ISO threadless “tall stack” stem with 80 mm extension and 0 or positive rise — for Roadeo

[Patrick Moore]

VO has a nice one but it has a -17* angle. Does anyone make a similar stem with a 0* rise or perhaps even a 110* or 115* or even a 120* rise? 

I need an 8 cm extension and a 31.8 mm clamp.

This to replace the 90 mm 30* Ritchey upjutter currently on the Roadeo that sits oddly under a 30 mm of spacers — the upjutting under a chimney looks odd, and I’d prefer to not cut the steerer.

Immediate desire for black but might eventually want silver.

Searching brings up only VO’s “Tall Stack” stem.

Thanks, Patrick

The best fit would be 8 cm with 15* rise: does anyone make such a stem? 1.25” steerer, of course. Searching does not turn one up.

31.8 mm and black.

Thanks.

Hi Patrick!

There's this bit of jewelry: https://crustbikes.com/products/crust-face-off-stem

A Soma crane seems to check those boxes, if it isn’t too tall.

I was about to suggest this. I've had good lucky getting tighter radius bars through the Crane I have since it's still so the gap is flexier than an aluminum Nitto or the like. Best, Zach also in ABQ

I have the Crane on a bike - it works great and can accomodate a Noodle but not a modern compact drop bar.   

[Will Boericke]

Forgot to add that the Crane is only 26mm clamp.  So probably un-useful for you.

Thanks, all. I’ll look at the suggested items.

Soma has a 31.8 option for the crane.

Based on Will's comment that the 26.0 version only worked with noodles, I imagine the 31.8 is a better option for compact bars, because of the bigger opening. If you're interested in compact bars, let me know and I can see if the 31.8 would work as mine is currently unemployed.

Whoa, I just saw that Nat flagged this first; Ta, Nat!

Thanks, Zach, this one is the likeliest yet when I plug the variables into JimG’s stem comparator. I don’t care for the little column nub rising above the extension, nor the single-bolt, non-detachable clamp, but I can live with those if the rise ’n’ reach are right. And it’s reasonably priced as things go now.

No need to test with compact bars, tho’ thanks for the offer. I’ve gotten 26.4 mm Cinelli Giro d'Italias into 25.4 Tioga T-bones with broad, square clamps using the penny method — steel can endure a great deal of abuse — and I daresay I can get the compacts into this thing if I stick with those, tho’ I think eventually I’ll rebuild with friction + silver and install proper Maes Parallels.
