  • Inaugural ride (from Peckham to Camberwell, what an adventure!) on the Orbit.
    I think the frame tracking was successful... All felt normal, the usual tandem long wheelbase "offset" feeling, but it feels much easier and faster than the Sun, which was the whole point of the upgrade, we should be able to go further away than London intra now is...
    The upright position kills is likely to hurt my butt on longer rides, I may try a Brooks pro instead, the wider rear may help, but ultimately I may revert to drops and spread more my (heavy) self load more on to my arms, if I can't improve this.

    Then... Then I realised that unlike what I was convinced of, the timing chainrings were not the same teeth count! Duh! Last night I re-adjusted twice without realising.
    Luckily I had a spare ring and all is now normal. So weird to cycle out of tune!
    So far, success!

  • the timing chainrings were not the same teeth count!

    That would be fun :-)

    If your tooth count is not an integer multiple of the chainring bolt count, make sure you have both rings clocked the same so that you eliminate chordal action.
