Thomas, did you find the the Enve out performed the other tires at 0 and 10 degrees with the 23 mm tire? And if so, what 23 mm tire did you test? Do you have a link for the results?

Any info yet as to how the Enve wheel compares to the new Zipp 858?

Thomas,

I'm trying to decide on whether to keep my HED Jet 9+ front wheel with Conti Attack or go with an Enve 7.8 front wheel with a 23 Corsa Speed. Any thoughts? My bike is a 2nd gen Speed Concept. Thanks.

No, I'm not having issues. Just trying to squeeze as much speed as possible out of my rig. I know that the Corsa Speed is the fastest tire and I presume mates better with the wider brake track on the Enve. As you know, the HED has a wider ID, but narrower brake track. My Conti Attack is almost identical mounted (25mm) to the brake track width on the HED. You think the 6 is faster too? Thanks.

Perhaps it is the tire choice that makes the difference in drag. You found the 23 mm tire in the Enve was faster at 0 to 10 degrees but earlier in this thread Enve's graph shows the 25 mm to be better. Also its interesting that Enve shows on their website the 7.8 in the tunnel in a Cervelo P5 but my understanding is that a 25 front tire won't fit a P5. I have to find out what Jim's magical fix was. It looks like Amber Neben was riding an Enve 7.8 in her P5-3. Wonder what tire width she was on?

I am not saying Enve is lying, I like their wheels, I really do and had a set of 7.8s, but it is part of the reason I wanted to test different width tires to see if the marketing met the math. And as a reminder according to Enve you should not use latex tubes and there goes any savings.

The specific numbers aren't mine to give out, but I can confirm this is absolutely the case. Repeated the results multiple times. The ENVE is sensitive to tire width, but once a 25 was installed, nothing else got all that close to it. HED, Zipp, and Knight's were part of the testing.

I have no data on the new 808's, so not a comparison to those!

For this ONE particular test. Just one rider with one bike (very important to note this), I would rank the results as:

1. ENVE 7.8
2. HED (least sensitive to tire width)



The other guys.

I think I'm okay to say the wheels were tested on a Cervelo P5-3. Now then, the 25mm Conti will not initially fit the Cervelo with the ENVE wheel (tire is too tall and rubs). A little magic was performed to get it to fit...just a little.

Has anyone owned / ridden both (ie switched from one to the other)? What were your impressions? Which did you like better and why? I’m particularly interested in handling, road feel, and braking performance.

Not on hypothetical or on-paper differences, but real world tests, starting at 8:15 in the video: https://www.youtube.com/...10&v=h0BH3wXzhrI

Thanks. This is a great video.

I do wonder if tester was somewhat biased torwards the ENVEs (perhaps he personally owns them?) as he has a big silly grin on his face talking about the ENVEs and looks almost pained to speak positively about the ZIPPs.

In the test he was comparing handling of 7.8s to 808s. How would handling compare to a 404/808 combo, or even a 303/808?

I know the ENVE 7 front is a very fast wheel, but I’m worried about it on gusty days. Do people run the 8 rear with an ENVE 5 front?
