Moto2 championship leader Scott Redding has pointed to a total lack of rear grip as the reason for his slump in form this weekend as he slumped to 13th place on the grid for tomorrow's Aragon race.

The Gloucestershire rider looks like he will be in damage limitation mode for the second race in a row after title rival Pol Espargaro secured a front-row start in his home country.

"The problem was the same this afternoon as it's been all weekend; no rear grip. We tried to find something for qualifying, to improve rear traction through the faster corners, but we didn't really make any progress," said Redding.

"At the end I was struggling to find space on track for a quick lap. I did a ride through but came out behind another big group of riders, which meant I never got a clear lap in. In the end I think my fastest time was done on my fourth lap, which is a bit ridiculous. We need to look at everything tonight to see if we can find some more rear grip for the race tomorrow."
