Hi, I bought my first bike (and this is my first post so go easy on me). My other one was a walmart type one and was free, so its an upgrade at $1000.

It is the Giant Fastroad TSR 2 (https://www.giant-bicycles.com/en-ca...2/20463/80568/). I wanted to get the fastest bike I could get at my store that would go on gravel. The cyclocross was $1500 which was way too expensive.

I am commuting 106km (on some weekends) at perhaps 20-30km/h the whole way, some of it on gravel. I changed the 25 tires to thick 32mm ones. I plan to carry a change of clothes, 2 books, and some food. Any aerodynamic bag suggestions (backpacks or mounted)?

(Also, is there a lock that I can get such that I can fit a water bottle holder?)
