10 sp cassette for Shimano Hub/Campy Shift

[Sailor Mur]

Does anyone know whether a Shimano 10 sp cassette or an American
Classic 10 will work best on a Shimano 9sp hub and Campy 10 Ergo?

And we all believe in the tooth fairy as well...without servo assistance, such as in the Scott and Suntour SE brakes, the only way to get a higher force at the brake pad for a lesser force at the brake lever is to increase the mechanical advantage by decreasing the travel of the brake pad for a given lever movement. This means the brake pads have to to be setup extremely close to the the rim, or the lever bottoms out on the handlebar before full braking is achieved, and also means that any runout in the rim causes it to rub on the pads without the brake being applied.

The problem you are running into is that the S10 hasn't been out long enough for cheap bastards like me to actually go out and buy it. Since us cheap bastards haven't bought S10, we won't know for sure how well it works in a bastardized setup.

I do know that C10 shifters and rear derailleur work well with an S9 cassette.

I can guess that S10 is going to work fine with any of the C10 shifters/rear derailleurs.

I still think that the ultimate setup is Ergo shifters and rear derailleur, with Shimano everything else.

I thought Vecchio's knows everything about bikes?

Anyway, DA10 does fit on a Shimano 9 freehub. It includes a 1mm spacer which sits on the inside before the cassette is placed on.

1. Better braking, requires far less hand strenght to get equivalent stopping power.
2. The quickness and accuracy of shifts are far better.
3. Front derailleur stiffness. When you pop that puppy up or down it goes without hesisation, no flex, and no adjustment has been necessary since installation.
4. Stiffer crank. You can hammer as hard as you want, and you'll get no flex into the front derailleur.

DA10 rocks. I've been on it for two months now. Outperforms everything else, campy record included.

Diatribe on the virtues of campy as you like, but a square taper BB is pretty ancient stuff....

Stop and think. A stiffer crank would only serve to make the front derailleur flex more. It is frame flex that causes the front derailleur to rub the chain.

BUT, the original question of this thread is which 10 sp cassette works best on a Shimano hub with Campy 10 system.

I worked on a friends bike with the DA 10sp group. It had the 10 sp cogset. I put the wheel into my bike for several shifts and found that I'd have to adjust the derailleur stop and lose a little cable tension to make it shift ok. The rear derailleur was a Campy 9sp
Record.

I tried making a 10sp cassette using Shimano cogs using 2.3 mm spacers between the cogs. The 1.8 mm cog plus the 2.3 spacer was 4.1 mm, which is what Campy called for. I could not get the small cog onto the hub body. Looking at the Wheels cassettes, they all start with an
11t cog and I didn't try that but my guess and calculation is that it won't work. I may have to put a 2 mm spacer between the largest 2 cogs.
