I know people here either love 'em or hate 'em but I'm willing to give one a try on my commuter, mainly because I'm tired of leaning it against things only to see it topple over and to facilitate loading my panniers.

Please suggest a model that does not clamp on with steel jaws that will scratch the paint. I have no mounting hole near the bottom bracket, so I think it will have to clamp onto the chainstay.

Thanks
