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.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Transition Sentinel V3 Alloy MTB Frameset Glacia White

Season:2025

Brand:Transition

Code:TR.FS.25.SENT.ALWHT

Transition Sentinel V3 Alloy MTB Frameset Glacia White

Transition Sentinel V3 Alloy MTB Frameset Glacia White. The Transition Sentinel V3 is the ultimate 'send-it-all' trail bike with 150/160mm travel full suspension. Compatible with 29" wheels 27.5 on size xs. Supplied with RockShox Super Deluxe Ultimate (205x60mm) rear shock.

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

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.



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.

Frame Protection

To help protect the frame from debrit on the trail, the Sentinel comes with a pre-installed mud guard to protect the main pivot area, improving the bearing life.
An all-new chainstay protector minimizes chain slap, so you can enjoy the sound of your favorite turns. The "pillow top" design features large rubber pillows that dampen sound and protect the chainstay.
