Stem With 0 Reach
 
Hello everyone,

I'm wondering where I can find, or if anyone even makes, stems with ZERO reach. I assume that it would be easier to make a threaded one, if not impossible to make a threadless one. A stem with zero reach would have the bar clamp directly on top of the steerer tube, making the rotational axis the same as the center of the handlebars.

I don't know if anyone makes these, but I'm pretty sure that I've seen them around. I suppose that if worst comes to worst it would be possible for me to make my own - take a normal quill, chop off the elbow and weld the two arms together as straight as possible, haha.

Why would you want that? What kind of bike are you talking about? I know mtb's have hb's with a rise that might negate some of the reach. Don't think I've ever seen any that big though!:D

If you're talking roadbikes, anyone would say you have the wrong size bike unless the rider needs certain accommodations for certain reasons.:)

The bar would be hovering over the top of the stem. How could that be?

The closest you'll find would be BMX stems.

Something like this?

Looks like you could move that around for 0 reach.

Wouldn't this make steering super twitchy?

RANS makes them. They use them on many of their bikes, such as the Fusion.

I have a 2006 Fusion. The fork is a 1" threaded, there is a "threadless"-type adapter that sticks 3" out the top that is 1-1/8" diameter, and then the "stem" is a 5" tall tube with the handlebar clamp integral on top of it. The handlebar diameter is 7/8", I don't remember if there's any shims in mine or not.

You probably didn't want a stem that added 5" onto the height, but it may be possible to cut it shorter.

RANS has a website just for the crank-forward bikes, including a forum-
http://pub23.bravenet.com/forum/1970022224
You should ask this question (of using a RANS zero-reach stem on a regular bicycle) on there; the parts in use may have changed since I bought mine.

Also you could ask in the Recumbent forum here, or on Bentrider online. There may be other recumbent companies that currently use zero-reach stems but RANS is the only one I know of right off.

Where are the wedges on these stems??? Or are they pinch bolt type?

The one on the right looks like something home made!!!

The tube at the bottom is split (one on each side) so the expander (the thing just visible at the bottom) forces the two parts out against the steerer tube.

Here's one.

Bingo! We have a winner, but with an asterisk.

Ah yes! This is exactly what I was talking about, although you are right to mention that an extra 5" rise isn't quite ideal, haha.

Sorry it took my so long to reply to this--I don't really frequent the forums that often so I didn't realize anyone had replied until I got an automatic email this morning.

As to the other posts - those quills are very close and BMX stems are almost there too, but yeah, the RANS is exactly what I'm talking about with there being absolutely no reach at all.

This would definitely make steering quite difficult and is not meant to accommodate an oversized frame, but I would like to buy one merely for experimental purposes. I will take up the suggestion and head over to a recumbent forum.

This information is quite helpful. Thanks guys, and let me know if you find anything else!
