So my crank arms are a bit loose, i've tried almost everything except loctite, that everyone suggests i do so.
I'm looking for suggestions on a crankset and a BB, for last resorts, as im afraid i rode the bike even with the loose arms.
If you rode on them loose then the crank arms (assuming they are aluminum) are mishapen and will no longer stay tight.
New crank. We have no idea what you own so its hard to recommend you something, but look into something cheap like origin8. Decent crank for the money.
