I’m so happy I made the investment
I bought this bike in December of 2025 and I’m so happy I did. It rides smooth and it changes gear so nicely. Also, it’s so much lighter than my old bike. Super happy
Light, Crisp Handling
A very comfortable ride! The hydraulic disc brakes are good against steep descents and the 50T rear granny gear eases climbing. Sweet bike!
