All cut up. How are your tires?
Take a look at the pic below to see how the Marathon Plus 700 x 35c is holding up after 3,500 miles on the back and 700 on the front on London roads and abrasive fine quartz and limestone loose gravel-covered bitumen paths. Running at 85 PSI
It's those micro gravel and metal chips that wedge in the compound (once it starts to wear down) that really do the damage, moving around with every rotation, digging deeper and deeper into the compound.
And if (unlike the Marathon Plus) there's no thick puncture resistant breaker between the tread and the tube, flats are the order of the day.
