A Basic Shim That Does The Job Just Fine

By CMC-24

4 / 5

ConsA wee bit pricey

ProsWorks exactly as it should

A basic shim that enabled me to use my 31.8 front mech on a 28.6 downtube. Worked just fine and saved me having to buy a new mech.

It's a bit pricey for whatt it is but is still cheaper than alternatives from other companies.

SJS delivered it very quickly. I can't fault their service.

ConsBit pricey

ProsSolved tube sizing issues, perfect fit, nicely finish

Perfect solution for fitting a newer front mech to an older frame or reusing a mech you have to hand. Nicely finished and a perfect fit for the tube. Double sided tape to fit to the mech band is a bit of a waste of time, but a small glob of blue tac holds them in place long enough to tighten the clamp. Does exactly what you expect it to. A little pricey but cheaper than replacing the mech!

Can i use this to shim a Campagnolo 31.8mm band-on Front Derailleur?

By Paul

22 Jun 2018

Hi - I want to fit a silver Campagnolo Centaur Triple 31.8mm band-on Front Derailleur to a non-oversize 28.6mm frame, the height of the Campagnolo band is around 12.6 to 12.8mm. Should this band adapter fit okay? Thanks

SJS Customer Service:

Yes this should work fine for that.

Thanks

This is what I need I think, but I'm not sure about metal on metal. Won't it damage the seat tube?

Hi there,

If fitted and torqued correctly, this should not damage the frame.

Thanks

Height of the adapter

Hello,
original shim on my front derrailleur isn't available anymore, so I'm trying to find some replacement and actually the only dimension I would need to know is a height of this adapter. Thx for answer
Peter

SJS Customer Service:

Hi,

This clamp band adaptor is 12mm in height.

Thanks.

FD6700 from 34.9 to 28.6

By Ralf

Hello, there!
My bike is an old one which thin tube and it needs some upgrades. I have recently been given the 10 speed ultegra which has clamp with 34.9mm diameter. That is SOMETHING to start with, but the issue is the clamp is far too big. Can I use this one to reduce that big gap, please? If not, could you recommend something else?
Thank You!
Ralf

SJS Customer Service:

Hi,

To cover such a big difference you will need a thicker shim than this, the one we'd recommend is SJSC part number 43314.

Thanks.

I have a FD-2300 front derailier which is 31.8 and the tube I presume is 28.6 will this shim fit

By Gary

I want to convert or shim dura ace fd 7800 front derailler that has has a 31.8mm band on to 28.6 mm. Would this do it? Can I just buy a new 28.6 band?
