1in) wide if your frame will allow.

It’s the 650b version that’ll take the fatter rubber with the 700c limited to ‘just’ 47mm. The CLX is designed to work best with 28 to 42mm wide tyres.

As well as claiming a width record, Roval also says that, at 1,296g (including rim tape and tubeless valves), the Terra CLX is the lightest gravel wheelset with a 25mm internal width on the market. The Terra CLX Evos tip the scales at a claimed 1,303g a set in 650b and 1,357g for the 700c version.

The Terras are designed to be ‘tubeless first’, and Roval is keen to highlight that it opted to forgo increasingly on-trend hookless rims for hooked rims. 

Although it makes manufacturing more complicated, Roval claims that it is “best practice to have a hook holding the tyre bead securely, given the wide differential in tyre size and potential for high pressures”.

Both the Terra CLX and CLX Evo models are built around Roval’s AFD hubs, which use DT Swiss internals. 

The standard rear hub uses DT Swiss’s EXP freehub and Shimano HG and SRAM XDR options are listed. The hubs are matched to DT Swiss Aerolite T-head spokes.

If you’re concerned about the durability of $2,500 carbon wheels, Roval reassures us that while designed for gravel use, the Terra’s pass its own mountain bike wheel standards. If that’s not enough for you, there’s also a lifetime warranty and Roval’s “***t Happens” no-fault crash replacement policy.
