I recommend this product
It does what it says on the tin, i.e. works very well for a 3x9 set up and in my case a 'large' chainwheel size of 44. Good on SJS Cycles in stocking it because Wiggle and Chain Reaction and others didn't stock anything else suitable. Shimano online manual good for setting it up

Chain Stay Angle

You say this is for 66-69 degree chainstay angle but I think the Shimano documents say it is also for 63-66 - please confirm compatibility?
Hi there,

This particular one is for 66-69 degree chainstay angle.

Is this a suitable replacement for Shimano SLX FD-M660?

Looking to replace front derailleur from a 2010 Whyte 19c which came with a Shimano SLX FD-M660. Are there any better matches?

Hi I have fitted a deore 9 speed triple 48/36/26 on my genesis tor de fer. I'm currently using a sora fd 3034 front derailier which has seen better days. Could I swap it out with this front mech.?
Yes this should work fine.

Useable with a 50 tooth chainring
06 Feb 2018
I know the stated maximum size ring is 44-48 teeth but would it accept a 50 tooth setup with a maximum capacity of only 12 teeth -38-50)
Thanking you in advance
Hi there,

The max ring size is 48t.

Can I use this with a 48/36/26 chainring? Thanks.

Hi there,

As the description reads "Maximum capacity of 22 teeth, and up to 48 tooth chainring"

So yes, using a 48t big ring means the smallest little ring you can use is 26t.

Shimano Deore (Fd-M511) Ill This Replace -
18 May 2017
Can this replace existing believed-to-be FD-M511 9 speed, TOP SWING DUAL PULL DUAL ISIS on my GT Avalanche 1.0 2004 please ?

We have looked at your bikes specs and can say that it should replace your existing part. However we do not stock this bike so we have not tested this.

Hi, yes this will work with a 44/32/22T 9 speed set up with no problems & is a clamp on derailleur.
