Astralites Jeff spot on.
The front 19 inch J wheel fully loaded together with the 18 inch rear j wheel similarly fitted up is 36KG's
The front 18 inch Astralite and 18 inch rear Astralite set the same as above are 29KG's
Doesnt sound like a lot put like that but 15. 4 pounds is a lot if you try to save weight anywhere else.
The added bonus is that they have bigger tyres on so in real terms the saving is a little more.
It worked out at about £100 per pound
If i get some time i will start my own thread with pictures but my first meeting is four weeks away and still much to do.
