Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Transition Sentinel V3 Carbon MTB Complete Bike XT Glacier White

image for colour illustration purposes, please see below for the list of components.

The Sentinel rides the lines between planted bottomless sender and playful, poppy trail pony. This leaves the Sentinel right in the sweet spot, as Transition like to call it. It's versatile attitude helps riders excel and push their limits. The intuitive nature of the Sentinel V3 makes it 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 your rolled, now you boost. It's time to Send-It-All.


Refining the Legend

The new Sentinel may have a similar silhouette, but Transition have fully redesigned the frame with update industrial design, features and geometry to turn it up a notch. The leverage curve supports the bike higher in its travel, keeping it quick, nimble and light on its feet while leaving plenty of room for big hits. This gives it the lively, sporty attitude felt in the Spur and Smuggler without sacrificing its capabilities in rougher terrain. New size-specific chainstays and a 64° headtube angle keep riders balanced with great traction on climbs and descents. All of this crates a bike that encourages new riders to push their limits while ensuring a seasoned pro feels none.

Refined Details

Transition added internal frame storage in the downtube of the arbon frame. The BOOM Box (Burritos Or Other Munchies) is positioned below and isolated from the water-bottle cage mount. This allows you to leave your bottle installed in your cage while easily getting into the BOOM Box, reducing clutter and fuss on the trail. It also prevents noise and potential failure since it doesn't place any weight on the door itself. With an easy access lever and two supplied gear bags, riders can stow away snacks, tools, a tube, or anything else they want to have along for the ride.

Geo Adjust Flip Chip: the lower shock mount has a geo-adjust flip chip to accommodate mixed wheels, and features a new design that allows water, dirt and debris to easily wash away.

Mud Guard: the Sentinel comes with a pre-installed mudguard to protect the main pivot area, improving the bearing life.

Chainstay Protector: an all-new chainstay protector minimizes chain slap, so you can enjoy the sound of your favourite turns.

Cable ports on the side of the headtube allow for easy and simple cable routing with customizable options for mechanical or wireless shifting as well as left or right rear brake setups. The new port stops cables from getting kinked during a crash and holds them tight to prevent rattling. If you aren't using the port at all, simply cover it with the supplied insert to prevent dirt or water from getting inside your frame and keep a clean aesthetic. These ports help improve the looks of the frame while remaining functional and simple for maintenance.

Fidlock Ready

The new Sentinel is Fidlock ready. Transition know that water bottle capacity is a priority on every bike, and it can be tricky on smaller sizes. To give you the most options on all sizes, every Sentinel will come with a Fidlock base installed. Fidlock bottles give you more volume for water in a smaller space, allowing for a fidlock 450ml bottle on our XS frame, up to 590ml on SM, and up to 750ml on M-XXL.


Carbon and Aluminium Frame Options

Transition want everyone to have the bike of their dreams, so they are offering the Sentinel in both carbon and aluminium. To make this bike as accessible as possible, they crafted the aluminium frame to remain simple, keeping costs and weight to a minimum. This means it does not have the BOOM Box, but does still have the flip chip and all other features found on the carbon frame. The aluminium frame is available in Shimano Deore build as well as frame only. The carbon frame is available in Shimano Deore XT build as well as frame only. Each carbon build has the same high quality carbon construction including the BOOM Box and frame bags.

GiddyUp Suspension Design

Transition 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, they get it, sometimes you just want to grab your bike and GiddyUp, without checking your setup. When you do, it will always feel good.

Transition did this by balancing a 25% 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
