I am right, aren't I?

Well, I've got somebody saying, that a lighter drivetrain means easier motion. Where did that come from? Easier motion/acceleration firstly comes light wheels, tyres, tubes and the rest of the wheel assembly, eg rotors and cassette as it cuts down on rotational weight. Shouldn't you be making changes to the forks to cut weight and improve performance way before the drivetrain? The drivetrain can be upgraded when it wears.

For anybody who can be bothered to get the full story, here it is:

    Just to note, cassette is part of the drivetrain....

    But anyway, it would help, but other places would help more

    It is best to save rotaing weight, but the diamater of the cassette and chainrings are som small it makes next to no difference. And it only affects acceleration anyway.

    Tyres, wheels, forks always.

    I'm not that stupid :lol: I'm saying, updrage wheels and tyres first and then do the drivetrain when it wears.

    Good to know, I got it basically right as I said wheels and forks first.

    It's alright now. He's been taught that he's wrong by the forum gods, both on mtbe and on here now. He seemed to think that lightening the chainset would make more differnce than lightening tyres and wheels.

    tyres and rims make the biggest diffrence to acceleration esp the rear. a coulpe of lb of static weight is pretty un-noticable unless your running for hours on the limit ie xc racing.

    1lb+ from a fork does have a noticable effect on how planted the front is on climbs too

    Meh, it's a bike, just get on it and ride it. You probably get fitter by actually riding than fussing over weight and performance.
