Rollers

I have a question regarding rollers. I have had my rollers for two weeks and can ride/balance pretty good. However, when i go to do one legged pedaling drills on the
rollers the bike tends to surge back and forth. What part of my pedal stroke is messed up? And what kind of drills can i do to improve the stroke?

When i do spin ups on the rollers i get up to 110 and i start to bounce. However, on my
stationary trainer i spin up to 125-130 before i start to bounce. What accounts for the difference? BTW i use a cycleops fluid trainer and cycleops aluminum rollers.
Thanks.

The surging is from applying more force on the downstroke and not maintaining it though the bottom and back around to the top. Letting up on the upstroke and not continuing "over the top" of the stroke is what causes surges. You can also try one legged pedaling on the road or on the trainer where it's easier.

To some extent the trainer locks you in so you don't notice your uneven pedaling. Some trainers have flywheels. On the rollers any unevenness is amplified.
You can also try riding a fixed gear, either on the road or the trainer/rollers to improve your smoothness.
If you're really adventurous, try riding the rollers with power cranks.

That said, having a smooth stroke only really matters on the track. On the road you won't really notice one way or another.....as you you've already shown.

I would hate to see how bad i would be on power cranks. But i'm going to do my one legged pedaling on my trainer until i get better. Kinda funny,
i actually thought when i was doing spin ups and one legged pedaling on the trainer that i had a smooth pedal stroke! The rollers showed i
needed a LOT of work. Thanks for your reponse it was ver helpful.

This is why you need to do them on the rollers. The jerking and surging will force you to get better/ smoother.
Continuing to do them on the trainer will do nothing for you.

I agree that in general trainers reinforce "bad" pedaling habits while rollers force/reinforce good technique.

That said I know nothing about one legged drills, I always ride with two.

I'm taking your advice and continue to work on spin ups and one legged pedaling on the rollers. The rollers are forcing me to pedal
better which is what i need. Thanks.
