    Mountain Bike to Road tweaking

    Pardon me while my Freddiness sticks out for a moment.

    I have virtually no budget to get a road bike which means I may be in for another season of road biking with my old Univega mountain bike. In order to improve my speed on flats and descents (and have more fun), is there any reason I can't purchase a used crankset on Ebay that would get me up to a 50 or 53? Or is this just dumb?

    Oh, and Merry Christmas!

    See if you can find bigger chainrings for your current crank.
    That would save the remove/replace of the crankset and save money too.

    Assuming you have something like 44/32/22 it's probably easiest to swap out for 48/36/26. Most mtb fds will accommodate this. You need to ensure that the size difference between the rings is not excessive unless you are going to run single ring. Also check out the BCD most road bike outer/middle rings are 130mm mtbs are 110mm.

    If you're not yet doing so, switching to 1" slick tires would be a cheaper and just as effective option.
