Welcome to WireWorld. It serves no other major purpose to waste the Wirehead's time, entertain, and let you know a little bit about the Wirehead.
Agreed. I'd add that disk brake pads wear out in 700 - 900 miles. That's a month for a commuter like me. I rode my Schwinn Mesa's caliper brakes for 20 years without a thought.
Interesting. I've got a Dawes hybrid and I don't like the flat bar. I used to have a bike with drops and would like to go back to them, but it's hard trying to figure out brake and gear levers without re-engineering or spending a lot. You've obviously put a bit of thought into it all. Food for thought.
