I'm guessing the inner chainring sandwiched between the 77t ring and the outer ring mount is there as a spacer to stop the 77 from hitting the chainstay. Maybe we could club together and buy Nik a longer BB spindle? :-)
Correct. I already fitted a long B/B but still rubs when I put the power down so spaced out a bit more with the inner ring. Not ideal as the chainline is a bit out. Unfortunately the Felt chainstay flares out right from the B/B area.
I went to watch (some of) the 100 mile time trial at Farnham on
The winning time was some three hours and 43 minutes, by the man with the 77 tooth chainring above. The bike looks quite home made with a bizarre saddle and stem.
Goes with post above - haven't got used to the controls yet
