I recently found out that Racktime makes little snap-on bracks that let me turn anything I can drill holes in into snap-on modules for my bike.
The Bike is a rental so it took some time to figure out how to add a rear rack so that I can take it off if I need to return it but I am incredibly happy with the results!
Nice! Any recommendations on waterproofing gear/shoes when riding serious rainfall?
Layers are your friend.
I can break down the individual items I keep in my bag if that would help.
