Watts

Hi,

Hi,

Has anyone seen this new project? http://www.indiegogo.com/laser-spoke?c=home

The main benefit is that this is totally portable between bikes and wheels - if it works.

I was followed by them on Twitter today and took a look at the video. Seems an interesting idea but they are looking for £85k.

Also they say "affordable" but at a target price of £500 for the UK that still seems too much for a run of the mill cyclist like myself that would like to have power meter data but doesn't really need it that much. I can live with post ride data like Strava / Android for that sort of cost.

I read that Sir C.Hoy puts out 2,300 to 2,500 watts during his 200 metre sprints and I recall some of the TdeF riders averaging over 450 watts for long stages.

There are various ways of measurement - at the pedal, at the crank, at the rear hub and on a turbo trainer - but what's the baseline measurement to do reasonable comparisons between riders?

Presumably there different tests and figures for endurance riders and sprinters, so you couldn't compare Sir Chris with Bradley Wiggins CBE. Does anyone know what they are and how we, mere mortals, compare?
