    the right bike question

    Hi!

    I have a rather stupid question.
    But I just started racing and wondered how much time do you think I could save by changing my 120 mm Stumpjumper to some 100 mm race fully (like Cannondale Scalpel, Cube AMS, Giant Aanthem X, Scott Spark, Spec Epic, Trek TopFuel or something similar)?

    Let's say for a race of 2 to 2,5 hours (some 25 miles), would I save less than a minute, five minutes or more?

    Cheers!

    I don't think there is some set equation to how much time you would save. It would probably depend more on bike fit and how comfortable you are on the bike.

    After all, it isn't like your current ride is a wally world special or something.

    Weight savings will make climbing easier. For example if your combined body and bike weight were 200 lbs and you lopped 4 lbs off the bike, you'd be performing 2% less work against gravity. So if the race were just a climb, and wind and rolling resistance were negligible, you'd be 2% faster. The reduced weight would also make it easier to accelerate out of turns, same reasoning.

    If you reduce YOUR weight you can save even more time.

    Depends on the rider, of course.

    But yeah, most of us could stand to lose a few. It's just that ongoing battle.

    He's ripped!


    but he does go uphill really fast. Too bad he crashes everywhere else.

    I think it would depend on how much climbing there is on the course.

    If you have fun on your current bike keep it and be happy. If you really enjoy going fast and want to find out how fast you can go, get something new, train your arse off and find out.

    Cheers!

    Well, he managed to stay upright long enough to win XC Worlds in 1999.

    If its keeping you off of the podium it is time to change rides, otherwise no worries .
