Hey guys,

I'm having a hard time finding an 80mm 45 degree stem. I'm somewhat new to biking, so my question are: (1) does anyone make this stem and (2) do you know of anywhere it's in stock? I can find 80mm 35 and 90mm 45 everywhere, but I can't find 80/45!

Thank you

Those are on the shelf right underneath the hen’s teeth.

You're going to struggle to find an 80 mm stem at 45 degrees.

Why not just go for one of the Ergotec 90 mm stems? A few of these would work just fine.

I will look at them, but I have a short torso and very long legs. I really think I need the 80mm. Right now I'm on 80mm 35 degrees per the bike fitter's recommendation, and it's just a little off - could use a few mm of reach reduction and a few mm of stack.

Are you already using a steerer extension?

If not, you might want to consider one instead of need a 45* rise.

I would guess and 80/45 probably has the same reach as a 70mm without that much rise.

I asked about that, but they said it's a carbon steerer that's actually attached to the fork.

Is it just impossible to manufacture an 80/45 due to the angle or something?

Troul 

might be possible to change the bars out to something with a slight rise built into them & fit it with the appropriate stem from there?

Soma Condor 2 fits the bill and would probably be better for a carbon steerer.

I did a quick search and You can get a 75mm 40 degree (Profile Design) or an 80mm 40 degree (Satori).

What about 80mm 40 degree stem?

Procraft SL 31.8 Stem 40° comes in lengths of 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm and 130mm

TheFort

Great, thank you. I'll put it on my watch list.
It looks like it reduces reach 6mm and raises stack 4mm when compared to my 80mm 35 on the bike now. I just need a little more comfort, so this might do the trick.

That’s one of the wildest collections of stems I’ve ever seen.

I can’t help but think there’s a significant bike fit problem here. I’ve never seen an outlier part installed on a bike that wasn’t some kind of work around for an improper fit. I don’t know the details, but this one seems odd.

Ritchey makes a an adjustable 90mm stem which can go to 55 degrees. Remember the sharper the angle (upward) the closer the stem will be.
Also remember that 80 mm@ 45 my not be the perfect setting.

TheFort

As I mentioned above, super long legs and a short torso. I have a 34.5" inseam and I'm 5'9. That's the outlier!
To add to the problem, I want to be in a recreational/touring position rather than a race position.

Have you tried the stem comparison tool? When you start getting into high rise stems it's helpful, the reach numbers are often different than what I thought I was getting. Also after 45degrees extra length can just be bonus stack height.

Yeah I have seen that. It's very interesting. A 90mm 45 degree stem actually has less reach(-7mm) and more stack (+16mm) than my 80mm 35 degree stem, which is counter-intuitive. I might try a 90/45 since that's about what I need in terms of reach reduction and stack addition.

...it's too late this time, because you already have the bike. But this anatomical configuration (longer legs and shorter torso), was the reason for the design and sale of the old "women's specific" bike frames. Like the ones made and sold by Terry. Just as an FYI for the future. I think you can still find those around used, but the new ones are all custom. If you're going to spend the money on a custom frame, any builder will fit it to your unique anatomy.

A lot more practical to figure out your stem workaround.

I know you've probably tried this with the fitter, but I'll ask anyway. Is the saddle all the way forward and are you using a zero setback seat post ?

They are ugly, and also heavy, but an adjustable stem would do what the o.p. wants. I do concur, however, with any opinion that suggests that there really is more than one way to skin this particular cat. The laser focus on an 80mm/45deg is hindering any thinking outside the box.

TheFort

The seatpost the bike came with had a 20mm offset. So i just changed that out yesterday for an inline/zero offset post. I've only done one ride in that configuration, but it was pretty good. The saddle is now in the middle of the rails instead of on the back end, too, which is probably safer. I could move it forward a little, but I don't want to get ahead of the pedals.

If I ever get another bike it will be custom now that I know my anatomical shortcomings better.

This stem from VO would meet that latter requirement. https://velo-orange.com/collections/...py-stem-31-8mm

I've played that game, don't compromise saddle position for reach. Get the saddle right first, then do whatever needs to happen to get the reach right.

Why not an adjustable stem? Weight issues?

If not, I've installed plenty of them for clients, and they love it.

Most suburban folks buy mountain bikes because they look good and status, but ultimately just want to ride upright like a commuter hybrid bike.

I've used those high angle stems for years. Most drop bar bikes come with the handlebars lower than I want them.

That stem is basically identical to an Ergotec High Charisma as, per my link above.

If you switch to touring bars, you will handle all of the fit issues without breaking a sweat. Now, there would be different brake levers and shifters needed, assuming you have brifters now.
