Shimano GRX 810 Front Derailleur Fitting Guide

[@packratty]

I used this to completely adjust the front derailleur after installing smaller chainrings to suit my wimpy legs. When I saw unfamiliar features I knew I needed KZbin, having done that many times for many things, but I have to say that this is one of the best instructional videos I've ever seen.

[@KC-gy1vq]

Shout out to my local bike shop for giving it their best guess as to how to set up a front derailleur. This video is exactly what I needed to fix the disaster I was sent home with, thank you.

[@thecappy]

Haha me too. Shimano went nuts with these screws. I was surprised I had the plate on the frame. My lbs is an old man in his 80s and his young grandson. I'll have to show him this video.

[@pauljones4960]

I AM a local bike shop, got one of these in that the customer has played with. I am finding out wtf is going on before I get my hammer and blowtorch to it. I mean allen keys of course, allen wrenches to you in the States.

[@tomalexander9140]

This video is gold, went from 3 hours of frustration to getting it dialed in straight away after this, Bravo!!!

[@adrianz8222]

Greetings from Germany. After wasting serveral hours with other tutorials, you made my day! Thanks a lot

[@robertmela4132]

One of the clearest, most complete, understandable how-to fideos I've ever seen. Thank You! You've saved me so much time and angst!

[@stuartbyrne8255]

Jeez - did I ever need this video ! Thanks, turned a frustrating task into something quite logical and straightforward (bit a bit over complicated Shimano !)

[@DRamirezBr]

Wow, amazing video! I bought my bike in an official Cube store. The front derailleur was a mess. I took it to a local repair shop and it wasn’t much better. Thanks to your video I could fix all problems myself 🎉

[@junglejay77]

Great video! Thank you for taking the time to make such a helpful and easy to follow guide. There is nothing like seeing someone doing it - and your attention to detail was much appreciated.

[@jaspreetsidhu5708]

my bike shop didn't even do any of this, have had nothing but issues with my grx front mech, constantly catching, dropping chains, ripping through cables. Thank-you so much.

[@nigelperry9988]

Your "how to" guides are simply superb! Absolute lifesaver

[@garethhorn9274]

Thank you! You have saved my sanity! I'd been following the Shimano fitting guide for this derailleur and could not make it work - 20 mins spent watching your video and it's shifting a treat. Great guide 🙏

[@ivanradu]

Just wanted to say a big thank you for your amazing job, old school and you nailed it. Your experience and knowledge are incredible, and I've learned so much from you. Really appreciate you shared this video with us!!!

[@timoboyle8867]

A year or so later I need this video again, and wow! So thorough! Just perfect! So glad that it is available!

[@edwinkhagen]

Thank you! this helped me after I stretched my derailer cable and no shops were open. Got me back on the bike! Only detailed GRX 800 detailed video I could find. Appreciate!

[@Sworkspeed]

Your videos have helped me on so many levels. You probably hear this a lot, but thank you for taking the time to do this.

[@westonpoling1469]

Huge help. Been having loads of trouble with my front derailleur. I didn’t know shifting this smoothly was possible. Thanks for the video! Saving it for when I’ll need to revisit.

[@frogslips]

That is great. I have got that derailleur on a new to me bike and had no idea how to set it up, it’s very different to others on other bikes. Thank you.

[@PROstacky]

Great video, you explained every detail that is needed to get the front running smoothly, thanks!

[@jonathanfox7943]

I just install my GRX 810 by following this video. Nice clear instructions I watched it a couple of times and then followed several steps in one go. Worth noting that a cable pulling tool really helps getting the cable taught, and the cable pinch bolt needs to be screwed down quite hard, as the cable slipped through after I had installed the change and was tweaking the gears - so I had to restart.

[@affenmorchel]

Hi this is Mat from Germany...Thank you so much for this video. It helped me to refit my derailleur and saved my weekendride. Your the neighbour I'd like to have!!! Perfect explanation! If you lived near me, I would bring a cold beer straightaway...Kind regards!!!

