Hunt Bike Wheels has released its latest gravel wheelset, the Limitless Gravel Adventure. It follows the same pattern as the existing Hunt 42 Limitless Gravel Disc wheelset but beefs up the spec to handle the high loads and torque typical of bikepacking and ultra-endurance rides while retaining the wide aero rim profile of the 42 Limitless wheelsets, which we rated 4 out of 5 stars when we reviewed it last year.
Typical of the best gravel wheelsets, there’s an aero rim profile. Hunt’s Limitless aero tech allows it to build a very wide wheel rim, in this case, 25mm internal, and 36mm external, while still maintaining a competitively low claimed weight of 1,642g. This is achieved by incorporating a low-density polymer in the rims, which is under half the density of carbon fibre and bonded to the carbon fibre outer layer.
It’s a design that it applies to its road bike wheelsets like the Hunt 48 Limitless UD Carbon, which we reviewed recently.
The construction method allows Hunt to build a 42mm deep U-shaped rim profile that’s optimised for aerodynamics when fitted with 38-42mm gravel tyres. Hunt claims up to 16.8 watts of aero gains over non-aero gravel wheelsets in its wind tunnel testing. Saying that over a 200-mile race, this could save between seven and nine minutes.
The brand says that the wheels are also very stable in gusty crosswinds, a property that we remarked on when testing the 42 Limitless Gravel Disc wheels, and also an advantage to the long-distance gravel rider.
There’s a hooked bead for maximum tyre compatibility when run both with tubes and tubeless, although Hunt provides tubeless tape and valves, as well as spare spokes with the wheels and there are axle adapters available if your gravel bike has non-standard spacing.
Beefed up spec
The adventure part of the deal starts with an increased spoke count: 24 front, 28 rear, as against the 42 Limitless Aero Gravel Disc’s 20/24 spokes. Both wheelsets use the same J-bend Pillar Wing aero spokes, but with brass nipples in the new wheelset to increase durability.
The hubs too have had an upgrade to handle the high torque loads typical when riding loaded. There’s a double floating ratchet freehub, as against the three-pawl design in the 42 Limitless Aero Gravel Disc wheels. The 40 tooth ratchet does result in an increase in the engagement angle to 9 degrees from the 42 Limitless’s 7.5 degrees…
