It is in near perfect condition. It has the non-round rings Shimano used at the time, Bio-pace as you refer to. Honestly, I can't tell much difference. But then again I've no power meter , nor am I a pro level rider. Seems like one of those fringe ideas that never really move forward, even though there may be merit. Bicycles tend to hold to a core of tradition."Jim Langleyhttps://www.blogger.com/profile/04184699406623972210noreply@blogger.comtag:blogger.com,1999:blog-6752457184418512360.post-87256100497200375382011-11-19T06:28:14.216-08:002011-11-19T06:28:14.216-08:00Jim

I switched to Rotor Qrings a few years ago and love them. I have several bikes and put these rings on the two I ride the most. A couple of my bikes still have regular rings. Without any doubt I can climb and TT faster with the Qrings. I don't think it's all in my head but even if it is who cares if it makes me faster. A good test would be using the new pedal power meters on the same bike and same rider and changing out the rings over several rides.<br />GipperDPOhttps://www.blogger.com/profile/12425192613300523110noreply@blogger.com
