Jammed / bad shifting Shimano Ultegra ST-6700 10 speed shifter. Full rebuild.

[@danielribas1109]

That's the first time I watch a maintenance video and my conclusion is "i wouldn't dare trying to do it by myself, even with a video to guide me"

[@turbotonic27]

Thats bad

[@danielgembski4487]

Same here 🙋🏻‍♂️

[@thepie4052]

7 attempts but finally did it. Fantastic video, thank you! 🙏🏻

[@bikemattic]

Thanks for this! My cable broke inside the shifter and jammed it, and I couldn't get it out. Your video helped me get it working again.

[@luigibirillo6629]

Thanks, great video. I used your video as guidance when servicing a Dura-Ace 7900 right shifter. However, what a pain. It took 6-7 hours.

[@aikedirkzwager]

very nice! It works again. Thanks very much for putting such work in it and putting it in you tube!

[@koko_5662]

Absolutely amazing g to watch. My front shifter jammed and this gave me a lot of interest to take it apart and look. You’ve done something many would tell us impossible… ти chain bike shops. 😄

[@SpokesEtc]

Thank you for this video, was able to save a customer's shifter because of it.

[@SindreOsthagen]

Thanks for the detailed video! This is helping everyone making bicycling an even more resource friendly way of transportation activity. I enjoy you enthusiastic and insightful approach to this sport.

[@davidburgess741]

Thank you for reminding me why I never owned STI brifters! I've had LX rapid fire shifters apart despite the staked screws and corrected the spring that slipped off its stop. Lately I've taken refuge from technology by riding fixed gear only!

[@nick37781]

crazy high quality video

[@fthat8260]

Dude i have this exact problem at this exact shifter, your video will be a huge help thank you so much

[@stephanelouvet1113]

Nice ! with this video I repaired a jammed shifter (one pawl we see at 10:57 was stuck by rust) ! Thank you so much ! Few remarks though. 7:52 - This main shaft is secured by a pointy pressure screw. This tiny screw (1mm Hex) is located deep down the hole where you secure the side cover 17:59. Then the main axle is free to slide out. Not need to do this move at 8:12 11:26 - There is also this centering pin which is locating the 1st block in place. The pin goes into a hole in the white plastic PCB support. 14:26 - It has been easier for me to place the trust bearing on the other part we see at 14:43 as it was well centered then. 14:58 - Mention we have to place the pawls under tension when reinstalling. We see you do it, yes. But a commentary would have help. 17:03 - I think I forgot to reattach a spring helping the brake lever return movement. I'll have to remove it again.

Great whatchmaker's skills

[@joeyjoey7972]

Great video, I have a 5700 right side shifter that is jammed , this is similar but still I'm having issues ldown shifting are rebuilding

[@felipemolina6370]

That's smart and effective work. thank you for posting this helpful video.

[@imsoniceee]

I have a similar 105 10 speed with the problem you described at around 16 40 mark, Shifting down . I opened it up and I can see the problem, the down shifter doesn't stay down. After shifting up if I push the whole mechanism down it will work if I don't push it down it wont shift down. I need to tighten the mechanism but I don't see any screws

Muchas gracias amigo, he podido arreglar la maneta gracias a tu video 👏👏🙂

[@Marc_B.]

I got a used ST-6700 right shifter, because I couldn't find a replacement spring. Works good, but the grease looked worn, and dirty. I heavily degreased with White Lightning, air compressor dried, then sprayed TriFlow. I think taking it apart would weaken the existing springs. I'm considering cleaning it again, and getting a mini grease gun to replace the TriFlow. I won't be taking it apart. One thing I noticed with my broken shifter, and my new/used shifter... when shifting to the larger cogs, the mechanism inside seems to wobble a bit. It looks janky. I'm not sure if new ones are like that, or if it's a wear issue. This does instill confidence, and I surmise that this unnatural movement could be causing the return spring to eventually break.

