Black Friday deals bring down power meter prices

4iiii Precision hits a new pricing low

For years, power meters were a serious investment that was hard to justify unless you were, like, good at riding bikes. Now, that's all changed.

This year's round of Black Friday deals has produced a bit of a stunner in the form of this 4iiii Precision 105, which Ribble Cycles is currently selling for just £314.29 / €353.36. (This is an EU-only deal, but the 4iiii is only $399.99 at retail in the US anyway.)

That's not as cheap as the recently announced second generation Watteam Powerbeat which retails at $259 in the US (for a power meter only, which you can fit to your crank yourself), but it's a pretty exceptional deal this side of the pond. 

The 4iiii deal is for a left-hand crank only of course, but it will fit all Hollowtech II cranksets, so you can add power to basically any Shimano-equipped bike as long as the clearance for the power meter pod is there. (And as long as you aren't precious about mixing 105 with higher or lower-tier groupsets!)

The Precision adds about 10g over a standard crank arm, which is about what a mouthful of energy drink weighs. 

It uses ANT+ and/or Bluetooth to communicate data and claims to manage 100 hours plus of riding time from a tiny coin cell battery.

Our very own Ben Delaney tested the Dura-Ace version of the Precision last year and awarded it 3.5/5 stars. It wasn't perfect, but he found it to be a generally reliable and useful training tool.

4iiii isn't the only brand of power meter you can find bargains on right now. This Stages Ultegra 6800 is currently discounted from $579.99 to $399.99 at Performance Bike, and we're expecting more deals in the lead-up to Black Friday and Cyber Monday.
