Smaller Wheels, Bigger Tyres, More Opportunities


MASON x HUNT Collaboration number two! The HUNT 650B ADVENTURESPORT DISC wheelset is designed to ideally compliment the fast, fun and highly-versatile Bokeh Adventure Sport focused bikes which have a go anywhere attitude for those fun trail thrashes and bike-packing adventures whilst not ruling out those fast-far road days.


The opportunity to open up your riding comes from bikes 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 in the frame and fork while still running fast road groupsets, geo and components. That is exactly what Mason have created and with their incredible eye-for-detail thrown in!


We're delighted to have designed the wheels for the job. These wheels are also designed to perfectly compliment other gravel bikes with dual 650b/700c interchangeability. Oh, and If you are looking for a 700c wheelset for your drop bar adventure/go-anywhere bike then our HUNT 4SEASON GRAVEL DISC WHEELSET would be well worth a look.

We’ve designed a specific new rim profile for our new Gravel/Adventure wheels. Key features of this rim that make it great for the focused purpose of drop-bar adventure/gravel road riding are:


  • Wider 25mm external/20mm internal rim provides excellent ride handling and support for wider tyres and they work perfectly with up to 2.1” MTB tyres. 
  • The slightly deeper 24mm rim delivers excellent strength needed for the lower spoke counts and higher gear torques from road groupsets when compared to MTB setups. The extra depth also adds a very small extra margin of aero benefit but obviously only very marginal.
  • Asymmetric rim accommodates the front disc and rear cassette hub offsets and helps build an even stronger and more durable wheelset thanks to balanced spoke tensions.


Other key features that make the AdventureSport wheels ideal for dual 27.5"/700c bikes:


  • Fully adaptable axles, with the most common thru axles included with your wheels
  • Centre-lock hubs with 6 bolt adapters included so will work with Shimano road groupsets or SRAM 1x, plus SRAM now offer centre-lock rotors too.
  • Hard wearing laser etched graphics which also save extra grams.
  • Hunt 4Season Disc hubs with excellent bearing coverage and protection for long running life.
  • SRAM XD compatible. 'Dual 27.5/700c' bikes are ideal for 1x single front ring groupsets
  • Supplied with thru axle adapters included as pretty much all 'Dual 27.5/700c' bikes run thru axles only.
