As a bike mechanic i can approve of this method 😂👍

[@paradox963]

Wow, that is really the hard way to do that, don't flip the bike upside down, keep it right side up, set the drive side crank at 3 o'clock put your 8 mm and breaker bar in, so it's at about 2 o'clock, put one foot on the pedal and crank back on the bar, easy as pie. As a working shop mechanic, I only do this about 5 times a day. LOL

[@janbarrettnielsen2559]

It works....dang....! I just did this on my my new bike with Sram crank which refused to budge even with the aid of a cheap chinese impact wrench (I know I'm not supposed to use power tools on stuff like this, but I was desperate because the LORT - shit in danish - was STUCK). Thank you Mister "I do this 5 times a day". ❤

[@JaredRMorgan]

If I only helped one person with my video, then my work is worth it!

[@philipcarson8438]

Helpful to know which way to turn and that it can be very stiff. AN IMPROVEMENT: keep the bike upright with left pedal in forward position resting on a cinder block. This will brace the pedal. Position your Allen key and breaker bar also facing forward and slightly upward and push with your foot. The pedal is braced and your pressure keeps it on the ground. Presto!

[@JaredRMorgan]

I don’t have a cinder block but later on I did try this using an old bedside table thing and it did the same thing. Worked great! Just chewed up the table pretty bad. 😂😂😂

[@That.Guy.]

Or just use an impact gun

[@skp1970]

Great method! I was having so much trouble. Got it first time using this method. Thanks champion!

[@JaredRMorgan]

no problem! I know it's a bit chaotic, but it WORKS.

[@turtle_fiesta5965]

Put a strap around the opposite crank arm and chainstay. It will hold the arms in place and you can use all your strength on removing the bolt. Also works for stubborn pedal removal

[@JaredRMorgan]

I agree that this would work perfectly I’m just very nervous about putting a strap around a carbon chain stay maybe I’m overthinking it.

[@dadlife8289]

Instructions unclear, my cranks stripped

[@JaredRMorgan]

Time to call SRAM!! 😂

[@jojogat]

I replaced my nx cranks before and after so many attempts on loosening the bolt, i knelt on the breaker bar and used my body weight and tried tightening the bolt a bit more just to get it moving. After it moved i tried to loosen it using again my body weight with the knee. Oddly enough it was a success.

[@JaredRMorgan]

That’s interesting!

[@hjeffwallace]

I usually align the tool handle near the same side crank, so that I can pull it, sort of like squeezing handles of pliers. Usually just a regular Allen wrench will do.

[@samhenderson7528]

A traditional Allen key shouldn’t work… it’s supposed to be tightened to 54nm, which would bend/snap something like the park tool p-handle Allen

[@JaredRMorgan]

Sam knows^

[@michaelbennett8509]

I find that its alot easier if you remove the screw cap 1st, then crack the bolt loose, then reinstall the cap and unscrew the bolt to remove the crank That way you can do it with a ratchet rather than needing a breaker bar

[@JaredRMorgan]

This is the first bit of advice that I think actually makes sense, and totally worth a try! It's mental how tight these get!!

[@michaelbennett8509]

@@JaredRMorgan i work on cars so I'm use to really tight nuts and bolts lol. I did have abit of a nightmare trying to figure out the best way to remove the crank though. I was scared of damaging it with it being an aluminium alloy so i didn't dare use a breaker bar. It was the 1st dub crank i had came across and the reverse thread on the cap also made it a little confusing lol. Now though i can remove it in seconds with just a ratchet.

[@peterrose1695]

The best way I found is to take the rear wheel out and unbolt the derailleur, then position the drive side crank pointing up and towards the front and then putting an allen key in where its positioned under the crank arm while in the bolt. Then setting the bike up right on the ground with the allen key resting on the ground and just using your foot to stomp on the pedal and itll break the bolt loose.

[@JaredRMorgan]

man I need a video! I can't envision this.

