Yep. I've had rollers for the last 5 years. I used them exclusively for indoor riding until I got a smart trainer last fall. Still use them from time to time when I'm doing a lot more outdoor riding and want to go inside to outside without setting stuff up on the trainer.

Have also owned a pair of powercranks. Now there's some gimmicky **** in the same vein as this "smoothness" stuff.

Thanks. I appreciate the reply.
