Well, SRAM have two different lines of twisty shifts, their own proprietary
system ESP that works with either Sram or Shimano front mechs and only Sram ESP
rears, and ones that are completely Shimano compatible.

Right! Most people around here don't know that - they thing Sram only
works with Sram R.derailers...
2:1 trigger shifters look good.

Thanks,

PS - I've found some "old" XT 8 sp shifters online.

well, if this is on that level you could attempt to quantify use times
and conditions for each cog - not hard just cog think

bulding your own should eventually give a wide sweet spot

Then again, either getting specific size cog, or making one cassete
out of 2, just might give me my "sweet spot"

Just been at Sheldon's page - http://sheldonbrown.com/k7.html#custom -
and likelly will give it a try.

Thanks,

Something else came to mind: can I mix road cogs (from an 8 spd
cassete) with MBT cogs (also from an 8 spd cassete)??

There's no such thing as a "road" sprocket or an "MTB" sprocket.

Tha's a false distinction fostered by the marketeers.

Hi Captain,

I was wondering, if the fact that most of the cog are held together,
by screws, or something else, helps distribute the load by the hbu
part where the cassete seats, and how that distribution would be lost
if you break the "bond" between most of the cogs, and therefore put
abnormal pressure on both the cog you're using, and the small part of
that where that cog seats, as compared to distributing that pressure
by most cogs, and the most of the hub where they seat...

Does that sound clear?

Anyway, the fact that the last 2 or 3 cogs are not "bond" to the rest
of the cassete ruins my theory ... or is that just a error in the
distribution of efford concept??

Cheers,
jbr

Personally, I think they should have stopped at eight if not seen.

But That's Just Me.

I'm going from 8 to 9 on my cross bike. We'll see how I feel about it. I
actually race it and the extra cog could mean something. The parts availability
for campy stuff and it's ability to use a shimano cogset made that call.

My mountain bike's 8 and gonna stay that way and the road bike is seven which it
will be from here onward. The beer bike's a 3x6 and not likely to get an upgrade
unless it becomes less expensive than keeping it the same.

It's clear, but it's another imaginary problem.

This is an issue if you're unwise enough to buy a hub with an aluminum
Freehub body. That type of hub needs to have the larger sprockets on a
_spider_ module...just having individual sprockets bolted together
doesn't distribut the load significantly.

You might benefit from reading my article on Shimano Cassette Hubs:
