Look’s Power Meter from 1990
Simon Masters has been reminiscing on G+ with old Winning covers and ads, like this one for a Look power meter.
In the 90s, Winning magazine was a source for bike racing news
I remember seeing Winning in a bike shop and being given a copy to read up on “training” and echelons. Don’t remember Look’s power system and they’ve got a new one now. Few remember Mavic’s electronic shifting either.
