Hi Team GP. Thanks Great info on set-up and the reasons for using it. I am a bit puzzled by the 9.6%. What gearing do you use on the side belt as the highest % I can get is 8.7 - with front and rear tyres the same diameter. I must have overlooked something

Thanks Proffar,

Up to now we have been running 18/25 but the side belt is very loose, even with full adjustment. That is why I wanted to move to 19/26. !9/25 would be perfect as far as belt tension is concerned but gives too high OD ratio.

What tire sizes do you run with 18/26 and how do you make allowance for rear tire wear during a 20 to 30 min final

Thanks
