The Diamondback Mason 29er hardtail mountain bike is built and designed for all-mountain versatility, delivering a solid, stable ride for those tackling aggressive lines.
Large 29er wheels roll over obstacles easier and faster thanks to more momentum and a decreased angle of attack; plus, you get more tire contact for enhanced traction
6061-T6 Weapons Grade Aluminum frame boasts an array of formed and butted-and-formed tubes along with a tapered head tube to deliver a strong, stiff and responsive ride
Slack 66.5° head tube angle offers stable, confidence-inspiring handling on aggressive trails; 16.77 in. long chainstays make it easier to get the front up over obstacles
Fox 34 Talas 29 CTD Air fork has a butted 1.5 in. tapered steerer, 34mm Easton aluminum stanchions, magnesium lowers and QR15 thru axle, all with 140mm of adjustable travel
Fork travel can be simply tuned between the 3 CTD settings (Climb, Trail, Descend); also has external rebound adjustment for easy tuning
RaceFace Respond single-ringed crankset with MRP chain guide is paired with 10-speed, 11-36t cassette for good all-around gearing; ISCG 05 tabs make an upgrade easy
SRAM X9 shifter guides the X9 Type 2 rear derailleur quickly and precisely through the 10 gears
Avid Elixir 5 hydraulic disc brakes deliver responsive braking thanks to a 200mm rotor up front and 180mm rotor in the back
