Just a quickie…so I don’t have to mess about sending it back if it’s wrong..Would the Shimano SLX Front Derailleur Top Swing M665 be the correct one for the 456 frame?

Also, struggling to find a 29.8 QR seat clamp too… any suggestions?
Thanks folks.

dunno about the mech but a 30.0 surly or salsa seat clamp will fit.

top pull 28.6 is what you need for the 456.

30.0 is fine for the seat clamp – plenty of them here: http://www.chainreactioncycles.com/Categories.aspx?CategoryID=212

What size frame? (On a 16″ one the cable stop on the seat tube was too far down for a top swing mech -made the exit angle of the cable too steep so it wouldn’t work)

It’s an 18″ frame, it does specify “Top Pull” on the On One website but just want to be sure the M665 is it.

made the exit angle of the cable too steep so it wouldn’t work)

It might look like it won’t, but in reality it usually will.

Sorry, I may be getting confused between top swing and top pull, last new front mech I bought was when I built up my 456 three years ago so not really up on which is which. The old one had the band above the cage if you see what I mean and because of the angle of the cable it would just about change up, but only if you had the strength of king kong in your left thumb!
