• SRAM Automatix 2 speed wheel
    Internal centrifugal mechanism (no cables, no shifter).
    I had it built into a wheel using an Ambrosio 700c rim by the renowned wheel builder Big Al of Wheeelcraft (near Glasgow).

    I modified the spring tension that controls the shifting point as per this blog-http://mccraw.co.uk/sram-automatix-review/

    This makes the hub shift up at approx 23 km/hr (according to my GPS watch).
    I'm including a 19 and a 22 tooth sprocket with the wheel. This is a freewheel version- not the coaster brake.

    Set up as a 42 x 19 (as per McCraw's blog), here are the gear inch stats for the hub-
    1st gear 58"
    2nd gear 82"

    Set up as 42 x 22-
    1st 50"
    2nd 68"

    I've only used it for about 500km and it's in almost new condition.

    Looking for £70 (which is a bargain considering the hub alone costs £60).

    No tyre included in sale.

    Location Kilbarchan near Glasgow- I can courier the wheel anywhere within the UK.
