Thanks folks, yes it’ll takesome getting used to. Next problem – the steerer tube. A traditional looking steerer expander bung has been provided, as has an ‘air cap expander system. According to the instructions a sleeve is glued in place and then a simple top bolt plugs in, allegedly holding all in place. This seems a bit insufficient to me i suppose, and cant fathom why it is there in addition to the expander bolt. It has to be glued in tothe steerer, so once its in, well its in for good….so im a little nervous about doing it. Does anyone have a pic of their steerer setup, ideally showing an expander bolt setup or the aircap setup?

An idea what people are using and pictures would be really appreciated.
