At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The £999 Mares AX 3.0 from German company Focus combines a smart aluminium frame with a carbon fibre fork and their innovative easy-to-use thru-axles to offer a good all-rounder or first bike for someone looking to get into cyclo-cross racing.

The 50/34 compact chainset along with rack mounts points to a bike that is better suited to daily commuting than regular off-road excursion, a compromise that will appeal to some potential customers more than others.

Performance

The Mares AX 3.0 is a fun bike to ride. The geometry is well suited to the demands of cyclo-cross racing and it's also at home exploring the trails away from the hectic nature of a 'cross race. It's a fine tarmac chugger too, though for longer jaunts you'll probably want to swap for some slicker or more closely treaded tyres.

It's not that light and you do notice the weight when getting the bike up to speed off-road; you get good at maintaining momentum through the corners. The weight does provide good stability over rough ground and when bouncing over roots and rocks. It's not a bike you'll want to be shouldering too often though unless you've got a strong back.

The weight is a handicap if you're looking to race, but it's not so heavy that you won't still finish a 'cross race with a huge smile across your face. If you're aiming to do the occasional 'cross race for fun then the weight isn't a problem - I was able to finish in a respectable position when I raced the Focus.

The disc brakes are the most appealing aspect of the bike. The mechanical disc brakes are very positive in use with single finger braking providing plenty of stopping power with none of the fork judder of a cantilever setup.

While they don't have the outright power of a hydraulic setup, there is more than enough power for the slower speeds involved in cyclo-cross. Critically, once you get used to great stopping ability of the disc brakes, you'll find it really difficult to go back to a 'cross bike with canti brakes. It's a world of difference.

Handling is pleasingly direct and the steering feels sharp and responsive. It's a stiff bike and does relay a lot of vibration through to the contact points though, so it's not the most comfortable over harsh terrain. Careful setup of tyre pressure is required to dampen vibrations on rougher courses.

Frame and fork

The Mares AX 3.0 features a frame made from triple butted aluminium with a carbon fibre fork. All cables are routed internally, the gear cables entering the down tube and the rear brake entering the head tube. The front brake cable is routed externally along the rear edge of the carbon fork.

There is an externally threaded bottom bracket which offers easy serviceability, a good choice for a bike designed to be ridden through deep puddles and mud, it'll be easy to change when it needs replacing.

There are two bottle mounts and there are rack mounts on the frame, making it a good option for daily commuting if you wanted.

The most interesting aspect of the frame and fork are the axles. Gone are regular quick release axles and in their place the company's own and unique RAT (Rapid Axle Technology) thru-axles. They are extremely simple to operate, and much quicker than a regular quick release.

To remove the wheel, you simply open the lever, twist it 90 degrees, and slide it out. It's that easy. It takes a couple of goes before you get the hang of it, but once you do the action is pleasingly quick.

The axles provide very secure wheel attachment and the 15mm front axle diameter does appear to increase the front-end stiffness. Under heavy braking or pushing hard on the handlebars during out of saddle sprints, there's very little twist or flex, and no brake rub.

There is stacks of mud clearance around the tyres at both the fork and rear triangle and I never encountered any issues with clogging even riding through some very boggy trails.

Build

Focus have spent the money wisely on the Mares AX 3.0, with decent Schwable Rocket Ron tyres a highlight. They're a good tyre for most conditions, reasonably faster on harder terrain and tarmac and enough grip for all but the sloppiest conditions. The amber sidewalls look the part too, though could be tricky to keep that way through a muddy winter.

Concept EX is a Focus own-brand label, and finds its way onto the deep-section aluminium clincher wheels, stem, handlebar, saddle and seatpost. It's all good quality kit with the saddle a comfortable shape and the handlebars providing a nice shape and reach. The wheels aren't the lightest option but are very strong and stand up to some rough riding over rocks.

Shimano's R517 mechanical disc brakes are 105 level and feature independently adjustable right and left pad clearance. That means they'll provide good disc clearance as they wear out. They calipers use a forged one-piece design to boost stiffness.

The brakes are controlled by Shimano Tiagra brake levers, which also operate the Tiagra front mech and upgraded 105 rear mech. The compact 50/34 Tiagra chainset is fine on the road and so a good choice if you're looking to use the Mares for regular commuting, but for riding off-road and competing in cyclo-cross races it's simply too big; a 46/36 chainset would be better. There is a 12-28 cassette fitted to the rear wheel.

Conclusion

A competent cyclo-cross bike that is well geared for riding on the road but needs a chainset swap for regular off-road riding and cyclo-cross racing. The weight is a handicap for racing but the disc brakes provide fantastic control and precise speed adjustment. There's plenty of upgrade potential in the Mares and it's a good starting bike if you're new to cyclo-cross.

Verdict

Decent performance and impressive disc brakes make for a good all-rounder and first cyclo-cross bike

Anything further to say about the bike in conclusion?

A good first cycle-cross bike ideal for much more than simply 'cross racing, but really needs a lower ratio chainset for regular off-road riding. The mechanical disc brakes and the RAT thru-axles are a real highlight of the bike and help it stand out among all the other options at this price.

Thinking of getting the AX 4.0 as a winter bike/commuter. Is there any reason why I'd go for the 3.0 for the extra £150? The specs are almost identical (3.0 gets a carbon fork and a few tiny upgrades like a 105 rear derailleur), but then the 4.0 has mudguards and a light already fitted.

Can front mudguards even be fitted to the 3.0?

I reckon the reason the 4.0 has a different fork is because it has mounts. The fork on the 3.0 doesn't look to have them. Sure, you can use clip on guards at the hub end but without a drilled hole at the crown, fitting guards is near impossible.

This makes the 3.0 unsuitable as a winter bike IMO, buy the 4.0.

Will there also be a review of the AX 1.0?

I'd be interested to know if the hydraulic disc brakes and other improvements are seen as a worthwhile upgrade.

I think that these bikes will see much more action as fast commuters than racers. It seems to have mudguard mounts at the rear, would it take 'guards at the front?
The fork crown isn't drilled at the front and there are no eyelets at the fork so unless they're well hidden it looks unlikely. But it seems unlike Focus to do half a job, so I wonder if there's a clever mount?
