Zipp Or Amclassic.(6 posts)

Zipp Or Amclassic.S-U-B
Jan 30, 2003 10:09 AM
Thinking of getting a new set of wheels and can't decide which way to go. Zipp 303/404 or amclassic 420's. Wheels will be used for road racing, possibly crits as well. wouldn't mind putting in some miles on them on a daily basis if durability isn't a question. I currently have 2 sets of K's (would sell one) and a pair of Mavic Cosmos. Any opinions, experience with these wheels appriciated. I do alot of climbing because I live in the mountains if this helps.

The difference in price is huge. The AC hubs have given some people problems but with the savings you could rebuild with new hubs and have money to spare.

BTW: I have a pair of '01 Zipp 303s. They have been great. I got them before AC offered the 420s. If I were making the purchase now, I would go for the 420s.

Why would you go for the 420's now? I have heard some people having problems with the Zipps on long descents and the aluminum braking surface warping. Is this a real problem or do these people just need to learn how to ride? I'm crazy on the descents and I dont want my wheels holding me back. Thanks for the reply

I should have clarified. I have the 303 tubulars. I've heard minimal chatter about aluminum/carbon separation. Never heard anything about warping issues.

The aluminum rim on the Zipps is not impressive, IMO. You can clearly see the seam and the braking surface is not well machined. In my mind, Zipp makes its money on the carbon rim. The aluminum was an afterthought, added just to appease those who demanded a clincher rim.

Price would be my biggest factor for choosing the ACs. They are cheap compared to the Zipps. In the last two years Zipps has jacked up their prices without offering a significant improvement. I got my 303s for $900 in '01. Now they are going for $1350 although they've only seem minimal refinements.

I know for a fact that the price of their materials has gone through the roof. The hubs are much improved, and they are using Sapim spokes. The same spokes all the pros use on their wheels. Plus, they are putting a visco-elastic dampening material that is reducing vibration to the rider by like 30%. And for the clincher stuff, they have come a long way in fixing the aluminum/carbon bonding problem. It is an extensive process. How do I know? Because I've actually prepped the rims. As for me, I don't know anything about the 420's. But I can say that I race a pair of 404's. I wouldn't trade them for anything.

They offer a bunch of options, such as spoke selection and number.

Moreover, AM has apparently fixed their bearings problem and according to a review (its on their site, so of course its positive..) they run very smoothly.

If you are thinking of spending the $$ on the zipps, have a look at AM's carbon dream set, they are nice too!
