How To Install & Set Up A New Mountain Bike Transmission

[@gmbntech]

Let us know what other mechanical How-To videos you need in your life! 🛠

[@sandy_knight]

How about a How To on flat grinding sockets. I know you can buy chamferless sockets from various places (Park, Abbey etc) but nobody seems to sell a 20mm socket for 2017 Manitou Circus Experts. Should I just bodge it with a normal socket or is there a better way? On a side-note, when bending a spoke into a trail-side chain 3rd hand tool I always leave one side long. It makes it a bit easier to remove with wet/cold hands and harder to loose. It also comes in useful for a shed load of things, off the top of my head, you have a pick for cleaning out muddy bolt holes before you try and round them off ;-) you could unbend it and use it to fish out ghetto EDC items from your handlebars/BB axle, maybe even holding a tourniquet tight! (hope you never have to use that one)

[@Jacob99174]

Selecting and installing a complete headset

[@sandy_knight]

@@Jacob99174 I second that if it includes removing the old headset. Do I need the Park RT-1 and the RT-2 to remove a tapered headset?

[@zebulundocallas]

I did not know you can align your derraileur like that.

[@bugboy152000]

#GMBNTech @doddstar1979 Could you do a bit on how to get the correct settings on a fork and shock? I know you have covered TONS of material on them in shop. But I would like to see one trail side on what to look for. I remember one you did in Spain with fork rebound. I'm certainly capable of making the adjustments but not necessarily good at knowing what I'm feeling on the trail. Some tips on different things to look/feel for while riding would close the loop for many on getting the right suspension set up.

[@brokkoli27]

For setting up B-tension: Shimano 12 speed derailleurs have a mark on the back side of the cage which you can line up with the biggest sprocket on the cassette!

[@willienillie6337]

thanks for that tip. plan to upgrade my 2x10 to 1x12.

[@YaddaYaddaDa]

I am now building my second bike on my own thanks to you guys and these videos. Thank you!

[@KarlDonovan]

Okay, so after Halfords well and truly stuffed my bike I had a problem. Gears were clunky front derailleur hardly worked, frame scratched. Appreciate it is a Carrera and my first bike in a long old time, but still, not cheap and rendered useless by them. However not being one to throw the towel in just yet, I tooled up, stripped bike, took all the crappy components off, repaired paint work. Going with a reasonable single front cog Cues 11 speed U6000 kit, with no idea on what to do or how to do it. This video is probably the best and had my bike up and running in an hour, took it for a ride and fantastic! Love it again and it is transformed. Just wish I had viewed a few videos before buying my bike and may as well have spent a lot more in the first instance rather than throwing good money after bad. However! This video is fantastic, clear and concise (there is a lot of crap on you tube with people being more about themselves than what "you" want to achieve). So keep up the excellent work, I am a convert!

[@michaelmoore4369]

Thanks for de-mystifying this process with a simple, straightforward demo!

[@kjmh67]

Great video Doddy. Learn something new every day 🤣 Easy to understand and follow

[@Pienimusta]

Life without carbon feels so much easier. Great tutorial!

[@GHinWI]

Needs whole video on crank sizing (width and spindle diameter) and spacer placement, BB and crank. Also measuring chain line.

[@CarkeekW]

The Hanger alignment tool is way underrated and imo needed for every bike, the first thing i do on a new bike is use the hanger alignment tool and Every Single One is out, I offer to do my mates bikes now I know that and tell them i have never found an aligned hanger, and guess what, theirs is out just like all the rest. Id rather have a GX aligned than XO1 that is out and the tool is very cheap compared to its Upgrade benefit imo.

[@fatbikemontage2931]

Excellent comment, I have found the same. Solves a lot of shifting issues too. Its the first thing I do both on new bikes, but also before I adjust shifting tension.

[@VictorLebredo]

Great video, thank you! Very well explained! Just bought the Gen 3 Procaliber 9.5 and I am upgrading to Shimano XT. I work on my boat outboard and truck but never on a mountain bike. The complete group set that I am taking off from the procaliber I will be installing it on a 2019 Rockhopper 1X. I will be looking at your chain video next! Thank you very much!

[@jb2cool_mtb]

I always like these real-time videos, that way you can practically follow on at home monkey-see monkey-do style. I wouldn’t mind seeing a video on beating replacement for a full sus bike, ideally one there the bearings are pressed into the frame so you need to use a blind bearing puller or a slide hammer to get the old ones out.

