However with the UCI weight limit many riders use an SRM as it adds weight, so if the Vectors are lighter then it may mean adding more lead to the BB.
Non structural weight's been banned, they use cheep cassetts, chains etc. I think the SRM usage is purly down them being the best tool for the job rather than heavy.
Wonder what the take up of the Vectors will be like amongst the pro's
The question they (won't) ask is "am I sponsored by Garmin?" If yes, get given Vecros, if no, continue using your sponsors products.
