Okay, seamuis, I guess I have been sort of a right bully here lately. I apologize for that.* SS/FG forum seems to bring that out in me. I don't know what a tosser is because it's not a common term in American English, but I'm probably guilty as charged on that one too. I swear I'm a pretty nice guy in person and we'd get along fine if we met on the street.
Your approach to cycling is curious. You advocate for light weight wheels, something we can all agree contributes to efficiency. You also insist it makes a difference to ride with the most efficient drivetrain possible; fine--I'll concede on that for the sake of discussion. In another thread you say you don't like skinny tires because they're uncomfortable--harsh ride or something, was the gist of it. Not trying to put words in your mouth, but I'm sure you wrote that your bones get shaken loose by anything narrower than 28mm. So you're taking two steps forward and one step back. Your preferred setup is analogous to eating eggs Benedict, with cheesecake for dessert, but drinking Diet Coke with it to save calories. In terms of efficiency, how do huge chain rings and cogs vs. smaller ones of the same ratio make up to any significant extent for the weight difference between 25mm and 32+mm tires? I'm not calling names and not trying to insult you. Just looking to understand the philosophy that drives your bike component choices.
* My apologies to the OP as well. I'm just some dude cruising around Utah on a second-hand Surly Steamroller. It's doubtful any of us will get invited to the Tour de France. That's all I was trying to say before.
