It is a replacement from a general isosceles triangle stand. After making this model, the frame on the front side of the stand, such as cleaning around the rear derailleur, did not get in the way and the workability improved dramatically. Fixing to the rear hub is also easy to install after the second time if the width is adjusted for the first time. I am quite solid and I think that COSPA is expensive. I am a little worried about rust, but it will be okay unless it is raining. It is a good product that you can say Minoula as expected.
