Thank for the information, that was basically what I figured. The conversion to my LHT is certainly my entire 2010 bike upgrade budget anyway! I was just curious what difference a higher grade DR might present.

I am certainly trying to ride the pants off my Trek right now - when the rain allows - but such is spring.

It will be interesting to see which of my two bikes gets the most mileage once I can really ride my LHT - it doesn't have that aluminum buzz on rough roads!
