As 29ers become ever more prevalent, many companies are exploring how far they can take it. Geometry limits to some degree the direction some might go with this, and thus has led to a wide variety of XC oriented 29ers but not much more. For us riders here in the northwest, we needed a 29inch offering that was a little bit more capable. Enter the Mason All Mountain hardtail. This rig is slack and low slung – meant for today’s shredder who wants to pedal up but charge down with aggressiveness.
The 2014 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, a direct mount front derailleur mount, ISCG tabs and a 142×12mm Maxle drop out.
Loading up the front end is a ROCKSHOX Sektor 29 Silver with 140 mm of Travel, a 15mm Maxle, Solo Air, external rebound adj. w/turnkey lockout, Magnesium Lowers, and an Alloy 1.5 Tapered Steerer Tube. This also lends to a slack, 66.5 degree head angle. Combine this with 433mm/ 17.05? 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. Because the long travel fork lifts the front end of the bike up pretty high, we designed a formed, low top tube for better clearance over the bike.
32h AM290, 29” double wall disc specific rims are laced to sealed cartridge bearing hubs and SRAM MAXLE QR for a stout yet light weight wheelset. AVID DB1 Hydraulic Disc brakes with 180mm front & 160mm rear G2 rotors offer more than enough power to stop when and where you see fit.
Benefits of a 29” wheel are pretty apparent:
- Angle of Attack – Larger wheels decrease your angle of attack by allowing you to roll over obstacles easier and faster. Bigger wheel = smaller obstacle.
- Momentum – A larger wheel enables one to carry momentum easier though obstacles.
- Surface Contact – 29”wheels are less prone to sinking in soft material such as sand and mud due to the larger contact patch causing lower ground pressure. The longer contact patch increases cornering and straight line traction
- Stability – The relative position of the bottom bracket/cranks to the axles in the wheels also means that your relative center of gravity is lower. This results in a feeling of riding “in” the bike rather than on top of it.
- Tire Clearance – with more tire choices than any platform, the 29”wheel easily accommodates off road as well as commuting tires.
- Taller Riders – 29" bikes tend to offer taller riders a more “natural” frame geometry.
The drivetrain sells itself with a RACEFACE Ride w/ NEW Narrow-Wide 32t single ring – 10 spd crankset and a Raceface outboard bearing bottom bracket. Combine this with a SRAM X-5, Mid Cage 10spd rear derailleur and trigger shifter, and a SRAM PG-1030 10spd Cassette (11-36t) and you have a minimalist approach with a variety of options to get you up the hill with ease.
Get a feel for the cockpit with our customized DB 6061 Aluminum 3D forged stem with DB ProBar Handlebars, a 30.9mm Alloy DB Seatpost with Micro Adjust action, and the DB MASON Signature saddle; all systems go for launch.
With all of the new 29ers on the market, isn’t it great to know that our gravity oriented friend can play too?
The 2014 Mason comes in a Raw White paint scheme as a complete bike in four sizes: SM (15.5"), MD (17"), LG (19"), XL (21").
