I play a lot of invoker and enjoyed watching replays of w 33 , miracle , yapz 0 r , dendi , sccc and vurtune . <| sep |> Not much to watch out for , these fluid or simple trainers are pretty indestructible . If you want to do controlled workouts , you will need a power meter preferred or at least a heart rate monitor to gauge your effort , as that can fluctuate vastly on these trainers just with tire pressure . No need for a trainer tire , but trainers do eat tires , there will be lots of little black particulate around the contact point in a month of use . So I recommend mounting a cheap or old tire . Cadence is very useful , if I ride by feel I ' ll usually end up with an average cadence of 6070 which I have found isn ' t ideal for my performance . So I use it to force myself to spin more .
