Fluid Trainer
Considered the ultimate indoor bicycle trainer, the fluid trainer tends to get the highest ratings from professional cyclists and consumers alike. The idea behind a fluid trainer is to get as close as possible to road like conditions. What we are talking about is correct resistance and in some cases the trainer will even have the ability to rock back and forth (which is what you don't want in a ride but teaches you correct form).
Fluid Trainer versus Other Indoor Bike Trainers
In general, a fluid trainer is much quieter than a wind trainer and offers better resistance than a magnetic trainer. The one major issue seen with fluid trainers is that they sometimes leak, but over the years the manufacturers of these fluid trainers seem to have resolved this problem.
Fluid Trainer Offers The Ultimate Indoor Ride
Lets face it, in nearly all circumstances we would rather ride our bike outdoors than be stuck indoors riding our bike trainer.
However, there is a period of time (called winter) when some of us are literally stuck indoors for a period of 3-4 months where if we want to stay in shape, we may as well ride our bike trainer. Some of us also get into either extreme heat conditions or what seems like never ending periods of rain. So, if we want the best bike trainer, we need to be riding a fluid trainer.
