Hi all
First time post so go easy!
Im really keen to keep using my 10 speed wheels which have CK Classic hubs on my new 11sp clad roadie. CK dont do 11sp conversion kits for the Classics, and they dont do Campag Freehub bodies either.
I found a solution as per this link (Lasco Concepts) where an 11sp cassette is machined to fit a 10sp hub. Im not keen on running the cassette with 10 cogs. Does anyone know of a Lasco Concepts type solution locally in Australia, or even Melbourne?

Not sure if I've read your comment right, but you will still have all 11 gears on the back.
The alternative is to machine a small amount off the right side edge of the left hand lip of the CK freewheel, but this will be much more difficult, or to replace and relace with a new rear hub.
I'd go with this.Lasco Concept is able to modify many 11-speed Shimano and SRAM cassettes (except SRAM Red one-piece cassettes) with a 25T minimum large cog. Precision machining of the cassette is done on a lathe, a tiny amount of material is carefully removed from the back the largest cog carrier. The result is that you get perfect Shimano or SRAM shifting with the use of all 11 cassette cogs on your 11-speed drivetrain.

Was just wondering if there was any one offering a similar service in melbourne. Machining the cassette definitely sounds like the way to go.

The small inconvenience is that you have to do it every time you replace the cassette.
The other option is to run with a wall-climbing Shimano HG800 (non-series Ultegra-level) 11-34 cassette with R8000 Ultegra rear derailleur. The back of the cassette is dished out, so it fits on a regular 8/9/10-sp. hub. It is for this reason it has its own model designation rather than being a part of the R8000 cassette range.

If not plain impossible.... The lack of Campagnolo-type freewheel body option, which is longer than the Shimano 8/9/10-sp.-type, suggests the possibility that the "shoulders" at the base of the splines sit only slightly proud of the hub shell flange, leaving no room to shave off the necessary 1.85mm.trailgumby wrote: The alternative is to machine a small amount off the right side edge of the left hand lip of the CK freewheel, but this will be much more difficult
I had a thought, but it got run over as it crossed my mind.

If you just want to use your nice wheels, another possible option, if you don't use the 11 tooth cassette cog is to just remove it and get a 12 tooth lock ring. You might even need the 12 cog from a donor cassette. Probably need to find an extra spacer too (maybe all from a donor cassette).

Excellent idea ... and good point. For the freehub machining option, do you know how much would be required? The figure of 1mm is floating around in my (empty) head, but I'm not certain of it.Duck! wrote:The small inconvenience is that you have to do it every time you replace the cassette.

^^ Exactly. The difference in spline length between 8/9/10-sp. & 11-sp. is 1.85mm..

Yep, that's rather a lot of excess meat to find on a 10s hub. My 11S rear wheel came with a 1mm spacer. Some of the difference must have been made up at the other end.

I machined 1.8mm out of my 11s cassette to fit on a 10s hub. Easy if you know a machinist.
