Chris King Alloy Drive Shell

[Dave]

What are people's experiences with the Chris King alloy drive shells? I
have a stainless steel one, and I'm getting another set of CK hubs, and
wanted to know what the alloy ones were like.

Thought, opinions?

Many thanks,
Dave

I'm interested in this too. Also, does anyone know a good international
dealer for CK hubs? What should i expect to pay, and are skewers included?

Regards

Bow

I use Chris King for road, touring, and MTB. The aluminum alloy driv
shell works OK as long as you use cogs that are mounted on carriers tha
help spread the load. I tried a MTB cassette with the largest 2 cogs o
a carrier once, and that distorted the carrier such that the shiftin
degraded. The carrier had significant impression from that venture.
wouldn't try it again with any less than 3 cogs on a carrier for th
large cogs. If you already have the stainless steel one I would keep it
I know there is a weight difference, but it isn't worth it to me

As a side note, Shimano's 10 Speed DURA ACE cassette is has deepe
ridges/valleys to handle the load on the 10 speed hub

Actually, I believe the reasons for the taller ridges on the hub is to
prevent the use of loose sprockets. This is because the new Dura-Ace
hub is the first Shimano hub to use an aluminum Freehub body. Such
bodies are notoriously inadequate for use with loose sprockets in the
larger sizes. The soft alumiuum gets notched up and it can become very
difficult to remove the sprockets.

Personally, I consider aluminum Freehub bodies to fall into the "stupid
light" category of parts.

On the 10 speed DURA ACE hub, the one with the aluminum alloy casett
body, you can't fit any current cogs except the DURA ACE 10 speed. Tha
certainy does what Sheldon says. The deeper grooves also provide mor
surface to spread the load on the softer material. I guess weigh
savings drove them to it. I see the front hub is acutually heavier fro
9 to 10 speed however. Score 1 for marketing and 1 for engineering. O
the Chris King side of the story, using a 9 speed DURA ACE cassette
which has the largest 3 cogs on a carrier, makes only small "nicks" i
the ridges of the aluminum drive shell. I pull the cassette about ever
1,000 miles to give it a dunking and complete cleaning. When I do that
also clean up the "nicks" on the ridges of the CK drive shell
Everything has been working well for over 30,000 miles on one CK hub.
do regular maintenance on the hub, including the ring drive and "O
rings. I use Chris King lube made for their hubs. I have similar result
with a 9 speed XTR cassettes on my touring bicycle, but only 16,00
miles on that hub. If you want the Stainless Steel Drive shell fro
Chris King you will need to wait for 30 - 45 days as they are out o
stock. Note that not all Shimano cassettes have precisely the sam
width. Some are undersized enough to be loose on the drive shell. If yo
find one of these, there are thin washers ( 0.5 to 1.0 mm) to tighte
things up. Proper torque and grease on the lock ring threads is alway
called for
