Hmmmm....thanks for the concern guys, I'd had thought of this during the installation even though the catalogue does not show any setup at all.
I've just been able to get away with this installation even though my Brake and Clutch cables were changed for braided ones by a previous owner and I'm sure they are slightly longer than std.
Any other mods e.g. straight / 'streetfighter' bars or Lucas type raiser kits would need ALL the cables lenghtening and would be quite a bit more time-consuming.
YES
Old age is creeping in, my back certainly thinks so !!!
I dont have any doubts on the install - the clamps are really solid (well....would 50mm be anything else!) and the Renntec bars I deliberately went for have a 4mm wall thickness.
The only thing I would of liked would be been to be able to fit nyloc nuts on the vertical bolts - but the way the edge has been chamfered prevents this.
At least I can go back to standard if it does not offer a stable setup, which I probably would do rather than go to a yoke kit as I prefer the Clip-on type look.
Cheers - Frank
