Wake MTB Stem 31.8 90mm 110mm 0-60 Degree Adjustable Bike Stem Mountain Bike Stem Short Handlebar Stem for Bicycle, Road Bike, MTB, BMX, Cycling (Aluminum Alloy, Lightweight, Black)

I'm very satisfied with my purchase of the Wake MTB varaiable stem. For the price, less that $20 I was a little worried about the quality. However, I'm happy to report these feel just as well built as any bigger name brand stem. The variable geometry will come in very handy on my hybrid road conversion project where things can get wonky.My biggest concern when purchasing was whether one would ever be able to get the pivot bolt tight enough to completely keep the stem from moving. Like when you hit a pothole or something. Nicely, this turned out to be a non-issue. The inner portion of the linkage is what's known as a rosette surface. Basically, a bunch of interlocking "V's". The result is that once it's tightened down it doesn't budge.***My Rating Criteria***5 Stars: Works exactly as advertised, fit/finish are what you'd expect when purchasing this type of product AND it is a good value4 Stars: Works exactly as advertised, fit/finish are what you'd expect when purchasing this type of product, might have a minor flaw3 Stars: Generally works but I'd change a few things2 Stars: Barely works but can be made useful if you try1 Star: Useless, does not perform it's intended function whatsoever and is generally a waste of money

First, as stated in my review I am a tall person. I recently purchased a new bicycle to replace a bicycle that was about 10 years old. My size falls right just below needing a XXL bicycle so the XL bicycle will have the seat extended significantly. This places the handlebars low and was making me put a lot of weight on my hands. After riding a few miles my hands would go numb. I did discover that the bicycle store had installed the bicycle stem for aggressive riding (i.e., pointed down) so I reversed the bicycle stem to point upward. This made a difference. I started looking for a higher bicycle stem and most were fixed adjustment. Then I found this one and when I seen that it had positive teeth engagement (versus friction only) I decided to try it. I first tried a 30 degree adjustment but finally ended at the 60 degree adjustment. I like this much better than an extension as it does not increase the moment and stresses in the bicycle stem. I can also now ride 20 miles without my hands going numb.

Like a custom fitted bike. My aching back will ache no more. I love it. Had the bike shop install it, took 15 minutes. Highly recommended. Trek Marlin 5, 21.5 frame.

I recommend this item to bring the handlebar up and back to let me sit up straighter. Make sure to carefully measure both the stem and the handle bar diameters. This unit is 1-1/8 x 1-1/8 (stem x handlebar). I needed a 1-1/8 x 1. I should have purchased the split bushings for the handlebar. Fortunately I have a lathe and I fabricated my own. One more warning: The unit is slightly shorter than the existing goose neck and consequently The cap that tightens the stem bearings no longer worked. Again, using my lathe I fabricated a spacer from a water pipe. These spacers can also be purchased separately.

Worked better than expected and was easy to install, seems of very good quality. I installed on my dual sport/hybrid bike by swapping partially and installing it on handlebars loosely first, disconnected existing one partially, slid new one into place and finally swapped it onto the stem. in one move, then tightened it fully and removed old one. This way I could do it myself and nothing was hanging down, didn't have to juggle or risk losing parts, etc. A true swap maneuver!Just bring your bike tool with you to tighten up after your first test ride, took a bit of readjusting as I did not want to over tighten it up and then it was very solid. I put mine at 40degs and I probably did not need the 110mm version, but all works fine and bike is much more comfortable overall. Rode bike a few times and is holding solid, but will check it periodically. Got it perfectly centered without issue.Is solid black color, so matched the one I replaced in color. Same as handlebars.

I had to order this very quickly for a weekend when I realized my new handlebars were thicker than my older ones. As such, I had to make a hasty decision to get in the shipping window. So far, I haven't regretted it. I had previously owned an adjustable stem (which you would think would be a no-brainer as opposed to misjudging and having to return and re-order until getting the correct size). However, that stem didn't stay clamped and I frequently had to stop and retighten on my ride -- a real bummer. This one stays tight, and that's about the only requirement I had. Love it!

worked great, has so much adjustablity that it enables you to get the grips right where you need them. Well made, fits the stem adapter I bought for my old mountain bike very nicely. All screws and fittings were finished, the workmanship was great and usable right out of the box, not needing additional work. Installed quickly and easily. Priced reasonably for a high quality piece.

I guess this is a three item review as these are the three items I chose to update my Trek Navigator 100 with a new wider handlebar. My son says wider bars save life’s and after hitting some debris and loosing control and doing a face plant giving my self a concussion I tend to agree. All three items came with in days of ordering and they all worked well together and as anticipated. The switch over actually only took an hour including test ride and adjustments.The three items were BW 31.8mm MTB Handlebar - 760mm Length x 31.8mm Diameter x 5mm Rise – Blue Sold by: BC_Outdoors, UPANBIKE Road Mountain Bike Bicycle Stem Riser Adapter 1 1/8" φ22.2mm 25.4mm150mm Sold by: Abuyamoy (this was needed to adapt from my threaded front fork to a threadless stem mount), Wake MTB Stem 31.8 110mm 0-60 Degree Adjustable Bike Stem Mountain Bike Stem Short Handlebar Stem for Most Bicycle, Road Bike, MTB, BMX, Fixie Gear, Cycling (Aluminum Alloy, Lightweight, Black) Sold by: HYTE Direct
