Product Info

Like bringing a howitzer to a knife fight, the Transition Sentinel Alloy GX Complete Mountain Bike decimates trails. Starting at the back, the Sentinel has wide and rigid Boost-148 spacing paired to 140mm's of Fox sprung, Giddyup 2.OHHH suspension, combined with the new 160mm Fox 36 spearheading your good times. Finley tuned like Willy Nelson's guitar, the Transition Sentinel Alloy GX Complete Mountain Bike features a tailored Speed Balanced design that harnesses every pedal stroke of its 29" wheels and legendary SRAM 12-speed drivetrain. All this creates a rowdy ride that's sure to draw out anyone's inner mullet - whether it's long days of up and down or steep and loamy descents.

Product Details

Frame/Shock

Speed Balanced GeometrySBG ensures the bike maintains low speed agility, front wheel traction, and proper rider weight balance while actually increasing confidence in steep terrain and at high speeds. With SBG, a slacker head tube angle is combined with an all new reduced offset fork standard, preventing the front wheel from being too far in front of the rider. This improves front to rear weight distribution on the bike, which is often out of balance on long and slack bikes. One of SBG's greatest benefits is that it creates a confident steering feel that adapts to wheel speed. More stability when going fast, more agility on technical slow speed maneuvering as well as improved traction, control and confidence for any skill level of rider.

GiddyUp 2.0HH SuspensionBuilding upon the success of Transition's original GiddyUp suspension design, the new GiddyUp 2.0HH system has been refined for the modern two-wheel cowboy delivering a slightly firmer feel for more efficient pedaling, as well as more progressive travel that provides that extra little bit of bottom-out support when needed.

Fox DPX2 Performance Elite ShockCombining DPS XC efficiency and X2 DH performance, the DPX2 is the ultimate trail shock. The Dual Piston Base Valve has dedicated compression and lockout circuits for each of the three modes -- Open, Medium, and Firm. It also features a recirculating damper design found in X2 shocks, creating excellent small bump sensitivity, great mid-stroke damping support, and better control in transitions.

Drive Train

SRAM Descendent 7K DUB CranksetStrong, light, and durable. Featuring SRAM’s X-SYNC™2 tooth profile chainring, the Descendant crankset is engineered for complete chain control. Each tooth’s thickness is precisely toleranced and controlled to work seamlessly with the SRAM chain’s inner and outer links. SRAM DUB™ technology features a better-engineered bottom bracket and a new spindle design.

SRAM GX Eagle™ 12-Speed ShifterThe challenges of riding a mountain bike should be kept to roots, rocks, mud, trees, jumps, drops and breathing. Putting total control of your gear selection into the thumb of one hand, it's simple to find the right gear, right now. The GX Eagle™ trigger shifter is the control center of the Eagle™ drivetrain. Its internal works have been updated to include a 12th gear, and improved to enhance trigger feel, precision and durability.

SRAM GX Eagle™ 12-Speed DerailleurThis new GX derailleur not only answers the Eagle™ drivetrain's need for greater capacity, but it's also the next evolution of SRAM's proven, 1x-specific X-HORIZON™ design. The larger, 14-tooth X-SYNC™ lower pulley allows for a 10- to 50-tooth cassette, and also adds to Eagle's overall smooth-pedaling feel. SRAM's new Type-3 ROLLER BEARING CLUTCH™ features a smoother operation and feel. CAGE LOCK™ has been moved back and out of the way, protecting it from trail debris. And a redesigned, robust mounting system further improves the Eagle™ derailleur's performance and overall durability.

SRAM XG 1275 Eagle™ CassetteRide anywhere with this wide range XG-1275, 10- to 50-tooth Eagle cassette that provides the right gear. Fast on the flats. Control on the climbs. Dictate your own pace, anywhere. Only Eagle™ technology is the 1x drivetrain engineered for infinite freedom. FULL PIN technology uses lightweight, stamped steel cogs held together with high-strength stainless steel pins. The result: a cassette that's light and strong. The open design similar to SRAM's X-DOME™ cassette aids in mud clearance, giving you cleaner shifting performance and longer component life. New X-GLIDE™2 improves both inboard and outboard shifting, as well as chain retention.

SRAM GX Eagle™ 12-Speed ChainIt might look normal from the outside, but the engineering inside this incredible new chain design that makes possible a gear range previously found only in 2-chainring drivetrains. And it’s also the biggest contributor to the Eagle™ drivetrain’s ultra-smooth, precise, durable and quiet performance. The Eagle™ chain’s links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear on chainrings and cassette cogs. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. HARD CHROME™ technology extends the chain’s optimal performance life.

Brakes

SRAM Code RSC BrakesetCode RSC is built from the elements that made Guide a benchmark in contemporary brake design and performance, and delivers an extra 15% power to shine in all heavy duty applications. SwingLink™ and Lever Pivot Bearings ensure a smooth and progressive feel at the lever, while the additional 30% positive fluid volume ensures consistent performance even when braking harder, more frequently or with a heavier mass to slow down.

SRAM Centerline RotorsThe Centerline rotor was designed to keep the center of friction consistent throughout rotation, thereby minimizing vibration, offering consistent performance and a quiet ride.

Wheelset

Stans Flow S1 Team WheelsetBurly enough to handle the toughest of trails yet light enough to pedal all day, the Flow S1 is up for any challenge. Developed from rims ridden in Red Bull Rampage and raced on the World Cup DH circuit for years, the S1 is now ready for action. With a 1.6mm deeper profile and reinforced rim walls the new Flow S1 offers greater impact strength, for an even wider range of use, with only a minor weight gain. Strong and light 6061 alloy rims, stainless steel rim eyelets, and easily replaceable standard spokes mean the Flow S1 is built to last. Combined with faster-engaging, CNC-machined Neo hubs, the Flow S1 is the ultimate trail, all-mountain, and enduro wheelset.

Additional Features

RockShox Reverb Stealth 1x Remote Dropper PostDon’t let its familiar good looks fool you—Reverb is a whole new weapon. Its internals have been completely re-engineered to improve on its already legendary performance and to offer enhanced reliability: all the smallest details, down to the single seal, have been re-evaluated and updated to pass the hardest and longest durability tests. Additional bushing overlap also improves performance over time. This Reverb is engineered for the next-generation mountain biker.
