An RD that weighed 1kg and sold for $890 would score the same as DA You want weight SAVED/$, so you need to start with a reference point like DA or Ultegra... _________________ Graham

About the same weight as the LW, but much less expensive: http://www.cyclingtechblog.com/2008/12/ ... erailleur/ _________________ www.cyclingtechnology.com (NOTE: This poster owns a retail business selling weight conscious bike related products.)

Here is one that Boonen (from w.w's and FWB forum) did for a friend of his....119g. http://fairwheelbikes.com/forum/viewtop ... f=6&t=5621 _________________ Used to race....got too wrinkly and old Updated: Racing again!
