New forum, new avatar. Hello matey peeps.
In LIDL this morning for my weekly veggies shop. Had a look at the bike stuff, then in amongst the DIY stuff they have a chrome vanadium hex (allen) key set for 4 quid. Sizes range from 1.5mm to 10mm, the 10mm one is about eight inches long. It comes with a gert big handle for extra leverage. Good value for bike fettling I would say.
