Mayor V4 Titanium

(Some components in these photos may differ from the spec sheets. Please refer to the spec sheets below for accuracy)

Our incumbent Mayor has been significantly redesigned for its next campaign. The best value in the category just got better. Rear stays have been massively beefed-up using a new Titanium Custom Yoke design with an engraved RSD logo to increase lateral rigidity and handle the loads that you’ll be applying in a full term of fat fun.

But with the same proven build as the V2/V3, bolstered by RaceFace Cinch cranks and direct-mount 28T ring, and DT Swiss 80mm BR2250 wheels, all rolling on massive Maxxis Minion 4.8” tires, we don’t think there’s anything you’ll need to change on the V4 to make one successful run after another.

Changes include:
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
