Hi,

I am new to cycling. I am trying to make my (prepare to laugh) 1986 Schwinn Sierra MTB into something fast and road-worthy for the winter. For two reasons, I won't be getting a true road bike until late next summer (travelling and money).

Thus far, I put a set of slicks onto the bike, I am waiting for a trekking bar (for more hand positions), I have replaced all the cables, and I replaced the brake pads. Now, I am wondering how to make the bike a touch faster at the top gears. With the current set up I can't get the bike over 30 mph, but I think that I have more in me to do so. I just can't get my cadence high enough. Here is my question: what can I replace to make the bike faster? My cassette has a couple of broken teeth. Should I replace that? Is that easy? How do I know which one will fit my current bike? How about the front chainrings?

Here are the 1986 specs:


Freewheel
Shimano Z 14/32 5 speed

Crank
SR SXC310 28/38/48

Rear Derailleur
Shimano 523 SGS

Front Derailleur
Shimano 204 GS

Shifter
Shimano AT50

Oh, and I should mention that I am willing to trade for a new or recently used Bianchi Vigorelli in good condition

Thanks!
Mike