[@FreeToCycle]

Glad the video helped you out!!

[@michaelsteven1090]

Saved my sanity!..I've tweaked a lot of FD's in my day but I had fits with this one..Thanks..subbed

[@corvus400]

So many adjustment screws! I like that you can adjust tension on the cable with a screw. Quite easy to install

[@dylancamacho]

This was so perfect. I stared at the service manual for so long not understanding what all the shift lever positions and such meant. This made it all so simple

[@shannonparker7404]

Thank you! I've been battling for an hour with my GRX front derailleur for an hour. This helped a great deal.

[@thetinusnl8834]

Here's thanks from another (still learning) home-mechanic. Heard a loud snap when shifting from small to big chainring, thought my cable was broken. Shifter and outer cables looked fine which was weird, but no tension on the cable. Seems like cable tension was slowly decreasing the past 2 years, fixed it completely with just this video.

[@tekrtu]

This is very clear step by step video about how to get Shimano GRX front derailleur adjusted, if you have one. My derailleur was adjusted so so, it bothered me a lot and made me hating the gears in the whole. While I had to change cable I decided to adjust derailleur again with this video. Success was quaranteed!

[@lisaclark7749]

Thanks

[@jasekjaan]

You literally saved my life. I love you guys!

[@RyanRKJ]

Thanks, helpful. These are a little different than the stuff I am used to from 15 years ago.

[@tobishua]

It's an awesome video guide, and it helped me to adjust the front derailleur on my bike. I've tried to adjust the front derailleur a few days, but after I've watched this video, the adjustment took only a few minutes! Many thanks!

[@Doc_Tez]

I have been struggling with this for so long. Thank you so much!!!

[@bicboi2883]

Your videos allowed me to adjust both my front and rear derailleur. My LBS couldn’t even do it. Thank you!

[@bobdylan6237]

Super helpful, was having a complete nightmare trying to figure this out. Thanks so much.

[@jrajan007]

Videos are great and super helpful. This is my go to channel when I need to adjust derailleurs

[@lisaclark7749]

Absolutely amazing video to teach me how to sort my derailleur from scratch. I’m a total newbie and this video got me sorted. So we’ll explained. A huge thank you!

[@BadTanLines]

duuuuuuuuuuuude thank you so much for explaining how to install that stupid little cable clip thingy around 8:15... that thing came loose on a ride today and FOR THE LIFE OF ME I could not figure out how it should go back on! Cheers mate, thank you so much!

[@futhyones]

Very good video, saved me so many troubles from a poorly fitted groupset!

[@stefang4706]

Hey I just wanted to say thank you very much! I am building my first bike from a frameset and also my very first 2x I was struggling till I found your Video

[@Mjtbikes]

Thank for for the GRX810 videos! They helped so much!!

[@nadiakamal8256]

Now this was a really fantastic video on how to install and adjust the derailleur! Thank you! I was alreay pretty desperate.

[@tubesockets120v]

Excellent video 📸 that is chaulked full of pro level mechanic tips.

[@rodrigovictorio7013]

Thank so much for this video 🙂🙂 very clear even for beginners

[@nicobergstrom]

Thank you very much! First time for me working with GRX 810 of my new Grizl. This was really really helpful!

[@TheMoonigans]

Great video. Thanks! The cable tension adjustment is by far the single best addition to Shimano front mechs. The Ultegra 6800 was an absolute nightmare to get right. Either too much tension or not enough.

[@AlexanderRoos-ut6qq]

So true, i was so glad when I discoverd my canyon just had an adjustment screw in the shifting cable...

[@SuperOlds88]

Nice relaxed and informative video. I hate the fact that Shimano has to keep changing and changing, my other bikes are so simple to adjust. Thanks for a great video.

[@robertpauly5442]

Superb video - very clear. I'm very new to this and yours is the best video I've found! Many thanks from Canada!

[@lylebilski5345]

Wonderful video! Thanks for helping me fine tune my new bike’s GRX derailleurs.

