Right then, i’ve got a 2012 mega in a medium size and I’ve been offered a 2014 Mega Am, also in a medium. The 2012 mega has a 22.6″ top tube whilst the 2014 is longer at 23.4″ , all the other measurements are near enough the same (the reach is 415 for 2012 , 418 for 2014,wheelbase is 11mm longer on the 2014). Anyone either tried both or have any idea if the 2014 will feel a little longer? (im finding the 2012 a smidge short)
