2021 Transition Sentinel XT review – A powerful bike for powerful riders!

Jan 2021 · Christoph Bayer

Our expectations of the Transition Sentinel Carbon were very high for this group test,not least because the guys and gals behind the brand are really good riders themselves. Its specs look extremely promising, but can the bike deliver on the trail?

Highs
  • Rewards an active riding style

  • Lots of reserves for big impacts

  • Excellent climbing characteristics

Lows
  • Punishes a passive riding style

  • Not enough traction in rough terrain

  • Very stiff bike overall

2021 Transition Sentinel Review

Jan 2021

Since it was launched, the Transition Sentinel has been a bellwether for progressive trail bike geometry. The 2021 Sentinel is no exception, but in this case the trend indicates that trail bike geometry is stabilizing. I know this, because I went from the last generation Sentinel to this one, and even though I sized up from a Large to an XL, they're both clearly cut from the same cloth, and I have to say I'm a fan of the tailor.

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.

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
