I bought this saddle bag to go on my new bike.it's a small size and ideal for a mobile or a few small tools and a couple energy bars.
It could do with another strap that wraps around the seat post to stop it from moving and that's what I have done is stitched a velcro strap to the bad and now it does not move.
I would recommend you buy a bigger one and one that sits more securely.
Looks nice, Small and compact
Don't sit right and moves a lot.
For the price the saddle bag is a must for every cyclist out there.
Plenty of room to store a spare inner tube and tools.
Light well made and really cheap
Can't find anthing negative