[@michaelgunawan2319]

real-lime

[@richardbridges7664]

Good job Doddy

[@davew5583]

Yeah boy. Old school is old school :)

[@GHinWI]

BB press is more than just a “miniature headset press”. BB press has sized dies that fit into the opposite side of the BB, so that you’re guaranteed the cup you’re pressing is axially aligned. I’ve learned the hard way that no method other than a proper BB press is acceptable. Better to get it done in a bike shop if a person won’t get a bb press. I like the “wheels manufacturing” one.

[@KarlDonovan]

great video, am embarking on changing my group set and feel a bit more confident that I am going to manage it now :)

[@Travellingwbj]

Keen to see this bike out and riding, seen quite a few videos of it just parked up

[@fra93ilgrande]

Just got me a full XTR 9100 groupset, that's exactly the kind of video I needed, very helpful, thanks 💪🏻😎🔝

[@andrieslouw6588]

Doddy: "one of the bolts you probably won't check" Me: *Never checks any bolts

[@donsmith2833]

Perfect timing. I am awaiting my delivery of Deore 5100 groupset to upgrade my Talon 2 (international version with 2x8).

[@ejpeiker]

Even easier then the self-fashioned chain tool made of an old spoke, simply use a chain wear tool to hold the chain in place while you install the master link :)

[@kodikodi9948]

this is just the video i needed. i always wondered how to do this. thank you!

[@chenderson4969]

Awesome video mate. I enjoyed the attention to detail.

[@gmbntech]

Thanks for the support, @C Henderson! Glad you found the video useful!

[@jeremyparsons5379]

Great, very timely too 👍

[@TimMillernapavalleyfilmworks]

Master of his craft 🚲

[@gmbntech]

Agreed! 👍

[@thim8009]

Thanks Doddy, building a bike for 1st time and that's my next step.

[@gmbntech]

Thanks for the support, @Thim! Good luck with the rest of the build! 👍

[@trevw9958]

Hard tail looks nice

[@pughmtb9628]

Great vid doddy I will be upgrading my drivetrain in the next few months and will be referring back to this vid , I’d also like to see how to upgrade more budget type bikes converting 3x systems to 1x 👍🏻

[@thegrommechanic6265]

You should name these series! Cause I realized far into the vid that it was actually a tutorial and not a theorical vid.

[@johnnl]

According to the Shimano manual the derailler needs to be setup just right of the smallest sprocket, not in line. That’s my experience as well with the 1x12.

[@bobothericefarmer1878]

Perfect timing vid about to change my derailer

[@gmbntech]

Good Luck! Hopefully this helps you! 👍

[@thsaintful]

that is one beautiful bike!

[@MarioNhampossa]

Great job 😊

[@slick-riq]

*** WOW ***… I’ve generally been nervous to work on anything out of fear of messing something up. And other videos I’ve watched, because they’re not real time, they skip over subtle details that matter… I really really appreciate this, thank you so much! Yea I would love an endless series… and even manufacturer specific. Eg this is a good overall one, I’d totally be interested to see the exact same video but specific to SRAM Eagle…. Or one that used threaded bottom brackets… even the simple variations are helpful. Also appreciate knowing the exact make and model. Like which grease did you use. Thx!

[@s.irvingbeer1207]

excellent instruction

[@Jacob99174]

Excellent video!

[@gmbntech]

Thanks, Tim!

[@matthewvest2236]

Thank you for the info

[@ThunderStruckMTB]

As an AXS owner, I would already be done with my lunch and beer.

[@GokkunGuru]

Good one. Another AXS owner here. It rocks. Never going back to wired.

[@gmbntech]

AXS is such a great bit of kit! Imagine having to use cables! 😅

[@McCreadie88]

Doddy, why don't you use a torque wrench when you tighten the bolts? You mentioned about stripping the insert out of the crank arm without the use of the washer, this can still happen if you over torque due to the lack of a torque wrench

[@ecoeco86]

Hy Doddy, i have a little advice for you... The last 3 Sprockets of an 12 Speed Shimano casette have a little circle/dot groove on the outside of the teeth. so if you alining those 3 they will fit. ;)

[@mtb9299]

Nice VID ✌👍

[@timushijima2307]

What was the brand of chain guide that was installed? Most I've seen don't work with press fit BBs

[@joedatuknow]

Great video

[@baronvonrichthofen2021]

Great video! I’m just about to replace my drive train, and this video has some great tips to consider! I was wondering though, what spray lube do you use to lubricate the cables?

[@philso7872]

What types of lubricants do you recommend for injecting into the brake and shifter cable housings?

[@luisjusinojr6486]

Hey Doddy, I am currently performing a new bike build and was wondering if you recommend waxing the new chain before you complete this process?

