I saw this slammed Technomic on a bike for sale here.

I offered to trade the guy a 2 years old Nitto Dynamic + $15 for it because I'd like a tall stem and I've never seen one around before.



This stem will be taller than my Dynamic/ Cinelli 1A right? Does anyone know by around how much? It might be kinda old and i'm not sure if they changed the length or anything.

I've had older cinelli stems break on me. Is it crazy to trade a nitto i bought new for an older stem?

Also, it's on a 52cm bike. Wouldn't it be gripping the butted part of the steerer slammed like this?

Is the technomic a good quality stem?

Thanks guys.

Not sure but I think good strategy would be to ask those questions before offering.

The Technomic is most commonly a very tall stem but has been made in two heights, IIRC. How much taller then some other stem is hard to say without measuring. Additionally steerers have a butted section with a smaller ID at some point as the stem fits inside the steerer that can prevent a stem from inserting beyond a set point. Lastly the clamping diameter 9of the bars) can be either a 25.4 or a 26.0mm. It's prudent to not mix the fits.

Seems to me that the answers are easy to discover without involving the world. Andy.

There is a Technomic and a Technomic Deluxe. The deluxe is shorter, cold forged, has a nicer finish and is more expensive. the lengths of both can be found online. The Technomic shown above may have been shortened. I have shortened a couple of Deluxes.

Ben's cycles is a great source for nitto stems and handlebars. The measurements can be found on their webpage. Universal cycles also has measurements and carries a pretty good selection of nitto stuff (not as good a selection as Ben's though).

If a stem is mounted that deep into a 52 cm frame, I've got a feeling it's not a very long stem. I generally ride 54 cm frames and can't get any of my average-length stems seated that deeply before they bottom out.

IDK, maybe they sawed it off short and used a shorter bolt just to do that slammed low bars thing./.,.

That Nitto Technomic is not full length if it's that deep into the head tube. That head tube would have to be very long to swallow that up. I'm pretty sure it's been cut. I usually leave 2.5" of system in as safety and even then a full size Technomic sits 5-6" above the locknut.

I hope this isn't a silly question but why not just pull it out and look at it?

I tried that suggestion. Andy.

Thanks all.

I should just go and look at it to see. Nitto stuff i've had has always been very good but if it's been cut i'll keep my dynamic. I didn't even realize you could cut quill stems.

I am just being lazy!

Maybe someone can answer me an easy question so i wont start another thread.

Do the steerer tubes on threaded 1" forks have to be the same length? I'm changing out a bent fork and the one I want to use is a bit longer. The headset is a Rudelli needle bearing one that came stock on my F Moser Forma. I have a sharp hacksaw but no pipe cutting tool.

The bent fork is the nice chrome one. It's about 3mm difference

For some values of bit. You can either cut it or make up the difference with spacers. If you cut it, consider leaving it 5 to 10 mm long particularly if your headset is a very short stack.

Edit
I wouldn't cut it for 3 mm. Spacers are your friends.

Thanks.

Sorry if this is obvious, but can i still run spacer(s) with this kind of headset? The lockring is the pin spanner piece is the photo above.

It has been going strong with yearly repacking and it's the original headset from the 90's - it used to have F Moser Rudelli stamped on it.

The other important spec is how far down the steerer the threading goes. Of course it needs to be enough to house the threared portion of the headset (and cutting more threads can be a tricky and possibly damaging effort). But also where the end of the threads are WRT the wedge of the stem. You REALLY don't want the stem to be trying to split open the steerer right where's there a bunch of deep stress risers. ARS.

If i'm seeing how that headset works, it doesn't seem that you can put spacers under the lock nut to increase the effective stack height. Never seen one of those, sorry.
