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.

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Really good!!!!
*by P***Y on July 19, 2025*

Really great product. I ordered one but can not install due to wrong size I ordered. Quality seems top notch and finish quality is amazing. Had to return. Will order different size.

### ⭐⭐⭐⭐⭐ 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.
