nikos:
trainers can be quite boring if you let them. I got a cyclops fluid last winter. as you know our wisconsin winters have been mild the past couple of years so i did get out side a lot anyway.
The key for me is good loud music on the trainer, and having a goal to work on . I like to do intervals sometimes crank up the resistance and work on strength, or maybe just spin , Now that you got your A 5 you can work specific heart zones . 2X a week i teach a class using trainers during the winter basesd on heart zone training.
check arround mad town you might find one of the LBS has a weekly trainer ride during winter or just set it up in the basement or garage and ride.
the cyclops is arround 200 buucks a littke pricy but worth it a friend got one on sale for 155 though nashbar etc has sales on varrious brands chack the website and see what you come up with. oh yes i use an old slick tire ont he back with the trainer less noise and it will ware out the tire with use