[@colinsharp630]

Well made. I just followed the steps and got out of a mess. Thanks.

[@ElCid_86]

Thanks. I just got mine installed and adjusted thanks to you and Sick Biker. You guys rock.

[@romneyphillips904]

Excellent video. My Revolt derailleur was so far out of proper setup.

[@matthewisherwood7517]

Phenomenal performance sir. Thanks for the help! Cheers!

[@rasmus9311]

Great video! Easy step by step guide to perfection

[@DPANDALEE]

Thank you so much for this video, concise and easy to follow. Most importantly each step is spot on.👍👍👍

[@davidsmethurst4318]

Thanks, that was just the ticket. I fitted grx 600 rings to my 810 chainset for a little lower gears and had to drop the front mech a little and reset. I'vr had a lifetime of experience in bike setup with campag, suntour, shimano, simplex, blah blah. This showed me how much I didn't know about modern tech, excellent front mech tensioning, double trim settings which I've only seem on a triple before. So please to have gone with GRX and to have it's modern features so clearly explained by a pro. BTW if anyone contemplates the 600 46/30 rings on an 810 spider the anti chain jam pin on the 600 rings is longer than the 800 as yhe 600 cranks have a hollow inside face. A few seconds with a file shortens it and avoids distorting the big ring against the drive side crank.

[@JonSauter]

Hey you helped me resolve my chain rub issue, thanks!

[@paulhatanaka8584]

Excellent video. Thanks for posting. Very clear and really helped me sort out some adjustment issues and now all is good.

[@benmartin1216]

amazingly clear explanation - thanks for this!

[@patrick1978maas]

Very good explaining of the screws and setup. I've been fiddling with my GRX front of the new Grizl. Gonna try your setup method this afternoon.

[@richard.berardi]

THANKS! Purchased a Trek Checkpoint ALR 5 new, front derailleur wouldn't shift up. They "fixed" it when I went in for my fitting. Still wouldn't shift to the big chain ring. Brought it to a different bike shop - same deal. This video and 20 minutes took care of it!

[@TheFlyingMonkey200]

amazing video! fixing all my drive train noise

[@Gtek22]

Great video very helpful my GRX front derailleur was not setup right after the lbs changed from my fsa to GRX crankset followed your instructions now it's all sorted 👍🏾

[@r.williams8349]

Thank you for the video very helpful. The Shimano installation manual is pretty hard to read…

[@TomNylundSuomi]

Thanks! I was wondering why I couldn't get mine to work, great video

[@renezweers6352]

Thanks, very helpfull! Actually better than the shimano documentation.

[@johnnnewmex]

This was consistent with the the Shimano technical document... despite that I couldn't get my new GRX front derailleur to shift. And I have been working on bikes 30 years. Usually Shimano stuff is cake to work on.

[@RunBikeRun1]

Great instructional video! Thank you for posting! Love my GRX!

[@grongrod]

Thank you very much! Nice, practical and very clear.

[@murd3rotica88]

Awesome and clear instructions. Thanks for a great vid

[@SuperDodoe]

Thanks for this excellent instructional video

[@aaronsvedlow4706]

Super helpful. Thank you so much.

[@timoboyle8867]

Excellent instructions! Thank You!

[@zzhughesd]

Lovely clear videos. Still struggle like hell. I’m best with mechs from the 90s without trim. If I installed weekly be fine. It’s once every two years imposs remember process

[@japawe]

Fantastic video. Thank you very much!

[@JackChessa]

Excellent. FWIW I followed this with the GRX 410 front mechanical and it was all the same.

[@PeterMacca88]

Been wrestling for a while with a Badly setup GRX FD on a new Giant Revolt. After doing the steps in this video and I think most importantly getting the tension right by lining it up via the tension screw it’s working properly now.

