Garth said: "there should not be any wiggle at all, as in zero. Stems 
shouldn't move when tightened, like seatposts."

This is just not the case.  Quill stems are not like seat posts*.  
*Threadless* stems are more like seat posts.  With quill stems the stem HAS 
to be undersized so you can get it inserted in the first place.  The 
"clamping" interface is sunk down deep, so there's still slop up top.  With 
seat posts and threadless stems the clamping interface is up top.  

A small amount of wiggle is normal.  The less there is, the better, to be 
sure.  

*There was a small historical anomaly where seat posts are like quill 
stems: Briefly the seat post maker SR made a seat post briefly that clamped 
with a wedge like a quill stem.  It was OEM on some bikes in the 1980s. 
 Google "Schwinn 564" and click "Images" and you'll see one of those 
models.  That Allen bolt in the side of the seat post actuated the wedge. 
 It was terrible.  The seat post creaked because of the wiggle.

Re: [RBW] Headset adjustment

2023-09-06 Thread Richard Rose

Also & regarding Garth’s comments regarding the possibility of this Clem L being too small for me; Mine is a 52 & “should” be correct for me according to Riv sizing suggestions. I have put nearly 6,000 miles on this bike and dearly love it. But, I think I’d have been very comfortable going one size up. That would have put me on a 700c bike instead of this 27.5, and likely would have required a shorter stem inserted a bit deeper into the head tube. Proof of concept I suppose is that I am quite comfortable on my size large Gus. Not really more comfortable than on the Clem - but equally comfortable. The joy of always being in between sizes! Needless to say there is zero flex up front on the Gus being 1-1/8” threadless. Both bikes are a joy to ride.Sent from my iPhoneOn Sep 6, 2023, at 7:36 PM, Garth wrote:Okay, I see what's happening :) Richard, the min insertion for a stem is always marked on the stem, and it's to the top of the lock nut.

This pic shows how far into the head tube my stem currently extends. The 
minimum insertion line is 2 cm below the lock nut. FWIW, I do not notice 
any movement riding the bike. I only notice it straddling the bike, feet on 
the ground & putting my full weight into the grip area of my Bosco bars.

You know, Bill… after reading your comment here I had to go take a look at
my Appaloosa and wouldn’t you know it, you’re right! There’s some play in
it! It’s not as pronounced as the video Richard shared but it’s there to be
sure! I’d never noticed it before. Perhaps the others are in correct and
what is needed here is a taller stem to allow for more to be inserted in
the steerer.

Okay, I see what's happening :) Richard, the min insertion for a stem is
always marked on the stem, and it's to the top of the lock nut. The min
insertion line on my stems on hand range from 6.5cm for a relatively short
Nitto quill adapter to 7.5cm for taller Genetic brand one. My tall Nitto
Faceplatter stem is about 7cm.

2 cm below the lock nut is quite insufficient, as in "Danger Danger Will
Robinson !" That "may" explain the wiggle, not being in far enough. When
it's in to at least the min insertion line there should not be any wiggle
at all, as in zero. Stems shouldn't move when tightened, like seatposts.

If your stem isn't tall enough, tell me exactly which one you have. I have
an unused Nitto HighRiser, the original ones Riv had made in 135mm
extension @10 degree up and a 31.8 clamp that I'll see you if you need it.

Re: [RBW] Headset adjustment

2023-09-06 Thread Bill Lindsay

Since you've measured your stem at 22.2mm and since you perceive the same 
wiggle with two stems, that rules out an undersized stem.  That gives you 
two choices:  

-live with it.  It's one of the minor shortcomings of quill stem bikes, 
made more noticeable with a really tall stem and presumably wide bars.  
-OR-
-pursue the notion that your steer tube inside diameter is larger than it 
ought to be.  

If you wanted to pursue the notion that your fork is "out of spec", try 
inserting one of your test-stems into another 1" fork steer tube and 
convince yourself that it does not wiggle.  Then you will have proven there 
is an objective shortcoming on your fork.  Talk that over with Rivendell 
and try to make it right.  

