Wanted to have a bottle cage on my 1950's Hercules and this looked ideal as it shouldn't mark the original paintwork .
Fitted easily and tool free , just make sure you pull really hard to gt the straps as tight as poss otherwise it will move around .
Straps are too small to fit round the bar on my bike - universal implies it fits most bikes?
I'm sorry to read that the straps are too short for the thickness of the down-tube on your bike.
If you could, would you mind sending me a photo of the frame as I wish to forward this on to the person at b'Twin who manages this item.
In the meantime, please return it to your local store for an exchange or a refund.
