Thanks! So it's closer to the 300gm. mark. I figured it was in there somewhere.
> Actually, Columbus does publish the weight of all of those older tube sets. Weight given in grams in the specs. My guess, all else being equal, the weight difference between a frame made identical to another, other than these tube sets, is between 100 and 300 grams. Probably closer to the 100 gram figure. It's not as much as one might imagine.
KL: 1670 grams SL: 1925 grams
for a 53 cm frame -- mvg
