I BMX and recently my bars have been slipping a lotIve tightened the stem but they still slipHow can I make it stop without buying a new stem or new bars?
you could try making a shim by cutting a strip of aluminium soft drink can with tin snipswrap it round the bars and retighten the stem over topmy singlespeed does the same thing sometimes but i just put up with itin my case there were originally gradations around the outside of the bars to provide traction and these have worn downideally i should get new parts but i like the old look.
