2018 Transition Sentinel Carbon

If you are looking for the sort of downhill slayer that gives you trail feedback without shattering your confidence, the Transition Sentinel Carbon might just be the perfect bike to answer your trail ambitions. Giving the 29 inch Sentinel a carbon frame hacks some weight off to make this an enduro bike that descends like a downhill slayer.

There’s no way you are going to buy this and not search out the steepest toughest trails to rage down. With the Fox DPX2 Performance Elite offering 140mm rear travel combined with the 160 up front, not to mention the 29 inch wheels that can take some burly 2.5 inch tires, you will enjoy the rollover and traction levels that will give you the confidence to start dreaming about conquering Whistler. Transition are at the forefront of pushing the long and low geometry boundaries, and with the Sentinel Carbon you’ll be practically reclining on the 64-degree head angle, 76.3-degree seat angle, while the 435mm chainstays and the super short, almost non-existent stem will keep the handling agile and snappy. With their Speed Balanced Geometry, Transition have figured out how to balance the ultra-long reach and slack head angle with the need to be able to maneuver the bike over tight trails. They manage this because the SBG lengthens the wheelbase while reducing the offset of the fork and shortening the stem. That combined with the steep seat tube angle means that the rider will be in a great position for climbing.

But most importantly, the SBG guarantees the type of playful downhill ride, which is the reason you’ve come to this party. It encourages you to push yourself that much more because you will always feel well balanced and in control. Combining the geometry with the Transition GiddyUp 2.0 suspension design will give the sort of plush ride that will make the 140mm of travel seem bottomless. This is a bike that works with you by putting you in the position you need to be; whether you are grinding up a technical trail, or pushing your limits to hit the fun factor sweet spot, the Transition Sentinel Carbon will be there for you.

But in all this engineering and fiddling to create the perfect modern enduro bike, Transition hasn’t forgotten what’s important about the basics. So you will get internal, rattle-free cable routing through the main triangle, while the rear brake line is exposed, facilitating any adjustments required. Similarly, the 73mm bottom bracket sticks with the tried and true threading, making it much easier to maintain and increasing the overall durability of the frame. Then the ISCG05 tabs will mean you can install a chain guide, but be aware the Sentinel Carbon supports only 1X groupsets. And Boost spacing will mean you can run some mega wheels to cope with the toughest runs.

If you are all about searching out the toughest runs to test yourself with your buddies doing their best to trail behind you, then the Transition Sentinel Carbon will be the 29 inch downhill bike that will answer your call of nature. Just remember, you’ll have to be the motor.
