XLAB Hydration System (Transition Mount 2 Pre-installed)

Went on a 65 mile ride yesterday and used the seat bottle attachment for the first time. Worked perfect as I can get way with 2 bottles on a 40-60 mile ride when I really manage the liquids with electrolytes on a 2 bottle ride. The extra water bottle seat attachment allowed me to take in fluids every 3 minutes and maintain body hydration and electrolytes from the start of the ride to the finish.

Water bottle mount rides too high and with a bottle in it is in the way of leg coming over on dismount unless I really bring my leg high, will keep the bicycle rack mount on for race season to make race racking easier. Wish I could drop the bottle mount lower.

Needed more water on rides. This worked perfectly
