I have two bikes that I use for commuting.

The first bike is a Poprad cyclocross bike, and the second bike is a Trek 800 sport mountain bike.

To set the Poprad up for my commute, I had to replace the entire drive train for a total cost of $500.

To replace the crank, chain, and cassette on the Trek cost $35. Granted, I bought nashbar 7-speed MTB components.

Is it just me or are MTB components on average cheaper than road components? Deals on road components are not as easy to find.
