My tourist (due to the short head tube) only allows the stem to come up 1.5inches which is 0.5 to 1 inches too short for me for really long rides.

I could buy a new quill stem but then I saw really well reviewed quill extenders like this https://www.amazon.com/Sunlite-Cromo...quill+extender

So essentially there are now two interleaved tubes to control your bike. Any thought on this in general and how this will hold up if I have 20 pounds on the front panniers?

there is not that small an increase.. Lower ID shoulders against top of fork steerer..

Then the quill stem goes inside, so whole length of the quill is effectively above the top of the fork steerer.

load in the panniers , not on the handlebars, right?

this isnt a threadless headset fork, right?




'/,

i've got a similar quill extenders on my bike now.
(not enough fork tube exposed to bolt stem onto)
extender is locked into the fork tube, and have a riser
bolted onto that.

thousands of km's, some with front bags. it's solid.

not sure if this is the same.....seems like this one goes
into the fork tube, then the old quill is inserted into the
extender. not for converting quill to ahead stem whatsit.

check the comments on the amazon page.
this one gives you MINIMUM 4" rise.

can also get adjustable quill extenders....in 22.2 or 25.4

I have this exact extender on my Robinhood. Once everything is tighten down, it is rigid enough. You will need a very long hex wrench or a hex bit on an extension to tighten the bolt of the extender to the steer tube. Then you attach your stem as usual.

Alternatively, you can replace your current stem with this long one. It is steel so it is heavy but it might be lighter than the extender + original stem combo.

I personally would go with a stem with a long quill. I just don't like using adapters of any kind, aesthetics being one reason.

I suspect the 8.25" rise stated on Amazon is in error. That would be too extreme. Harris Cyclery website says it has 140mm (5.5") rise from minimum insertion line. Total length is 210mm (8.26").

Pictured is my Dimension riser providing up to 4" rise above headset. It works fine and I think looks cleaner than the stack of spacers used with a threadless headset...

I dont have the threadless adapter you linked as its steel. I have 2 aluminum ones though. 1 by Dimension and 1 by VeloOrange. Both are fantastic.

Both arent noticably flexy or anything. Its basically just a metal rod that goes into your steering tube, nothing groundbreaking or complex.

The only concerns are weight and finish quality.

You would need a threadless stem to use the threadless adapter. That is convenient because you can then get a stem with a rise and length which best fits you.

A quill to threadless style stem adapter makes more sense. Much easier to swap out different clamp on stem sizes if need be to tweak the fit.

edit: The tightening bolt on my Dimension riser/adapter extends to the top of the riser and is tightened with a normal length allen wrench.

A "quill extenders" as mentioned in OP has the tightening bolt way below the top of the extender. Usually it is slight above the step between the 22.2 mm to 25.4 mm. Otherwise, the normal quill stem would not be able to go into the extender.

Yes, a threaded (quill) to threadless adaptor has the tightening bolt on the top. Then you would have to buy a threadless stem, usually doubling the cost of the entire modification. I have the longest available on the market (Soma) on a small frame Trek 520 Tour and it is still a very rigid setup.

The simplest is, as mentioned, to replace with a longer quill stem. If steel is too heavy, then the long Nitto is good, but at more than twice the cost. There is another in between (length wise) option. It is a Kalin and 220 mm long, not quite the 250 mm, and is lighter than the 250 mm steel one.

For my threaded stem mtb conversions, I use these for 1" quill stems with a 35 degree long stem.

For 1-1/8" quills, no good quill stem adapter exists with a rise over 1". I use these instead.

Inpd, If you only need 2-2.5 inches of total rise all of the above suggestions (except saddlesore's) may be too tall, even my 4" adapter suggestion. See the photo of my really short head tube above. The riser is bottomed out in the steerer tube with 4" exposed up top. A shorter riser/adapter (Nashbar or others) would bring mine down to 2.5" if I wanted it there...

The Sunlite riser that you link to may also go higher than you want. Depends on how long your "short" head tube is to use up unneeded rise. Looking at it's dimensions on the Harris Cyclery link I'm guessing that it provides a minimum of about 4" of rise before adding your existing stem to the top.

I have used the Part the OP listed as a Quill to threadless adapter , combining it and the stem shim,

To go from 7/8: bottom , 1" top, and the shim to 1.125" OD, then the quill riser being hollow Put a cork in the top.

The tube is chromoly steel rolled down at the bottom, where it's OD is the ID on top.

Nashbar ATB Comfort Quill Stem

This has a 40 degree angle so the 110mm stem raises the bar 7cm and does not change the reach over the existing 90mm 0 degree stem.

I have used this one also. Works as well as the sun lite one I suggested but does not look as polished. It looks a little chunky but got me the height I needed to raise my handlebars on an old GT conversion I did a few years ago.

I used a Nashbar quill adapter with a threadless hybrid stem that I already had. Gives me the perfect height on the RB-T. I can get an additional couple of inches with a quill extender but that gets kind of clunky-looking.

Here are the two I have used.

It seems its 180mm but you seem to be using the quill beyond its intended limits (i.e. the ||||| marks on most quill stems)

I am at the upper limit but the minimum insertion marks are not visible.

I would recommend an adjustable stem where you can change the angle. I bought one 5 years ago with the intent of using it to figure out my best ride position and reach. I figured once I got it dialed in I would buy a new quill stem to those dimensions. Mine even has degree markings on the side and is easy to set and very secure. What I found is spring to fall when I’m riding a lot I start to want to lower and extend my reach. I have also found mid ride on a long ride I sometimes want to sit a bit more upright and it only takes a few minutes to set and then turn the bars down to level again. The weight penalty on a touring bike for me wasn’t a big deal given the convenience.

The thing about setting more upright is your arms stay the same length so the arc change brings the hoods right back with you. The stem angle also brings the bars back. So you can find a combination of the two to be perfect.

You might have to change your cables to be longer also.

In the photo I am using a Quill to Threadless converter but I am not sure if that is the correct name or not. The frame is from 1961 or 62, used to use a quill stem. But I put this adapter in so that I could put a threadless stem on it. Works fine.

I made the change because I wanted to be able change the reach while I was dialing in the fit, a threadless stem with removable face plate allows me to change stems in minutes to change reach. The regular quill type stems did not offer that ability to make a quick change.
