I wonder if any real advantage is not overcome by all the additional friction.<br /><br />I had an old Biopace on one of my vintage machines for a while. Frankly I regard it too as a (minor) piece of Rube Goldbergery. Never noticed ANY difference. I got it cheap, *really* cheap. The LBS owner found it in the cellar and it was coated in oily dust. I had just about worn out the chain rings on that bike and this was a stop-gap solution. Sudden brainstorm... I took the old (52-42) chainrings apart and flipped them over, like turning over old phonograph records, so the "shark teeth" point the other direction. It works fine, even climbing. I told the LBS owner and he looked a little worried. The chainring is 50 years old, and now it looks like I have found a way to make it last a 100 years. <br /><br />Following Phillip's line of thought, combining my system and the SDV, the sprocket market would stay stable as it is now.<br /><br />LeoAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8908461644259659419.post-70895296443078805092016-05-23T18:46:15.890-07:002016-05-23T18:46:15.890-07:00SDV looks like it would be quite a boon to sprocke...SDV looks like it would be quite a boon to sprocket makers. May I submit that the humble fixed gear is very good at pulling you past the dead spot in the pedal stroke as long as you have any momentum. I've always been able to climb better on my fix than on my geared bikes.Phillip Cowanhttps://www.blogger.com/profile/01553979458131339924noreply@blogger.com
