@MI-XC I think you described the crux of the argument. I really can see the benefits and detriments of both using and not using a mountain bike.
My instinct is telling me to use a road bike for SSB1, SSB2, and maybe Power, then switch to the mountain bike for speciality. Or maybe switching to a mountain bike during the last few weeks of the Power plan.
In addition to the mental benefits you describe I think as you get closer to the A race/race season it’s good to start strengthening all those little stabilizer muscles that get used when putting down power on a bike with suspension. While in the sweet spot phase it might be more beneficial to do the workouts on a road bike as you are maximizing the amount of power you will be able to do during a particular workout and thus your adaptation is being maximized. If you can do VO2 max intervals at 350 on a road bike rather than 333 on a mountain bike the adaptation will be greater due to the higher overall number on the road bike, correct??
I’m planning on using a coil shock for the season and even with a lockout there is significant pedal bob that zaps power. I’ve noticed that if I am smooth in my transition from one power zone to the next then the amount of watts that are zapped is significantly reduced. Basically don’t be a spaz and try to go from 150 watts to 500 in 2 seconds and take the time to transition from 150 to 500 over three seconds makes a big difference in how the bike handles, reacts and accelerates to changes in power. An airshock handles quick changes in power output much better but comes along with the disadvantages of an air shock. I would think a month or so on the coil bike in doors would be beneficial as I transition to outside rides/workouts. I mean at some point it’s not going to come down to raw power output and you are going to enter the season with whatever ftp your training has given you and the gains are going to come from bike handling skills, cornering, and stage strategy.
Ok. Way off topic. It’s soo exciting to be a gravity athlete right now with so many options regarding training, equipment and riding along with the base of knowledge and putting it all together. Thanks for listening to this deep dive. In definitely interested to hear other’s anecdotal evidence on this topic.
