Agteros Posted July 28, 2012 Posted July 28, 2012 Some guys like wigggens' helmet has its vents solid? is that a new model orwhat?They cover it up. Less wind resistance, so they save 7watts(hope I recall correctly from TdF) or something
greenlight Posted July 28, 2012 Posted July 28, 2012 (edited) Well a good TT helmet knocks off 16min over 180km might be more, even 20min easy for a pro cyclist the old giro advantage 2 helmet knocks off 10min over 180km Garneau is prob. the best 15% more aero than the giro, I have the Giro advantage 2 carbon which is not real carbon only called carbon because it is black and is very very heavy the TT helmets actually keeps my head cooler than a normal helmet! because the air swirls inside and on the back area Edited July 28, 2012 by greenlight
