Rollers are something to keep simple.
I like my Sportcrafters Overdrive Pro rollers.
I have the inertia drum as well.
Soooo.........For basic form and base miles I just roll with the regular drums and the inertia drum.
If I want to do intervals I swap in the resistance drum...
and it kicks my ass. It's great.
Nothing like getting out on the road and having the super cardio.
Simple. I paid $425.00 on sale.
Best cycling money I've ever spent.
