Sometimes a new jersey cures the compulsion to shop - and a lot cheaper too! Sometimes I just wash my bike - voila! New bike!

Seriously, you don't say what components you have now, so I'm assuming you're riding the lower rung of Brand X. I love my Campy Chorus & have over 50K miles on my bike with the same components. New rims might be nice too. Just watch that you don't invest a bunch of $$ and then switch bikes. You could always keep this as your around town bike - especially for those Wisc. winters.

Bottom line - if you are fairly new to the sport you might want to train more to get faster. A new bike might shave a bit of time, but saddle time is what you need.