[@BleakVision]

Loved my bike with 6700! But wait a minute, there were electronics in the shifter, like in all of them? Never ever heard about that or noticed it.

[@otorres36]

greetings. I have some sgimano ultegra st 6703 words and the one on the front does not apply to download. Any tutorial that can help me????

[@manuelpordomingolopez319]

Excelente. Muchas gracias!!!

[@jbean530]

Do you work for Shimano? That is really complicated. My shifter on my second bike stopped working about 8 years ago. I started to take it apart but couldn’t fix it. Hopefully, I can find the parts and try again. Wish I saw this back then. I think I miss my vintage down tube shifters. I could actually shift faster with those things. Haha. Good job.

[@cabaneencac5168]

I end up here cause my almost brand new ( only 500km ) STI 4700 Tiagra whose small circular spring has decided to dislodge its end from its small hole making it so that the pawls no longer want to brake in each notch of the ratchet. In the upside down position which allows me to remove the bigger cover which is below the rubber hood , the pawl engage just by gravity but we can clearly see that he is loose and that nothing applies pressure to him so that he stays in the notches.it's so small to see that I can't even tell if the end of the spring is broken and if it is possible to reinsert it in its stop hole. Real Swiss watchmaker job that you can do ....Tabarnak long live bar-end shifters

[@racerboy696969]

Excellent video !! One of the best tutorials i’ve ever seen on KZbin. Thanks !!

[@HectorIgnacioUrraUrra]

the video is phenomenal, congratulations. I'm trying to open my 6700 right handle, it's stuck in the N°10 click and doesn't want to go down, do you know why this happens? in your video I've seen that it must be left in the lowest position of the pinion to be able to start disassembling it, I hope that you can help to me please.

[@mennoliefstingh5687]

did you ever figure this out 🥲

[@biking-places]

now that i've serviced an integrated shifter i think i can disassemble a nuclear reactor with my toes

[@jacobg1988]

Love these explainer video's!

[@pedallinraw]

Nice job! I have a few of those levers and there was a bad batch one time where the plating process was poor leading to rusty parts....🤷🏼‍♂️😐....those levers are still going ok though 👌🏻not really too much in there once apart 🤓

[@KacsaFacsaro]

can you make a video, how can I disassebly the brake lever unit? 3:32

[@hansbeukers7725]

Well done. It helped me a lot. I wonder what the meaning is of the electronics .

[@janegj4803]

Is there a manual for these repairs, and if yeah where can I find it?

[@leodirectvleo1703]

You are really good!!! Thanks!

[@lebronjay6473]

may i ask what is the size of the rectangular head screw under the clamp band? i’ve lost mine and i don’t know what size to buy. TIA

[@balkans01]

Nice video! I found that circlip extremely annoying to remove hahaha Oh, and after disassembling, then cleaning, I discovered that the reason my shifter had stopped working was that the plastic hole which houses the biggest tension spring broke in half, so there's nothing to insert it into :( Also explained why the end of the spring was warped and bent....

[@ergonzales]

Nice! Thanks, as always!

[@chadlove3443]

What is the part at 11:54 called. It's the white plastic piece that the shift cable goes into and pulls the cable tighter when you shift gears up.

[@badger0888]

Amazing step-by-step tutorial. I stumbled on your page with the new product for ugrading SRAM 11 to 12 with a simple ratchet swap. I wonder if it could be an option for the more complicated Shimano brifters @

[@renatorondon5471]

Congratulation my friend 😮 wow

[@andreapalazzi670]

Great video, but can you explain better how to remove the seeger at 6:40 ?

[@iffy_too4289]

What are the orange and black screw drivers you're using?

[@markifi]

what was the szajbaze debacle another person here kept commenting about 9-10 months ago? could you tell us your perspective? (10 speed ultegra disassembly is something i should do on one of the bikes)

[@renegadeflyer2]

I've been trying to rebuild a ST 5700, 105, RT shifter. I've have been trying to remove the brake lever pivot shaft. I can not find the sir clip like the Ultegra shifter. I was wondering if you would know how to do it and Maybey give me some info on how to remove it. Thanks for your informative videos.

