Tired of the drawbacks of traditional XC-oriented 29ers, Diamondback set out to build a 29er that could handle a little more than just races. Featuring a slack and low-slung geometry, the Mason hardtail is designed for those who don’t mind a stiff climb and love shredding trail. 29” wheels provide excellent momentum and angle of attack for getting through tricky rock sections while SRAM/Race Face components ensure smooth and reliable operation under the toughest of conditions.

The Mason features an All Mountain 6061-T6 Weapons Grade Aluminum frame with a formed top tube, a formed and butted down tube, a tapered head tube, ISCG 05 tabs and a 142x12mm Maxle drop out. A 140mm travel Fox 34 TALAS 29 CTD air fork features external rebound, a butted alloy 1.5” Tapered steerer, 34mm Easton aluminum stanchions with magnesium lowers, and a QR15 thru axle. This also lends to a slack, 66.5 degree head angle. Combine this with short, 426mm/ 16.77” long chain stays and you can clearly see where this is going. This keeps the bike maneuverable, easy to manipulate in downhill and aired out sections, and easier to get the front end of the bike up with the slack head angle. The drivetrain is comprised of a RACEFACE Respond 10 spd crankset with a 32t single ring and a bash guard, SRAM X-9 Type 2 rear derailleur and trigger shifter, and a SRAM PG-1030 10spd Cassette (11-36t). WTB I-23, 29" 32h, single eyelet, double wall disc-specific rims are laced to 32h sealed cartridge bearing hubs for a stout yet lighter weight wheelset. AVID Elixir 5 Hydraulic Disc brakes with 200mm front and 180mm rear rotors offer more than enough power to stop when and where you see fit. A RACEFACE Respond stem and bar complete the cockpit for a style and aggressive front end. Finally, a KS Dropper seat post raises and lowers the DB MASON Signature saddle with the flick of a switch.
