Ah, What about Truvativ? I took my cranks off to better clean them (and, to be honest, because I could - I've never had this type before. So simple.)
And that's my problem! I took them off by undoing the inner hex bolt on the non - drive side. But when I put them back on I tightened both inner and outer bolts - don't ask me why. I assume from Zinn I shouldn't have done that. What is the correct procedure? Tighten the inner bolt, then leave or tighten the outer? Only owned the bike 3 weeks and ideally I'd like it to last....
