Does anyone make a steering tube extender like this in 1"?

Does anyone make a steering tube extender like this in 1" ? https://www.velobike.co.nz/products/...-tube-extender
I'd like to be able to raise my stem about a centimeter.

Flip the stem or get bars with a bit of rise to it.

That'd be my preference before moving to the stem extender like setup.

Already done. Still need about 1cm.

i got a local machinist make it for me..... I would say ~75-100$ or a six pack if you know him/her
i went with solid long bottom, 1.5" deep, epoxied to steerer tube, 2" extended

If your steerer is steel, then, a local builder will be able to braze(? or is it weld?) it to any sensible length.

This is what you need. It can be shortened and can probably be found on eBay.

That's a great kludge. I'll need to source a shorter bolt and punch the star nut down, but that should work.

If you've flipped the stem and have riser bars and they're still not high enough, then try lowering your saddle.....it probably sounds counterintuitive but most fit issues are caused by a saddle that's too high. Drop it 1cm and see what happens. Pedalling might feel a bit weird at first, but give it a couple of rides and you might find it makes the difference.

An important note: The OP didn't mention steerer material, but the expansion wedge steerer extender is intended only for steel steerers - not for carbon or aluminum steerers. So hopefully the OPs steerer is steel.

Indeed it's steel and unthreaded.
I hadn't thought of the riser bar possibility, is there a set that have a profile like the Zipp SL70?

Also ...

The OP mentioned having already flipped his stem, but he didn't mention the angle. Stems are available in a variety of different angles, resulting in a fairly wide range of heights. Common angles are 0 deg., +/-6 degrees, +-10 degrees, +/-17 deg, and +/- 20 degrees, and +/- 30 deg. For example, an upward angled 8cm +/-17 degree stem will incease the rise by 1.5cm compared to an upward angled 8cm +/-6 degree stem. The caveat here is that the shorter the stem, the less rise will result from an angle change.

Check out the Specialized Hover bar. Can get it with or without a flare in the drops. I really like the non-flared version on my road bikes. 15mm rise over standard bars.

I'd do a stem boner before I'd ride with any of those extensions. A +6, +10, +12, +17 and even up from there. Add some riser bars @ 1.5cm and Bob's ur uncle.

Teeth are expensive.

You've done both?
In case you hadn't done the bars... Many come with 1cm rise. I run Ritchey bars that I quite like. Specialized has the hovers.

Looks like OP didn't fully read my suggestion up thread. You beat me to the hover rec.
Have you tried them with some flare? I love it on road bikes! I actually use the same bar on my caad13 roadie and TCX gravel bike!

This seems like a strange suggestion given that we have no clue that leg extension is the issue. What am I missing.

Some people are looking for the aesthetic of a "slammed" stem angle, but with some steerer length thrown in.

I went with a flipped ~10-degree stem on my previously-owned (and H1 geometry) Trek Koppenberg having a cut steerer.
Found a suitable stem online in the less-common 115mm length, Italian, sturdy and cheap.
I didn't consider using any sort of kluge extender.

I believe that the Hover-bars are available in some taller rises by now, I recall seeing them on some 60+ CX rider's bikes.

Lowering the saddle by anything like the 10mm that was suggested will normally have the rider "finding" the rear edge of the saddle when pushing for leg extension on hard climbs, which typically messes things up further after the rider then intuitively moves the saddle rearward. I've seen too many sorry outcomes of this sort, perhaps the result of the saddle having slipped subtly downward over time, and so often resulting in the rider also then choosing a shorter stem.
A very poor, uncomfortable and knee-stressing fit often results.

Acknowledging here that lowering the saddle a few mm can also make for a proper, better fit, if the saddle had been too high!
