How To Remove, Regrease And Replace Your Bottom Bracket | Mountain Bike Mechanics

Creaking bottom bracket? Here's our guide to solving it...

A noisy bottom bracket isn't just annoying; those gritty bearings could be slowing you down too. Luckily, this video will help you out. Start by stripping your bottom bracket down and thoroughly cleaning and regreasing the threads. If that doesn't help, it's time to replace your bottom bracket. Scott's got you covered with that too...

Don't forget to SHARE this one too!

Never seen one of those clutch mechs before (live under a rock)...what a time saver!

for Sram bottom brackets and cranks, I add a 24mm x 2mm rubber o-ring on the drive side since there's usually a space between the crank/chainring and bottom bracket on that side. It helps in keeping that side of the bottom bracket sealed.

here is a special wrench that is reverse threaded specially designed to prevent you from attempting to lube your crank.

Thanks for the video man! Mine has been creaking like crazy, happy ill be able to get her fixed up now without waitng on my LBS for a week.

[endurotruckererniedesjardins]

new cranks are so nice to work on compared to the crap we had before spline drive. I snapped and twisted so many bottom bracket spindles back then. more expensive they were the easier they snapped. one time I cut my leg on a xt so bad I should of went for stitches. love the new stuff so glad I sent back so many broken bbs for warranty lol

[AustinOutdoorsNorthWest]

Thanks for doing this one guys! I was one who requested this how to! I had already figured it out myself though and made my own tutorial on how to replace a truvativ power spline BB, a different style of bottom bracket! Cheers fellas! Austin, Seattle WA!

Gmbn you guys have helped me so much with my bike set up.
Fantastic hosts brilliant and accurate when it comes to set up and knowledge. love all the the videos and the dirt shed show

[rogerwoudman]

Excellent video and very helpful for someone who is not particularly good at the mechanical stuff!

[dennisneufeld]

Could you show us how to service Rockshox air sprung forks? These videos are great! Keep them coming.

[cameronroche]

Great video!! I was literally going to do this next weekend, cheers boys!

[jackthompson]

Please make a video on how to measure and decide which bottom bracket you need as all the different types and sizes can be confusing!

[TheChricke]

Couldn't you do videos on how to service forks and shocks?.. How to change seals/change oil/service internals etc... ? This is probably something people take to the LBS when problems, but in my case(and probably many others) there is no LBS that knows this stuff and it is too expensive to send to RockSHox/ FOx for service.

[traingp]

Don't forget to take the chain ring bolts off and clean and grease them because they can cause creaking noises from being dry.

[glynncairns]

Thanks for a useful video. one that springs to mine is how to service suspension fork lower legs

[joeygill]

would like to see a video on how to service your hubs.

[javierdavila]

Thank you so much, I have been breaking my brain figuring out how to extract that darn pedal off.

[renzoeltigre]

Something to remind is to also open your bottom bracket and check the bearings, remove the caps, spray some degreaser and regrease them, because those bearings are the ones that move when you pedal, the video is good but is not attacking the core of the problem.

[Metal-Possum]

GMBN has definitely improved over the years. Don't let Doddy and Henry see this one.

[DrgnWd]

Pretty neat and very good detail video

[IvanHausVonSpreitler]

Could we please get a video or review on power meters for mountain biking and proper ways on how to use them? Please? Love you long time. Thanks!
