Having a little trouble finding an insurer who will cover my mtb for theft whilst at races (and they want 400 quid to cover it at other times) so I figure a decent chain like an Almax would be a better bet in the long run than paying out a fortune for insurance. Are they really as good as they say? I'd hope they would be for the amount of money they cost. Which lock though? Squire SS65CS or the CISA one?
