Shimano Cues Front Derailer - FD-U6010 - Read the description

This front derailer ships has a 34.9mm clamp with a shim for 31.8mm. If you have one of our bikes, it almost certainly has a 28.6mm seat tube, so you'll need to find a shim. This front derailer works fine with Silver shifters, although there's a little more throw than is ordinary.  This Cues stuff isn't something we'd ordinarily stock for the following reasons: It based around 1:1 pull ratios, or something other than the 1:2 that is necessary for happy friction shifting. This means you have to push the shifter more than is ordinary for a shift, which means when you're in the low gear, the shifter is at a crazy cock-eyed angle. Cues requires 11 speed chains, no matter how many cogs are on the Cues cassette. Our Silver cranks are compatible with up to 10 speed chains, so if we wanted to use Cues on builds for customers, we couldn't use our crank unless it was set up with a single ring in front.  Requires 113mm bottom bracket or wider. Why we have it: We requested 9 speed Shimano stuff
