Road.cc Saddle bags are a useful accessory but can often ruin the look of a nice bike; a baggy material with velcro straps wrapped around multiple surfaces. The Lezyne Pod Caddy does away with straps and bagginess creating a saddle rail mounted hard shell case. In-line with what I've come to expect from Lezyne it's a stylish and well made bag that will not look out of place on a high value bike. I was looking forward to testing it on my Giant TCR as with its aero post fitting a standard saddle bag proved cumbersome and I also wanted something I could easily remove when racing. Unfortunately the Pod didn't fit either: the rail mounting interfered with the seat-post clamp.
