Have briefly seen some photos and reviews of some dual water bottle cages that mount on the seat post and comments range from `fantastic` to `bottles fall out`.
I`m thinking I may have enough steering tube to mount one up front just above the stem. The on-line dimensions look OK but would rather hear from someone thats already done it.
And I can`t believe no-one has tried this already. For lots of commuters and for bikes with a step thru design it could be pretty interesting.
