Rated 5 out of 5 by from alternative to new stem and handlebars like some other reviews i enjoy my bike except for the handlebar height. on my bike, the delta stem extender raised my handlebars a tad over 2 inches. this small difference made my riding comfort much better. itsaved a stem-o-rama test and new handlebar purchase. my elbows, wrists and back feel better and my bike has better handling characteristics (2009 rocky mountain metropolis). somehow the more upright position feels better taking off from stops as well. some configurations may need spacers to properly secure the stem extension. in my case, i had a stem cap light mount that need to be palced on another part of my bike but this didnt turn out to be a problem.

Rated 5 out of 5 by from Great Product Great Price High Quality, low cost way to raise handle bars 3". Installation was quick and simple. I installed the Delta Stem Riser on a Novara Safari Touring Bicycle and my arms and hands thanked me. For the Safari, I just removed the handle bar, installed the stem riser, and reinstalled the handle bar; no cable adjustments necessary. I did have to remove one spacer so I could properly tighten the stem screw. Do secure the front wheel to prevent movement. Makes installation so much easier. Yes, I would recommend this to anyone wanting to raise their handle bars.

Rated 5 out of 5 by from Good solution For most of us as we get older the riding position aboard a mountain bike needs to be a bit more upright in order to avoid neuropathy in the hands, cricked necks and low back discomfort. This stem riser straightens you up just enough to make things more comfortable without rendering the bike unuseable for off-road travel. It does not require installation of new cables. You get a lot for just a little bit of money. I installed these on both my wife's and my own mountain bikes just a couple of weeks ago and now we're spending more time riding. Imagine that! 5 stars all the way. Good idea, good design, quality product, simple to install and affordable. Works for me.

Rated 5 out of 5 by from Does Its Job I commute to work almost every day on a mountain bike and I always wished my handlebars were just a tad higher to take some pressure off of my wrists, arms and back and so I could sit a little more upright in the saddle. I was looking at changing out the stem but I saw this Delta stem raiser and figured I would give it a try. It was very easy to install and it does exactly what I hoped it would. Now my commute is much more comfortable! It looks a bit odd the first few times you look at your bike, but I will sacrifice looks for comfort.

Rated 5 out of 5 by from works,requres careful installation This stem riser really helps take pressure/weight off these old wrists. In reading reviews and info from REI I did not see mentioned the necessity (IMO) of using a torque wrench to safely install this riser. The riser is at a critical junction and could create a potentially dangerous situation. It really needs to be installed with a torque wrench after putting bike grease on the bolt threads.

Rated 5 out of 5 by from Back and shoulder pain disappears After riding my new touring bike for over a year averaging 100+ miles weekly, I began to develop pain between my shoulder blades with occasional numbness in my lower arms and hands. I wanted to raise my handlebars up to relieve pressure on my back/shoulders, but the threadless type stem didn't allow for any more height. I discovered the Delta riser at REIs website and then rode my bike out to Redmond, WA store, purchased and mounted it at the store. I set it up so the handlebar was level with my saddle. On my 16 mile ride back home, pain/pressure disappeared immediately. Highly recommend it.

Rated 5 out of 5 by from Back Saver on old Mountain Bicycle The stem extender was pivotal to the success of retrofitting my 1994 Park Pre Mountain Bicycle. While the raised stem makes aggressive twisty trail riding a little less nimble, it makes family leisure rides amazingly more comfortable. 3 inches goes a long way to improving back posture. Another user recommended really tightening the attachment bolts, which I did, and never had an issue with the riser coming loose. Only had to lengthen one brake cable to span the new distance. Great update.

Rated 5 out of 5 by from Bike Saver! This product worked great on my mountain bike(now commuter bike). I try to commute to work 3 times a week so extrat height on my handle bars made a big difference. At first, I thought the stem riser would make my bike look "silly." However, since it's all black I couldn't notice a difference. The only issue with this product was on the install. It should have been simple, however some reason I needed an extact spacer to ensure a solid fit. After I had a bike shop install the stem riser correctly I had no issues.

Will installation of this riser necessitate replacement of cables on my Charge Grater2 (XL)? If so, which? I'd like to have them on hand if/when I do this. Thanks!

Asked by: bmoss
The installation of a new riser on your Charge Grater 2 may or may not require the replacement of your brake cables. This will depend on the stock cable length which we can't determine without a physical inspection. Also, due to the hydraulic brake additional shop work and parts may be required. This can be evaluated by one of our professional bike technicians at your local REI.

Am I able to cut down all the excess stem and the still function properly? I understand I may need to get a shorter bolt from hardware store to accommodate the length difference when setting pressure on the bearings. 

Asked by: Kenny
​We do not have that information available. We encourage you to contact Delta directly.

Other stem risers seem to use rings.  The pics for this item do not show them.  Are they needed and, if so, are they included?

Asked by: Mhigg
This riser does not come with any additional rings as they are not needed to use this riser.
