2024 Transition Sentinel Alloy NX 29"

GiddyUp Suspension Design
We want to make it as easy as possible to experience great rear suspension performance. The GiddyUp suspension system is designed to behave intuitively across a broad range of setup. Because, we get it, sometimes you just want to grab your bike and GiddyUp, without checking your setup. When you do, it will always feel good.

With nearly 24% progression and the most current evolution of our GiddyUp suspension kinematic, the Patrol has an excellent balance of support and small bump sensitivity. Anti-squat is tuned to enhance pedaling performance and provides a platform to push against when pumping, without sacrificing a bottomless feel when needed.

The GiddyUp suspension layout is tuned to work correctly with both air and coil rear shocks. Riders are able to add or remove volume spacers in the rear air shock to suit their individual riding style and there is plenty of bottom out control with air or coil shocks when things get rowdy. The Patrol has 160mm of rear wheel travel when used with the supplied 205mm x 60mm stroke shock. It is also possible to install a longer, 205mm x 65mm stroke shock to increase the rear wheel travel to 170mm if you are after a longer travel experience.

A suggested sag range of 27 - 33% allows the rider to tune the feel of the bike; from a firm and snappy jump and slash mode, to a more supple and active full on party mode. Wherever you end up, you can focus on the trail without remotes, levers or knobs. Just grab your bike and GiddyUp.

Speed Balanced Geometry
SBG 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 a 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.

Lifetime Warranty
At Transition Bikes we take pride in the quality of our products and are stoked to offer a lifetime warranty for the original owner and our stellar crash replacement program. We got your back so you don't have to worry about your bike.

Frame Material
The Sentinel carbon uses premium Japanese Toray fiber using a unique latex-coated EPS molding process to create tighter edge radius control using less material.

Pivot Technology
Collet main pivot technology improves rear end stiffness and keeps your pivot hardware tight. Additional bearing shields prevent main pivot bearing contamination when washing your bike or riding in wet conditions.

Gear Accessory Mount
Our underside top-tube accessory mount allows you to carry a spare tube or other goodies safely on your frame in case you are looking to ditch the backpack.

Frame Protection
We keep your bike rides quiet and your frame safe from damage with fully integrated, flush-mounted rubber frame protection at all critical areas. In addition to downtube and seatstay protection, the ribbed chainstay protector features expanded coverage of the rear dropout pivot area.

Enduro Max Bearings
We exclusively use Enduro Max suspension pivot-specific bearings in standard sizes that are readily available worldwide. Dual bearings are used at the dropout pivots for frame stiffness and additional c-clips lock the rocker bearings in place under torsional loads.

User-friendly Cable Routing
To simplify maintenance and keep your bike noise free, the rear derailleur cable is routed through guide tubes in the front triangle and chainstay.

Threaded BB
A standard 73mm threaded bottom bracket shell makes crankset maintenance hassle-free and prevents unwanted press-fit BB related noises.

Mega Seatpost Insertion
Dropper posts keep getting longer so we combined short seat tube lengths with mega seatpost insertion to help get your saddle completely out of the way.
