Mason Frameset

Win a Podium 7

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.

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 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, ISCG 05 tabs and a 142×12mm Maxle drop out.

With the frame comes a FSA No57 Tapered headset, a DB MASON Signature saddle and, wait for it… a KindShock Drop Zone 125mm dropper seat post w/remote. Pretty good eh?

The Mason comes in a Raw Red paint scheme and is available as a frame only or a complete bike in four sizes: SM (15.5"), MD (17"), LG (19"), XL (21"). With all of the new 29ers on the market, isn’t it great to know that our gravity oriented friend can play too?
