Topeak Modula Bottle Cage

The Modula bottle cage weighs around 75g is unique because of the ability to adjust the size of the cage to fit smaller bottles. Anything bigger than a one litre water bottle will not be able to fit in, even 1lts Nalgene bottle.
This bottle cage is not ideal for off-road action, there are many times the water bottle just felt off the bike. Ideal for road touring when you buy your drink from a road vendor or 7-eleven.
