With the name Hydrogel, I'm assuming that it's fluid trainer. Does it have any type of resistance setting? If so, you may want to play with a few settings until you find the right one. I don't know of too many fluid trainers with adjustable resistance, but that is one of the things I really like about a magnetic trainer. And with a remote control for the resistance, mine can be changed, as needed, while pedaling.

They are quite different than riding the road, but better than nothing in bad weather; just a little boring at times. They are great for rehab, too.
