Thanks for the kind words, I think folks must've gone easy on the tape as I'm a bit of a noob on this side of the forum
I'm very intrigued to try some different frames now to compare the ride, I don't notice much wag when pedalling but maybe I'm just not pushing hard enough yet! Mostly it seems to be through the front, all part of the fun though...
The Woodman post is 27.2, which is what I expected to need (can't remember why now, mombat maybe), 27.0 was very loose, couldn't have used one for fear of cracking the lug, but I did have to remove (file) a lip from inside the seat lug to get a smooth fit, about an inch below the top on the front side
Didn't remove any other material though and it's a good fit now.
The Rollamajig on the rear mech just cuts out the final loop of cable for a smoother run, necessary in this case for the horrible bindy cables I've used. Not the neatest look I'll be first to admit .. nice colour match though
Incidentally, if you don't want your's I love them for mountain bikes, happy to take it off your hands!
I think there may well be eccentric versions to alter cable pull (certainly are for brakes) but these are just round.
