MAYOR V4 Aluminum
This is not fake news: Fat bikes have evolved from 1-season freaks that were built for riders who couldn’t make it through snowy winters without a pedal. So we’ve changed with the times and updated our flagship Mayor to be a legit all-season bike. The best value in the fat bike category is now an excellent candidate for year-round trail campaigns.
To make good on this claim, these small but significant changes were made to V.4 of the Mayor:
Slacker head angle – 67 degrees
Steeper seat tube angle – 74 degrees
Sliding drop-outs and chainstay lengths of 450mm-465mm (sizes S to XL) allowing up to 100mm rims and 5.05” tires
Greater reach (on all sizes), and shorter and unique head tube lengths for each size, too
Internal dropper-post cable routing
The qualities that made your old Mayor great are still true:
Custom hydro-formed 6061 tubing and RSD carbon fork
Massive rear stays to guarantee lateral rigidity
197mm rear thru-axle and 150mm front spacing
Proven build with RaceFace cockpit and Turbine cinch cranks with direct-mount 28t ring
