### ⭐⭐⭐⭐⭐ My long stuff
*by M***. on 21 July 2025*

Got the bike out the shed to try cycling to 2 miles to work, being 6'3" and mostly all leg, when my saddle was set correctly, my handle bar position became to low, I cycled everywhere looking like I was going downhill on the Tour De France.....this little gizmo, saved the day, raised my handle bars up enough so I could ride in a more comfortable upright position, easy to fit yourself, just need some Allen keys...order the spacers aswell incase you need them, then return them if you don't. I didnt , so had to wait another day for them to come. Feels well made and sturdy..