[@mrhaggin429]

Shimano's new HollowTech BB is the only way forward. Just engineering brilliance!

[@JaredRMorgan]

They got a new one? I gotta check that out!

[@th0m]

A direct drive trainer makes this job a piece of cake for anyone out there suffering

[@JaredRMorgan]

thats an interesting tip!

[@jamesthornton1486]

You should use copper grease to stop them from being so hard to undo

[@JaredRMorgan]

I’ve heard the anti seize can help yes. My long terms solution has been shimano cranks. 😜

[@TheyForcedMyHandLE]

Slip a pipe over a crank or zip tie a length of something to one of the cranks for more leverage and better control.

[@JaredRMorgan]

Agree that's a good idea. Eventually, I'll find something I can slide over the other crank arm that I can have faith in that won't slip or fail. It takes a TON of force!

[@samj1185]

watched, understood and thought about it for a second. Then: inserted allen wrench w/ approx 30 degree angle between allen arm and crank arm, leaving enough clearance for long allen arm to clear crank arm when it moves...used 1/4" rope and wove 2 strands snug around allen arm and crank arm being sure to wind around pedal shaft to prevent slippage. tied ends. inserted 5" rod(short enough to clear acute angle of key and crank) and began twisting tourniquet style. it gets tight quick and had to use small pipe to finish but it popped loose , no fuss, no rage.

[@JaredRMorgan]

Make a video. You description is hard to follow.

[@samj1185]

@@JaredRMorgan yeah, hard to describe but easy once you see it. a vid is a good idea. will send a link.

[@Gbark713]

Better: with the bike on the ground upright, remove the drive side pedal, put a 2’ or longer piece of PVC pipe (standard 3” household diameter) on your crank arm pointing backward, resting on the ground (7 o’clock), use a handlebar or pipe or whatever on your 8mm Allen wrench and insert it in the bolt angled forward (3 o’clock), weight the saddle with your chest, wrench upward, get it done in one go, with much less effort. It worked so well for me after I couldn’t loosen mine with the method above that I had to comment. I had a six foot length of 3” diam PVC pipe handy though.

[@JaredRMorgan]

I don’t have that much pipe to my disposal sadly. But the good news is, there isn’t a set of SRAM cranks in my house anymore. 😁

[@thetruelefty9302]

Tie opposite crank arm to the chainstay. A large velcro strap works as well.

[@JaredRMorgan]

I've tried strap methods before and had them violently pop off. Scary proposition when dealing with a carbon frame. Not saying it wouldn't work, but I prefer to have full control of the situation rather than relying on an inanimate object.

[@thetruelefty9302]

I have been a mechanic for 37yr. Your not using a large enough strap if it pops off. If using velcro should it should be about 2 inches wide and about a foot long. Also a 2 foot long piece of 2 inch pvc pipe with a slot cut in it to fit over the peddle axle. In the end game it's what ever you are comfortable with. As long as it works too get the job done. Work smarter not harder.

[@fuckgoogle7314]

I like to let the other pedal press against my hip so I can both hands on the rachet.

[@JaredRMorgan]

Smart!!

[@MasterOfAnarchy]

I Do it the same way 😁👍🏻

[@wasimraja7439]

Could you use an impact wrench?

[@JaredRMorgan]

Tried it to no avail.

[@l00tur]

You can, just need enough breaking power. I have a Milwaukee M18 Fuel for my car stuff, it made short work of this on my SC Chameleon

[@Khalidazizphoto]

When you have a hydraulic brake, make sure to give it a few pumps after you put it back from the upside down position.

[@JaredRMorgan]

I normally do just out of habit

[@mikuramsay]

No? That just means your brakes have air in them. And would require an air bleed.

[@mpvabi95]

@@mikuramsay every brake has air inside it is not possible to bleed it 100%! Normally you put a spacer in the caliper to bleed so in the moment you pump the pads onto the disc there is room for air inside the system what is normal! You can bleed the brake without the distance piece but then you overfill it and when you push back the pistons you will destroy your lever in 90% of the case because the Oil/Dot can't go enywhere. That is the reason of the reservoir in the lever.

