TRIWONDER Bike Stem Riser Handlebar Extender Bicycle Fork Stem for MTB BMX Mountain Bike Aluminium Alloy Head Up Adapter

Arrived as advertised...

Works perfect and solved my handlebar situation where it was too low. Easy to install.

Made a great difference in riding comfortably and easy to install. I have a Fuji Absolute one.3, and will probably fit most bikes.

Application: Installed on Specialized Women's Rockhopper converted to eBike.Height: 138mmInstallation: Because of the length of the existing cables, some or all, of the cables (F/R brakes, derailleur(s)) may have to be disconnected to allow enough "reach" to install the stem extension. I tried a 180mm, and I would have needed to make all new cables to allow it to work properly. I needed a 140mm, which seems to be an uncommon extension, and this was the only item listed as Amazon that was close to 140mm. The fit at the socket seems a little tight, and the "filler/spacer rings" didn't exactly work out with the clamping area of the handlebar stem. But it was workable without too much trouble - And is much easier, and less expensive, than a handlebar change-out, which I tried but didn't work out because of the straight length available on the replacement handlebars.Why ?: My wife was having hand and wrist pain with the standard handlebars. Increasing the handlebar height shifts weight off of the hands and wrists - and more weight on the seat. This is not quite a "cruiser" configuration, but not nearly as aggressive (forward) as a trail/mountain bike, probably similar to a hybrid configuration.How'd It Work ?: Based on the first test rides, it is a noticeable reduction on the pressure on the wrists and hands - so for the intended purpose, I'd call it a 100% success for a very small price. My wife is very pleased with the result.Caveats: (1) This shifts the CG of the rider/bike rearward slightly. This does not appear to be a problem for casual road, or non-technical trails. It might be for more technical trails and aggressive riding - more forward CG promotes stability, rearward is less stable. Since this is an eBike with a rear battery, it is more noticeable. (2) The more upright riding position is less efficient because of wind resistance and body/bike geometry pedaling.None of this is to reflect upon the product itself negatively, it is the trade-off of shifting weight rearward and off of the hands wrists.

Works great, Looks fine. Bolts are ok just tighten incrementally between both bolts.

Made my handle bar about 3" taller. The included screw fit perfectly. You'll need Allen head wrenches. Be patient with the cables and don't tug on them.

Lighter weight than other brands. I shopped around for the lightest example I could find in this length. No one wants to add unnecessary weight to their ride. This did the trick, and it’s staying on my bike.Lots of adjustments for height. Great clamping ability. Black finish appears powder coated so it’s tough and durable. Very happy with the product.

Fits and does the job.
