tubes v. no tubes

so i just read an article by Tony Ellsowrth (Ellsworth bikes- i always dreamed of owning one) about tubes and tubeless systems and it echoed my opinions. i ran tubeless for 2 years 2007 thru 2008 (until i got my gt i guess) and i liked how i didint get pinch flats- however, i never got pinch flats to begin with. but mr. Ellsworth explains that tubeless tires are super heavy, and i noticed that with my tubeless nevegals. also, in a race (or even a long ride), you need to hope that the stans/slime (hate both)in your wheel stops the air leak. i ran a tubeless maxxxxxxis crossmark when i first got my zaskar and my tire would go flat ever 2 days. it normally wouldn't be a problem, but it made me mad on a carbon race bike. after a while of messin around i noticed that there was a tiny pinhole in my tire and it just didnt really hold air overnight, and i didnt want to risk it on a 2+ hour ride. that being said, i came to the conclusion around july of this summer that tubes are the way to go. tires are lighter, which is a plus because they are the farthest part from the hub that is rotating (multiply grams x 4 to get true rotational weight). also, tubes arent that heavy, and they are easy to replace (i am the flat tire czar etc). they make ultralight tubes- i had them on all my mtbs, but the ones in my gt gave way during the last 3 weeks- and they are really light. i ride them in my IF ss and when i first installed them in the wheels i was blown away by how light they were (again, remember rotational weight). i do, however, run DH tubes in my tires now on my gt because they were free and i know they wont pop on rocky race courses. i go back to a previous point, if your running a sealant during a race you better hope it works, if not you need a new $60 tire (who carries them during a race?). a tube takes 2 minutes to change at most (thats with the presta cap and valve retention ring jawn)- and the co2 pumps work great (i just had a 8 dollar flat tire fixup cause i dont carry a handpump now- thans beto). all in all, i liked my tubeless nevegals when they worked, but they were a beefy non race tire- they still went flat every few days too. but, for racing i think tubes and tires are the way to go until someone creates a better system.

oh, i raced the other day and it was awesome, but im too lazy/bizzy to write about it. school work sucks... and riding bikes in the last of the pittsburgh mediocre weather is important.
