### ⭐⭐⭐⭐⭐ Review
*by A***. on 23 December 2022*

I have a racing bike, although I don't use it as such. It's just another bike to me to take out for a little cruise around the neighborhood. The rock hard racing seat on it was as uncomfortable as can be and I didn't enjoy riding for that reason. I needed a post that would fit the bike and also the new seat I purchased with LEDs on it for nighttime riding. This Topbuti bike seat post worked out perfectly! It fits perfectly into the bike frame and the seat fit very nice and snug on it. Great purchase!!! Thank you!!!
