Train with power for efficiency and effectiveness, and you'll be battering your way up climbs and speeding along flats before you know it. Power meters are the most effective way to get there, but they can be pricey. Happily, there are a bundle of discounts to be hand, whether you want power meter cranks, pedals or hubs.

SRAM Red Quarq PowerMeter 53/39 Tooth Double BB30 Crankset
If you're looking for a power meter that will go the distance, we rated the SRAM Red Quarq Power Meter as 'simple and robust', and it's a fully integrated system. ANT+ compatibility means you can pair it up with smart devices to monitor your output as you ride, and the fact it's integrated means fewer physical connections exposed to the elements.
Stages Power Meter – Shimano XTR M985
Simple, light and relatively inexpensive - well, at least a far as power meters go - the Stages Power Meter plus Shimano XTR M985 is a replaceable left hand crank unit. It measure cadence, power and acceleration, and communicates with ANT+ and Bluetooth Smart devices - so you can upload your details straight to Strava via your iPhone.
CatEye Stealth 50 GPS computer
Once you have a power meter, you'll need a way of monitoring its output as you ride. Enter the CatEye Stealth 50 GPS computer, which currently has a 26 percent discount at Hargroves Cycles. We checked out an earlier version of this computer in 2013.
It's ANT+ compatible, which will allow you to sync it up with cadence, heart rate, speed and power sensors, has (as the name suggests) GPS logging to record your route, plus the usual elements such as time, distance covered, odometer, and speed measurements.
Stages Power Meter – Ultegra 6700
This setup gets you a Stages Power Meter with Ultegra 6700 crank, a popular and robust option for road cyclists. For just shy of £460 you get a left-hand crank fitted with a Stages Power Meter.
Connect it up to an ANT+ enabled device (like the CatEye Stealth 50 above) and you can monitor your power output as you pedal along. The meter also links with Bluetooth devices.
Powertap Powercal Strap & Speed/cadence Sensor Bluetooth
Using a cadence sensor and heart rate monitor, the Powertap Powercal determines your power output using your heart rate. While it might not be quite as precise as other power meters (by Powertap's own admission) it is simple to use and far, far cheaper. It's also Bluetooth compatible so will work with your Bluetooth enabled devices such as smartphones and cycling computers.
CycleOps Fluid 2 Power Training Kit
The Fluid 2 trainer got a full five stars when we reviewed it on BikeRadar, and with the Power Training Kit you get the trainer plus the PowerTap PowerCal Power Meter and Joule cycling computer – everything you need to train with power from the comfort of your own pain cave.
Garmin Vector Pedal Based Power Meter – Keo Compatible
Harness Garmin to help you train and race with power, with these Garmin Vector power meter pedals. The pedals automatically recalibrate when fitted to a new bike, so you can switch them easily between steeds. There's an integrated cadence sensor and strain gauge, and ANT+ compatible so you can pair them up with suitable computer units, although Garmin do recommend the Edge 510 and 810.
We did a long term test of the Garmin Vector pedal power meter a while back, and it impressed us, citing that it's "ease of use, plus accuracy and wealth of data justify switching pedals".
PowerTap G3 rear hub
Fancy a hub-based power meter? Then PowerTap has you covered – the G3 weighs in at a claimed 325g and is very accurate. It's compatible with Campagnolo, Shimano and SRAM and uses a CR2032 battery for power.
