GT Grade Carbon Pro first ride review

We take a ride on GT's new and updated gravel endurance Grade in the hills of Girona

First things first, I was a big fan of the original Grade, it was way ahead of the curve when it came to all-road endurance bikes — never a hardcore off-road beast just a much more versatile bike that could handle both road and dirt with ease.

That said, it wasn’t without its foibles. The tyre clearance was a little meagre, the lack of a thru-axle at the rear caused concern for some (though I never had any issues with it) and it was a little tall up front.


So, when I heard that GT was updating its Grade my fear was that it’d become something more dirt focussed, more ‘extreme’, more ‘adrenaline’, well I guess a bit more GT.

Thankfully, that’s not the case. What GT has done is refine a winning formula; its ride position is more roadie than mountain bike, the frame is even cleverer than the original, and for those tinkerers out there the flip-chip fork leaves room for experimentation on the bike’s handling.

My first ride on the bike was a few hours exploring the brilliant network of gravel roads, trails and singletrack surrounding Girona — who knew a road cycling hotbed like Girona had so much more to offer.

The first few kms of the ride to get beyond the city are, as you’d expect, on tarmac, and the new Grade felt great: smooth, quick to pick-up pace, and a real pedal-spinning friendly machine with its smaller adventure style 2×11 gearing (46/30, 11-34).

The smoothness of the Grade’s supple frame design makes you think you're riding much fatter rubber without the weight and sluggish downsides of plus-sized tyres

Once out of the urban sprawl it was straight onto a combination of slick, sodden, chalky, clay roads that bisect through the surrounding woods, and this lumpy choppy terrain is where the Grade’s smart chassis really came to the fore.

That, and the excellent WTB Riddler tyres, which don’t feel too compromised on tarmac and grip tenaciously on everything else — save for super sloppy mud, which thankfully we had little of.

I did have a few issues though with the Riddlers seating properly on the matched WTB rims, leading to a few stops to push more air into the tyres throughout the day.

The back end of this new Grade flexes and complies with ease, and exerts more movement than the new Roubaix I recently tested.

It feels much more akin to Trek’s Isospeed-equipped Domane, which is a much more complex method of ‘decoupling’ the seatstays from the seat tube than the Grade’s simple but very smart solution.

First ride impressions

Up front the lower, longer ride position and wide flared bar instil confidence in the Grade’s handling chops — which it has aplenty.

Descending on choppy, rooty singletrack and running into dusty fire roads as the ride trailed on and the heat rose was a huge highlight on my first outing on the new Grade.

My overriding feeling from the few hours spent on the bike was that the Grade’s chassis gives you the impression that you’re running much bigger volume rubber than the 37c’s it comes with, such is its smoothness on tarmac and its vibration smoothing performance on dirt, gravel and rooty singletrack.

That’s all the feel without the downside of heavier, wider tyres that also bring more sluggish acceleration and speed on real roads.

I also like that GT’s flagship bike seems sensibly put together; the equipment is all decent quality, the Di2 drivetrain does what Ultegra does, works without fuss or drama, and the FSA chainset is a great match. The gearing felt spot on for the terrain I was riding, but it’ll be interesting to see if GT goes the full Shimano GRX route on the Grade at a later date.

The new Grade takes what made the original great and amplifies it to one of the real highlights of the year so far

It’s also been a long time since I’ve been at a launch for a brand’s new flagship bike and it retails for the much more achievable price of £3,500. You couldn’t imagine that GT’s rivals, such as Cannondale, Specialized, Trek or Giant would launch a new bike and cap the top model at this price.

Overall, my impressions from a few hours riding are that GT has hit the high-mark again.

It’s a smart piece of engineering that champions the original’s successes and raises the performance from an endurance bike with off-road chops to a great endurance bike that could easily be a serious machine for those looking to take their gravel riding to a higher, racier level.

In fact, there will be a few new Grades lining up on the start line of this year’s Dirty Kanza and that’s not something I’d expect to have seen with the previous Grade.

I can’t really score the Grade based on just a few hours riding, but my order is in with GT already for a test bike asap. The bikes will be available mid-June and I’m itching to get back out on it as soon as I can.

Tyre clearance

We’ve already seen plenty of new and exciting bikes launched this year from the likes of Specialized, Wilier, Look, et al, with many more to come, but GT may just have the surprise hit of the summer on its hands.
