THE SECOND IN A LINE OF MASON X HUNT COLLABORATIVE EFFORTS. THE GO-TO 650B/27.5" WHEELS FOR YOUR GRAVEL/BIKEPACKING RIG
19 Deep | 29 Wide Ext | 25 Wide Int | 1594g
The Purpose
The second MASON x HUNT collaboration, bringing go-anywhere capabilities to bikes like the fast, fun and highly-versatile Bokeh. 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 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" tire, providing an almost identical external tire diameter to a normal road sized 700c wheel with a 33mm tire, leaving the bike geo unchanged. What was needed was a bike that could accommodate the extra tire 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. Oh, and if you are looking for a 700c wheelset for your drop bar adventure/go-anywhere bike, then our 4 SEASON GRAVEL DISC would be well worth a look.

Warranty, HUNT Rolling Road Tests & Weight Limits
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. 253lbs 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 220lbs then an experienced bike mechanic should check the wheel regularly and it is advisable to use minimum 30mm tires at max 70psi as this will reduce the fatigue on the wheelset.

We carry full spares at very reasonable prices and offer complete support.
