TRIWONDER Bike Stem Riser Handlebar Extender Fork Stem Adapter for MTB, BMX, Mountain Bikes, Aluminum Alloy Head Up Riser

Easy installation. Works great.

Simple to install, (watch a install HB Riser YouTube video). The extra height noticeably helps w neck, shoulders and wrist comfort. Looks nice on my black bike.

Big tip: If you think your cables are too short (mine were not) slip your handlbars over it BEFORE putting it on. Saves about 2 inches of initial raising. It was a very easy install. The weight of it was more than I thought, as some reviews said otherwise. Pretty solid. I had no trouble tightening it, or over tightening it. It was a very, very tight fit and I had to hammer it on down with a rubber mallet. Caution: If it is tight on yours, be sure it is lined up before slamming it down. It is very hard to twist off. I did not twist it off to realign it, just used a piece of wood and hammer. It does not matter anyway if this is out of alignment, as that only affects the look. (Of course you align the handlebars!) You can use all the spacers, and tightening your handlbars with a little space is below the top is fine. My bars had good bolts and grabbed. Like I said, don't worry about over-tightening and stripping it. Just do it hand tight, and a small amount more. If it does strip, no big deal. You can buy bolts and nuts that would go through just fine at home depot. But it was a tight fit on mine and would probably hold without even tightening! But I would not recommend this! Anyway, it is a solid deal. And get this: Once this is in place, if you want to go even higher, NOW you can buy the adjustable ones and install easily over this one....I might do that in the future.

Application: Installed on Specialized Women's Rockhopper converted to eBike. Height: 138mm Installation: 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.

Good use to increase hight of the steering

Its easy to install and makes riding so much more comfortable. I wish I would of bought one a year ago. No more back ache from leaning forward so far

These work great, put it on 2 mountain bikes to raise the handlebars to a comforable height.

This worked perfect on my bike allowing me to raise the handle bar several more inches. It was easy to install and simply works.

Conforme à la description

Perfect for raising the handle bar on my mountain bike. I am a heavier rider, and found the handlebars too low. This has raised them to a comfortable level and I feel like I have a totally new bike. 100% improvement. No more sore back or sore hands... Riding in comfort. Highly recomment. Very good wulaity product.

This Stem Riser is excellent, build quality is first rate and the whole thing looks very neat and tidy when fitted. Very strong and robust looking, feels very safe and secure when fitted. Fitting is very simple and takes about 10 minutes to complete. I bought this to give me a better riding position, giving me a straighter back, reducing strain and making my cycling much more comfortable/ enjoyable. Works great back is fine and my seating position is much improved.

Cumple con su objetivo, los materiales son de buena calidad, se instala con facilidad, quizá el único inconveniente es el diámetro de los tornillos serían mejor más gruesos.

Buon materiale facile montaggio la schiena non mi fa più male dopo aver alzato il manubrio
