The 2014 Diamondback Mason FS Pro is an unquestionably competition ready all-mountain renegade that is donned to the nines with race-level components. Engineers at Diamondback sought to deliver a full suspension 29er with slung back geometry that preserves optimal speed and efficiency while boasting amazing handling and ridiculous downhill ability. Mason FS Pro's frame is made from lightweight butted 6061 aluminum, the industry's go-to material for many high-end road and mountain race bikes, adored for its shape-ability, amazing strength, and resistance to corrosion. The geometry is likened to that of a downhill bike, but with just the right attention paid to the wants of XC riders coupled with the Fox Float CTD rear shock--the result is a frame that is versatile enough to go enduro, XC, all-mountain, and even some pretty extreme freeriding. To accompany this, Mason FS Pro needed plenty of strength and plenty of travel up front as well, so the choice was the Fox 34 Float CTD fork which boasts beefed up stations over their 32 offering, a whopping 140mm of travel and a 15mm quick release thru-axle. Translation: very solid downhill and cross-country control that absorbs jumps and obstacles relentlessly with no fear of breaking under extreme pressure. As an additional measure for weight reduction and all-mountain competitiveness, Mason FS Pro's designers chose a simple 1 x 10 drivetrain powered by a SRAM X1 X-Sync 11-speed crank and a SRAM X7/X9 shifter/derailleur setup. The promise of this configuration is smooth, instantaneous shifting in any conditions for any situation. Conventional wisdom amongst Diamondback's all-mountain riders who exist in the truly all-mountain environs of the Pacific Northwest is that the need for multiple front shifting options does not exist. A 32t front ring and an 11-36t SRAM cassette give you all the climbing and accelerating power you need--essentially, if you're in it for real all-mountain action, gravity will give you plenty of momentum for those insane top speeds you crave. AVID Elixir XO Hydraulic Disc feature huge 200mm front and 180mm rear rotors to provide some of the best stopping and modulation the industry has to offer. They're also designed to stave off brake fade that lesser brake systems succumb to under extreme downhill/high rotor heat situations--Elixer XOs deliver in all conditions. Add in a slew of high-performing alloy parts such as Raceface Atlas handlebars and stem, and roll it all on a super light, super strong alloy Easton Haven wheelset with Kenda Nevegal tires, and the promise is a life-changing transformation to your all-mountain experience . 6061 weapons grade aluminum frame is light, strong, fast, and has ideal all-mountain geometry and 140mm of rear suspension travel Slung-back frame geometry brings true all-mountain climbing and descending action Fox Float Rear suspension features Climb/Trail/Adjust feature so you can dominate any terrain 140mm travel Fox 34 Float is ready for any downhill, any obstacle, any terrain, any abuse A 1x10 SRAM XO/X1 rear derailleur/crank setup is simple and provides effortless shifting and plenty of gearing options for tough up and down trails Avid Elixir XO hydraulic disc brakes with huge rotors provide superior stopping and excellent modulation 29" wheels surmount obstacles easily, provide great efficiency, and have low rolling resistance Specs : Bottom Bracket:GXP Sealed Outboard Bearing Brakes:AVID XO Trail 4 piston Hydraulic Disc w/200mm frt 180mm rr HS-1 rotors Cassette:SRAM XG-1195 XO 11spd Cassette (10-42t) Chain:SRAM PC-XX1 11spd Crankset:SRAM X1 X-Sync 11spd, 32T, w/ GXP Sealed Outboard Bearing BB Fork:Fox 34 Float CTD adjust FIT, KASHIMA, 140mm travel, w/ ext. rebound, butted Alloy 1.5 Tapered steerer, 34mm Easton aluminum stanchions, magnesium lowers, w/QR15mm thru axle Frame:Mason FS 29" All Mountain 140mm travel Full Suspension Frame, 6061-T6 Weapons Grade Aluminum w/formed Top Tube, Butted / Formed Down Tube / Seatstays, Tapered Head Tube, ISCG, 142x12mm Maxle Drop out Front Derailleur:n/a Grips/Tape:DB4L "Lock on" 135mm Kraton Handlebar:RACEFACE Atlas 785mm riser bar 31.8mm Headset:FSA No57 Taper 1.5 / 1 1/8" Alloy cups, Sealed Cartridge Levers:AVID XO Trail Hydraulic Levers with external pad contact, and reach adj Pedals:n/a Rear Derailleur:SRAM X0 X-Horizon, Type 2 11spd Rear Shock:Fox Float, CTD adjust, boost valve, "LV" eyelet, 7.875x2.250" Air, DB Mission Spec, w/rebound adj, w/Climb, Trail, Descend, w/3 levels pedal platform Saddle:WTB Silverado Race SL w/ NiTi Rails Seatpost:Crank Brothers Kronolog Dropper 30.9 Shifters:SRAM X0 11spd trigger Stem:RACEFACE Atlas CNC 0 degree, 31.8mm Tires:Easton Haven Wheelset:Easton Haven 24h, 29" Clincher - UST
