I don’t always ride with a saddle bag. If I have panniers, I prefer to use them to carry stuff. Also, when I’m commuting, I rarely use one because I don’t want to leave the bag on the bike if I lock the bike up somewhere and someone help themselves to the contents. So, I mainly use the saddle bag for longer rides where the aim of the ride is just to ride. I guess a training ride or just a joy ride.
What you put in your saddle bag is up to you. But here are some suggestions and ideas as to what will fit in a saddle bag.
I have two saddle bags. A regular sized on and a large expandable one. The photos have a 30cm ruler for size comparison.
What I put in my regular saddle bag:
- spare tube
- tyre levers
- thin lock
Extras that fit in the large saddle bag:
- sports towel
