Sometimes the most simplest of ideas are the best ones to solve minor problems.
In cycling sometimes you want to carry gear on your bike and not on your back but the problem is the bottle cage is sometimes in the wrong place, either too high or too low on the frame.
The photo below shows the bottle in the perfect place on my Travers Rudy 29er for reaching down and drabbing a drink while on the go.
But fit a frame bag like the Wildcat Ocelot frame bag http://www.wildcatgear.co.uk/shop/frame-bags/ocelot/
and you either have to use a tiny water bottle or carry your water in a backpack which some of use don’t like doing.
So, from a post on The Bear Bones Bike Packing web forum http://bearbonesbikepacking.co.uk/phpBB3/viewtopic.php?f=7&t=5288
I ordered one of these
From Mount Skidmore over in Australia for the princely sum of just £11.12 and that included postage halfway around the world in just 9 days. Their website is here http://mountskidmore.com.au/
And here’s the after picture showing the bottle now about 35mm lower in the frame meaning a 4″ deep bag to carry more gear and a larger bottle as well
