Since I've had my replacement my Stages has been faultless and is easily swapped between 4 bikes that have GXP cranksets so for a relatively modest sum I have what appears to be repeatable power across a wide range of my bikes. OK, Xav thinks it Mickey Mouse data and I'm sure compared to SRM it is, but to be perfectly honest it's more than good enough for me as an enthusiastic amateur to base some basic training on/make the turbo more specific and bearable/measure approx gains in performance. And I can use it on my fixed gear bike which has a Omnium, so GXP system. I'm well pleased with mine for £599 despite the naysayers.
