Shimano XTR M971/980 Front Derailleur Clamp Shim 31.8mm

Cheap plastic

This is worth about $1, not 10 times that amount. It is not carbon fiber, or UV rated HDPE. It's just really cheap plastic that will likely rot in one summer of AZ sun. Will use soda can homemade shim instead. Just another cycling product ripoff.Read full review

Swell derailluer shim,

This enabled me to fit a front derailleur on a Calfee that had a 33.15 mm diameter seat tube.

Nice and sturdy support

Used it for a cable pulley I added for the front derailleur set up and so far it's holding up very well and sturdy. A good product.

Works great

Worked well with my ultegra front derailleur which i got for a great price. Just a bit thicker than the clamp but still fine. Save me the trouble of getting a replacement derailleur.

The shim doesn't look like much but does the job quite well.

Wrong geometry for alignment

Yes it works as a spacer but does not align or push the FD out to the gears as needed. Maxed out not on the bug ring. So this is useless!!
