Help. Has anyone had experience with a Cervelo P2 SL front derailer cable routing? They welded a cut tube on the bottom of the bottom bracket and I can't install a traditional cable guide on the bottom of the bottom bracket. The front derailer cable has to route through this tube and is hard to shift with all of the friction not to mention the fraying of the cable due to rubing against the edge of this tube.

I know this is an obscure question but I've tried setting this bike up myself as I got it from the store completely disassembled.

Any help would be appreciated.
