GT Sensor ST Carbon Pro: First Ride Review

by 10

The GT Sensor ST Carbon Pro is a reminder of how capable modern trail bikes are, especially if you get the geometry at such perfect balance.

Three things I loved:

  • The angles are all spot on. Not too high at the front, not too low in the middle, not too long at the back… I can’t find anything I dislike about the numbers
  • Geometry feels aggressive for the descent, yet it skips up technical climbs. Super efficient pedalling
  • It’s really predictable without feeling dull. Playfully reliable? Enjoyably consistent?

Three things I’d change:

  • I think I can feel the rocker when pedalling, it’s kind of chunky
  • The colour options are boring, logo is REALLY boring
  • The swimming pool under the shock is quite annoying

I have been testing the ‘Gloss Indigo and Wet Cement Grey with Wet Cement’ GT Sensor ST Pro. The blue paint is beautiful, it’s such a shame they added a grey fade and a really boring logo.

And that’s pretty much where my complaining ends with this bike, so far.

The tyres that come as standard aren’t too inspiring on paper (or at least the Rekon on the rear isn’t), but in reality they’re a great combo for the bike and what I’ve found it capable of riding. I seem to have plenty of traction even in the wet.

My weight is perfectly centred to keep the front end down whilst not having the back skipping out on corners. It has a really short and playful feel, yet there’s no clumsiness to the ride. I can choose a line and know how it’s about to ride, I know where I’ll end up and there’s never any corrections needed.

One of the biggest changes in my riding since getting this bike has been the commitment to line choices – I always want to take the high line through long rutted sections of trail but I’m not always convinced I can hold it (result being cross-rutting and bruising), but I can on this bike.

It goes exactly where I want it to and remains stable and smooth.

I’ve never been too excited to see SRAM G2 brakes on a bike, yet they seem to suit the ride. I don’t ever feel out of control or on my limit at speed because it’s so responsive and nippy. I don’t have that need to emergency brake, something I never feel confident with on G2s. 

The GT Sensor ST Pro has a perfect balance of components to make it a competitive price without ruining the ride quality. 

Overall

The GT Sensor ST Carbon Pro is a great reminder of how capable modern trail bikes are, especially if you get the geometry at such perfect balance. Comfortable and efficient pedalling, agile on technical terrain and aggressive on descents. I can’t help but wonder if the shorter travel is what makes this bike so much fun. It’s very consistent and predictable, and I think that could translate to being rather dull with more travel in the frame.

    It’s seems GTs new models have scuppered my chance of an Eeeb. The boy appears to want a new Fury frame instead. Harsh…. it’s tough being a parent 🙂

    Was just watching a video and the bike looks cool. In pics… it looks a little … unusual.

    Regarding the logo and text etc. Yeah, I wouldn’t even notice it if it wasn’t so bad. It’s pretty awful.

    I don’t pay that much attention to GT but as far as I know they haven’t made a desirable bike in a very long time. File them next to Cannondale for being one of the original MTB companies with impeccable heritage that have descended into ‘meh’.

    I know it shouldn’t matter that looks ugly and uninspiring, and despite Amanda high praise, it’s a reminder why those things are important, as otherwise I’d walk right past that in the shop.

    I realise I’m probably in the minority here but I quite like the subtle branding. I really dislike massive shouty logos and all those BS statements, acronyms and slogans that bike brands love to stick all over their frames. I personally prefer the colours of a couple of the new longer travel Sensors but these all seem like a good solid range of bikes that aren’t silly money.

    I like the logo but then I like GT bmxes from the 80s, which is where the typeface is from.

    If it’s anything like my few years old Alu Sensor it will be an excellent ride.

    But yeah, those graphics are gopping. The nice metal head tube badge on mine is much more classy.

    On the subject of colours I had a GT ID5 for years in what was called British Sky.

    It was actually a dull silvery grey.

    How come everyone’s slagging the logo off when the frame is the real aesthetic horror here?

    I imagine they are trying to preserve their old “triple triangle” thing, but they really need to let it go IMO.

    The geometry on this makes more sense than the 140mm version though.

    Seems reasonable.

    They need the triple thing to differentiate between it and a Trance from about 2010. 😉

    Edit: I stand corrected, 2006..

    Agreed on the colour and logo is just ‘meh’.

    The shock-paddling pool is a likely sign of other things not designed for damp conditions – I had to drill a hole in the bottom bracket shell of my Marin – it slowly filled with water on rides, and basically would ‘top out’ at the dropper cable inlet…

    Dorel to blame for that? A few other faded brands under their wings for a good while. Albeit Dorel have since sold out to Pon.

    GT is a division of the Dutch conglomerate Pon Holdings, which also markets Cannondale, Schwinn, Mongoose, IronHorse, DYNO, and RoadMaster bicycle brands;
