Hi, It looks like the 2nd generation (rounded and engraved logo version) of the "2000" brake had the same reach as the "Racer" brake. So, I guess that the "2000" model could be described as an up-market version of the "Racer". To the eye, the extra reach versus the "Competition" brake is around 7mm. This is not an exact measurement though. Hope this helps. All the best, Peter Rogers
