I am currently installing a front derailleur as part of a new bike build.

It attaches to the frame via a braze on mount. I can't get it to shift onto the big ring. It shifts onto the big ring only when I'm on the smallest cog in the rear cassette.

Appreciate any help!

    Adjust the High-limit-screw on the front derailleur! – Carel Apr 3 '16 at 10:41
  • Have you used a double FD mech on a triple front chainring? – Criggie Apr 3 '16 at 20:14

It could be possible that the cogs and chainset are too far out of line. You might need a different bottom bracket. I had similar problems converting a ladies Raleigh Richmond to 21 speed. A new bb solved it
