Sirrus Sport rider review

May 2024 · Matthew DePasquale

My wife found this bike outside the trash bins in our apts. The owner must have upgraded considering it's a 2012, with that being said the condition

Highs
  • Sleek and loaded with best gear

Lows
  • The flat bar means bending pretty far over
