Ok, thx. I decided to take the 3" drums.
Now, does anybody recommend the Kompact rollers over the Classic?
See here: Kompact Rollers — Kreitler Rollers
Do the Kompact fit for usual road bikes (wheelbase)?
I want to store the rollers away in my flat after every ride, under the bed. Is the size so different or does it not matter?
Any other disadvantages/differences between Classic Alloy and Konpact?
Thank you!
