I try not to do too much research about the latest bike I'm riding until the test period is pretty much over, so as not to influence my judgement, and when I found out the Cube Agree C:62 Pro is actually aimed at the endurance market I was amazed. It all makes sense when you take a glance at the geometry table, but when you are out on the road, boy does this thing want to fly.
Cube's brief for the Agree C:62 was to create a bike that can be ridden long and hard while responding to your every whim. It feels so exciting to ride. The frame is buzzy and really in tune with what is going on beneath you; every tiniest detail of grip is sent back to you from the frameset, which gives you a real confidence to push the bike hard into the bends.
Stiffness levels are impressive, too, which makes the Cube feel lively and it responds well to acceleration and climbing hard out of the saddle. One surprise was finding out the overall weight: 8.05kg (17.74lbs). The Cube feels way lighter than this, and it just goes to show that it is often worth ignoring the numbers on the scales.
Descending is also a joy, with the 72.5-degree head angle giving a precision and sharpness to the handling you really shouldn't expect. You can really chuck this thing through the bends and delight in its ability to get you to the bottom of the hill without drama.
But while the steering is quick, there is a real feeling of stability which comes with the 1,006mm wheelbase. It just takes the edge off what could be a twitchy ride and really helps to make this a bike that you can ride for a long time at speed.
On the flat the Agree covers ground quickly with a decent balance of speed and comfort. It isn't the plushest ride, right on the edge of what I'd fancy doing a 100-mile sportive on, but it's far from jarring.
I'd certainly say the design brief has been hit. If you don't want the slammed position of a race bike but still want to ride fast and far then the C:62 really manages to strike a sweetspot between the two.
As I've hinted at above, the frame and fork of the Agree are slightly at odds with what you'd normally expect from an endurance bike. A lot of companies relax the geometry while also softening up the frame to increase comfort. But what if you still want that performance, the rigidity from the frame and fork, but with tube lengths that aren't going to see you stretched out to the extreme?
This is exactly what Cube has done here. It's created a fast performance bike that anyone can ride, regardless of flexibility.
We've got the 56cm model here, which has a 560mm top tube and a 170mm head tube, with a reach of 390mm (the horizontal measurement from the centre of the bottom bracket to the top of the head tube), and a stack of 573mm (the vertical measurement between those points).
This creates a ratio of 1.47 which is sporty; most endurance bike figures come in around the 1.5 to 1.55 area. Probably the biggest key to its mild manners is the chainstay length; at 412mm it's quite long for a rim-braked bike. It certainly gives you a feeling of confidence in the bends.
The frame of the Agree is quite aggressive, with plenty of boxy sections rather than more traditional tube shapes, and it follows the common theme of oversized at the front end and along the bottom for handling and power transfer, while going a little skinner elsewhere for some comfort.
The head tube houses a tapered headset and corresponding fork steerer, which gives a larger cross sectional area to attach the bulky down tube. The fork crown is also shaped to blend in with the down tube for aerodynamics.
Cube has gone for a press-fit bottom bracket, which won't appeal to everyone but this allows for a wider BB shell for added stiffness and gives more material to attach the chainstays and down tube to.
Cube has also kept the seatstays lower down the seat tube, which creates a smaller triangle for increased stiffness at the rear end.
Even though this isn't a race bike, Cube has focused on a small amount of aerodynamics and one way it says it's done this is by using an integrated seat clamp rather than having the usual bolt-on method.
As you can see from the photos, the Agree uses fully internal cable routing, making it compatible with both mechanical and electronic groupsets. My only criticism is with the setup of the rear brake cable, which my thigh rubbed on every pedal revolution, but if it was my own bike it'd be easy to rectify.
This Agree is yet another bike that we've received with a new Shimano Ultegra R8000 groupset on, and it is absolutely awesome.
Its predecessor, 6800, was far from shoddy but this latest version delivers a slightly crisper, more defined shift as a result of the tweaked mech designs, and the shifters are a joy to use and ride on.
To match its endurance credentials, the Cube comes with a 50/34t compact chainset and an 11-32 cassette that's actually from the 105 parts bin rather than Ultegra.
This gives a good range of gears, especially for climbing, with the 50x11 giving you plenty of top end for those fast descents.
Cube has designed this frame to accept direct mount brakes rather than the more usual single mount dual pivot design. If you haven't seen them before, direct mount brakes have two fixing points drilled and threaded into the frame and fork to attach the callipers to. This gives a firmer fixing with no chance of any sideways play; you can notice a slight benefit in braking performance too.
Cube provides all of the components – handlebar, stem and seatpost – which all do a decent job and match the look of the frame.
The handlebar has a compact shallow drop which, when paired with the 170mm head tube, gives a less aggressive position if you want to hunker down on the bottom of the bar.
All the components are plenty stiff enough without battering you about too much either.
While the Selle Royal Asphalt saddle looks way more padded than I'd normally use, I actually got on with it well. The padding is firm not bouncy and it didn't cause any pressure points even on longer rides.
Mavic's Cosmic Elite wheels are a solid set of all-rounders. At around 1,770g they aren't the lightest, but they certainly don't feel especially weighty and still accelerate and climb well, with a 30mm deep rim and aero spokes.
If you want to really push the pace I'd say an upgrade would be on the cards, but straight out of the box and for the majority of riding I'd say they are just fine (and the matching graphics look cool too).
