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.

Specialized's Crux Elite is a simply brilliant cyclo-cross bike that provides really good handling, bags of pace and all the benefits that disc brakes bring to the party, all wrapped up in a bold looking package. It's ready to race, but is equally at home blasting along bridleways and through the local woods for a couple of hours.

Specialized Crux Elite X1

Frame and equipment

For 2016 Specialized UK is only bringing in a select number of the full Crux range, and it has clearly decided the majority of new customers for cyclo-cross bikes will want disc brakes, as the four models all sport them. At £2,500 the Crux Elite X1 is the most expensive build, and combines a FACT 10r carbon fibre frame and fork with a SRAM Rival 1 drivetrain and hydraulic disc brakes, with a full house of Specialized branded componentry.

What the Crux isn't is a versatile do-everything cyclo-cross bike. It's a race-focused bike. With the gravel/adventure category coming along in the last two years, Specialized has developed the Diverge, a bike intended to appeal to that cyclist seeking the big tyres and capability of a cyclo-crosser, but wrapped in a more suitable package, with plenty of rack, mudguard and water bottle mounts.

That leaves the Crux with a clearer purpose of intention. While mudguard and rack mounts are shunned, it retains two bottle cage mounts. It's ready to race, out of the box, but there's nothing to stop you sticking two bottles on and riding it all day on a variety of roads and paths. But it's most likely anyone buying the Crux is going to be looking at racing it.

Specialized Crux Elite X1- down tube

The FACT 10r carbon fibre frame and fork are disc brake-specific. Specialized has used bolt-thru axles, which add extra stiffness and provide reassuring wheel security. There is currently no 'standard' thru-axle, though; Specialized has used a 100 x 12mm at the front and a 135 x 12mm out back. 

That raises wheel compatibility concerns and makes it virtually impossible to source an aftermarket wheelset for this bike. It's a real shame Specialized didn't adopt the much more common 142 x 12mm rear axle standard as that would have provided the potential customer with a lot more wheel choice, and the option to use a 29er mountain bike wheelset in the bike. 

Wheel compatibility will be a bigger concern for hardcore cyclo-cross racers who might want to have a fleet of spare wheels with different tyres, but probably less of an issue for the privateer racer. Even if you're not worried about having multiple wheelsets, it does limit the future upgrade potential. A real shame. 

Specialized Crux Elite X1- front axle

It's clear that despite the slow uptake of disc brakes on the professional cyclo-cross circuit, amateur 'cross racers and those new to the sport have been swayed by disc brakes. The handful of cyclo-cross races I've done recently offer enough evidence that disc brakes are in the ascendancy, particularly with people racing for fun and less worried about actually winning.

Tyre clearance is generous. There is tons of space around the 33mm tyres fitted, so going wider wouldn't be a problem and negates any worries about clogging on muddy courses.

Specialized Crux Elite X1- seat stays

Although this bike has no front derailleur there is a redundant front derailleur hanger, which is a bit of an eyesore and a missed opportunity to clean up the lines. There's also a redundant cable port on the down tube, but then this frame is used across a wide number of builds with regular drivetrains.

A full sweep of Specialized branded equipment is used for all the contact points. It's all good, solid stuff, if not particularly exciting in appearance. You get a 27.2mm aluminium seatpost and a 42cm-wide aluminium handlebar and 10cm stem on the size 56cm bike. The Romin saddle is a definite highlight, comfortable and firm. You could save a bit of weight with some carbon fibre parts, but at 8.8kg (19.4lb) for this 56cm bike it can hardly be labelled as heavy.

Specialized Crux Elite X1- saddle

The Axis 4.0 Disc SCS wheels are Specialized's own product. The understated appearance hides a tubeless-ready rim with Centerlock compatible hubs. The wheels are a reasonable weight, at 1,625g, and stiffness is pretty good, but after three races the spokes in the rear wheel needed tightening, as they had loosened and were creaking a lot under power.

The Terra Pro tyres carry Specialized's tubeless-ready label, 2Bliss, so going tubeless would seem a sensible thing to do. So that's what I did after the first ride. The Terra Pros provide good grip on a range of surfaces and terrain, with good rolling resistance, though cornering traction could be enhanced with more aggressive shoulder blocks.

Specialized Crux Elite X1- tyre

Going tubeless was easy. I simply removed the inner tubes, added a layer of Gorilla Tape, inserted a tubeless valve and a slug of sealant, and had the tyres inflated using just a track pump. I've done four races so far and the setup has been great, but all the races I've done have been dry, so I've not had to run low pressures. At around 30psi, though, I've not experienced any excessive tyre roll or burping (when the tyre momentarily breaks the tubeless seal with the rim and leaks sealant).

Most serious cyclo-cross racers are wedded to traditional tubular tyres, because you can run them at very low pressures and because of the weight benefits they offer. It's still early days for tubeless in cyclo-cross; there isn't a lot of tyre choice, but I can foresee a lot more amateur and privateer racers running tubeless in the future. It massively reduces the risk of puncturing and allows you to run lower pressures than you would want to with a clincher and inner tube setup.

Gearing – single ring simplicity

SRAM's new Rival 1 groupset ditches the front mech and combines a single ring, with specially shaped wide/narrow teeth to provide increased chain retention, with a wide-range 11-speed cassette. This bike pairs an 11-36t cassette with a 40t chainring. The bulky rear derailleur owes its appearance to a clutch mechanism inside that prevents chain slap over rough ground and minimises the chain dropping off the chainring.

