Wow, thank you for checking the weight.
-The DT FAQs state that the suspension fork adds 1.5 pounds to the weight of the bike.
-The DT 4sale section states: " All aluminum lowers with a 1 1/8" threaded steel steerer for 20" wheel bikes 1.5 lbs".
Somewhere, maybe, we are missing another 1.5 pounds of DT suspension fork weight to trim.
