I'm not sure what model handlebar this is, but it is very nicely shaped. The seller says these are rare? Track bars? Take a look. The most elegant handlebars I have ever seen were on a exquisite Herse track bike. Few Herse track bikes were produced, right Jan? People don't or can't do that bar work anymore. Those curves were alive!
