Congrats on your new LHT! I am just breaking in a LHT that I bought (used) on eBay a couple of weeks ago. I had two pinch flats in the first 30 miles on the stock LHT Slickasaurus tires. I upgraded to some 2" Schwalbe Marathon Supremes (my LHT is a 54cm w/ 26" wheels) last week. The Supremes provide excellent traction, awesome comfort and a high level of flat resistance, at the cost of a sleight gain in weight and rolling resistance: definitely a "win" for me at 235 lbs. I am using my LHT for commuting several times a week (just over 20 miles round trip) and weekend recreational riding, typically averaging 60-80 miles per week.
Your bike looks sharp! What kind of fenders did you put on your LHT?