Throughout testing they threw up no problems at all in some difficult conditions. Loads of water and grit never saw an issue with grumbling bearings or freehubs.
Rather than supply Mavic's own brand tyres, Cube has gone with Continental's Grand Sport Race in a 700 x 25 size (though the spec says 28s). They aren't quite up there with, say, the Conti GP4000s in terms of grip and performance but they are very good tyres in their own right. I had plenty of confidence in them when cornering in the wet or dry, and had no problems with punctures or durability.
When it comes to the money, Cube's RRP of £2,099.99 does look a little pricey against some of the other bikes we've tested with similar characteristics.
One bike the Agree reminds me of is the Boardman SLR Endurance Disc 9.0 which cost £1,999.99. That one obviously has disc brakes, and the closest rim-braked model on Boardman's books is the FSA/Dura-Ace equipped Endurance 9.2, with an RRP of £2,099.99 – the same as the Cube.
Now few brands can compete with Canyon on pricing, and there is no way we could forget to mention its Endurace model. Tass rode the WMN CF 9.0 Di2 (a unisex model with women-specific touches) which sounds a near-identical bike to the Agree C:62: racy but with that endurance geometry. An Ultegra-equipped, Conti-tyred Endurace CF 8.0 will set you back just £1,749 excluding shipping – very impressive indeed.
On the whole I reckon the Cube Agree C:62 Pro really nails it as a fast bike for the non-racers. At its heart is an awesome frameset which really feels alive and just wants to be ridden hard. Upgrade the wheels to drop the weight and this thing will fly.
An endurance bike with a very sporty bias, the perfect balance between speed and a less extreme riding position

Tell us what the bike is for
Cube says, "When we sat down to design the Agree C:62 Pro, we had one goal in mind: to set a new benchmark in the endurance race bike category. Riding long and hard on a bike that responds to your every whim is what it's all about. High tech carbon frame construction, incredible attention to detail and CUBE's fastidious in-house testing mean you can be assured of an exceptional ride. But this level of performance needn't break the bank. With brand new Shimano Ultegra components for slick shifting and powerful braking, a light and strong Mavic wheelset and a frame that's both incredibly stiff and surprisingly comfortable, pro level performance is now within any rider's reach."
Frame and fork
Tell us about the build quality and finish of the frame and fork?
The Agree has a well made and finished frameset which is also a joy to ride.
Tell us about the materials used in the frame and fork?
Both the frame and fork are made from carbon fibre which Cube doesn't divulge the brand or grade of in the bike's specification.
Tell us about the geometry of the frame and fork?
The Agree is an endurance bike but things are still quite racy with a mix of pretty steep angles and such things as the extended wheelbase.
How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?
The 56cm has a reach of 390mm and a stack of 573mm, which gives an overall ratio of 1.47 – racy for an endurance bike, and it rides like it.
Riding the bike
Was the bike comfortable to ride? Tell us how you felt about the ride quality.
It is a firm ride for an endurance bike, but I wouldn't call it uncomfortable.
Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?
Yes, this is a bike that likes to be ridden hard and its stiffness reflects that.
How did the bike transfer power? Did it feel efficient?
Really well, it feels more like a race frame.
Was there any toe-clip overlap with the front wheel? If so
How would you describe the steering? Was it lively Yes, it's lively.
Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?
Considering the geometry, the Agree really rides as much like a race machine as an endurance bike, which shows that Cube has managed to hit the brief.
Which components had the most effect (good or bad) on the bike's comfort? would you recommend any changes?
The frame takes out a lot of the harshness, helped by the saddle and, to a degree, the Mavic wheels.
Which components had the most effect (good or bad) on the bike's stiffness? would you recommend any changes?
The aluminium components from Cube are a welcome addition to the Agree's frame, as they keep the whole bike a really tight, stiff package.
Which components had the most effect (good or bad) on the bike's efficiency? would you recommend any changes?
Those Mavic Cosmics are great here; you get a small aero advantage plus they are quick rolling and offer consistent braking.
Tell us some more about the drivetrain. Anything you particularly did or didn't like? Any components which didn't work well together?
Shimano's latest Ulegra offering is an awesome groupset. It has sharper shifting than its predecessor, which to be honest was pretty good in the first place.
Wheels and tyres
Tell us some more about the wheels.Did they work well in the conditions you encountered? Would you change the wheels? If so
At a claimed 1,770g a pair the Cosmics aren't the lightest wheels on the market but they suit the Cube well. An upgrade to something lighter or more aero would benefit the bike, but it isn't a must straight away.
Tell us some more about the tyres. Did they work well in the conditions you encountered? Would you change the tyres? If so
The Continental Grand Sport Race tyres are decent all-rounders, filling that middle ground between performance and durability. I found the grip levels to be good in the wet and dry, inspiring plenty of confidence.
Tell us some more about the controls. Any particularly good or bad components? How would the controls work for larger or smaller riders?
The Cube finishing kit works well with the bike and I certainly wouldn't be in a rush to change anything.
Did you enjoy riding the bike? Yes
Would you consider buying the bike? Yes
Would you recommend the bike to a friend? Yes
Use this box to explain your overall score
The Agree blurs the lines between a race bike and an endurance machine with sporty performance coupled with the less extreme ride position. At its heart is a great frame, which is fitted with some very good components to create an impressive package. It will also respond very well should you feel like upgrading.
