cheap, but velcro shreds shorts

Tools do what they're supposed to, but the bag i bought last year I cannot use on one of my bikes, as my cycling shorts rub against the Velcro straps along the seatpost. I prefered the older models with an elastic band around the seatpost. 5 stars for the tools, 1 for the bag.

Good deal

Was looking for a little bag and bike tool then saw this which saved a few quid. Not had to try the tyre leavers yet but everything seems well made. Would recommmed this little set, yes.

Decent kit

Saddle bag doesn’t fit under my saddle as I have it quite low down and the rear reflector and light would be obscured. Currently sits under the cross bar and is quite secure. Just about holds a spare inner tube, the multi tool and tyre levers with a little space left over for some loose change and a couple of house keys.

Great Little Kit

The multitool was the real reason for buying this as the individual one was out of stock. Tyre levers and small but handy seatpost bag a bonus.

Question about multitool

Looks like a good product and considering buying it but could you please detail what the multitool includes? Not sure if it includes everything I need to repair problems on the go!

Saddle bag
