Through axels have become a very convenient excuse for bike changes. Watching Cavendish have his wheels changed in one of the early stages this year was so slow. It took a guy with a drill like a minute plus to do front and rear wheels.

I just learned about through axles last fall. And narrow-wide chain rings (mountain biking). I used to keep up better with the tech changes.

I only caught the end of that wheel change when I realized the mechanic was holding a Milwaukee cordless and Bob(?) was talking about it.