[@mikuramsay]

@@mpvabi95 no, after a clean bleed, no air should be in the system, if it's airtight, the pistons being pushed out will create a vacuum, not an air pocket, there's a reason why hydraulic brake levers will have a rubber diaghram in the resovoir instead of just being a solid piece. It's only when you open it up again, where air gets in and you can fill it up with more oil. However, air can also get in over a long period of time, so it will have to be bled when the time comes as well. under no circumstances should your levers go limp when you flip your bike, it means it can happen out on the trail as well.

Nice! My impact can’t do it.

[@circuitfever]

Instead of pulling on the breaker bar, push on it. Much easier.

[@JaredRMorgan]

I’m concurrently pushing on the crank arm. Pushing is easier than pulling and that’s why I choose to push on the shorter of the 2 levers. Creates equal pressure.

[@wiciekus]

i'm using impact wrench

[@JaredRMorgan]

My 20v dewalt brushless doesn’t stand a chance against Sram.

[@Ox111BA6FA]

why pull the bar instead of push using your weight?

[@JaredRMorgan]

I’m pushing too. Pushing is easier so I do that on the shorter lever. Makes the forces equal-ish so the cranks don’t spin.

[@TheDarkElk]

I needed a like 4 foot Cheater bar lmao, sram really likes em tight

[@JaredRMorgan]

its ridiculous! LOL.

[@peterrose1695]

Its not really all that tight. The way they make the threads just cause them suckers to seize. From the friction of the bolt threads along with the pressure on the extractor plate makes em pretty nasty. Wear gloves too, itll help with the break away shock to your hands. Its like hitting a metal pole with a aluminum bat with no wrap on it. Hurts like hell.

[@crf80fdarkdays]

​@@peterrose1695 not even that bad

[@someflipswhoguy]

instead of leverage up, push down so you have better weight behind it

[@JaredRMorgan]

since pushing down is easier, I do that to the shorter side (the crank arm)....it levels the playing field keeping the crank from spinning.

[@someflipswhoguy]

@@JaredRMorgan ah yeah it’s reverse for me, pushing up the crank and down the tool

[@Timtimzi]

Just curious. Anyone has the links to Amazon where I can grab the items? I always find it hard to find the correct bit sizes and attachments to the breaker bar

tried it...the force would normally just push my leg up or make the bike topple over. This is the way.

[@slimsqde7397]

i feel like it would be easier to grab the other crank so you just pushing down, not down on the crank and up on the bar, you use your body weight rather than muscles

[@JaredRMorgan]

You would think but I’ve tried every version to find what’s easiest and somehow this is what’s best for me. I’m using all of my body weight to keep that crank arm stable while pulling. Since it’s all on bearings it wants to spin.

[@yonglingng5640]

​@@malicioussteev Self-extracting cranksets have the bolt that installs the crankarm to the spindle held captive by a left-hand threaded cover that the bolt butts against when you turn the crankarm bolt anti-clockwise to remove the crankarm from the spindle. If that cover is missing, you're not getting the crankarm out. In this video, the cover we're talking about is the ring in the center with two DUB logos on it, usually installed with a pin spanner, 10 mm hex tool or cassette tool, depending on the model and brand.

@@l00tur maybe stop being so arogant when you have no clue what you are talkung about. Modern braking systems are "open systems" (google it 5head). At your lever is a resavoir for your mineral oil or dot-fluid. When the pistons at your caliper move in with the weardown of the pads, fluid will run after to compansate. Air has to get inside the resorvoir otherwise the liquid wouldnt be able to run after caused by negativ pressure. Now if you turn your bike upside down without the levers pushed, the system is open and air get into the hose. When the lever is pushed the system is closed otherwise you wpuldnt be able to build up pessure.