[@davido.6407]

Amazing, keep going! Best regards from Switzerland

[@alanfrench52]

Thanks mate just doing this, so glad I watched your video

[@Bottomburbsburnbums]

Great help! Cable tension - I seem to be able to have a useful trim at the top, or the bottom, but not both at the same time…

[@malennachbruchzahlen]

This video helped me alot, thank you, awesome channel in general, keep it up!

[@vlasiskalokairinos]

Your sharp explanation was able to make me understand and sort a factory bike delivered where too much noise and difficulty was coming from the derailleur. But please anyone help! ? My brand new bike with same GRX when I am on disc No 2 front, does not change in the back with gear 1( largest in teeth sprocket or the furthest out).All other combinations are fine! I have tried with H and L before seeing the video and had no luck. All other details are great by following the steps and adjusting. Thank you

[@jpspeedko]

Thanks for the help!

[@zachmugen1978]

Fantastic video, thank you! Installed and working so perfectly.

[@FreeToCycle]

Glad it helped you with the install.

[@Reeezeful]

This video helped me out a lot. Got my Canyon Grail delivered ago and the derailleur setting was horrible.. Managed to get it a lot better thanks to your video! Some problems remain: Being on the large chainring I can't use sprockets 1-5 (1= the largest sprocket) which seems to be wrong? I guess I should at least be able to use the sprockets 3-11 while being on the large chainring.

[@florindiaconeasa6049]

Did you resolve this one?

[@Reeezeful]

@@florindiaconeasa6049 It got a bit better after some more work but its still not perfect. I can use the sprockets 4-11 on the large chainring. if i go to sprocket 3 i can hear the chain rubbing against the derailleur.

[@golaoi]

That's really clear. Thank you!

[@HTS888]

Thanks for making life simple ;)

[@philipgibbons9909]

When attaching the cable through the pinch bolt, what position should the barrel adjuster be in?

[@nortcrusader]

Thank you, did you have to put a ring/spacer between the frame/bearings and the chain set?

[@xhrrdg]

I have this on my gravel bike. Quite a lot went into adjustment apparently.

[@rmcc655]

This was great thank you so much

[@MicskiDK]

Thanks great detailed video. One question: When you adjust for the big chainring, will that not counterfeit the adjustment for the small chainring?

[@ad9898]

Great video!

[@alanw.4511]

Fantastic video! Thanks! Just subscribed.

[@davesmeaton4137]

Amazing, thank you!

[@ryanhayes1401]

Great video! I’m having a little trouble though, the screw that’s goes through and should push onto the frame... the derailleur is placed in a position so that when the screw goes through there is no frame to push on, it’s just in mid air. This is an issue because I need to straighten the cage because the chain is rubbing the metal side...

[@jinjatube]

Does the cable tensioner bolt on the GRX front derailleur have a different function to the inline barrel adjuster I have on the cable near the shifter? If so, what's the difference?

[@Joecycles]

This saved me a head ache

[@josipX]

Thank you! This literally saved me during a ride in the middle of nowhere today. I have a question, the 2mm screw that goes through the middle, that is supposed to touch the frame is nowhere near the frame in my case (Giant Revolt carbon frame). It misses it by a whole centimeter. What should I do? Maybe put in a spacer in that covers this empty space so that the screw can touch that spacer?

[@realcneale]

Have the hi/lo limiters on the front mech changed? You never used to be able to use the hi limiter to actually move the derailleur outboard when the mech was on the large ring. Is this a valid way to adjust the position on outer ring? I used to have to use tension which was a PITA.

[@dickwarneke3225]

Great video, thanks!

[@paveldog9313]

Thanks as I have managed to get close to a decent setup but I have an observation that maybe you could help with? With the cable tension screw fully home the marks at the back are still not quite perfectly lined up. The screw was properly backed all the way out when starting.

[@FreeToCycle]

Not enough tension when the cable was clamped under the pinch bolt!

[@paveldog9313]

@@FreeToCycle Thanks for the reply. I'll go back to that stage but I was pulling on it fairly hard. Must try harder as my school reports used to say!
