Don't the really tesco's do cheap chains ... ? (I'm sure I once saw one but didn't pay much attention to it). Or what about Decathlon? how cheap is their basic chain?
They do yes and TBH they are pretty OK. They do however tend to be either 3 or 5/7 speed chains only.
A large number of kids bikes don't have more than 7 gears on them at the back....
Asda do chains at £4 or so with a joining link. 1/8 for hub gears, and 7 speed. Got one on the SS - perfectly OK.
Is that in store or on line?
In store.
Cheers. I don't need one yet but my road bike is a 14 gear so a spare chain or two wont come amiss. I have an incredibly tight year coming up financially so when I see a bargain I can afford I will try and get it for my spares box.
