Made the switch back in 1999. Got rid of an Orange clockwork, ‘dale tandem. Made sense at the time as i started to compete and enjoy training with our local Tri club. Training was easier, no need to drive to the start of any rides, easier bike maintenance, attained a greater fitness by far than i had ever done on the MTB.
Lasted about 6 years before I just became bored with it all and didnt ride for a few years.
Last year bought an Orange R8 pro and a Saracen Tufftrax for my lad and regained my love for the dirt.. Have the road bikes hanging up collecting dust in the garage,… I plan to get back to the road, but not at the expense of the MTBing. Its probably because that i throw myself at anything i do with such a blinkered focus, to the detriment of everything else, and find myself feeling stale and wanting something different. Gotta mix it up a bit to really appreciate both IME.
