Topeak

This product just worked... Fitted essentials plus a few small extra'sI have managed to fit:2×co2 cartridges(16g)Xlab tyre mate combustion pump2×plastic tyre levers1×700×35c hybrid innertube1×valve core tool2×aluminium valve caps(presta)2×plastic valve caps(presta)1×presta to shader valve apater(brass)Keys at a pinch.. Advise using a standard fit bottle cage.. I use a Cannondale side loading cage and have to velcro strap and carabiner clip it on the the cage so it can't creep or slip..

Well thought out storage for various items on the bike. I have a puncture repair kit,multi tool, co2 and a spare tube in mine. Very secure in the bottle cage. Only downside is it’s quite hard to keep clean due to the fabric.

well made and good product

Great bag suitable for the essentials and avoid an ugly saddle bag and much quicker to switch between bikes.

Another well made product from topeak, does exactly what it says. Would definitely bye again

Great little bag with plenty of space for multiple items of your choice, but won't stay in a standard bottle cage without popping out all the time, so I'll be sending it back. Updated!

does the job great

A very useful holder. Well made, but a tad expensive
