Review: Fantastic quality bike Riser - This bike riser was easy to install. It is strong and durable. Great value for the money. This bike riser raises handlebars just enough to minimize nerve damage to hands but not so much as to require re-doing brakes.
Review: Comfort and Quality at a great price - Put this on my Trek X-caliber 9 mountain bike, been riding a lot on dirt roads and rail pathways this spring so i have been riding in the saddle most of the time (not really what the bike is designed for), as a result my neck and lower back have been aching after the ride, so i figured i would give this inexpensive stem a try. The stem looks very well made and finished perfectly, no complaints here. Swapped out the stock bontrager stem (80mm long / 7 deg) and after 2 rides i am feeling much better, neck strain gone and lower back ache improved. It just puts the bars in a much better position for me, i might go back to the stock bontrager stem when i start doing single track but for now i am loving this stem and would recommend to anyone looking for a little more comfort on their cross country ride.

### ⭐⭐⭐⭐⭐ Fantastic quality bike Riser
*by J***R on August 9, 2024*

This bike riser was easy to install. It is strong and durable. Great value for the money. This bike riser raises handlebars just enough to minimize nerve damage to hands but not so much as to require re-doing brakes.

### ⭐⭐⭐⭐⭐ Comfort and Quality at a great price
*by M***L on March 21, 2021*

Put this on my Trek X-caliber 9 mountain bike, been riding a lot on dirt roads and rail pathways this spring so i have been riding in the saddle most of the time (not really what the bike is designed for), as a result my neck and lower back have been aching after the ride, so i figured i would give this inexpensive stem a try.

### ⭐⭐⭐⭐⭐ Fixed my Trek X-caliber 8!!!
*by Z***H on March 23, 2025*

Bought a frame size XL but really should have bought a L. I am 6'1 with a 31 inch inseam and on my XL Trek X Caliber 8 bike, the reach was a bit much putting way too much weight on my wrists and made for a uncomfortable ride. Asked Chat GPT how to fix it, and it recommended replacement of the stem. Found this, looked about what I needed, shorter and taller, put it on and WOW! Now I am more upright and comfortable and feel that the XL frame is PERFECT! If you end up buying a bike that may be a tad big, give this thing a shot, made a WORLD of difference. Install is very easy with basic hand tools.
