Diamondback's Mason AM 29'er is a bit of a departure from traditional 29" bike geometry, handling, and purpose. Mason is less XC than most 29" offerings, with a slack 66.5 head angle and short 17" chainstays. A 140mm Fox fork soaks up the rough stuff and allows for ease of control in getting the front end up. Diamondback's idea behind the Mason is to offer a simple bike that can be pedaled up quickly but shredded down with aggressiveness. The playful Mason AM 29'er retails for $2,499 for the complete bike.

Mason AM Frame
The Mason features a 6061-T6 aluminum frame with a formed top tube, a formed and butted down tube, a tapered head tube, ISCG 05 tabs and a 142×12mm Maxle drop out. 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").

Component Spec
Mason is designed to be affordable. A 140mm travel Fox 34 TALAS 29 CTD air fork smooths out the ripples up front. Race Face Respond 10-speed crankset is mated to a 32t single ring and a bash guard. Combine this with a SRAM X-9 Type 2 rear derailleur and trigger shifter, and a 10-speed 11-36t cassette and you have a minimalist approach to get you up the hill with ease. WTB 29" 32h, single eyelet, double wall disc-specific rims are laced to sealed cartridge bearing hubs for a stout, yet lighter weight wheelset. Avid Elixir 5 brakes with 200mm front and 180mm rear rotors offer plenty of stopping power. A Raceface Respond stem and bar complete the cockpit. Mason also comes specced with a KS dropper seat post with handlebar-mounted remote.

Rider Impressions
We got a little sample ride in aboard the Mason AM 29" and were impressed with the relaxed geometry and stiff, precise feel. The bike was tame enough on steep climbs to not 'need' the travel adjustment of the Fox Talas fork, but those climbing for extended periods may prefer to use this feature. Once pointed downhill, the bike really came to life, offering stable yet quick handling. We were afraid the alloy hardtail would kick like a mule, but the 29" wheels help exponentially to smooth things out. Even with flat pedals, we felt comfortable rolling the tall bike on rocky terrain. Cornering is a joy when pushing the big wheels into turns, much attributed to the slack front end and short stays.

A Preview Of Things To Come
Diamondback will be responding to the mid-travel 29'er crowd with the Mason FS. The 140mm front and rear travel bump-taming aggressive geo shred machine could be available as early as spring 2013. Although we didn't get a chance to ride the only prototype in existence, we can comment that the shape of the frame combined with the graphics scheme is a visual treat. Expect a similar component spec to what you see here, which includes Fox CTD air shocks, XO Trail brakes, Race Face SixC Carbon cranks, Easton Haven 29" wheels, and a RockShox Reverb. With that type of spec, we're guessing somewhere around $6k, and a progressive all-mountain geometry similar to the Mason AM hardtail.

 Agreed.....I REALY can't stand 29'er bikes and all the BS hype around them. The wheels feel noodly no mater what. HOWEVER, that hardtail is actually one I would like to try out a bit.

 The wheels you rode bman33, were not built properly then.

 I f*ckin' love my 29er. What I REALLY can't stand; is when people accentuate a word by putting it in ALL CAPS, then spell that word wrong. Anyways, it would be nice to win one of those bikes; if only to buy a better frame and put all the DB's parts on it.

 I don't get them either
  • + 3
 Not only that, but I signed up, did the last quiz, and when I try to sign in now, it says I never created an account. Can't even recover password, zilch. Well isn't that just neato.... It seems the IT end of this is screwing up pretty good.

 To add to this, it won't even submit now. This "contest" is falling apart or they weren't prepared to handle the load stress from a big influx of people using the site and/or contest page.

 Ya haven't got my first confirmation email yet either...
  • + 1
 Any of you guys get one yet? Both of mine rolled in today at the same time, around 11am. Dunno why it took so long, but oh well.

 Hey all… We apologize if you have not received the confirmation email from us. Our web team is working to ensure that you all have this now and you should be receiving this shortly. The email confirmations go out in batches each day. If you have not received your confirmation email, you may want to check your spam filter as it’s likely that it landed there. Those who still not get one may have typed in their email address incorrectly.

The majority of entrants have already received theirs though. I can confirm that.

Thanks for your patience.

 If wish PB would start telling us what size the bike is they are showing us in these great pictures. Since size can make a huge difference in the look of a bike it would be nice to know that the pictures we're drooling over are of the actual size bike we would be buying/riding.
  • + 1
 Providing the actual weight of the bike being tested would be nice as well. Of course the manufacturers might not like that in some cases but just throw a disclaimer on there like "as tested weight, actual weight may differ depending on components etc."

 Looks really fun, would be great for local dh style trails. Hope I win one. I will be looking to test ride the fs version when it comes out, head angle has been keeping me off a 29er so far, can imagine it being seriously fast for big rough descents.

 Im usually a 29er hater, but with a decent head angle on the f/s ill take it for a ride

 Bah, some sort of website error. Submit button doesn't work. Sweet looking aggressive 29er though. Diamondback is really stepping their game up.

 I use to own a 1984 DB Viper when I was a kid, one of the last DB's made in the USA. It would be cool to put the Mason 29 in the garage

 Guess I have to wait till next Thursday before buying my next bike. The Mason is going to be a bike that converts a number of 29 haters.
