Everything you love about the RIZA (who says you can't love a stem?) but in direct mount!

We've used our knowledge of making stems for almost 20 years to create a new, highest level bar grabber.

There's no doubt the RIZA is our finest stem to date. CNC machined from premium 6061 billet aluminum, it features our new faded edge on the clamp face to help avoid hot spots and stress risers when your bar flexes under load.

*Note: While the RIZA is compatible with all modern dual crown forks, on a Fox40 or 49 you will be limited in how much the crown can be dropped as the stanchions will contact your handlebar. Fox has more offset in the crowns than other dual crown forks creating this limitation. Please reach out for advice on your specific situation.

Stem FAQ's

There are really only two bar diameter standards these days, 31.8mm and 35mm.

Make sure you find out which one your current bars are!

Almost all forks nowadays have a 1 1/8" steerer tube at the point where the stem attaches.

There are a few forks still around with a 1.5" steerer but it's quite unlikely you need to worry about this.

You can always measure your current stem/steerer if you want to be extra sure. (1 1/8" is about 28.5mm)

This is very tough for us to answer but somewhere in the vicinity of your fork offset is generally a good place to start.

Remember, a longer stem doesn't really make up for a bike that is too short for you (and vice versa). It affects other things as well, namely handling.

We refer to this as "stack", and it's 38mm on all of our stems. (Apart from the direct mount of course.)

As much as possible! Your steerer should only be about 3mm shy of the top of the stem. (Just enough for the lip of the top cap to clear)

Pro tip: the steerer goes entirely through the stem and sticks out the top by about 3mm. Then use a headset spacer on top. This is how we build our bikes here at Chromag HQ.

You can read the full user guide here, but making sure everything is clean is a great start.

Follow torque specs, and make sure the faceplate has an equal gap top and bottom.

Handlebar markings only get you so far, if you want to be super accurate, get out the tape measure!

If something is creaking it's almost always due to dirt and dust. Take everything apart and clean. This would also be a good time to inspect for damage.

If you have a crash and tweak your bar angle, for the love of god loosen your stem when setting them straight. It also goes without saying to give your bike a good look over after a crash, especially the front end.

It's never a bad idea to replace your stem bolts each year (you'd be surprised how corrosive sweat is). We sell replacement bolt kits at a very reasonable price.

Riza Stem

Super nice stem would recommend

Strong, and solid design.

I have been running this stem for a few months now. The design is very strong, and the bolts clamp very solidly onto both the bars and the crown which is awesome. I am much less worried about my stem or bars coming loose now compared to my old stem.

Holds the bars on the DH rig.

This stem does an excellent job of holding my bars onto the bike. Since installing it, my handlebars have remained [perfectly in place. It also looks steezy.
