Bike Review | Transition Sentinel GX

Apr 2020

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.

Review: Transition's New Sentinel V2 - Now With More Travel

Apr 2020 · Mike Kazimer

The Sentinel bumps up to 150mm of travel, along with a new frame shape and updated geometry.

Highs
  • 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

Lows
  • 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

Transition Sentinel Carbon GX: first ride - MBR

Jul 2019 · Mick Kirkman

The full carbon Transition Sentinel frame looks super slick, and ticks just about every box in the ‘modern geometry’ checklist.

Highs
  • One of a handful of 140mm travel 29ers that are truly Alpine ready

Lows
  • Less urgent and spritely pedalling than plenty similar travel rigs

Transition Sentinel Review

Dec 2018 · Christoph Bayer

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.

Highs
  • Unstoppable on demanding tracks

  • Very stable at high speed

  • Great spec

Lows
  • 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

[Tested] Transition Sentinel X01 Carbon

Aug 2018 · Mauro Franzi

After our recent test of the Transition Patrol, many readers asked for a comparison with the Sentinel, the Enduro 29er from the American brand. We got ahold of the Sentinel in its top-level, X01 Carbon build, for another test and a head-to-head comparison between the two models. This is therefore going to be a slightly different review, in which we will also compare the two bikes throughout. Despite the different length travel, 160mm at the front and 140mm at the rear for the Sentinel, there are a lot of common aspects, for example the Speed Balanced Geometry and the suspension scheme: a four bar

2018 Transition Sentinel X01

Mar 2018 · bturman Rconroy

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.

[R]eviewed: Transition Sentinel

Feb 2018 · Scott Prendergast

WELL LISTEN UP KIDS! WE REVIEW A LOT OF BIKES AND FROM TIME TO TIME WE GET ONE THAT’S ALWAYS A BIT OF A SURPRISE. THE TRANSITION SENTINEL IS NO JOKE, AS A MATTER OF FACT WE DON’T WANT TO GIVE THIS BIKE BACK. This rig bleeds as much style as Mick Jagger on the dance floor. A long travel (140mm rear, 160mm front) 29’er is reasonably new for Transitions range, previously they had the Smuggler with 115mm of rear […]
