    When racing is understandable, hard to prioritise drivetrain lifespan at 180bpm!

    At 180bpm a plastic drivetrain would last a lot longer than me!

    Can you get them in a compact?

    No racing experience myself but I've got a 52-39 and a 13-26 cassette. I'm rarely looking for a 11t or even 12t. Can spin up to around 60kph (120rpm in 52x13) if the wind and gradient allows it. Although I'm a bit of a lightweight so I tend to have lower terminal speeds on descents regardless of power.

    I'd imagine if you can spin out a 12t cog on a descent you'd either be better off tucking, or you really need to work on your leg speed. Sprints might be different as you can't maintain as high a cadence while standing and mashing I guess.

    [about the big chainring x big cog combination.........] I try and avoid it when racing (and always avoid it when not) but sometimes don't realise I'm on the largest cog, or will do it for a short time if I'm about to crest a hill

    does the noise not remind you no :confused:
