European GP: Kerb problem puts Baku under cloud

Baku, Azerbaijan - Baku's inaugural grand prix is under a cloud due to a worrying problem with kerbs at the brand new street circuit.

GP2 qualifying was postponed on Friday, with Germany's Auto Motor und Sport reporting that 90% of the F1 cars in opening practice suffered damage to their tyres.

Loose kerbs

With the subsequent GP2 session red-flagged, Charlie Whiting and his delegation inspected the kerbs and found them loose and with sharp edges.

At the unprecedentedly-fast, wall-lined street track with small run-off zones, the risk of failing tyres is a major problem.

Sauber's Felipe Nasr: "I got my puncture on the lap Ricciardo crashed. 

"When I wanted to get back on track they told me the left rear tyre was damaged and we had no more," added the Brazilian.
