And on a recumbent with a hinged stem (such as my Bacchetta Giro) bracing with the hands is a Bad Idea! (as I found out on the test ride.....) Zebee |

And I can move the bars forward and back with one little finger while at rest. I have had the same experience on several other short-wheelbase recumbents with hinged risers. Basically, freely hinged handlebars can NOT restrain the rider from moving forward until they hit their forward stop, which is farther than the rider can reach while seated. So the legs and friction between the rider and the seat have to be providing all the restraining force to keep the rider on the bike while braking. -- Tom Sherman - Holstein-Friesland Bovinia The weather is here, wish you were beautiful |
