I was looking around for information about the 2013 Karakoram 2.0 stock rims, and I couldn't find very much. I eventually decided I to pick up a new wheel set, my third upgrade after a Manitou Tower Pro and pair of VP Components VP-001 pedals.

My Sun Ringle Black Flag Pros arrived today, and I thought I'd weigh both the stock and new wheels as I moved the rotors to the new bike. (I'm waiting for some Maxxis Ardent tires to come in that I'm going to run tubeless on the Black Flags.) I put some inexpensive rotors on the TD19s, and I'm going to keep them otherwise as is and run them at 65 PSI as my weekday commute tires. In the not to distant future, I'll probably pick up a pair of 700x32 road slicks for the TD19s, and keep the Aspens as back up tires.

Here are the results of the configurations I did weigh:

Front F w/ Rotor Rear R w/ Rot R w/ Rot + Cas.
AlexRims TD19 1029 1178 didn't weigh 1423 1850
Black Flag Pro 839 988 948 1097 1522
Difference 190 grams 190 grams 326 grams 328 grams

The measurements were pretty consistent. Keep in mind that I kept the spoke protector and reflectors on the TD19s, as they're going to be my commuting tires, and that the cassette on the TD19 is not the exact same cassette as the one on the Black Flag Pro, not that the 2 grams is a big difference. Also, if it helps, the Black Flag Pro's list their weight as 1725g in their lightest possible configuration. I get 1787g as their combined weight when set up for use with quick release skewers in front and back.

I didn't buy the new wheels to be a weight weenie, but I did want wider rims and to go tubeless at lower pressures with tires that would give me better traction off road, so my goal wasn't to see how much lighter the wheels are, but to provide information for people that might be helpful, since I couldn't find much when I went looking.
