Part of the development on Mason Cycles’s new aluminum and titanium Bokeh Adventure Sport multi-surface Road Plus bikes was the advent of high quality fat and lightweight wheels and tires. To handle the wheel duties they collaborated once again with their Sussex, England neighbors at Hunt Bike Wheels to develop an affordable performance alloy wheelset. The resulting Mason x Hunt 650b AdventureSport disc wheels were specially designed for the recent breed of quick moving fat tire adventure bikes like the Bokeh or recent 3T Exploro, that can fit around 50mm wide, high volume slicks or some light duty knobbies, and Hunt rates them for road and light trail use. Take a closer look and see how to preorder them after the break…
The new 650b Adventure Sport Disc wheels feature a gravel road and trail ready 25mm wide external/20mm internal rim to provide support for tires like the new 47mm Horizon slicks or 2.0″ Ranger knobbies recently introduced by WTB. Going in either direction you can build the wheels up to add cushion and float to mostly hard surfaces or more traction for loose dirt road and trail riding.
The wheels are designed for the FarFast concept and stick with the same proven construction and tech as their previous Mason x Hunt 4 Season Disc wheels. That means tubeless ready setup, with rim tape and tubeless valves pre-installed. They even provide the option to set the wheels up and ship them with one or two tubeless tire options already installed with sealant to eliminate the hassle, which I personally think is an excellent service and is priced cheaper than you can buy the tires and sealant separately.
Tech wise the 6061 rims use an asymmetric disc and tubeless specific profile for even spoke tension that is 24mm deep. They are laced up with 28 triple butted round J-bend spokes and brass nipples for durability and serviceability. The wheels use the same alloy Centerlock 4Season Disc hubset set up for 12×100, 12x142mm thru-axles and include 15mm front adapters in the box. QR and 135mm t-a adapters are also available separately as spares to fit pretty much any bike. The hubs use an alloy Shimano cassette body with a steel insert, but a SRAM XD driver is also available, and feature Japanese EZO bearings.
The 650b wheelset weighs in at a claimed 1579g. Wheels get a matte black ano finish and laser etched graphics on both rim and hubs.
Hunt does a good job of paying attention to the details, and the result is a wheelset that will last you a long time and perform through the toughest weather conditions. They even offer a pretty solid 60 day ride & return testing warranty so you can be confident in your purchase and even have a separate crash replacement discount.
The wheels are available now for pre-order with a retail price of £400. To lock in a set for the earliest October delivery you need to pay a refundable £70 deposit to reserve your wheels.
