The Roberts works like that. I like it. a good mix of older and newer parts is a pretty good choice imho, the 'retro' stuff is often only superseded due to fashion or incompatibility (inbuilt!), not because it works less well, or is heavier. The cooks seatpost I have on my main bike is fantastic, best post ive ever used. And then there are parts like Salsa/DKG flip offs that have been around unchanged for ages, and they still sell, they are popular, they havent been 'improved', because you couldnt!
I rambled there didnt I?
