Blackburn Atom 4.0

Opinions on the aesthetic values of the Blackburn’s head unit were divided but it’s certainly not the least attractive computer on test (the Union definitely takes that prize). The speed sensor is a beast, though, and although the fin styling is a nod to sleek lines, it could definitely do with losing some bulk. Mounting […]

Pro SX4-W Wireless

There are plenty of people who’ll argue that you only need the seven simple functions on offer from the Pro SX4-W. And we know plenty of triathletes with high-end power meters and computers suffering from chronic paralysis by analysis who could do well to heed this advice. The neat head unit looks really classy and […]

Cateye Velo 8

On its own in the bargain basement, the Cateye Velo is a no-frills, old-skool wired bike computer. In these modern days of wireless and GPS fitting it evokes a touch of nostalgia, but apart from having to neatly route the wire it’s a simple zip-tie job. And we genuinely do think that there’s still a […]

Union 9WN

Both the packaging and head unit of the Union look a bit dated. The head unit in particular has a distinctly 1980s vibe and, while that may have a certain retro appeal, you wouldn’t put it on your P4. Its nine functions tick all the important boxes but there’s nothing so special that you’d overlook […]

Knog Nerd 12

Our tester let out a sigh of relief as he unpacked the Knog. Without a zip tie or rubber band in sight, installation is a genuine fiddle-free thirty-second job. Combine this with the two-bike memory and the Knog is perfect for dual-bike use. This tester happily swapped it back and forwards from his road to […]

Cateye Strada Wireless

Stylish, compact and in a range of colours, the understated head unit exudes minimalist class and the eight functions it offers are a solid no-nonsense affair. No bells and whistles but nothing superfluous, either. The sleek sensor mounts easily with a couple of zip ties but, although the jubilee clip fitting mount is easy to […]

Boardman 22 Function

Setting up and installing the Boardman is a breeze. The neat, if slightly boxy, speed and cadence sensors zip tie on, and the head unit mount attaches to either stem or bars with a simple but effective rubber band system. The head unit isn’t exactly a looker but the display and unit size are good. […]

Sigma BC 1609 STS Cadence

In the looks department the Sigma is head and shoulders above the competition. Both the speed and cadence sensors have a stealthy mean appearance, and the head unit looks genuinely cool and wouldn’t look out of place on a carbon mega bike. The sensors fit easily with a couple of zip ties, and the head […]

Topeak Panoram V10c

Delivering both speed and cadence for under £65, the Topeak gets off to a good start. But once you begin installation, you quickly fall out of love. The wireless cadence sensor is neat enough and a simple zip tie affair, but that’s as good as it gets. A wired speed sensor really belongs on a […]

Polar CS100B

Coming from the pioneers of heart rate monitoring, the Polar computer has a lot to live up to. All the key functions are present, and offering heart rate compatibility at this price is excellent. Although you don’t get a chest strap with the package, it seems most triathletes have a Polar strap knocking about somewhere. […]

Cateye Adventure

Apart from the regular features you’d expect in a standard bike computer, the Adventure adds an altimeter, slope indicator and thermometer to the mix. The altimeter, which works using barometric pressure, is accurate as long as you calibrate it regularly to known points or use the ‘Home’ function. If you live and ride in a […]

VDO X1DW

Setting up and using the X1 DW is as easy as any wireless bike computer. But, judging by the process outlined in the two instruction booklets, you might think it was actually some sort of aptitude test. First you must work out what each of the four buttons on the main unit – up, down, […]

CatEye Micro Wireless CC-MC100W

Thank God for wireless technology. It’s made setting up bike computers a dream. Two pairs of zip-ties, some sticky-back plastic (provided), and about five minutes was all it took to get CatEye’s Micro Wireless up and running. Operation is equally straightforward, with one start/stop button (though this would benefit from a more positive feel) and […]

Sigma Rox 9.0

On paper this is the mother of all cycle computers. As well as the usual parameters (wireless cadence, speed, distance), it measures heart rate, temperature, altitude, gradient, total ascent/descent and can probably predict what your mum’s cooking for dinner. It interfaces with a PC via a USB connection and software supplied for ‘easy’ analysis. In […]

Cateye V3

Nobody has a better reputation for computer reliability than Cateye, but visibility and versatility could be better. While the rack-and-pinion thumbwheel attachment strip is very clever, it’s a lot bulkier than zip ties and can’t cope with flat wing-style bars. The combined cadence and speed sensor makes for easy set-up and rear-wheel turbo compatibility. The […]

Sigma BC2006 MHR

Sigma has always had a solid reputation for decent easy-to-use computers and this full-function squarehead is no exception. Paying nearly £100 gets you chrome sidestripes and crisp detailing all round, as well as a massive book of instructions. ‘O’ ring installation is easy and repeatable on different bikes without the need for extra zip ties.

Pro Scio W4.1

The Pro range is basically Shimano’s set of accessories, and this computer was a joy to use. The head-unit twist locks into a thin, but perfectly secure stem- or bar-mount cradle that’ll flatten to fit onto wing bars. HR belt is a bit broad, stiff and basic, but it registered reliably from the first lick […]

Ciclosport CM8.3AM

Ciclosport has a big European presence and Lance Armstrong was a long-time user, but this computer needs several add-ons to compete on functions. Having to pay £32.99 extra for the heart-rate belt and £24.99 for the cadence sensor is the sting, especially as the software and USB stick that you need to work with the […]

Garmin Edge 705

If you want cutting-edge computing power then you have to look at Garmin’s latest GPS-enabled baby. First thing you’ll realise is that this is a big piece of kit even compared to the old 305. However, while it definitely takes up a lot of space on the bars, it sits on top of a stem […]
