Pinarello isn't aiming for the bikepacking adventure market with its new Grevil. The stiff frame with its aerodynamic tube sections and large ratio gearing are aimed purely at maximum velocity, making it a surprisingly fast gravel-bashing speed machine. There are compromises, though, and I'm not just talking about the price.

  • Pros: Confident handling on the rough stuff; excellent power transfer
  • Cons: Pricey against the opposition; stiff rear end can be skittish; budget wheels

Not everyone wants to carry baggage when they go for a ride, or spend days away from home sleeping in a ditch, but this is the type of thing most gravel/adventure bikes are designed to turn their hand to. The Grevil is designed for just getting out there and smashing it about off the beaten track, and that's something it does very well indeed.

Ride

With a lot of design cues from Pinarello's top end road bikes, and the reasonably low front end for a gravel bike, the Grevil delivers bags of fun when it is being ridden hard.

On loose gravel tracks with the practically slick tyres scrabbling for grip, the feedback through the frame and fork allows you to just get on with the job of powering forward. Shifting your bodyweight and making tiny tweaks to the steering is all it takes to keep the bike just on the edge for maximum grins.

The steering is edging towards quick on the rough surfaces, which makes for some fun moments as you tackle more challenging terrain, but I never found the Pinarello to be overly twitchy.

On the wide, flowing gravel byways that I spend a lot of my time on, you can achieve some impressive speeds, with the odd descent seeing 45-50mph possible.

Pinarello Grevil riding-6.jpg

With the surface pretty much hardpacked you can let the bike go a bit without issue, although the whole trail can be strewn with random large stones and potholes, not to mention the odd part of the top layer being covered in sections of loose gravel. Travelling at speed on that type of terrain, all these little challenges are rushing at you in a blur of dust and vibration, but thanks to the reasonably light weight and overall flickability of the Grevil you can change line or bunny hop in an instant.

When it comes to climbing the Grevil doesn't disappoint either, thanks mainly to the huge size of that bottom bracket junction and thick chainstays for exploiting as much of the power you are putting out as possible. Getting out of the saddle sees the Grevil just get on with the job of propelling you uphill without the slightest whiff of flex.

Pinarello Grevil riding-2.jpg

The downside to this stiffness is that over rough terrain at speed, the rear end of the bike can get bounced around quite a lot, leaving the back wheel feeling a little flighty as it spends just as much time off the ground as it does on it.

It hampers comfort a bit, too, with the Pinarello really calling out for a flexible seatpost like the S15 VCLS found on Canyon's carbon fibre Grail CF SL 8.0 SL to take the sting out of the trail.

Thankfully, up front there are no such issues, which I was surprised about when looking at the chunky profile of the head tube and fork legs. I wouldn't say it is plush, but considering how narrow the handlebar and tape is, I had no issues with pain or fatigue through my hands or wrists, and I don't tend to wear gloves either, even off-road.

> Cyclo-cross vs adventure/gravel bikes: what's the difference?

It's not just off-road that the Grevil performs, though, it's also pretty decent on smoother tarmac. Swapping out the 650B wheels and 47mm tyres for a set of carbon fibre 700Cs and 28mm slicks sees the Pinarello become a great cruiser, a slightly more relaxed Prince FX, if you like – after all, they share a lot of the same design cues.

The handling isn't quite as sharp on the Grevil once it ventures onto the tarmac, but on the whole it feels just like a quick endurance road machine thanks to the quite racy position.

Frame and fork

It's got to be said that the Grevil's frame design really divides opinion when it comes to the shape of the tubes, but I quite like it, especially in this colourway.

Pinarello Grevil -7.jpg

Like I said up top, the Grevil takes much of its shape from the Prince and Dogma road models. Things like the profiled head tube and that quirky down tube, which is designed to improve airflow over your water bottle and cage. I'm not sure how much it helps if you make use of the spare pair of bosses underneath the tube, mind.

The Onda fork isn't immune to efforts to smooth the air either, with its comically named Fork Flap, an extended part of the fork leg at the dropout designed to deflect airflow around the disc calliper.

Pinarello Grevil -10.jpg

On the whole, I know the Grevil is about being a fast gravel racer, but I can't help thinking, why? Being on the gravel isn't really like slapping out the miles at speed like on the road, where aero tweaks do make a minimal difference, so I don't really see much need for all of this wind-cheating design.

In the relatively short time that gravel bikes have been around we've seen tyre clearance increasing by a fair margin, and with the adoption of smaller 650B wheels there are even more options. If you are running 700C wheels on the Pinarello you can go up to a max of 42mm, which isn't too bad – for the type of riding I do I'm happy with 38mm to 40mm tyres. With the standard 650B wheels attached, you can go up to 2.1in, around 53mm in width.

Pinarello Grevil -14.jpg

To accommodate these tyre clearances you can see that Pinarello has dropped the drive side chainstay to provide clearance between the wheels and the crankset.

