thats why i have on occasion passed gaggles of slow moving of AM full sussers (going up and down)in Epping on a hard tail retro pile of crap. right tools for the right job and all that.
I've passed gaggles of folk on boat-anchor retro's on a Lappiere AM rig, including some chap on a nice lookg olde Trek just this morning (red Trek steelie, mid 90's looking, 'hello' Sir if youre reading, I think you may live in the same village). Right tools for the job, and all that.
If someones bobbing up and down on a modern bikes its either a cheap and nasty, or they havent got a clue about setting up suspension, probably the latter these days. Fully floating suspension, such as Maestro or Pendbox, isolated the transmission from the suspension action half a decade ago or more.
Where have you guys been all this time?
Next you'll be extolling the virtues of leeches over penicillin. I mean, I love the old tin, the feel, the history, the differing design strands, the sheer nostalgia, but we wont be seeing the Athertons reverting to an early 90's Alpinstars in the hope of going quicker anythime soon.
