When you aren't using the Cycle Hill you can just remove two bolts and the side arms fold towards the center, making it a nice compact package to store away. The bigger No-Mar changers don't fold up so easily. I also like that there is no overhead arm on the Cycle Hill, so you can swing the tire bar all the way around 360 degrees.
Here's the review from
WebBikeWorld that really sold me on this model.
If you do opt to buy one, go on
eBay where No-Mar is selling these for less money including delivery, and also throwing in the optional no scratch bead breaker.
