 The legendary Ratman retired his old bike and this is the replacement. He retained the low back end sled look this time using more appropriate materials. About the only aspects of the frame that remained the same or similar are the geometry, bottom bracket shell and dropouts. Pretty much everything else has been improved. The main difference between the Ratman and Britney frames is that the ratman was (is) large diameter .035" wall tubes and the Britney is made from smaller diameter .049" tubes. Another big change is the lack of square or rectangular tubing in the Britney. The Britney's thicker walled round tubing will hold up better to denting than the thinner, larger rectangular tubes of the Ratman frame. I added Gyro tabs, 990 studs and suitable cable routing but Ratman has been using only a front brake recently so these features may go to waste for a while until he decides to put a rear brake on.
