Saddle bag (size Small) https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
LED front and back lights are by BK-NY.

In my small saddle bag I can fit, 2 tire levers, patches, 2 co2 cart, co2 inflator, wallet, lock, and a spare tube rolled up in a sock. Only thing I couldnt fit was the multitool, with the larger saddle bag then most likely but I want to stay as slim as possible.
Controltech water bottle matches the bike perfect.. going for a stealth look.
I also put a new water bottle cage from Specialized, Rib Cage II in matte black.

Thats about it for now, pretty happy with everything. may eventually upgrade the pedals.
