I'm still on 11s, mechnical, clincher/tubular and rim brake on my two road bikes and TT bike. I feel my returns would be quite diminishing for my investment in any newer technology, at least for the relatively light and easy cycling conditions that we have in San Diego. I do enjoy tubeless and discs on my MTB, where I think we can all agree it makes a much bigger difference.
