Weight Weenies

Hi everyone. I've seen some mods done to the Shimano 7700 and 7800 rear deraillier, and one of the steps is to disassemble the entire piece. I got most done, but the hinge pins that are captured are a bit tricky and all the mods no one explains how to do this. The first photo is mine and the other is a mod posted online.

No mechanics here? ha ha,

My guess would be that you hammer them out with an appropriate sized punch. But I'd wait for advice from someone who has done it...

I recall seeing a tuned one where the pins had circlips on the ends.

I never understand how people are able to cleanly remove these one way pins. more annoyingly, they never tell how they did it! My only guess (and i thought about doing this) is to drill a small hole on the opposite side to enable a small punch to go in and knock it out. I took the pins off of my Sram force Rd but the difference is those pins had (hats?) or ends to them that can be pried out with a wedge tool.

Yeah, I racking my brain trying to figure it out. May just drill out the other side and c-clip it in in the future or something. No one shows how.

Perhaps you could drill and tap a hole in the end of the pin. Then use a screw and some washers to extract them.

I'm also looking to remove the pins of my Force RD. Could you give some more information how you got them out?

Same question here. Help us out. PLEASE

I got mine out of the force derailleur.
The ones that link the plastic P-knuckle to the magnesium link of the parallelogram can be pulled out quite easily: just pry a little screwdriver onder it. It will damage the aluminium and magnesium a bit, but you can sand it down afterwards.
The 2 other pins are soldered, so they can't be pulled out. But if you drill in the whole where they are soldered, you can pull them out fairly easily. I will post a picture of this later.
