Any question answered...

Won't work. You need the spiral coil 'pipes' for Nokon that go under bar tape to add to the extension kit. You can get them separately special order from Germany but they're £8 ish a pair and long lead time .. I bought some about a while back to use with all the odd lengths of left over Nokon rather the buying another complete kit.

Choices I know of Ed are :

I- links
Nokon
Powercodz Swift
Aican Bungarus

I've only used the first two on that list and favour I-links. IMHO it's easiest to fit, gives a tighter bend and the anodising is better then Nokon.

Well bugger I order the short cable one, ah well.
