New Wheels

[PsyDoc]

Here are three pics of my new wheels...finally after a week... and how the rear hub sounds. The saddle is level, though it does not look it in the pic. For comparison purposes, I also included a DA7700, a Ultegra 6500, and a Chris King rear hub recording.

The specs of the build are DT Swiss all the way around. 28 hole front with Revolutions laced 2x = 650grams. 32 hole rear laced 3x with Competitions drive side and 2x Revolutions non-drive side = 830 grams. If you are on the road when cruising about 18 or so and stop pedaling, then you can hardly hear the DT 240s. Right now, the rear hub is much much quieter than my DA7700 hub, but not as quiet as my wife's 28 hole DA7700 hub that is virtually silent. The reason the wheels did not go on the bike right away was an issue with the rear hub build that was resolved with Excel Sports.

Nice looking bike. You will enjoy the DT wheels. Spokes talked me into a set (as well as some of the other riders around here). I think he sold quite a few pair over the past 6 months.

I am still partial to the king and the dura ace sound-

I guess cuz thats what I ride ;)

Nice wheels! I've got nearly the same set-up, and had some concerns about the sounds coming from the rear hub myself:

I never really thought about recording it, though!

nice bro they are what e-richie recomends that's good enough for me they must be nice I'm goin to get a pair as soon as I can find a deal on them on ebay cheers :beer:

I have thought about posting a page on my website that has sounds for as many different hubs as I can get recordings. You see postings where the person asks "how noisy is the rear hub?" Might be a good resource for those with such concerns.

Send SPOKES a note and he can probably get you set up with a pair.

i have a Chris King t-shirt with a saying from a Japanese client who wanted to compliment the hubs, his turn of phrase was:

"rolls good, with angry bee sound"

Perfect description of the product! Just rolling on my singlespeed hubs makes me smile :)

It is weird they laced your trailing spokes on the outside.

Can anyone explain to me why the poster sees this as weird? I know there are different philosophies about building and lacing wheels, but I have not taken the time to try and understand them. Can anyone give me a reader's digest version?

The King hubs sound like a fishin reel to me. ;)

The trailing spokes (or pulling spokes) in the photo are the ones that have their elbow on the outside of the hub flange. Their heads (mushroom shape) is on the inside of the flange.

Sheldon Brown and other wheel builders believe since these spokes see higher tensions than the leading spokes they should be laced from the hub to the rim via the most direct path and "elbows in".

A whole bunch of other builders, including Dave Thomas, believe "elbows out" makes for a stronger build.

In my experience, my one build with "elbows out" flex's more and the drive side spokes sometimes touch the rear derailier when grinding up a hill in 1st gear. I therefore build wheels "elbows in".

hope this helps,

I also found some info from velonews where DT Swiss weighed in on the question:

DT Swiss weighs in:

Dear Lennard,
We recommend the following:

Rear wheel
Drive side-Outside spoke is pulling spoke
Non-drive side (disc wheel)-Outside spoke forward (braking spoke)
Front Wheel (disc)
Both outside spokes forward.

The reasoning behind doing it this way is that we believe that the spokes undergoing the most dramatic changes in tension should be the ones that are those that lay across the hub flange with the heads "in". This factor is not mentioned in Dan's letter and is often not considered. It is the changes in tension that lead to spoke breakage, and if there is more contact between the spoke elbow and the flange, there is less stress on the spoke elbow. Also we believe there is less damage to the drive side spokes if the chain falls off the large cog. Our wheel guru, Gerd Schraner, puts the pulling spokes heads-in, elbow out on all rear wheels, drive-side.

I do it elbows in because that's the way I learned and was told makes for a better wheel. That said, I've never heard of a wheel failing because the trailing spokes were elbows out.

There is that fact that if a chain drops in between the cassette and spokes, it can get pretty jammed in built the "wrong" way.

The argument that the pulling spokes might pull the spokes into the der is one that I've never seen happen in real life.

There is no advantage to the "wrong" way and at least one possible reason against it so I see no reason to deviate from the norm.
