WOW! A new stem where because the front brake cable goes through the stem you can NOT adjust the height of the handlebar once everything is connected.

To complicate matters even more; in order to use this stem you have to have a tube BRAZED inside your threaded fork steerer! From the site:

"The stem’s attachment is unusual, but it makes a lot of sense: A tube is brazed into the standard (threaded) steerer of the fork, and the stem clamps to that tube. This allows the stem to be smaller (and lighter) than if it had to surround a larger 1″ or 1 1/8″ steerer. It also means that the inside of the steerer tube is empty, leaving room for a light switch (see below).

Of course, we also made the tube that you need to attach the stem. The tube is available with two wall thicknesses: 1.5 mm for most applications and 1..8 mm for heavier riders who like their bars high (which stresses the tube more).

The tube is an easy retrofit if you have a bike with a standard (threaded) 1″ steerer. You can either braze it into the steerer tube. (The steerer is usually not painted, so there’s no repaint needed.) Or you can glue it in with aircraft-grade epoxy. The surface area is large enough – make sure that both surfaces are clean to get a perfect bond. As always with frame modifications, consult with a qualified framebuilder."

It'd be interesting to see just how many of these stems get sold.

Cheers

I guess I am still trying to wrap my head around this great and marvelous invention. It seems to me it is a threaded to threadless stem convertor.

https://www.amazon.com/Profile-Design-Threadless-Size-Converter/dp/B0028N14GQ/ref=asc_df_B0028N14GQ/?tag=&linkCode=df0&hvadid=312065280674&hvpos=&hvnetw=g&hvrand=8394300032214473973&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9017849&hvtargid=pla-499887744437&ref=&adgrpid=62425943472&th=1

The link is for a 1" threaded fork to allow you to use a 1.125" threadless stem. But I have also seen ones that were 1" quill to 1" threadless stem. Back when 1" threadless stems existed. I can sort of understand the reason for the quill to threadless adapter. Maybe some people want to take their bars on and off lots. Easier with a threadless stem.

But with this Rene Herse thing, they are making the threaded steerer to permanently forever and ever only take the now smaller clamp threadless stem they are selling. Capturing the market with a product you cannot ever get rid of because you brazed in a new tube inside your fork. Permanent.

Why? I'm sure if you looked long enough you could find an equally pretty threadless stem as the Rene Herse one on the website. Or just have a stem custom made for you. Still cheaper and easier than gong with this thing. I just don't see any advantages or benefits to this wonder.

Tom Ritchey did the same thing on his forks in the middle 1980s.
