It doesn't work the same way though. If you're starting out and wanting to get stronger, it's actually better to ride a heavier bike. It'll make you train harder. Then when you get on a race bike (or swap parts out to lighter/race ones), you're all the faster.

There are also disadvantages for using race components to train on - they're easier to break (and expensive to replace when they do).