It's good to see the Grevil getting a threaded bottom bracket on a bike that is going to be spending plenty of time in dusty and muddy conditions, but some will be a little perturbed to see the threading for the cups is of the Italian persuasion.

Where the cups of a BSA threaded bottom bracket have opposite thread directions for the drive and non-drive sides to stop them coming undone through the pedalling action, the Italian options both follow the old righty-tighty, lefty loosey school of thought. Some people have had issues with the cups loosening, but in years of riding a steel frame with the same setup I've never had an issue.

The frame itself is made from Toray T700 carbon fibre, which sits at the upper end of the manufacturer's range of composites. The frame needs to be stiff yet comfortable, plus being carbon fibre it also needs to stand up to some abuse, especially with its off-road intentions, and it looks as though Pinarello has found this grade to offer the best balance of properties.

Pinarello Grevil -8.jpg

As you'd expect, the Grevil has full internal routing for the cables and hoses on both the frame and the fork, which works with both mechanical and electronic groupsets.

Pinarello Grevil -9.jpg

Front and rear, the brake callipers are attached via flat mounts and there are 12mm thru-axles at each end too.

Overall, it's a nicely finished frame and the paint is pretty hardwearing everywhere – except for the seatpost. Moving it up and down in the frame to get my fit spot on has left a few scratches.

Pinarello Grevil -11.jpg

Geometry

The Grevil is available in six sizes, with effective top tube lengths of 510mm through to 600mm. Our test model with a 535mm top tube has a reach of 368mm and a stack of 537mm, which is in race territory for a bike of this ilk, helped mostly by the short 135mm head tube length.

Pinarello Grevil -1.jpg

Slamming the stem you can quite a low-slung position on it for powering along on the flatter sections, which I like.

Pinarello Grevil -5.jpg

The geometry isn't that steep for a bike designed for speed, with a head angle of just 70.5 degrees (it increases by half a degree on each size) and a seat angle of 73 degrees. It works, though; as I've already said, the Grevil never feels sedate in its handling.

Groupset and finishing kit

This model gets a full Shimano Ultegra R8000 hydraulic groupset, and as you'll see if you read that review, it can't really be faulted.

Pinarello Grevil -15.jpg

The only slight difference here compared to the usual road setup is that the Grevil gets an Ultegra RX800 rear derailleur, which includes a clutch to keep the chain tension high to stop flapping when you're hammering over rough surfaces.

Pinarello Grevil -13.jpg

I've never had a chain unship using the standard R8000 mech off-road, but the RX800 version does keep the noise down and will protect your chainstay from the bouncing chain.

All of us here at road.cc have our favourite gearing setups for gravel riding, and while some are big fans of the 1x system I'll take a double ringed chainset any day of the week – it just suits the way I ride and is ideal for the type of terrain most of my training and testing takes place on.

While some brands are using smaller rings on their double setups, I think for the race intentions of the Grevil a 50/34 is the right choice, paired to the 11-32 tooth cassette. I had all of the gears I needed for every eventuality. If, however, you are likely to deck out the Grevil with frame and bar bags, adding weight, or live in a hilly area, then a 1x option might well be better for you, with a wide ranging cassette giving you lower gear options.

> How to get ultra-lower gearing for gravel bike adventures

Shimano's hydraulic brakes are brilliant – really progressive and offer loads of power. Pinarello has gone for 160mm diameter rotors front and rear and I'd say that is bang on. On the road 140mm is the norm, but with the unpredictable terrain off road and the fact that some of the descents can be steep and technical, having the larger rotors gives extra peace of mind.

The rest of the finishing kit comes from Pinarello's in-house Most brand.

The handlebar is alloy, and although on a road bike for this sort of money I'd be expecting carbon, I'm quite happy with aluminium for off-road riding, especially once the inevitable crash occurs.

The bar itself has a very small diameter either side of the clamping area, so should you not get on with the rather minimalist Most tape you can swap it for something better padded without making the grip size overly fat.

Pinarello Grevil -6.jpg

There is a slight flare to the drops, but I'd like something a little wider like the 12-degree flare found on the Genetic Drove.

The stem is also alloy and does a fine job, plus you get the added aero benefit of the tail end of it with accompanying spacers.

Pinarello Grevil -4.jpg

I got on quite well with the saddle, too, liking its stubby shape with a profile that is quite similar to one of my favourites, the Prologo Dimension Nack. The padding is pretty firm but it is definitely supportive, and its short length means you can get down in the drops without crushing anything.

Wheels and tyres

A lot of brands spec cheaper wheels on their bikes to keep costs down, but not usually as markedly as those provided by Pinarello.

The 650B version of the Fulcrum Racing 7 DB isn't a bad wheelset, to be fair. It's a little weighty at around 1,800g but the wheels are solid performers and took ever knock and clatter that came their way on the trails. The Grevil is screaming out for something better, though.

Pinarello Grevil -16.jpg

For this kind of money I'd be expecting more, like Fulcrum's Racing 3 DBs. Okay, you won't drop a huge amount of weight, but they have a much nicer ride quality to them.

