A dent in an aluminum frame would be deal breaker for meEspecially if it is a very high end frameIt was probably made as light as possible to begin with and even a small dent could grow into a crack in timeI too weigh about 240lbs and generally stay away from very high end equipment unless it was designed with my weight in mindMost high end frames and components were designed around a more typical rider around 170 to 180 lbsI do ride aluminum frames but I am wary of really light weight ones.
aluminium chloride is a typical ionic bond because the one atom of aluminium is donating its three electron to the three atom of ChlorineSo it has no covalent characteristicsAll its characteristics are ionic that is it can be used as an electrolyte, it has high melting and boiling point and e.t.c.
Thats rightHigh zoot frames tend to be heavily affected by dentsPass on the deal.
