>>1190361You could ziptie something to your stem. pic related was for an old stove. lots of camera bags work well, or anything made to go on a belt. have a look in a second-hand store. won't fit bananas but you can put some chocolate bars or gels in it
ziptie a small basket on your rack, like one for washing pegs, or a bag on there or something
get another bottle cage and put stuff in a container/'storage tube' in it
get a saddlebag? it's nice having easier access though
