BITD the early trainers were rollers, with esentially no resistance when riding them. Some one came up with the idea to use a pair of squirrel cages/blower fans to add some resistance. Racer Mate first made these attach to the back side of the seat post, running off the top of the rear tire. There was a bike holding stand too but you could use the resistance unit while riding rollers. A racer type I knew would ride the road with the resistance unit for his training. I made a version of the unit and would use it if the seat post clamp was compatible with 27.2 posts (the post I designed it around was about 25.? on a late 1960s Frejus track bike). Andy.
