Hi man, many thanks for the video. Not only is it very detailed, but your comments are clear and extremely helpful. You convinced me that I should try and repair my shifter instead of buying another one!

Thank you for this very detailed and technical video.
I did the intervention on a dura ace which is very similar. Mine had an issue with the small shifting lever which was almost seized and caused the brake lever not to get back in place after brake release.
Once disassembled the small pin which holds the lever can be pushed from the housing. I used a metallic bruch and some sandpaper to clean the rust and reassembled it. I hope it will last 10 years more.

Probably the only YouTube Bike maintenance influencer who is willing rebuild and entire sti lever. Inspirational viewing.

GCN just spray GT85 into the internal shifter.

Only negative of this video is the annoying ads every 3-4mins.

Excellent presentation! The presenter is very clear, shows each step and explains them. Congratulation on a job well done!

[davemellor]

Brilliant video. Saved me having to buy a new shifter. Thank you.

Fantastic step-through. Managed to fix my shifter despite being a very green bike mechanic. Thanks!!

Thank you so much for that video. I still had a lot of trouble getting the shifter working but that was because one of the little springs that push one of the pawls had slipped out of position. Once I hooked the arm of the spring on properly, and with the help of this video, it works perfectly again !! 🙂

[MarioDallaRiva]

Like watch making! Bravo, Daniele 👏🏻👏🏻

Very useful video. I hope I can fix my st-6703 since it doesn't shift either up or down. After looking this video and seeing those tiny parts, I hope no part is broken in my shifter otherwise no chance for fixing. Thanks for this wonderful tutorial!

[lindsaygamble]

I hope that this video will be a life saver for my bike

[richardsharp]

Thank you for the video it helped a lot. You did not mention or show relocating the brake lever spring at the end when you refitted the lever. Best done before you finish locating the pin.

Now this was the video i realy needed. Thx man. Respect. Grtz from belgium

A heroic effort, thanks for sharing.
Back in the day when I wrenched/toured/commuted/raced, the most complicated thing I worked on was a Sturmey-Archer 3-speed hub overhaul. This looks like brain surgery compared to that. It is a beautifully engineered piece of kit.

Where were you 4 years ago when I attempted this on my older 6800, that's been sitting in a small box, in pieces, ever since?

nice guide, how do we dissemble sora 3500 rd?

[sparkeyjones]

I'd be forever grateful if you could do one these for the ST-6600. I think I can handle this procedure with one of your extraordinarily detailed set of instructions. But, if my 6600 is significantly different than the 6700 internals, I think I'd end up with a pile of parts and no idea how to reassemble them. 🤣

[alessandromenegardi]

Thanks a lot! excellent video! It worked perfectly for me!

First, how do they come up with this? Second, how to do they mass produce it? Quite amazing.
Awesome video, as usual.
