WOW. first ride on aero wheels:

so, I bought a set of 56mm deep Easton carbon tubulars (tempest II) with conti gp4000 (with black chili) tires on discount in december. Until today they've sat in my basement waiting for OK weather and race season. I rode them today for the first time, just to get them dialed in for tomorrow's race.

All I can say is: holy crap. I knew they'd be fast, but damn.

They feel pretty normal at lower speeds, but get them up around 25 and they just seems to want to go faster. I hit 37 on a downhill that normally gets me to 34... and I wasn't trying to go particularly fast.

I had a few buddies lead me out for a form sprint and the extra bit of speed once i really poured it on is actually a bit scary. the lightness of the wheels makes them feel a bit less grounded, too... sounds weird, but pulling on the bars hard lifts the front wheel with less effort.

Where i felt them most dramatically was on 3-4% up-gradients while really pushing the pace. The combo of aero and light weight really becomes apparent here as they seem to hold speed easier and make my pedal stroke smoother.

I'm glad that they are this much better, as they cost an f'in fortune, but I'm shocked at how noticeable the difference is. I was riding race X lites with pro2race tires prior to these on the race rig, so no slobs in the wheel world.

At 190 and a sprinter type, they feel solid and strong. They also feel comfortable/supple which is saying a lot on a caad7 with aluminum post and hard saddle.

Of course I have no real hard evidence to support any of this, but I'm really floored.

Oh yah, and they look soooooooooo good.

So, I'm spoiled now.

anyone else have this kind of reaction when riding aero tubulars for the first time? anyone else feel a little bad about buying speed??

thanks for reading this babble,

-L

A team mate of mine summed it up when I asked him about his zipps: "When I'm riding them in a race I feel brilliant. When I look at them hanging in the garage I feel like a dumb ass."

Mine seriously live in wheel bags so I don't have to think about them every time I walk by.

Now imagine how 1300 gram Fifty EIGHT cm Zipp 404 Carbon wheels with Conti Sprinters pumped to 170 psi feel. And that's why I am convinced that it's by far the most effective dough I ever spent on bike schwag. I race on them every weekend and appreciate them every lap. They really are wonderful wheels, and by far the most meaningful upgrade you can make to a racing bike.

If you're skeptical, at your next race, ask ANYONE with Zipp or similar aero carbon wheels if they like their wheels. Get back to us if you can find somebody who doesn't tell you what I'm telling you, because I haven't met anyone like that yet.

Pcad, i agree with you except for the 170 psi part. 170 psi is for wooden velodromes.

I run mine @ 160lbs, I have team mates that run them @ 170lbs. At 160lbs the Conti Sprinters I ride are amazingly resiliant and comfortable. I mostly race them on smooth closed courses, but I train on the open road with them once a week, and I like them even on moderately choppy pavement. I haven't ridden regularly on tubulars in a decade or so, and now I remember what I liked about them. They are a nice change from clinchers. I put most of my miles on Conti GP4000 clinchers, but it's nice riding those tubies on the fast rides and races.

I had the understanding that tubies were ran at high pressures like that...

All I own is clinchers.(obviously)

My personal experience with tubulars and various testings floating around the web show that most tires have the least amount of rolling resistance at between 100-120 psi. When the PSI is too high, the casing can't deform locally over bumps, which is what gives tubs their magic ride in the first place.

Just saying.

I didn't read the other posts, but.

When I slap on my 404's, I feel like my bike is on crack. It's like 99% placebo, but I just go fast. Real fast.

I feel slower on my Zipp 404s (clinchers, dimples, PT rear hub). I'm not sure why, but I do. I might sell them because I never use them anymore.

Riding tubs at 170 psi is ******** unless you're on a track. It's not faster, really. In fact it's way slower. Check out all the RR tests in magazines like Tour (german).

Eh, just wait until the placebo effect wears of... or you start noticing the people on Open Pros still beating you to the finish

Regarding these wheels, I'd love to have a similar set. Still, I think I go faster when my competition has them. I sprinted against three sets of 50mm carbon rims, mounted on carbon frames (Orca, Addict, Look), from our break on Sunday. Those wheels didn't seem to add enough speed to keep up with my 32h front Deep-V and 32h rear AeroheadOC.

I haven't seen anything to that effect for tubulars; , not that I disagree. If you have a study, I'd love to read it.

a 0.1 second advantage may be all it takes to win or lose the sprint, though.
