Overview
The Purpose
The new breed of Adventure Sport focused bikes have the ability and attitude for those fun trail thrashes and bike-packing adventures, whilst not compromising anything for fast-far road days.
The opportunity to open up your riding comes from bikes like the Cairn E-Adventure which have geometry designed to ride excellently with both 700c or 27.5" (650b) wheels. This combination works thanks to the extra volume in a 2" x 27.5" tyre, providing an almost identical external tyre diameter to a normal road sized 700c wheel with a 33mm tyre, leaving the bike geo unchanged. What was needed was a bike that could accommodate the extra tyre width, while still running road groupsets, geo and components. That is exactly what Mason have created, and perfected with their incredible eye-for-detail.
We’re delighted to have designed the wheels for the job. These wheels will perfectly compliment other gravel bikes with dual 650b/700c compatibility too.

- Tyres Info
- Maximum tyre pressure for this rim is 120psi when used with an inner tube and 100psi when running the wheel set-up tubeless. 100 psi is more than enough for any rider on road. Click here to listen to a podcast exploring the science of why lower pressures were found to be faster by pro teams.

The Details
Rims
Strong and light 6066-T6 (+34% tensile strength vs 6061-T6) heat-treated rim features an asymmetric shape which is inverted from front to rear to provide balanced higher spoke tensions meaning your spokes stay tight for longer. The profile is disc-specific, allowing higher-strength to weight as no reinforcement is required for a braking surface. The extra wide rim at 29mm (25mm int) creates a great tyre profile with wider 35c+ tyres, giving excellent grip and lower rolling resistance.
Nipples
To accompany these high-end spokes we selected brass nipples for our Hunt 4Season wheels. Brass is strong and corrosion resistant plus it has self-lubricating properties to prevent issues that can arise from grit salt on the winter roads corroding the fine threads in alloy nipples. As well as the standard square body we chose nipples with a hex head so you can achieve precise tensioning.
Bearings
Bearings are the heart of any wheel and investing in them makes huge sense so we went to Japanese bearing experts EZO and invested extra to spec their high-grade precision sealed cartridge bearings in our full range.
Freehub Body
Durability is a theme for HUNT, as time and money you spend fixing is time and money you cannot spend riding or upgrading your bikes. This is especially important for a 4 Season bike you use regularly in harsh conditions. As a result, the freehub features our H_CERAMIK coating to provide excellent durability against cassette sprocket damage often seen on standard alloy freehub bodies.
Rim Bed
H_LOCK tubeless-ready rim bed profile. H_LOCK is our tubeless-ready rim bed profile, with up-kicks to the shoulders of the tubeless steps. This helps to create a great rim-well seal for first installation and easy sealing of tubeless tyres. The H_LOCK profile also locks the beads in place more securely once seated. This is especially important when running lower pressures off road.
Spokes
We chose the top-of-the-range Pillar Spoke Re-enforcement PSR XTRA models. These butted blade aero spokes are lighter and provide a greater degree of elasticity to maintain tensions and add fatigue resistance. These PSR J-bend spokes feature the 2.2 width at the spoke head providing more material in this high stress area. The nipples come with a square head so you can achieve precise tensioning. Combining these components well is key which is why all Hunt wheels are hand-built.
Adaptability
Our wheels are seriously future-proof. We can adapt your wheels to any current axle standard on the market, you just need to let us know what are your requirements by filling in the simple form on the confirmation page after checkout. As Shimano hydraulic brakes are appearing on many new bikes, we wanted riders to have the option so we went even more adaptable with centre-lock hubs and 6 bolt adaptors included.
Tyres
At HUNT, we enjoy the puncture resistance and grip benefits of tubeless on our every-day rides so we wanted to allow our customers the same option. Of course, all of our tubeless-ready wheels are designed to work perfectly with clincher tyres and inner tubes too.
Weight
The consequence of the fanatic attention to detail is incredible durability and a resulting low 1594g gram wheelset weight. Acceleration and climbing are massively improved over many of the stock wheels supplied on road/gravel/CX disc brake bikes.

Warranty & Weight Limit
A full 3 years from purchase date warranty is offered to the original purchaser only on all Hunt bike wheels against material or workmanship defects, please click here to read full details.
All HUNT wheels models have to pass our harsh cobbled-rolling-road tests for rider weight limits, please see here for more details. 115kgs is the upper recommended rider weight limit for these wheels. Please include the weight of any luggage in your total rider weight when choosing the correct wheels. If a rider is over 100Kgs then an experienced bike mechanic should check the wheel regularly and it is advisable to use tyres at max 90psi as this will reduce the fatigue on the wheelset. We are cyclists ourselves and do of course go above and beyond to offer excellent service if you ever do experience any issues. We carry full spares at very reasonable prices and offer complete support.
60 Day Ride & Return Period. We are certain you'll be impressed by the acceleration, low-weight, speed and durability of our wheels. We are cyclists and as such strive to offer class leading service and support. Buy with confidence, if for any reason you wish to return the wheels for a full refund of your order you can do so up to a full 60 days after you receive them whether they have been ridden or not. Please note we cannot offer refunds on wheels that have suffered from crash damage but do offer a crash replacement discount.
