Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

They will all of had them but not on all bikes so spare bikes etc might not have them. Pretty sure there was a stage that they said they used compacts so had no power as they never had the SRM's for it

Maybe they never bothered buying them for a single stage worth of spare bikes. If it's extreme enough they need to swap to compacts on spare bikes they're probably not likely worrying about their power, more likely hanging on.
