Fibre Lyte Gear Mech Plate Shimano Dura Ace 9000

Fibre Lyte Gear Mech Plate is a cool tuning part, available for all major Shimano, Sram and Campagnolo rear-derailleurs. Gear Mech Plates from Fibre Lyte are available for road bikes and mountain bikes.

In this article I will show you the design and installation of the FL Gear Mech Plate for Shimano Dura Ace 9000 rear derailleur.

Design FL Gear Mech Plate for Dura Ace 9000

On the Fibre Lyte product page you can read the description of the Gear Mech Plates:

“The Fibre Lyte replacement gear mech. plates are made from 2.4 mm carbon fibre, typically plain weave for Shimano and Sram and 2×2 twill weave for Campagnolo with titanium inserts for threads (where threads are required).”

In the picture above you can see both the FL Gear Mech Plate for Dura Ace 9000 (on the left) and the stock aluminum gear mech plate of the Dura Ace 9000 (on the right).  You probably notice that the I’ve ordered a version with a chain guide at the bottom rear derailleur pulley. There is also a version without chain guides and there is an ultra light version that weighs just 2 grams.

In the picture above you can see that the design and shape of the FL Gear Mech Plate for Dura Ace 9000 is almost equal to the stock version.

Installation Fibre Gear Mech Plate for Dura Ace 9000

The installation of the Gear Mech Plate for Dura Ace 9000 is a piece of cake and takes you 5 minutes.

  • You simply loosen the pulley bolts with a 3 mm. allen key, that are marked with #12 in the exploded view of the Shimano Dura Ace 9000 rear derailleur;
  • You switch out the stock gear mech plate with the Fibre Lyte version;
  • You tighten the pulley bolts, according to tightening torque in the dealer manual, 2.5- 5.0 Nm;

You can also do the replacement fairly easy when you have your (road)bike in a workstand with the rear derailleur still attached to the bike.
