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 45 mm x 31.8 mm stem

Chromag are the only maker of quality after market stems that offer a stem that is near to the magic 44 mm (matching trail on a 29” fork) for that balanced, neutral steering one wishes to have on a perfectly balanced bike.
Whilst the Riza is overbuilt for my purposes it is nice to know that it can take the kind of slams that Ramage winners hand out to their bikes when it doesn’t all go to plan.

The machine marks give it a harmonious aesthetic and the use of M6 bolts on the steerer and the face plate mean that only one tool is required to fettle this premium component. Chromag don’t offer an upgrade kit and probably have strong feelings about steel bolts but I feel that the rainbow titanium bolts I have used give it a certain pop.

The main reason to run it is the neutral steering and no-one else makes anything close to a 44 mm stem in the 31.8 mm standard.

Great customer service with prompt answers to questions and fairly swift dispatch into the post.

I have them on all three bikes now as they hit that perfect length between 40 mm (too short) and 50 mm (too long).

Thanks Chromag for filling this gap in the market with a littel chunk of awesomeness.

Great quality, just beware of hidden import fees on delivery. Ended up paying £95 delivery.

Riza stem

This is my third Riza stem. Best stems out there. Strong, reasonable weight, dead sexy.
38mm perfect for mtb, 45mm perfect for my custom gravel bike.

Cutlass Bars & Riza stem

I recently bought a Chromag Riza stem and Cutlass Carbon Bars. The paring looks amazing on the bike and they are as advertised for strength, flexibility and durability. Awesome combo!

Beautiful and confidence inspiring

I don't know any other stem where I can run the bars so close to the sterer tube, helps so much with barspins and corners

Not my first Chromag stem, not my last

I put a Chromag stem, bar and saddle on every bike I own and have been for around 20 years. The Riza is my first choice, as it is build sturdy enough to take the abuse bc bikes receive, and is locally CNC’d. It doesn’t hurt that it looks sharp too.

LOCKED IN

As locked in as you can feel on a bike with this stem. I went from a standard width stem to the Riza and crazy how much of a difference in stability and control I noticed. Cheers.

From Canada, With Love

Made in Canada, and it shows. The quality and finish is top spec. Everything just oozes of quality. The stem's clamp area is beefy, so you know your bars are secured, and have strong hold.

Sweet stem. Feels twice as solid on my bike as it looks in the photo. If you’re wondering whether you should get one, the answer is ‘yes’.

I am a chromag athlete, and having got my hands on this snazzy number when they came out i can't get over how good it looks and performs! i have one on the slope bike and another on the pedal rig and its honestly an amazing stem to run, not only is it dead sexy but stiff too! it's a dream build item for me! 10/10
