2.0 out of 5 stars.  Possible design flaw?, June 4, 2009
By Wendy Wolfe (WA United States)
First off, I like Minoura products. It's just that it appears that this unit has a design flaw.

Specifically: There is only one thru bolt which connects the two black plastic portions of the unit to one another. This means that the unit is unstable & can "walk"... should this happen: the two black plastic pieces tilt up where they join & act as a brake on your rear wheel. No option but to dismount & fix. Depending upon how aggressive you ride - this may be every 30 seconds or never.

Additional details:
* My setup is on carpet, with a yoga mat under it. Based upon what I'm seeing, the unit may be OK directly on a hard surface, but don't hold me to it (I've not tried it)
* I'm an intermediate level rider. Semi- but not super-aggressive. I'll stand for "hills", and I get bored if I just spin for the duration.

If the unit had two thru bolts, this would not be a problem. Alas, it does not. It has just one & so I give it a cautionary score.

Like I said at the beginning, I have no issue w/Minoura, it's just that this model might need a little re-work.

5.0 out of 5 stars.  GREAT TRAINER!, January 20, 2010
By Craig Tuggle (Greencastle, IN USA)
I absolutely love my trainer. I have been using this trainer for over 2 years. Because of the gravity wheel engagement design, this trainer does not wear out my tires. In fact, I have not replaced a tire on my bike for 3 years and still have plenty of tread. Many other trainers I have seen increase the resistance by squeezing down on your tire harder (threaded hand wheel increaing force on tire). This trainer does not work that way.

I trained for several triathlons including a 70.3 half ironman. I have ridden for up to 4 hours straight on this trainer. It feels like riding on the road. It is a little aggressive in its resistance, so it feels like you are biking up a slight grade all the time, even in your lowest gear. This will only make you a stronger cyclist. The mag / hydraulic system is smooth and quiet. The resistance appears to be proportional with gear selection and rpm cadence. Flaws....none. I highly recommend.

I am 5'6"" 150lb male riding 3 to 5 times a week. I ride a Quintana Roo Seduza 2008 and a Fuji Roubaix 2005.
