*UPDATE and report:*
I swapped out the cassette for the 11-32 RBW sells, and threw on an SRAM 8
speed chain. It was really easy and fun to do. Didn't need to adjust limit
screws. Just threw it on and runs fine like the old system.
*How it effects drivetrain:*
Chain runs fine thru my Deore derail
If Jim says "works, sometimes", my sense is this is not a good idea. Seems
like the downside could be spendy.

My buddy Will used to run friction with an Alfine hub on his 650b Vaya.
Said it worked ok. Seems sketchy to me though.

I've friction shifted IGH hubs. It "works" sometimes.

Update:
I called RBW and they said it would definitely help to go to 8 speed cassette
over the 9peed.

That's been my conclusion.
I have the ability to use a 9-speed cassette,
but since have gone to an 8 speed cassette with the same spacing.

You are right. It appears that, at least for Shimano and SRAM cassettes,
the center-to-center cog spacing is 5.0 mm in the 7-speed, vs. 4.8 mm in
the 8-speed, vs 4.34 mm in the 9-speed. Good to know. If I ever try
friction shifting again, I will pick up a 7-speed cassette.

I switched from 8 speed friction to 10 speed indexed DA downtube shifters
and haven't missed a single shift since. It's freakin' awesome.

4 versus 4.5 mm, IIRC; at any rate enough to mess up indexing of 8 using 7
speed shifters (even with the "Centeron" pulley). I personally have never
tried shifting 7 with 8.
Centeron -- sounds like either a cult philosophy or else the younger
brother of Darth Vader.

You are wrong about spacing. See sheldon on this.

I'm shifting 7 in friction on one bike and 8 on another, and am happy with
the result. Old Grand Sport shifters on Riv bar-end pods on the 7 - this
combo is flawless. Campy Record friction with a Campy Chorus 8-speed
derailleur on the other. The Campy has long cable travel and a larger
cable
I originally set up my current bike with an 8-speed cassette and Silver
friction downtube shifters. I could never get the hang of it; it was just
too fussy to try to get the proper gear with no rubbing. Going down to
7-speed cassette would not offer much help, since 7-speed and 8-speed cogs

Recently bought a SRAM 830 8-speed chain on ebay for $13 shipped, and there
are plenty of vendors selling at that price - have run this same chain on
5, 6, and 7-speeds.
On a couple of bikes (8 speed friction and 9-speed index) I'm running the
PC-991 9-speed hollow-pin chain, bought for $38 at
I get the same miles --2K -- out of 8 and 9 speed chains, fixed or free,
one or many speed (Could this be due to high torque climbing?) Also, I've
had no problems adjustment or otherwise, running 8 speed chains with 9

I failed to mention another important consideration:
If you currently have 9-speed series derailleurs, you might have a bit of
trouble with an 8-speed chain, because the cages are narrower and the chain
is wider. It can work, but it becomes even more fussy because the
derailleur has to be pos
I have a couple of bikes with 9 speed setups, but mostly use and prefer 7
and 8 speed. But I do this based on a preferences for the wider, more
durable chain (that doesn't stretch and wear out as quickly as a thinner
9-speed), and for thumbshifters which are more readily available in 7/8