Specialized Crux Elite X1- rear mech

The beauty of the drivetrain is the simplicity of use. Just one gear paddle using SRAM's DoubleTap concept moves the chain quickly across the cassette. It's a bit clunky; it doesn't have the lightness of a Shimano setup, but that's actually a benefit when riding off-road or in the red mist of a cyclo-cross race – you're left in no doubt that a gear change has occurred.

Specialized Crux Elite X1- shifter

I've found the spread of gears very usable, enough for steep hills, and the ratios close enough together to never really find myself in completely the wrong sprocket. Because there's just the one chainring, I'm always near the right gear, whether approaching a climb or descent, and moving from one extreme to another is a quick process – none of that double shifting you have to do with two chainrings.

And so far, touch wood, I've not dropped a chain. I've not yet had a truly muddy race or ride to put the groupset through, but it has shown good signs of clearing easily on some of the mud that I have encountered this autumn. I'll update this review should any issues arise in the mud. And I will just say that I have been using SRAM's 1x11 drivetrain on a mountain bike for the past couple of winters and never had any issues.

Braking power

Head to any local or regional cyclo-cross race and you'll see a lot of people on disc brake-equipped cyclo-cross bikes. Disc brakes are growing in popularity, despite a reluctance by most of the top world cup cyclo-cross racers to switch wholesale to them.

I can appreciate why the top level racers haven't adopted disc brakes, yet – the weight for starters – but away from the top ranks, amateur/privateer/have-a-go racers are clearly leaning towards them. Why? Well, personally I've found that disc brakes simply offer better and easier ability to control speed, whether it's minute adjustments through a fast, sweeping turn, or stopping abruptly for a tight hairpin. For me, the improved control outweighs the weight penalty.

The SRAM brakes are smooth and progressive with nice levers, and they're easy to reach whether in the drops or hoods. The large hoods aren't pretty, but they do provide good places to anchor your hands when descending or riding over rough ground.

Ride and handling

In the cut and thrust of a cyclo-cross race, the Crux is fast, stable and poised. The brakes inspire confidence – being able to brake late and hard into corners is addictive, and gentle adjustments for scrubbing speed through faster turns is a delight. The frame and fork show a high level of stiffness, allowing you to really muscle the bike through corners and over bumps and rocks, with no discernible flex or vagueness when climbing or sprinting out of the saddle.

The handling definitely leans more towards stability than agility, though. It can be a bit of a handful through a succession of really tight corners, but when the course opens up and the speed increases, the Crux really lights up, and you can gain back time lost through the tight stuff. The positive in its handling is how friendly it is if you're new to cyclo-cross; it's an easy bike to ride fast and deals with bumpy terrain extremely well.

The Crux won't win a weight contest, but on a flat and fast cyclo-cross course with a few short ramps, I haven't found its 8.8kg (19.4lb) a penalty at all. Yes it's heavier than a similarly specced cantilever version, but unless you're obsessed with weight it's not a deal-breaker. The Crux certainly feels fast. It accelerates out of corners swiftly, with the stiffness of the whole bike providing a reassuring snap as you get the power down.

The contact points all fall to place nicely, with the handlebar a good shape, the shallow drops not requiring superb flexibility. The bigger SRAM hoods might not be aesthetically pleasing, but on rufty tufty terrain they do provide a good place to firmly anchor your hands. And because the hydraulic brakes are so powerful, you can operate the levers from the hoods with a single finger.

Specialized Crux Elite X1- stem and spacers

Away from the confines of the course tape, the Crux is right at home on mixed terrain rides. The more-stable-than-agile handling is a bonus on faster and rougher tracks, where you're not sure what is around the next tree. And on the road it's fast, the tyres providing reasonably good rolling resistance so your pace isn't impeded too significantly.

On a variety of rooty singletrack in my local woods and knitting together bridleways, gravel paths and farm tracks, the Crux is fast paced and rarely gets out of its depth, provided you don't try to ride it like a fully suspended mountain bike on your favourite descent... If you want to explore local trails away from the busy roads but don't want to go down the mountain bike route, a cyclo-cross bike is a perfect way to mix it up and inject a bit of fun into your riding.

Conclusion

The Crux is a simply brilliant cyclo-cross bike that is ready to race but equally at home off the beaten path on longer adventure rides. Wheel compatibility issues will be a deal-breaker for some, but if you can overlook that  and want a really sorted bike to race and ride through the winter, the Crux Elite X1 should be right near the top of your list.

Verdict

A brilliant cyclo-cross bike that is fast and fun to ride and ideal for racing

Looks great, but hard to know who this is aimed at. Price tag says serious racer, but the wheel situation will put most of them off. Disc brakes are definitely getting popular on the front of the starting grids, but not tubeless. Tubulars definitely rule the roost for the quickest riders.

Awesome bike for sure, but how can it get 4.5 stars and a 9/10 with the wheel problem!?

 

Totally bonkers decision by Specialized, and causing a lot of grief for riders, and even shop teams who ordered  these to race on. There are no aftermarket wheels or hubs that fit, and you can't even order a spare set of the stock wheels as Specialized say they won't have any in stock until late November. When the CX season is mostly over.

That's Specialized all over though - try & change things and end up shooting themselves in the foot with it!  See their stupid narrow OSBB on their carbon Tarmac frames and bizarre headset bearing sizes for starters.  Specialized; just keep things normal!

Nice, reasonably priced as well! Not 'identical', but interesting the color scheme is so close to my 15' Lapierre Pulsium Ultimate. Not a bad thing, I just had to do a double take when I first saw this review.
