The Hard Charging
All-Rounder

The Sentinel inspires confidence like you’re wearing full body armor.

It’s forgiving do-it-all attitude truly blurs the lines between planted bottomless sender and playful poppy trail pony. Whether you’re chasing EWS dreams or just a weekend afternoon escape, it will bring out the best in you. So easy to get acquainted with you’ll find yourself sending lines, jumps and maneuvers you always felt were beyond your ability. Where before you went around, now you go over. Where you pushed up, now you pedal. Where you rolled, now you boost.

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 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.

FRAME FEATURES

1. 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.

2. All Carbon Construction
Full carbon frame made from premium Japanese Toray fiber with a tailored blend of 24T and 30T materials to create the right balance of frame stiffness, strength, and impact toughness. Our unique latex coated EPS molding process allows for sharper frame lines and tighter edge radius control with maximum strength to weight ratio and less wasted material.

3. 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.

4. 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.

5. Badass Bearings
We exclusively use EnduroMAX 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.

6. 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.

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

8. Tire Clearance
Ample clearance for mud and tires up to 2.6" width.

9. 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.

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

11. Press In Headset
Our ZS44/ZS56 press in headset gives you the freedom to use angle adjust headsets if you feel the need to make your bike a touch slacker or a touch steeper.

Angleset headset does not come with framesets or complete bikes.

12. Water Bottle Compatibility
We keep your water bottle clean inside the front triangle so you can keep hydrated without worrying about mud making it to your mouth.

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.

We did this by balancing a 24% progressive leverage curve with a consistent linear rate of change. Anti-squat is tuned to enhance pedaling performance and acceleration. Overall chain growth is moderate and reduces after sag so chain tension doesn't get in the way of the suspension working.

This translates to killer small bump compliance and great mid-stroke support that gradually transitions into an end of stroke ramp that is subtle, yet supportive. The amount of consistent progression is carefully optimized for both air and coil shocks. Riders are able to add or remove volume spacers in air shocks to suite their individual riding style and there is no compromise to bottom out support with coil shocks. The Sentinel has 150mm of rear wheel travel when used with the supplied 205mm x 62.5mm stroke shock. It is also possible to install a shorter, 205mm x 57.5mm stroke shock, to decrease the rear wheel travel to 140mm.

A wide usable sag range of 25 - 35% allows the rider to tune the feel of the bike; from poppy and playful, to planted for plowing. Wherever you end up, you can focus on the trail without remotes, levers or knobs. Just grab your bike and GiddyUp.



"Personally, I've always been a bit averse to longer travel, 29" wheeled bikes with much more than 130mm to 140mm of travel as they've always just felt like "a lot of bike" to me, at least for the riding at home in Santa Cruz, but the Transition Sentinel has me rethinking that. I've never ridden a Horst link bike that climbs so efficiently, never been able to manual a bike with 440mm chainstays so easily, and I've never felt so centered and "in it" on a bike

On my first romp aboard the Sentinel, I was overshooting jumps and drops by bike a bike length or two where I used to kiss the knuckle on my other bikes. It has so much pop and perfectly walks that fine line of freakishly nimble in the tame, yet sure footed in the gnar. The frame is substantially lighter in weight than I had expect from Transition, and the new industrial design is easy on the eyes while still nodding to functionality and smart features. As far as versatility is concerned, it's a nice option to be able to run a shorter 57.5mm stroke shock and 150mm fork if you wanted to err toward more of an all day ride - you could also go the other way and put a coil shock and a 170mm fork on if you really wanted to get gnarly. The increased rate of progression is absolutely dead on and they nailed the kinematics and tune." - MTB-MAG.com

"I kept going back to this feeling that it just excelled everywhere. I really liked pedaling on this bike. Like, a lot. Whether it be technical single-track or endlessly winding fire road"

"The more progressive leverage curve gives the back end a responsive lively personality under foot with a magical bottomless feel towards the end of its travel." - Bike Magazine

"Wow, the Sentinel packs it all into one rig. I've cleaned more techy climbing sections, felt more confident on blind trails, and overall had more fun riding the Sentinel than many previous bikes. If you're looking for a beast of a bike for a mix of trails and terrain that can still hold it's own when it's time to pedal bike to the top, the Sentinel is for sure the bike for you." - MTBR.com

"The new version is no slouch when it comes to straight-line plowing, but now I'd categorize it as more of an aggressive all-rounder rather than a downhill specialist. It's well-suited to my favorite types of rides - big, long adventures with a focus on steep and rough trails that can only be accessed after a sustained uphill grind" - Pinkbike.com

"After a few weeks worth of rides, the new Sentinel is a honkin' beast of a trail bike. Yes, it still feels like a trail bike. Despite the numbers, it doesn't suffer from feeling like too much of a plow - it pops when you want to pop, switches from one side of an s-turn to the other, and provides enough length to move about forward and aft to distribute traction as I need it. Like its predecessor, it falls somewhere between trail bike and all-mountain bike." - NSMB.com
