Campagnolo C-Record クランクの専用フィキシングボルト工具と注意点

A dedicated tool is required to install the fixing bolt on a C-Record crank. Pin spanners aren't really recommended. It has a somewhat tricky design where mounting the bolt to the crank uses reverse threads, while mounting it to the BB uses standard threads. If you break it, repair is virtually impossible, so if you don't understand how it works, it's best not to touch it. http://t.co/itURW2Aw
