I just replaced a set of D606, noisy even thru earplugs. These are Kenda K-270. This is the rear one at 4634 miles (I ride like
). Some have said the Kendas are wiggly, but I didn't notice until the front one was nearing bald and I was experimenting with raising my forks in the triples for a quicker turn in at the same time.
It was also mentioned that the Shinko 244 has a heftier shoulder knob and looking at pics, it does. So I'll be trying a Shinko rear next (just mounted a Pirelli knob on the front).
Kenda K-270 (5.10-17)
I wanted to post this anyway.
