Carbon water bottle cages

[Trekhawk]

With the sideloader, do you have to pull the bottle out of the side that's open (in other words would I have to train myself to use both hands to reach for a bottle) - or can you pull the bottle out of the cage from either direction?

Yep as Cali said you have to pull them out from the open side. Trust me you can do it - if I can do it anyone can.
