I am considering the new 303's coming out soon. I have spoken with the distributor and reputible wheel makers who have all said that the newer versions should see inprovements in wheel build in the area of stiffness. I am currently riding Campy Eurus's and have enjoyed all of the benefits of a bulletproof wheel as they have never let me down . I am looking to go to tubbies and the 303 seems like the perfect comprimise of weight , price, aero and all round capabilities. The question is how light a WW do you need to be in order not to get wheel rub and see good reliable peformance
For some unknown reason, it seems every year Zipp says the same thing about the new model coming out. Best ever, improved this and that, no more this and that, etc. Yet every year tons of people have all kinds of complains about them despite their large sales worldwide. It may simply be that there are so many of them out that the % of problems and failures are no different or even smaller than other brands with much less sales, but because the total number of sales is much larger the number of problems/failures are more noticeable.
Personally, I've never liked Zipp at all. It just seems I hear nothing but problems from locals that have them (Have never owned a set for the same reasons). Granted, none of them are in the 135 Lb range, but we are not talking about porkie 250 Lb guys either with legs like tree trunks. If it is not one thing it is another: bearing issues, cracked rims, cracks at the spoke entrance, extremely frequent spoke truing, rubbing, etc. I just don't hear that from the people running Reynold wheels and others though. It may simply be coincidence.
