2020 Transition Sentinel Alloy FS Mountain Bike Frame in Grey

Season : 2020

Brand : Transition

Code : YRGNUGYRG.YLA.TNES.02.SF.

Weight : 0KG

The heat treated hydroformed alloy frameset is perfect for those who want durability and strength at a great value. The alloy frame shares the exact same geometry and suspension setup as the carbon version. For rear suspension, they worked tirelessly with Fox to create the perfect tune with the extremely impressive dpx2 rear shock. Amazing small bump sensitivity like a coil shock and excellent mid-stroke support and bottom out control. The sentinel alloy frameset features a threaded bb, external rear brake routing for easy brake maintenance, full water bottle storage inside the main triangle, boost rear end and rubber molded frame protection.

Available colours: pinot noir red, gunmetal grey
rear shock: Fox dpx2 performance elite

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.

Take the successful giddyup suspension system, add one part increased pedaling efficiency, two parts wider sag range, and three parts increased small bump sensitivity, and you get giddyup 2.0hh. Incredible pedaling performance balanced with a superb neutral, comfortable and fun feel that we're known for.giddyup 2.0hh suspension

They specifically tuned the suspension with a moderate amount of chain growth which is highest at the sag point and decreasing deeper into the travel. Because of this finely tuned wheel path, there is a notable increase in traction when climbing, without the rider noticing the chain growth fighting the suspension movement.

Giddyup 2.0hh is extremely easy to setup and it provides excellent support throughout the entire stroke of the shock so you can use all your travel without worrying about bottom out. Designed to be active while climbing, rear shock climbing platforms are not necessary. The suspension remains free to smooth out the trail, improve traction and control without sacrificing efficiency. With giddyup 2.0hh you can focus on the trail, no remotes, levers or knobs. Just grab your bike and giddyup.

Technical Information
Sizing Information
Sizing Information

At Transition Bikes our geometry is not based around gender but rather a wide selection of sizing that will be ideal for almost any sized human. We design all our bikes to be very low slung so that no matter how long or short your legs are you can find the bike that has the proper reach for your arm and torso length and then let the seatpost do the work to size the height of the bike for pedaling.

 

We highly recommend using the "Reach" measurement as the starting point for picking a size frame. The reach measurement will tell you how roomy the bike will feel when you are in an attack position standing on the pedals. Reach is now a standard that the mountain bike industry uses so you can use it to compare other bikes.

Pre-Order

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

You 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 and get it sent out 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 Dates

Estimated Delivery 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 Dates provided on product pages.
