Where to, boss? ALDI, and step on it! Cheap Aldi Cycling Stuff

I joined the club last night, it fell off on the rough roads around here I think.

Thanks for the blu-tac tip. Has anyone used the cover off a usb stick or owt else similar for this?

The ones that Lezyne use on their lights might work. I think one of mine if dead so you can have the rubber cap. Will have a look tonight.
