Review on 🚴 XLAB Stealth Frame Bag: Boost your Aerodynamics with the Stealth Pocket 100 by Tyler Cooley

Size 100 is the same as size 200 with a few differences. Model 100 uses Velcro instead of studs, has an inner pocket instead of a shape enhancer. Without the shape enhancer, the bag becomes more flexible, but zippering becomes more difficult. The 200 version attaches easily due to the screw connection, but the 100 version sometimes requires two hands to operate as there is no screw connection. However, the underside is very grippy so it doesn't wobble or bounce in any direction. It is spacious enough to store multiple bills, keys, small bills, etc.
