These rollers just continue to shine. The oscillations while riding no handed I mentioned in the original review went away pretty quickly. I guess I either got used to these rollers or my technique got smoother. Also, they’re very easy to ride, more stable than any other rollers I’ve tried. The bike just seems to track nice and straight on them. Being able to ride absentmindedly is a big plus for those painful two hour roller sessions – the less mentally taxing the ride, the more abuse you can stand.
I originally said they were a little loud, somewhere between a fluid and a wind trainer. Ross Belloni of TruTrainer always disputed this, and he wondered if a bearing in the test unit had been damaged in shipping. He sent out a replacement drum, and voila, much quieter.
Finally, Kreitlers leave a glaze on my tires, a shiny grey sheen that looks like graphite from a pencil. This is especially noticeable on my yellow Tufo. For some reason the TruTrainers don’t do this. Is this because Kreitler drums have ridges while TruTrainer drums are glassy smooth? Does this has any bearing on tire wear? I have no idea.
Response from Jeff Rhodes of CycleDyne (TruTrainer):
The “graphite” sheen on your tire from Kreitlers is aluminum oxide coming off the rollers. It’s not the “glassy smooth” finish on the TruTrainers that prevents this, it’s because they are hard anodized. The glassy smooth finish does have a benefit. It reduces tire wear to almost zilch. Note that the tires don’t leave a black mark on the rollers.
No transfer of aluminum oxide to the tires, no transfer of rubber to the rollers. It’s almost a perfect world!
It’s really a great tool. The design and the quality is good. – Green Water Technologies
