How to raise handlebars on Specialized Ruby?

Hi, I want to raise the handlebars on my Specialized Ruby. It has a + - on the round cap thingy on the post, and a hex hole in the middle.

Can someone tell me how to do this?

Thanks
Tabriz

Hi Tabriz,

Why don't you post this in the Bicycle Mechanics sub-forum? The regulars there will be more than happy to help you.

Unless the ruby has a system peculiar to specialised- Can't see a problem but before I reply and possibly put you on the wrong track--Perhap a pic of the stem and bars would help.

I believe the +- on the stem is to change the angle of the stem. It will change the height slightly but not a lot.

If you have spacers above the stem you can remove the stem and put them under it. Some say to leave at least one above the stem. If the steer tube is cut short and there are no spacers you could try one of those mickey-mouse adapters.
You might also be able to get a stem with a steeper angle to raise the bars. How much do you need to go up?

The stem is has an extra large hole so there is an angled shim inside. Rotate the shim and you'll see the stem angle change. It will change 0*, 2*, or 4*. If the 4* isn't enough you'll have to flip the stem and set the shim at 0* and start from there. I believe the stem is a +/- 12* so there will be a BIG change when flipping the stem. Thats the problem I had when I tried raising my stem. It went from -8* to +12*. Too much of a change. I ended up buying a 6* (non-Specialized) stem but that wasn't enough. Finally ended up with a 0* stem. The shim only fits certain Specialized brand stems.

Here's the info about the stem.

Thanks Ron--I thought I had read that some Specialised stems were different.

Just a query- but can you change the Specialised stem for a conventional one? Sounds by your experience it can be done- but just for future reference.

I have a flippable Truvativ stem. It was already in the 'rise' position off the floor. I needed more rise. Lots more. If a flip does the job for the o.p. great, if not, then he will have to go the route of the Mickey Mouse stem (height) extender, no need (or benefit) in going to a different brand of stem. That is the route I chose. My extender of choice was the one made by Delta. Does the job. Some say they are ugly, but, it really is an "eye of the beholder" kind of thing. YMMV.

Here are a couple of documents from Specialized about their stems and mounting them on carbon forks.

They do not recommend using a different brand stem (big surprise ) because of the hole where the stem extends forward on other brands. This advice is frequently ignored.
They also caution against placing spacers above the stem on the steerer because of the expander plug used to hold the stem in place on the steerer.

I Have found the BBB BHP 21 a fine way to deal with a too short steerer,
as long an it's metal.

A well thought out stem raiser from the NL company , once its installed
it is just as if you had slapped the mechanic's hand
when he reached for the Hacksaw.

internal quill , with keyed shims to use as many as you needed, on the top ,
and a wedge pulling bolt made for the purpose,
internally threaded thru the 6mm hex , to screw the 6mm
headset pre load adjustment bolt into.

I use mine on my Koga Miyata WTR trekking bike , a used find.
brought it up to also install a second handlebar bag mount stem,
beneath the regular one.

the internal stem raiser & extra spacers, made that possible.
