  • Yeah, it ain't that steep, but it's damn relentless. Which exit did you guys use?

    How did ya find spinning downhill? I've got 69" and in the tunnel you can easy get 30mph going downhill probably more if you draft a slowish car or bus. I need to practice spinning at 150+rpm. I've seen people do close to 200rpm on audaxes before, but it looks fucking scary, especially on peak district descents.

    See for the sheldon endorsed calculator

    I was running 70" and it was fine, very spinny but not too bad due to the lack of traffic. We went straight through to the library exit, tough to keep up speed towards the end.
