You have been very lucky because the 303 rims are quite weak

I dissagree. They side walls may be a little thin on the 2003 models and older, but they have addressed that with the foam injection. I never had any problems with the 2003 models I had though. I am also 195lbs and ride with a lot of power (They are all I race on), so I would have to say they are a pretty strong wheel considering they are carbon.

i am 185 lbs, would you ride on zip 360 (404) tubular rim everyday?

I would guess that the 404's would be a little stiffer than the 303's. As far as training on either 404's or 303's I wouldn't. It pointless. I wouldn't train on any carbon wheels because they are two expensice to replace. Its not a question of durability. Its a question of cost. What happens if you hit a large pot whole. That could tear up any wheel. I usually train on either some hand build wheels or a set of cane creeks. I do ride on the Zipps sometimes if I am going to do a fast group ride though.

oh well, i guess i will just build them up. i hate gluing tires... i would hate to get a flat far away from home.

Use Tufo sealant.

I had a Veloflex Criterium with about 200m on it that suffered from an attack of the thorns. I wouldn't have patched it, there were four holes in it. So as a last resort I tried the sealant (never used it before). Tire is going strong.

Ride lightly!

I have actually found it easier to change a tubular than a clincher. I use an old previously glued tubie as a spare and the change takes as little as 5 min. depending on how well the old tire is glued on. I train and race on tubies now. They just ride much better for me. I would recomend the Tufo sealent also, but I put it in the new tire before mounting. I use all Tufo product infact. There tires are great.

how good is that tufo tape they have? has anyone tried it, or am i going to be the ginnie pig...lol.

Tune Skyline:

i dont want to ride on the 280 rims, i have seen them and i think they are too weak, i may be wrong. thats why i went with the 360 rims, plus they are more aero.

Dude, Zipp 360 rims for everyday use! WAKE UP! These are event wheels dude. Sure you could ride them every day, but man, the brake track after a while will be destroyed, especially with you living in NY City the stop and go that you will be doing. Plus they have a 58mm depth, not the best unless you TT, or on long flats, assuming that the side wind isn't bad. You need to get something else.

MAMA SAID KNOCK YOU OUT! HUH!

hehe, everyone has been telling me the same thing would you like to buy them?

im a little short on cash now, so if i want to finish my bike anytime soon either i build them with these rims or i sell them to buy something else, those are my only options.

It's like paper when you hold them in your hands

When you want strong light wheels: FRM + Ambrosio Crono (Bulltek sports sells them) + CX-Ray 32 spokes: 1295g with Spada hubs: 1280g
Those wheels are strong, light and durable.

hmm, do you have a picture? would you use them everyday? have you used them before?
