Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

American Class 420 Aero opinions?

Anyone have these wheels? They seem to be on par with most of the carbon 38mm+ wheels in weight. They claim to be 1530g per set while Reynolds DV46c is 1480 per set. The difference in weight is only 50 grams a set. But the convenience of aluminum seemed to be very appealing.

i got a set when i got my Felt AR. i wanted aero wheels, in white, aluminum and clincher- as i'd be using them as everyday training wheels.

they are really good wheels. absolutely no complaints.

as a matter of fact, the past three races- i've left my Zed Tech 3s at home and ran the Am Classics.

they are that good. less side to side flex than the Zed Techs, and (ok start your flames) the little bit of added weight i feel, is actually a plus (more rolling momentum). they are also more narrow.

i'm quite happy with them.

I have two sets of them and they're great. I'm 5'5" and 130# so YMMV.

Ditto. 420's aren't the most anything wheel out there, but they're acceptable at pretty much everything and have a good aero/dollar quotient. They don't work well for clydes, so I would call that their main downside.

They're what I race because they are (probably?) the most aero wheel I own and they were $400 on Ebay, so I can replace them pretty easily.

Thanks for the responses, can you guys post some pics of your bikes on these wheels? I am especially curious of the white ones. The 420 white on their site looks very slick...

I too rode them for a time. I sold them now, but they are good wheels. The hubs aren't the fastest things I've ridden, but the build quality is nice and the rims themselves are really strong plus light as well.

I raced on a pair a long time ago. I ended up giving to my Dad, who rode them for years before the rear came out of true. No complaints.

You can get a wheel with a PowerTap from them.

I've been through this with AmClassic. They won't sell you a rim. They are worried about the quality of someone else's build affecting their reputation. However, they will build your PT into a rim. That's what I did and the price was pretty reasonable (I forget how much it was) and they did it fast. Just call 'em up.

I don't have the weight, at 150lbs, but having never rubbed the brakes with plenty of sprints in the 1300 - 1500watt range, I don't think it's a power thing.

These are crit wheels for me, so I don't (knock wood) spend a bunch of time jamming on the brakes. Having said that, they do have a narrow braking surface and they're touchy to getting the pads set up correctly. Not quite enough toe-in and they'll howl like an old dog.

I've gotten a little flex out of them on big climbs when I have taken them on a training ride. Keep in mind, we're talking 20% or better...really steep. I use my Williams 19's for that stuff now. They're stiffer and the braking is significantly better. They're less aero, though, so that's the trade-off.
