Hi,
After work on Friday I did one of my first full rides in the dark with my Classic, and took the opportunity to see what the bike and front light were like on the back roads. Conditions weren't the best - lots of leaf mulch and water. Some of the roads were more 'repair' than original surface and the tyres, while gripping fine, were giving all sorts of weird feedback.
I did think of responding to a thread that was started in the summer but was prompted to start a new one.
Is it more likely to be the front or back (or maybe both) causing the issues with the irregularities and tar infill? Again, I never felt like I was in danger of coming off (I was taking it easy), but it wasn't altogether pleasant.
