Looking to get a P2M meter to start training properly I live in a area with quite a few hills, but also will need it for upcoming races. Unsure whether to get a standard or compact version for my crank as ill need to train up some big hills and also race with the same meter.

    Can't you get a 4 bolt one?

    If you go 110, then at least you can swap out to 52/36 or 38 from 50/34.
    34t is basically next to useless for UK racing

    Yeah id go for the semi compact anyway 52/36, this would be good for hills but whether it'd be sufficient for races also?

    What level of people are you racing against and what terrain?
    I'm sorry you don't believe in miracles

    you can run bigger rings on 110 bcd. when I was fitter, I ran 54/38 without issue (for racing)...

    Just started racing not too long ago and turned cat2 but im only 20. Mixed terrains really some circuits but a lot of climbs also I need to train.

    various, usually TA. they looked crap but were fine.

    At 20 and cat 2, you sound strong enough to me that you should be fine with a 130bcd.

    Especially now that 11-34 cassettes are becoming widely available - I doubt there is much you'd struggle to climb with a 38-34 gear.

    Equally, there's very little reason not to go 110 bcd though - big rings can still be had, and the big manufacturers are standardising on it anyway (albeit in annoying bolt patterns).

    The difference between 52 and 53 in the 11t is 0.7 mph (37.0 vs 37.7).

    If you think you'll need that, then get the 53, but for me, I'd go semi-compact as a 'do anything' gearing. Useful for taking the bike to training camps, etc... too.

    Sound advice, saves swapping anything over in the future! Cheers
