Carrying spare tub

I'd be interested to know what tubs you're carrying and how you can get them so small if you wouldn't mind sharing?

I ride on tubs all the time and, whilst I do use sealant, I carry a spare just in case.  Folded up and held together with some strong elastic bands, I just slip it into my back pocket.  I used to mess about strapping it under my saddle but there always seems to be room in my pockets, even with banana, phone, etc.

Agreed that a saddle bag may be the best option. On the longest rides I fit two in there plus sealant just in case. Get a bit paranoid about puncturing tubs but thankfully it's a rare occurance.

Do you need to carry a spare tub? I used to carry the inflate and fix canisters that work a bit like Stans sealant, not that I ever had to use them. Should fix most punctures. Planet x had some for about £4 so cheaper than a spare tub too and would fit in a jersey pocket.

I have a saddle bag for underneath my seat that I use for all my tools and a spare innertube.  It keeps it all secure and in one place.

I used to fold mine up and strap it to my tool bottle using double sided velcro

Worked perfectly, even fitted in the bottle cage on its own
