Cube Gravel Bikes

Decoding the Cube Gravel Lineup

The Nuroad range reads like a menu once you know the code. At the base, you've got the Nuroad Pro - HPA aluminium frame, entry-level Shimano GRX or Tiagra gearing, and a full carbon fork for vibration damping. Solid starting point. Move up to the Nuroad EX and the key shift is the drivetrain: Cube Nuroad vs Nuroad EX basically comes down to 2x versus 1x. The EX runs a single-ring setup optimised for rougher, looser riding where simplicity and mud clearance around the chainset matter more than having a bailout small ring for long tarmac drags. The Nuroad Race steps back to a 2x groupset but with higher-tier components - more range, finer gradations between gears, better suited to mixed-surface riding where you're covering real road mileage too. At the top sits the Nuroad SLT, the flagship build with top-shelf groupset spec and the finest finishing kit. Then there's the carbon side of the house. The Cube Nuroad C:62 uses Cube's own C:62 carbon layup across frame and fork, and it's a meaningfully different ride feel - sharper, quieter over rough stuff, and lighter on your back on longer days. If you're doing multi-day routes, that weight saving compounds. Looking at Cube road bikes as well? Worth comparing geometry if you're on the fence about which direction suits you best. And again, if the appeal is motor assistance for loaded touring or hilly commutes, the Nuroad Hybrid range lives on our Cube E-Bikes page.

The Tech Behind the Frame

Cube's C:62 and C:68X Advanced Twin Mold carbon technology is worth understanding rather than just nodding at. The C:62 designation refers to a layup ratio of 62% carbon fibre to 38% resin. That balance keeps the frame from being brittle - higher resin content than some aggressive race layups, which matters on abrasive surfaces like the flinty chalk of the South Downs or the loose grit of a Pennine bridleway where a frame takes knocks. It's not the outright stiffest carbon you'll find at this price, but it's deliberately tuned for durability alongside weight savings. Think of it less as a track weapon, more as a long-haul tool that won't rattle your fillings out. The C:68X is Cube's next tier up - a more aggressive, stiffer layup used on their higher-end builds where stiffness-to-weight is the priority.

Gravel Comfort Geometry is the other piece of the puzzle. Cube stretches the wheelbase slightly compared to their road race bikes and raises the head tube just enough to give you a more upright position on loose descents. The result is a bike that doesn't demand constant micro-corrections on rough ground - it tracks more predictably. You still get a lively, responsive feel on tarmac, but it's not trying to be a race bike. On fast, technical descents - the kind you get dropping off the Ridgeway or into a Welsh valley - that stability is genuinely reassuring rather than something you only notice in a press release. Full carbon forks feature across the Nuroad range, alloy and carbon alike, and they do meaningful work absorbing vibration from chip-and-tar roads and compacted gravel. Internal cable routing keeps things tidy and protects cables from the grit and grime that comes with year-round UK riding.

Living with a Cube Nuroad in the UK

Tyre clearance is the practical number that matters most for British gravel riding, and modern Cube Nuroads clear up to 45mm without mudguards. That's enough room to run a proper winter tyre - something with enough volume to float over peanut-butter mud rather than punch through it. Fit full-length mudguards and you're looking at around 40mm, still generous. The hidden mudguard and pannier rack mounts are a quietly significant feature - this isn't just a fair-weather machine. Load it up with a rack and guards in October and it becomes a genuinely capable commuter and tourer without looking like a compromise. For bikepacking setups, multiple bikepacking mounts across the frame mean you can add a frame bag and bar bag without resorting to aftermarket bodges.

One thing worth knowing before you order: Cube bikes traditionally run a touch short in reach compared to brands like Canyon or Giant at equivalent nominal sizes. If you're between sizes, check the geometry chart rather than going on your usual size - a longer stem or a size up may suit you better if you prefer a stretched-out position. It's not a flaw, just a characteristic to factor in. Riders coming from more compact geometries often find Cube's fit slots in immediately; those used to longer front centres may need to fiddle with stem length. Either way, get the geometry chart open before you click buy. The flat mount disc brakes and Shimano GRX drivetrains throughout the range are both well-supported for servicing in the UK, which matters more than people admit when you're standing in a muddy car park in February with a cable that's given up.
