GARMIN RALLY XC 200 £1,059.99

If you’re really serious about training or racing, knowing how many watts those legs put out on the bike is the most accurate and effective way to train. Until now, you’ve had to be modestly handy with the spanners to get going with power, though, fitting a dedicated drivetrain with its sensor wizardry buried inside. The new Rally XC 200 clipless pedals do away with much of the faff; all you have to do is wind them onto your bike like normal, sync with your Garmin computer, and await the datablast of information they’ll send you.

The strain gauges are buried inside the spindle of the pedals, the idea being you can swap that into a pedal body for your road bike without having to buy a separate pair or a regular power meter. The Rally XC

200 will record data for a claimed 120 hours before needing a new LR44 button battery. It’s waterproof, accurate to plus or minus one per cent and the pedal should function just like a regular Shimano SPD. At over £1,000, it’s an expensive option, though, especially when you work out you can get a left-crank-arm power meter for around £350 from the likes of Stages, Quarq (SRAM), or 4iiii.
