Different tubs for same rims?
 

Okay, first off I am deff a noob. Im just getting into racing and just graduated college; I'm broke. I have a chance to get a really cheap set of 50mm carbon tubs. I don't know the brand since they're debadged, or never badged? They're just about 1500g, a little under actually. I can get them for like $300 (they're in good shape with low miles, my friend just doesn't want to ride anymore cause he's stupid and became lazy). So the question is, I would want these to be my everyday AND race wheels. Why? you ask, because the wheels I have now are shot and heavy as balls. So, would it be dumb to have an ok training set of tires (with a spare) for commuting/training and just pull them off before a race and put on some nice ones then when done put the trainers back on? Am I just stupid? Again I really want these wheels as well not some cheap pretty light set of wheels ill get those later when I get money to. I don't to pass these up. Thanks for any advice

Changing tires on tubulars, is pretty annoying. Doing it every couple weeks? No thanks.

Buy the tubulars if you want (they sound decent), and put some race tires on them. Then buy some cheap clincher Open Pro/Ultegra or Ultegra/CXP33 or DT 1.1 or something to train on. You can get a nice solid training wheelset that'll last for a long time, for less than $200.

Contact Psimet for a good deal on some handbuilt training wheels, he knows his stuff and has good prices.

I use any tubs as long as the rim has,nt any soap scum.

ha...

You don't want tubulars as everyday wheels.
