THE GEOMETRY DEVISED FOR THE RECORD? ULTRA-SHIFT FRONT DERAILLEUR INCREASES ITS RIGIDITY. The body exploits the M-brace form & is compatible with both standard & compact cranksets. The clamp fixing it to the bicycle frame has also been enhanced for greater versatility (Even-O). Ultra-Shift front derailleurs are more rigid while thanks to the new chain guide fork the operating speed & ease of use & adjustment are enhanced. Furthermore the anti-friction treatment extends their lifetime. The fastening system has also been redesigned in the clamp versions for enhanced compatibility with the bicycle frame.braze-on clip-on: 32/35 mm for double standard & CT cranksetmax capacity 16t max chainring 54t min chainring 34t composite & aluminum fork
