So I prefer rollers but cant use them for most of my workouts as I simply cannot erach target wattage.
I use a set of Roodol compact with 2.5’’ rollers, Id go to 2.25’’ kreitlers but they are silly money and I dont think theyd make a huge distance.
My FTP is set at 290 so id have to be spinning to 140 for minutes at a time to reach some targets which although I race track is all but an impossible ask, and stay safe!!
Im in the UK so some makes of ‘resistance’ rollers I just cant get here (was particuarly interested in the rollers that increase resistance as you spin faster but no one stocks them UK)
