7sp rear der on 9sp?

:-P

AFAIK, the cable pull will be a bit different. Any 8/9 spd Shimano
compatible rear mech would work fine.

shouldn't the 7sp rear der work ok with 9sp downtube shifters? the
cassette and shifters are new 9sp, the rear der is 105 7sp.

The 105 ders are all SIS-compatible; it will work as long as the 9sp
shifter is also from Shimano.

No, it will not. For example, I am using a first generation, "six
speed" 105 RD on an 8 speed cluster with 8 speed bar ends.

AFAIK, *any* Shimano SIS RD with the exception of the RD-7400/01/02
will work fine.

It's fine (provided the 7sp mech is in good condition with no serious
slop in the pivots; 9sp is a bit fussy at the best of times).

No [censored]? I thought cable pull changed after the 6/7 speed era?
Coolsies, something good to know if I fix up another thrifter. I've
already figured out how to grind new hyperglide cassettes to fit an old
6spd freehub.

I rode 7 speed 105 with downtube friction front and indexing rear back
around 15 years ago, and I swear it was less tempermental than the new
kit.

Yup, 9sp Shimano is temperamental. 10sp is supposed to be an improvement.

Yep, you can often get a near mint 6/7 speed SIS RD for literal peanuts
'cuz some folks think they're "obsolete".

So you'll have a HG 6 SP cassette??

Keep on saying it, eventually, you might believe it. ;-)

yes. Remember the early cassettes circa '87? They were Uniglide with
twisted teeth and the last cog scewed onto outside threading to serve
as a lock ring. The splining is the same except the modern cogs have
one large tooth as rotation when installing matters with the new ramped
cogs.

I redid an old Rockhopper a while back with those awesome old Deore
thumbies and a 6'er in back. Fresh Hyperglide cassette crafted from a
broken apart Sram, and new HG chain made that sucker shift like buttah.

You can get 7spd HG freewheels as well and improved the shifting of
even older bikes.

I've got a single speed with drop bars and campy ergo copy levers. 😄

My new city ride, however, has those Shimano flat bar shifters. The
right one works just great, but indexing front? Blurgch.

Might have to put a friction thumbie on it, regardless of how it looks.

Seems alot of trouble....unless you wanted to keep using your 6SP
shifters, I guess. Otherwise, swap out to an 8/9/10 SP cassette body
and go easy on yourself.

Ah, so you wanted to find a way to keep using those Deore thumbies. Now
I get it.

Yep, done that. But I still have a couple of DA (Uniglide) 7SP FWs, and
they shift awfully nicely, too.

IMO, front indexing was/is one of the all time bad ideas. Getting
better, true, but still fraught with limitations in terms of FD and
chainring choice.

The UG freehub is not compatible with modern cassettes and I didn't
want to swap out the freehub body. Heck, I don't even know if you can
fit a modern freehub on an old UG hub.

It was a quick and dirty job on a $15 Rockhopper + $40 in parts that I
flipped to a needy commuter for $150. He got an old bike with mostly
new drivetrain, slicks, fenders, rack and basket, and I got some [censored]
out of the garage. A good deal for everyone.

Too bad it was 4" too small for me. :-(

Nice. I advised a lot of my friends to buy Rockhoppers starting around '89.
For beginning mtn bikers I recommended them up until the mid-90s, don't know
what I'd recommend now.

Except in the earliest examples, yes, you can. For example, in the last
year, I fitted an 8/9/10 SP freehub body on an NOS ca. 1988 6 SP Deore
XT rear hub.

I can definitely tell the difference in shifting between my 7sp HG wheels
(smooth) and my 7sp UG (not as smooth). But the UG wheels are nice 600 hubs
with Open Pro, while the others are much cheaper and are the wrong colour
for the bike...

Main other difference is that it's a triple with 28/38/48, and the HG
cassette goes to 11T at the top which is more than high enough, while the UG
only goes to 13T or maybe even only 14T, which just isn't enough I'm
finding.

I did it to a first gen 105 hub, 6sp UG to get to 7sp HG.

The old steel frame ones were rock solid (sic). 😄 I do love the old
Deore drivetrains, to the point, affordable, and with those thumbies I
just love. The old Deore hubs were as smooth as Ultegra stuff today
after a repack. The U-brake's pretty stupid for off road, but for a
commuting conversion, they're great and don't get in the way of
panniers and other strapped on bits.

It was a shame that one was too small, but after I built it a custom
cassette, 13-26, and added some of those 1.25" Performance slicks, it
was a sweet city machine. Only bad thing visually were the too wide mtb
fenders. Too bad you can't find 26" fenders in 45mm wide.

The travel is the same.
On older (6) derailleurs, the body may not have enough
travel laterally. Going the other way ( new changer, 7
system) one may need longer limit screws.

It will be fine. I'm using a 7-speed XT RD with a 9-speed cassette and
shifters.

As long as it's not worn out, it will work fine. The only shimano RD
that was unique, was DA 8s, all others, road and MTB are the same
geometry-

With the proper flatbar road FDfrom shimano, it will work fine with any
crankset. NOT a STI road FD and NOT a MTB FD.