[@Marc_B.]

That last spring (called the return spring) that he installs was broken on mine. Don't know where I'll find another without buying one 'for parts.'

[@jayscount]

How do you adjust the shifter height for this model please? I cant find a video for it online ?

[@luigibirillo6629]

Is there a way to put the shifter mechanism into gear 10 if the ratchets skip? Without disassembly?

[@parkstraat9]

What grease do you use? The link is not working anymore

[@hicham88ify]

Hi thanks a lot for the video I lost the spring that you install in 13.49 Can you give the specification of it Or a link that I can get it.

[@thomasbergefoyn2559]

Excellent video!! I found out that the "smalest spiral spring" left in the "frozen video image at 09:09" was broken. Does you or anyone here know where to get spare parts like this from Shimano?? It would be amazing to fix this without buing a knew one.

[@GNX157]

The best bet would be to look on eBay first to see if anyone is selling a “parts only” shifter, and see if you can find out what is broken about it. I have one here but same as you, springs are broken as well as a pawl pivot worn.

[@thereisnoiindaly]

@thomasbergefoyn2559 or @sickbiker Did you find a replacement spring? I'm looking for the same part right now.

Have you ever come across the stuck shifter problem on the R8000 left shifter? It can't be taken apart as easily as the 6700.

[@Bandyrobs1]

Brilliant..how you got that all back together I’ll never know! 😂

Is there any chance you can do one on rebuilding an Ultegra 6600 10 speed shifter?

Yes please, I need to rebuild one of these myself.

Is there a way to change the lenght of the cable pull per click?

[@emmanuelbusiello9953]

beautiful video , but the grease on the brass electrical contacts absolutely not

[@haroldrull4943]

Nice, maybe you can clean my Shimano STI too. Very well meticulously done🧐

[@anominous838383]

what kind of grease are you using?

[@yakazoko3856]

I need the same video but for the 8020 shifter and can't find it, plus this one doesn't help me. :/

[@Dutcharmytent]

Please can you do a video on how you film. Can you show in more detail how you set up your phone camera and tripod.

[@GNX157]

Your lighting is better here than in the other similar video on YT. Your major mistake was taking that spring off the plastic right away (it should be removed later from the metal part, and left on the plastic housing) and fully removing the pin and having the guts spill out. That helps no one understand what’s going on. You should of done like the other video, and gradually pulled the pin down, while sliding out each piece individually as it sits in the stack.

[@scarvazquez]

Amazing!! thank u!!

[@iffy_too4289]

WOW, This is insanely complex. So glad MTB is simple. Beautiful engineering though.

[@markifi]

mine has 50 thousand+ kilometres on it and only now starting to develop problems, so must be really well made stuff unless i'm just lucky with it (i have the last 10 speed version that still has the shifter cable coming out on the side, i think it might be 6600 but not so sure)

[@play4funornot848]

Does anybody know where I can find the fixing nut for inner mechanism from 7:32, or the bolt with the nut, or the Shimano code for it?

[@trekkeruss]

I am certain this answer is too late for you, but Shimano does not recommend complete disassembly of the STI unit, and does not offer parts for them. The only way to get parts would be to salvage them from other shifters.

[@rodrigraced]

Alguien conoce el nombre del sistema interno que se trabó

[@ivanteo1973]

the electrical contacts on the PCB should not be greased.

[@ivanteo1973]

@@altern8tive That's incorrect, grease (as used in bicycle) is non conductive and act as insulation. this is why you will never see grease being apply to electronics.

[@iffy_too4289]

So do you use something like Deoxit to clean and assemble the contacts dry?

[@dolinec]

You right, but do you think that he will ever use it with the Flightdeck computer? I don’t think so ;)

[@markfisher7962]

Wow! I can see why they're expensive!

kind of puts the whole electric shifting thing into perspective. a servo motor with a wireless button seems less complex than this.
