I like it as a solution, until I saw the price!
I’d be more interested in it if they made multiple cable versions; so the same design but able to hold 1, 2 or 3 cables.
You could then use one of these to secure your front mech, rear mech and rear brake hose in one clamp.
Another thing – he/they moan about the classic zip tie scratching a bike frame, but seeing as this leaves the zip tie exposed against the frame too, it doesn’t really solve that problem.
They describe it as a durable rubber, so if they had added longer sections to the end that could be trimmed you could wrap that round the tube & cut it to length before securing the zip tie. This would act as a cushion between the frame and the tie, as well as improving the grip to the frame and stopping them shifting about.
