I've lost about 0.5mm over the last 1350 miles. I rode alot of mountain passes some at speed and the tyres and bike took it all in its stride. I've managed to round off the tyre profile and used the entire tyre front and rear. Very impressed with the STR's.
We travelled in a group of seven bikes with steady riding 95% of the time. Averaged over 60mpg.
I managed a little off roading up a mountain track along side a ski lift.
Pretty steep and off camber with loose gravel. I nearly came unstuck loosing power near the top of the climb due to tc being set to high.
My mate on his Tracer wasn't so lucky. No damage but couldn't go up or down.
It took two of us to right the bike and turn it down the slope.
The bicycle below were at the top of a Tour De France climb. The wheels were around 3m across.
Bottom left is the top of bottom right.
10 miles of down hill towards France.
