Here is my carbon front sprocket cover, it has the reinforced brass sections for the bolts un like the cheaper ones that are sold so won't crack when you tighten it ! In good condition. £25 posted.
Any chance you could hold this for me mate until Monday (away until then), want to check if mine has the brass sections - if it doesn't i'll take yours? Mine was a nightmare to fit too, a real struggle to get it to line up.
