^^^ crap.


Was that me?

not in my opinion

Pardon, 5 minutes and change. Clicked through fine for me, but if not search for "Advanced Composite Technology Manufacturing.mp4" posted by "ekkisport." Be assured, I have no affiliation, other than as an interested viewer.

BTW. I'm going with Mango too. Has visual snap without being ostentatious. Perhaps with black spokes and nipples.

Post pictures and a ride report, or it didn't happen.

Robert,

The margins I quote are based on my day to day working experience. They are spot on.

The move to Asian manufacturing happened years ago and is the only reason prices are as low as they are now.

BHS is blowing out rims because they can't sell them. This is a discounter situation and does not reflect market prices. I KNOW what they paid for those rims as I used to sell them in the OE.

Honestly, unless you stick you face in a business there is no way to understand all the fixed or hidden costs and what the final PROFIT is. This is true for any industry.

As to what Performance CLEARS OUT DEAD STOCK at trust me it is not "way above" dealer cost. They are simply trying to recoup their capitol.

We should start a new thread about this.

I am happy with where we are for now, and am sensitive to the displeasure expressed by many folks reading this thread solely to follow bianchi10s adventures in wheel acquisition (as it should be). :) Seriously, I really mean it! If you would like to continue this in another thread, I would be happy to participate as appropriate, but as for here, I guess I am done. Thanks to you and so many others for your patient replies.

Oh, ok..

Then, BURN THE WITCH! BURN THE WITCH!

gc3 03-19-13 09:08 AM

that's right, let's get back to criticizing Bianchi's wheel choice!

JoelS 03-19-13 09:35 AM

No criticism required, that is unless he doesn't choose black hubs :rolleyes:

bianchi10 03-19-13 09:41 AM

Lol, I'm still on the fence.

+1 for mango!:thumb:

From another guy with a black and white frame with black hubs, spokes, and rims who would now prefer a little color splash. 'Cept my new build hubs will be red...

The MANGO train is gaining momentum.

We've sold a lot of Mango CK hubs. They're balls hot.

Personally, pewter is my favorite, but I could see how you could see a purple hue to it. Blue is also outstanding.

Is this the part where we start the chant?

Campag4life 03-19-13 10:08 AM

5 stars for C2...
 
OP...thought you would like some reinforcement for your decision. Rare to have such a sterling review of any product:
http://www.bikeradar.com/gear/catego...elset-08-32321

Granted..that is with HED hubs...and believe you do well with another decision there....which you have made. Sounds as though bearing life...reading comments maybe a bit suspect.

Btw...mango is the new pewter. ;)

Bob Dopolina 03-19-13 10:37 AM

Bianchi,

If you go mango PM me and I will send you the blue tape you'll need to finish that baby off.

svtmike 03-19-13 10:41 AM

Given a choice of black, gold, or mango I have to say Mango as well, gold a distant second and black an even more distant third.

And I agree on the CK pewter.

Edonis13 03-19-13 10:47 AM

mango....... mango........ mango........ mango!!!!!!

dang it, now im hungry. :(

bobonker 03-19-13 01:46 PM

I like the Mango, too. :thumb:

I have enjoyed reading most all of these 21 pages of wheel testing and Bianchi, you are fortunate to get to test a variety of different sets. The owner of the wheel shop made you a lucky man to get to try out such different wheels. Clearly, you love the Enve carbon wheels and they are clearly your favorite. I understand the concerns about spending that much money but clearly from your comments, you love them. When it comes to tools, we had an old saying, "buy the best and cry once."

knowledgdropper 03-19-13 03:03 PM

Great thread, even with the numerous side-trips. As for hub color....

I'll say it again: you will not actually FEEL the difference between two different wheel sets on chip seal. Not if they're both properly tensioned. You will, however, HEAR a difference as you go over the bumps, and the more percussive, hollow sounds from a deep section aero rim compared to the muffled sounds of a 32 spoke 3x box section will determine your perception to a large degree.

Because this thread has slowed down a bit, I thought I would respond to Banzai's post. Does anybody here believe this? I don't.
Wheel differences aren't just auditory. Stiffness difference between different wheelsets does of course change the resonant frequency which affects sound as they resonate at a different frequency but stiffness differences between different types of wheels manifest more in terms of feel. Just like a soft versus stiff frame difference doesn't just sound different...vibration of frame and wheels can be felt kinesthetically.

What I wonder is what is meant by "determine your perception". Is that supposed to suggest that the sound will make one seem better? Which one? Might it differ from rider to rider how the sound is interpreted? I do know that chip seal is so damn aggravating that I could imagine the difference in feel to be negligible, you know awful and very nearly awful. But how is the sound to be understood?

svtmike 03-19-13 03:36 PM

I don't believe it either, although I do believe that differences in the stiffness of wheels are far more apparent when you're throwing the bike around a tight corner or sprinting as opposed to just rolling over chipseal (and I'm not even sure why that particular qualification is in there).

That said, I can't say that I've ever gone and done any specific A/B testing of this question leaving everything the same (bike, tires, location, timeframe) except the wheels.

Campag4life 03-19-13 04:11 PM

I believe his point is the feel difference is overblown and we 'feel' partly with our ears. I know this true of riding with guys with deep section carbon wheels. They have a very different sound aka they resonate differently than more conventional section aluminum wheels. I believe the sound versus feel equation is in terms of rider perception to be just that...a complex of sound and feel.

Three elements make up the stiffness of the wheel:
1. Rim stiffness...carbon and deeper section rims tend to have higher radial stiffness. (section modulus/moment of Inertia...yada)
2. Spoke count. Greater number of spokes = more unified connection between hub and rim. (spoke tension is a non contributor in the elastic zone)
3. Spoke cross-section. Thinner gauge butted spokes tend to elongate more for the same level of wheel force aka they are more flexible.

In aggragate, 1-3 above either contribute to a stiff or a less stiff wheel, latter some may even classify as whippy or flexible amplifed in particular for a heavy rider with greater wheel forces.

To me, over and above tire pressure and volume, wheel stiffness matters for ride quality. How a wheel sounds is only part of the equation.

svtmike 03-19-13 04:19 PM

Agreed. There is a definite difference in how wheels sound along with how they feel. For the case of rolling on chipseal, the radially stiffer wheel will have a harsher ride quality. How much of that harshness gets to the rider depends on the damping quality of the frame.
