This morning, thrashing the bike along a curved accelerating lane (that's what they're for right : accelerating
) in 2nd or maybe 3rd, I felt a massive wobble.
It was not fast enough for the aero to be blamed so I thought I had it right about the rear tire.
Tonight I checked and it turned out it was very low on pressure so I was half right ...
But it is shot anyway.
I just can't make my mind around big fancy swap of the rear end that is gonna see my bike off the road for a while or bite the bullet and get a tire fitted wich lacks the bling factor and should prove a problem on my quest to a massive gear reduction ratio.
As of today I have a 16*39 on a 3,50 / 16" wheel and apparently I could adapt a RGV 250 37 tooth sprocket but it is still a long way to go for the 8500 rpm / 100 mph combo I am looking for.
Calculation is at work but on the top of my head, but it would require a minimum rear wheel size of 17" fitted with a 120 x 90 tire with the 37 sprocket to match the target.
18" would be even better since it would allow me to keep my 39 sprocket.
