Hello all
I got a Sirrus 4.0 back in February. I've been tweaking the fit little by little as it felt cramped after I brought it home from the LBS. It's a large and I'm 60 years old 6'1". I swapped the out the stock 170 crank for a 172.5 and a 120 stem from the stock 80. It feels much better now. My other bikes are a Tarmac SL6 and a Bianchi BOSS. I am trying to make the Sirrus a bridge between the two. It's unlikely it'll be as fun as the Bianchi. My carbon wheels should be delivered this week. Can't wait!
