I purchased a Rock N Roll V1 in 2013 and used the heck out of it being that we have snow 1/2 the year.
I noticed a couple of cracks in the frame and Kinetic sent me out a new frame for free this past week being that they have a lifetime warranty on their trainers. I think tis is excellent customer service and i am a lifelong fan as a result.
The Vs is smaller - the wings don't take up as much space and they have refined the way the trainer rocks n rolls.
Feels great and I am a happy camper again being that we are still getting friggin snow here but today with he help of my trainer and CVT 2015 I am riding the tour of Battenkill in my basement.
Thanks Kinetic!
