I have a Giant Yukon, Use it for commuting, Ave speed is 20 mph, when I push it I can do 27mph or just a little over, the thing is at that speed my legs are spinning like a chipmonk on acid, Im pretty new to all this so is there a way I can change the gears for more speed ? If there is a way what sort of cost ?

Thanks Guys

    Larger front chainring (provided the ones you already have are bolt on, not riveted on)

    Cost from £20

    No. teeth. Your current outer ring is most likely 42 tooth.

    You can get 44, 46, 48... even more. Whether they work with your front derailer is another matter. Look into it.

    When I were a wee lad I could get more than that out of a 44/11 at big revs.

    Have a look through here

    I think you will need to make sure that whatever you buy is 4-bolt, and designed for 8/9 speed. Also I may be wrong and people can shoot me down or back me up but will need to be an outer ring so not designed for single speed.

    ie http://www.chainreactioncycles.com/Models.aspx?ModelID=706

    I know that one is a little pricey but makes a good example of the 4 / 5 bolt.
