Interesting comments on rear braking and 66kph by 25hz
http://www.recumbents.com/forums/topic.asp?whichpage=1&TOPIC_ID=4226#32871
All of pythons with front brakes are coaster type. I tried rim brake on 24"
front suspension, but it got very rough, maybe because the front pivot was very
weak. Has anybody compared drum/disc/rim brakes on the same wheel/bike?
