Can this revamped long-travel 29er out-perform the original? - Mtbr.com

Not all that long ago, I wrapped up a test on the new Transition Sentinel . Turns out, I liked the bike enough that I really, really didn’t want to give it back. So I built it out with a smattering of my favorite parts as of late. As far as the bike itself goes, I love the do-it-all but still have fun spirit the Sentinel has. With 160mm front and 150mm rear travel, rolling on 29 “wheels, it’s no surprising what a capable bike it is, but what surprised me was just how nimble the bike was and how

There’s more than meets the eye with the latest and greatest version of Transition Bikes’ Sentinel. The crisp edges and gentile curves are surely drool-worthy, but if a bike doesn’t ride at least twice as good as it looks, what’s the point? Thankfully, the sorcerers at Transition put the utmost importance on how a bike rides, the reason they’ve gone above and beyond to develop their SBG geometry, adapting their numbers to match the needs of modern-day trail bikes. As for the new Sentinel, the biggest update is an extra 10mm of travel. While this might not seem like much, it brings the bike into a new category of sendability. The steadfast feeling that the company’s bikes are so well known for, simply because it’s perfectly suited to the Northwest, hasn’t wavered, yet they’ve also managed to ramp up the responsiveness and playfulness.

What do you do to update a bike that was already ahead of its time, like the Transition Sentinel? Not much. And as it turns out, that was just enough.

The Sentinel bumps up to 150mm of travel, along with a new frame shape and updated geometry.
Great all-rounder for riders with the right terrain
Relatively light considering the build kit
Wide range of sizes, room for long travel dropper posts
Knocking noise from Super Deluxe
Water pools up underneath lower shock bolt
Not the mini-DH / smash-through-everything bike some riders may be looking for

The full carbon Transition Sentinel frame looks super slick, and ticks just about every box in the ‘modern geometry’ checklist.
One of a handful of 140mm travel 29ers that are truly Alpine ready
Less urgent and spritely pedalling than plenty similar travel rigs

The Transition Sentinel is very similar to the competition in terms of travel and weight. In practice, however, the other bikes were not able to keep up.
Unstoppable on demanding tracks
Very stable at high speed
Great spec
Gets bored on simple trails
Requires an active riding style
On tight climbs, the front wheel tends to want to flop from side to side

Transition's fresh approach to geometry results in a bike that handles incredibly well, encouraging you to get after it that much harder. It's portly but built to last.
