Drivin forces Power, information and friction-reducing bearings

LezyneMegaXLGPS £180

The Mega XL takes its name from its big 2.7in 240x400 display, which you can use in portrait and landscape orientations. You can also pair the device with your smartphone for texts and call alerts, download route maps and sync it to Strava and Training Peaks using Bluetooth Smart or ANT+. Oodles of customisation round out the package.

StagesDura-AceLR powermeter£1199

The latest Dura-Acecompatible Stages has a claimed +/-1.5 per cent accuracy, measures cadences between 20-220rpm and power up to 2500 Watts (plenty for most people), and transmits all this info to most head units via ANT+ or Bluetooth.

Ceramic SpeedOSPW mechcage £399

Marginal gains, eh? You might think that this is about as marginal as it gets, but the ceramic bearings in this mech cage’s jockey wheels seemingly spin forever. Ceramic Speed claims that this mech cage can reduce friction in your drivetrain by 30-60 per cent.

Ceramic Speed bottom bracket from £269

Ceramic Speed bottom brackets are available for just about every standard out there. What they all have in common is that claim to be able to provide with the lowest friction for optimised power transfer and longest product lifetime. Any *,/"!"#" &"+1!#+!!6,2! won’t need to pedal, maybe…

Specialized Left-Hand Power Crank£650

Specialized partnered with power specialist 4iiii to create the power meters that it launched early in 2018. These use strain gauges built into carbon crank arms and Specialized reckons the system is the lightest and the most precise on the market, with a weight of 440g for the 172.5mm cranks without chainrings.
