Got my rear derailleur down to 155 grams from 167. Should save another 14 with fibre lyte pulleys. also need to replace the main bolt. That might save 3-4 grams im guessing? Let me know what you think!

A sram red rear derailleur stock is lighter by 13 grams over your tuned model.

You could also say: "hey that is some great tuning work!"
Sure, a stock red is lighter, but this is what WEIGHT weenies is about. I'm happy to see somebody who is putting this much effort in tuning.

That is like what i've done to mine. you should leave out the barrel adjuster, should save a few grams there. I used the thin ferrule from the dura-ace cable set.
I don't need that adjuster as there's one on my frame's down tube. No need for two.

I actually got the cages down to 4 grams each. I removed a lot of material. I would be worried about the durability on those 2 gram cages haha

Awesome thread! Great work!

I too have a Fibre-lyte cage from Stephen, he has been great to deal with.

Ive got Ti pulleys and Ti bolt kit.

I must say, it never occurred to me to remove the adjuster itself?! Thats a great idea, and one Im going to try out!

Love it!

Looks the business.

I might take my dremel to a spare 105 derailleur to see how light I can get it. Nice work.

Good to see some gems still pop up on WW.
