• I’m looking at getting a power meter. I have just the one bike, which is a disc road bike.
    I’m leaning towards a power-tap either hub or pedals dual sided.
    I’ve come to this decision as I’m right sided dominant and the left only, sounds like it might not be very good, especially for right side dominant people.
    However dual sided is obviously much more spendy. Any other considerations?

  • I wouldn't say it has to be much more spendy. Have a look at the P2M NGeco, if you buy spider only it's comparable with some Left only units. Also look at Quarq, the Dzero crank is sub £500 on CRC.

    If you do decide on hub, expect a new disc version G4 to be out soon (ok maybe early 2019). I think the current G3 requires proprietary rotors.

  • I did wonder if a new power tap hub was due. As they seem to be a little thin on the ground. You are correct about the disc too.
    Ok I’ll have a look at those.
    Are the accuracies (or in) as bad as they seemingly are made out?
    Also does it really matter? Presumably consistency of reading is more important for training.

  • the current G3 requires proprietary rotors

    It does. £80 a piece.
