I went to remove the crank arms from my Corratec shape pro hybrid today only to be halted pretty much straight away.I removed the 2 bolts from the left hand arm and then had to remove the plastic screw on cap from the centre,no tool and Halfords dont know what size i need,its a very large black plastic torx cap that screws through the arm and into the bb,does anyone know what size torx i need or where i can get the correct removal tool,i tried a flat blade screwdriver but there was a risk of it chewing the cap up.
Cheers.