I tested the Vittoria Terreno Zero G20 tyres a few months back and found them to be quick rolling and grippy, especially on the road.

Pinarello Grevil -12.jpg

Having very little tread means they are okay on hardpacked tracks and trails, but if the surface is loose you are left with a bike that will slide all over the place. Fun, yes, but not very constructive when it comes to forward motion.

Pinarello Grevil -17.jpg

They are robust enough and still look in pretty good nick, although I did pick up one puncture from a pretty hefty thorn. They're tubeless ready, but Pinarello hasn't set them up that way, sticking with inner tubes.

Value

Brands like Pinarello command a high price thanks to their heritage, fashion and, in recent years, wins of the major tours by riders like Wiggins, Froome and Thomas aboard their bikes, and if you are happy to pay for it then fair play, it's how the world works after all.

There are a lot of options, though, especially if opening up your wallet is driven a little more by your head than your heart.

Canyon's pricing is aggressive, and thanks to its large scale, direct-to-consumer setup many brands struggle to compete, which is why the Grail cannot be dismissed.

The Grail CF SL 8.0 SL I mentioned at the top of this review is literally one of the best bikes I have ever ridden. For a similar build to the Pinarello it's nearly a kilo lighter and just so flickable and precise on the gravel.

> Buyer's Guide: 22 of the best gravel and adventure bikes

I'll admit, though, that the Grevil comes very close to it in terms of handling and ride quality, aside from those stiffness issues I mentioned earlier. Both bikes are about gravel racing rather than adventure, and they both do it very well.

The thing is, the Grail we tested came in at £3,249 against the Grevil's £4,500 – and the Canyon came with carbon wheels.

You can get the non SL version with alloy DT Swiss C 1800 wheels and the cool carbon cockpit plus the flexible seatpost for just £2,349!

It's not just Canyon, either: a similarly specced Wilier Jena Ultegra will set you back £3,399.99, and Mat really liked the frameset.

Conclusion

Take price out of the equation for a minute and against a lot of the other gravel bikes I've ridden the Grevil is very good indeed. I love the way it rides, and the way it looks, and I will be sad to see it go back. But from a consumer point of view, it'd be hard to justify laying out this sort of money on it.

Verdict

A nicely balanced, quick-handling gravel race bike that is up there with the best, but the price is hard to swallow

Tell us what the bike is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about the bike?

Pinarello says, "Grevil is made to eat the dust, wherever you want to explore, it goes ... fast."

That pretty much sums it up, to be fair.

Where does this model sit in the range? Tell us briefly about the cheaper options and the more expensive options

This is the only model in the range at the moment available as a complete bike; it does come in both 1x and 2x groupset options though.

The Grevil+, which uses a more top end carbon fibre, is available as a frameset only.

Frame and fork

Overall rating for frame and fork
 
8/10

Tell us about the build quality and finish of the frame and fork?

The Grevil is a quality frameset although I'd say that you need to be careful getting the saddle height right as the paint finish of the seatpost scratches as you move it up and down.

Tell us about the materials used in the frame and fork?

The frame and fork both use Toray T700 UD carbon fibre.

Tell us about the geometry of the frame and fork?

For this type of bike the riding position is quite long and low – you can tell it has race intentions. Full details here.

How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?

The stack and reach measurements in this size give a ratio of 1.45 which is much more aggressive than I'd expect.

Riding the bike

Was the bike comfortable to ride? Tell us how you felt about the ride quality.

On the whole yes, but it could do with some damping at the rear end.

Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?

Everywhere it needs stiffness, it has it.

How did the bike transfer power? Did it feel efficient?

Yes, very efficient mostly thanks to that huge bottom bracket area.

Was there any toe-clip overlap with the front wheel? If so was it a problem?

No.

How would you describe the steering? Was it lively neutral or unresponsive? Just nudging the lively side of neutral.

Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?

You can have a bit of fun with the Grevil. The handling is quick enough that you can quickly get out of shape but there is so much feedback from the frame that you can really feel what the bike is doing beneath you, so you can bring things back under control.

Which components had the most effect (good or bad) on the bike's comfort? would you recommend any changes?

I would like to see a more flexible seatpost than the aero job you get with the Grevil for a more comfortable rear end.

Which components had the most effect (good or bad) on the bike's stiffness? would you recommend any changes?

It's a good all-round package.

Stu knocked out his first road.cc review back in 2009 and since then he's chucked the best part of seventy test bikes around the West Country, a couple of them quite literally! With three alloy and two steel bikes in his fleet he's definitely a metal man (that'll be the engineering background) but is slowly warming to that modern carbon fibre stuff along with fat tyres & disc brakes.
It's not all nostalgia though, after spending the last few years in product design Stu keeps banging on about how 3D printing is going to be the next big thing and he's a sucker for a beautiful paint job too.

I agree, my guess is that it is the fat tires and fat'ish frame.

Slight tanget: why are all these gravel bikes muted browns/greens/greys? You can get cyclocross and MTBs in any crazy colour you want, but gravel bikes ... uniformally dull.
