From the description, this is a new type of trainer, but I'm not sure how the resistance is being generated, since they say it isn't magnets or fluid (and I'm assuming it's not a brake pad either), but "centrifugal force". The claim is that this has a more road-like feel than a fluid unit. I'd appreciate anyone who has ridden one of these to confirm or refute that statement.
Followup to my original post:
Saw a review on Pez today for the Blackburn Trakstand Ultra. It appears that Performance licensed this technology. Looks pretty cool from the review and Blackburn's web site; essentially this is a centrifugal clutch that increasingly presses the flywheel against a friction pad. The reviewer thought it did have a nice road-like feel and good resistance.
My concern with it is that for more powerful riders, you need to add more ball bearings to the flywheel unit; not sure how this affects rideability if you aren't cranking out the watts. Also, I'm wondering about the longevity of the friction pad, though it doesn't sound like that big a deal to replace.
Anyway, I'm going with a Kinetic Pro. Just the flywheel on the Pro weights almost as much as the entire Blackburn trainer. 😄