In general, every quill stem, when slid into the steer tube has a small 
amount of 'wiggle'.  That small amount of wiggle is reduced but not 
eliminated by tightening the bolt that engages the wedge.  That wedge-spot 
is down at some depth, and the stem can still pivot around that point a 
tiny bit.  That is the way it is, to some extent.  In the case of a steer 
tube whose ID is larger, that wiggle will be larger.  I don't know if 
Rivendell has a spec that they guarantee, nor do I know if there's some 
universally accepted tolerance there.  My instinct is that the steer tube 
ID has to be larger than 22.2mm, and I'd say it probably also has to be 
larger than 22.225mm (which is the real value of 7/8"). To me, 22.3mm seems 
reasonable.  To me, 22.5mm would seem unreasonable.  Where to draw the 
line...22.4mm?  I don't know.  

For the sake of science I just tried to wiggle the stem on two of my bikes 
that have a 1" quill stem.  On neither do I consider it a problem.  On one 
bike (Bridgestone RB-1), I could see the gap around the stem at the locknut 
open and close ever so slightly.  On the other I saw no change.  What I see 
in your video seems like "more wiggle" than either of my test bikes.  Take 
that for what it's worth.  Maybe have a mechanic you trust give it a look. 
 Tell them "I think this is bad, what do you think?  If they say "yeah I 
agree it's bad" then pursue something. If they say "no this looks normal" 
then maybe live with it.  

At any rate, if the wiggle makes you unhappy, talk with Riv and find a way 
to be happy.  I'm sure they'll work with you to get you there.

Re: [RBW] Headset adjustment

2023-09-06 Thread Ted W

Couple of thoughts right off:

1. if you pull the stem out to the minimum insertion line and re-tighten
it, does it still move? Sometimes, if you've inserted the stem too far, you
may encounter this issue. It can be mitigated by getting a shorter stem or
cutting the current one down a bit (advanced mode).
2. What's the inner diameter of the steerer and what's the outer diameter
of the stem? There are different threaded headset standards. I've provided
a summary below. It's possible you've wound up with a mistmatch:

*Stem “neck” outer diameter* – measurement units: mm (inches)  *Standard
name*
*21.15 (13/16″)* Old American and BMX standard
*22* Old French standard
*22.2 (7/8″)* Standard for most threaded forks with an outer diameter of
25.4 mm (1″)
*25.4 (1″)* Standard for most threaded forks with an outer diameter of 28.6
mm (1 1/8″) – not very common

Greetings folks. I would appreciate any input regarding this. Since new I 
have had some movement in my headset / stem that concerns me, possibly 
unnecessarily so? Please review the attached video link and tell me what 
you see. I felt the headset was a bit loose so tightened it a bit. This 
made no difference. The minimum insertion line for the Faceplater stem is a

Re: [RBW] Headset adjustment how to ?'s...

2017-10-13 Thread Eric Norris

Lum:

Here are two things that I’ve learned:

Be careful and don’t tighten it down too much. You can damage the races.

That being said, tighten the adjustable part just a bit beyond where the play 
in the bearings is removed, then lightly tighten the locknut down, and finally 
loosen the adjustable part into the locknut. In my experience, this works 
better than getting the adjustment right and tightening the lockring.

As always, the late Sheldon Brown has his own advice:

[RBW] Headset adjustment how to ?'s...

2017-10-13 Thread lum gim fong

This is a needle bearing IRD Rollerdrive just like Riv sells.

1. Loosen lock nut
2. tighten the nut under the spacers 1/8 turn
3. Tighten lock nut.
4. test for correct feel.
5. Readjust if.


Is this right?
Anything to look out for?
Do I have to worry about those keyed spacers or anything else that might be 
keyed I have to be careful of?
Or is this just as easy as described above?

Re: [RBW] headset adjustment

2016-11-06 Thread Patrick Moore

My Rivs have all had 32 mm flats on the headset bits. I'd get a 32 mm
adjustable cup wrench, and spend the change on a big, decent quality
adjustable wrench which is also useful for bb assembly removal and hitting
the dog. (And for many other things; just kidding about the dog; he's
already cowed and obeys me implicitly.)

[RBW] headset adjustment

2016-11-06 Thread Joe Bernard

Yes, all 1-inch threaded headsets use a 32mm adjusting nut. You only need one 
32 wrench for the adjuster, the locknut can be snugged down with a standard 
crescent (adjustable) wrench.

[RBW] headset adjustment

2016-11-06 Thread Jim S.

Hi all,

I was going to attempt a headset adjustment, which I've never done. I need 
to buy two wrenches to do the job. It's probably obvious to others, but I 
can't figure out what size wrench to buy to adjust the headsets on my 
Rivendells. Are they all going to be 32 mm? That appears to be the most 
common size. 

Thanks in advance for any answers.