[@gratver]

Sick. Bookmarked the video. I'm right at this point with my self build (commencal meta tr) What would you recommend using for the anti seizing compound with the BB? Since the frame is aluminium. Got all the other stuff figured out, just not the compound yet. This video came right on time though. ;)

[@martingru]

I really like that chain guide , where i can find it anybody knows? Thx in advance.

[@saulhernandez738]

What kind of chain guide is that?

[@pauldelarzac615]

My wheels came with a 2mm washer that looks like it fits on the driver body. What’s it for? Thx

[@yodapig]

Some hubs are designed to accept both MTB and Road cassettes - so depending on the cassette you're using you may or may not need it (for example a quick google says that with Hope Pro4 hubs you use the spacer for Shimano MTB cassettes including 10 or 11 speed, but that you'd leave it off if you're using their 11-speed road cassette) - the spacer goes on first, then the cassette.

[@captjak4386]

Can someone please tell me what brand is that chain guide and where can I get it? Cheers!😃

[@willienillie6337]

Does shimano make 12 speed cassette 51t that is not microspline?

[@Rossmann32]

On a carbon frame , is there a right and wrong way to mount a seat clamp ? ( I mean bolt to the back or front ? ) 🧐🧐🧐🧐🧐🧐🧐

[@liquidfluidity8061]

Is that a Park grease? I have been using their "green" but do have a carbon frame. Most of the orifices on the frame do have aluminum inserts though. Either way, I'd rather be safe than sorry ;)

[@ish474]

why do I watch videos on things I've done many times🤷🏻‍♂️🤷🏻‍♂️🤷🏻‍♂️

[@Swoxx]

What frame is this? It's gorgeous.

[@gmbntech]

It's the Orbea Alma! It's such an eye-catching XC hardtail! 😍

[@Swoxx]

@@gmbntech It really is! Thanks for letting me know 😀

[@abhigrg3804]

#AskGMBN I want to make a career in moutain engineer,so could you please tell the process and the thing I need ie qualification and studies I need for it.

[@phil_dubss8335]

#askGmbnTech Hi Doddy, I recently got a 2012-13 year model Nukeproof Scalp downhill bike. I’m considering swapping to a different fork like a formula Nero R or something else like that, but was wondering if I’d be able to run a 27.5 front end comfortably or if it might cause some problems further down the road. If you read this and are able to get back to me, then thank you very much it’s we’ll appreciated

[@MrStevegregory]

Surely it's insert not inZert.

[@norman-gregory]

Next time...Steel Frame (hardtail) with a threaded BB. Cheers. mmmm STANTON.

[@GokkunGuru]

Is that an Orbea Alma?

[@gmbntech]

It is indeed! 👍

[@8o8ertmtb]

Why no torque wrench.

[@shashiekka7917]

No issues with assembly for me kzbin.infoUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L but I could see where some might benefit from using an experienced bike assembler/mechanic. I'm an older rider starting back after a 10 year break. This bike exceeds my capabilities and has been easy to get comfortable riding. I'm mostly on easy trails with almost no street riding and have not been disappointed with the performance of the bike. My fitness level is far below what I previously rode with and because of that the mileage is going on the bike slowly. While I'm losing weight slowly, the bike seems to tolerate my 220 pounds just fine. The bike has been used by several family members ranging from 5'5" - 5'9".

[@yankeepalu8627]

Should do more videos on more cheaper bikes because we are not all rich.

[@nathanroccisano5592]

Press fit bb’s were a rubbish idea. Threaded forever.

[@davew5583]

Sorry , but no KNOW. You know, or should.

[@th_js]

I can not believe that you're doing this video again.

[@petrmatousek7422]

cant blame them, but its pretty obvious they recycle their content As I begun MTBing GMBN was priceless source of information. From time to time there is still something helpful but overall now I look for content elsewhere.

[@turtleman190]

@@petrmatousek7422 there is only only much content you can make on bike it was inevitable it would happen

[@th_js]

@@petrmatousek7422 Yeah, exactly same for me. Started out with me searching for info on how to fix brakes squealing, and found the video where Si was presenting. Watched GMBN happily for years and learned a lot, but sadly, there hasn't been basically any content that would've sparked my interest in quite a long time already, since I've already seen the numerous other versions they've made of the same topic. There have been some good videos, like the "Most custom E-bike ever?" or something along those lines on EMBN, and some stuff on Tech. Would be interested to know what the presenters and other crew think of this honestly but obviously we can't hear their real opinion..
