Square Taper Bottom Bracket To GXP Bottom Bracket Replacement
Тәжірибелік нұсқаулар және стиль
I show how to replace an older square taper bottom bracket with a modern SRAM Truvativ GXP (Giga X Pipe) bottom bracket. I also show how to remove and install the cranksets. This a cool upgrade/update to a vintage bike. This was part of my DIY cyclocross/gravel bike project.

Yup, he is good!
RJ The Bike Guy and the Park Tools tutorials are the best on KZread.
It's been so long since I've worked on bikes just seeing the loosening of the crank bolts really takes me back I think I used to open up every new or used bike I bought just to grease everything up Good times, just bought a bike again, looking forward to the weekend to set it up!
just discovered your video and find them really practical. especially when you do the work live rather than pre-do the task as some videos do. With your videos, like the fork removal one that i watched earlier,the viewer gets a true picture of what the task involves particularly with seized in parts thanks
I very rarely comment on videos, but in the midst of a bunch of confusing technical noise concerning BB's, this video made it super clear and easy to understand. Thank you so much!
Of all the bicycle channels I have found yours is the most helpful! THANK YOU!
Thanks first for showing that it's possible, and then for showing that it's actually not that complicated. Got the old riveted together steel square taper crankset and BB replaced on my MTB with a new Deore Hollowtech II BB. Took about 45 minutes start to finish, including hunting through my toolbox.
That was fantastic. That was a really helpful step-by-step guide. I really like my local bike shop and will use it for removing and pressing in my new headset but I wanted to try this bottom bracket myself. I have the exact same job, going from square taper to external. I'm sure this would cost double for what I spent on tools. Can't wait to try. Thank you for the guide as it gave me the confidence I needed.
Thank you. That's really clear instruction and this is exactly what I am trying to do with my bike, replacing the square taper BB with another BB for my new crankset.
I'll be upgrading my bike's drivetrain from a MTB gearing setup to either a 1x or 2-ring road type deal with an ultimate goal of installing a Quark (spyder) power meter. FWIW, bike has a 73mm BB shell. This and other related videos of yours will be a very helpful aid if I choose to buy the necessary tools and do the work myself. Thanks so much... feeling inspired!!
Love this! Thanks for all the videos! They really demystify working on your bike(s)!
Perfect tutorial. Thank you, Sir!
I’m about to convert my square bb to bb52 Shimano, but I’m still looking for few tools. Thanks for the video very helpful

RJ The Bike Guy Have a question for you. Bought a 2013 Masi Uno early Spring, I want to put a new bottom bracket and crankset on. Will a SRAM Omnium BB and crankset fit?
Nice chain set
Thanks!
I prefer sealed bottom brackets because I think they last longer and are much smoother. Also, make sure you put a sealed BB in the correct way round. I had an idiot moment recently where it I couldn't get a sealed BB to screw into a bike frame, I eventually realised I was trying to put it in the wrong way round. lol

+john smith Not only that but square taper cranks can take the abuse of everyday riding for people like messengers & food delivery people. You can go years before changing the cranks and bottom bracket whereas with most external bb's you'll be lucky if they last 6-9 months. Sram Omniums are known for their shitty bb's. Plus I've had friends get hurt because they are riding and one of the crankarms falls off with these types of cranksets. I'll gladly choose square taper over these any day.
@samanderson7745

+dapster Sounds like some shitty install on those external BB's if crankarms are falling off. I've been running BB30 on my road and triathlon bikes with GXP on my cross bike with no problems. My triathlon bike by itself has over 3,500 miles on it and I'm still running the same BB. I do prefer ceramic bearings over steel as they're less apt to warp, but friends have been running steel bearing BB30's and GXP's for thousands of miles with no issues. If you like square taper then stick with them, hopefully nobody is going to dog on you for it as every rider has their preferences, that's the beauty of this sport.

Sam Anderson GXP's, the exact type of BB that I am talking about. 3500 miles in what period of time? I do that in about 5 weeks, not 6 months as a courier. Plus no one has ever "dogged" me for using square taper. In fact, quite the opposite (you were right. Square taper lasts so much longer than what I've been using. Why didn't I just stay using ST? Oh that's right, looks.) As far as a shitty install it's far from it. Then explain to me why I've had the same crankset and BB since 2008 - installed by the same exact shop as most of the people I know who use Omniums - and yet it seems like every 3-4 months someone I know has had problem after problem with the GXP bottom brackets such as cracking, loosening, or failing. It's not the person installing it as much as it's the product themselves.

Is this "new" bracket system better that the one you replaced?? That removal tool is expensive!
In my case on a Boardman Sport, the drive side crank was removed clockwise and the left side anti clockwise. Also, definitely recommend heavy duty torque wrench to remove. Luckily I have a 60" Torque wrench - would not have got it off without it.

Would using an anti-seize compound like Permatex be equivalent to using bike specific grease on bike threaded fittings, such as BB retaining rings and bolts? Based on 25 years of working on cars anti-seize has been my go-to for thread treatment. Could it be that a bike isn't subject to the higher temperatures so the grease is fine, given the convenience of having it at hand? Or is there better performance (water resistance?) to the grease? And THANK YOU for the excellent videos! In the last few months I've jumped into working on my 12 year old MTB and found I really like it, with your excellent videos to guide me around the tricky stuff!
Great video. I know it’s kind of straightforward but here goes , What if I’m going to convert back to square taper from bb30. Any thing I should be worried about / know beforehand. B.B. shell measured 68mm Thanks in advance

Hi does the old BB have ceramic version ? Instead just want to get new crankset can I just upgraded the old BB ceramic version.?
Hello I have supercycle hooligan mountain bike with 18" frame. Could you tell me what size bottom bracket square taper I need. Thank you
Since you were using a cartridge BB, by converting to an external bearing kind, would the inherent chainline of the bike be altered? How do you fix this?
Hi.. some suggest that we need to get the shell faced before changing to external BB like GXP. any thought on this? I saw you just did it without facing. great video. thanks.

Most bottom brackets will be fine without facing. Facing just makes sure the two faces are parallel.
Hey I am trying to follow along with this hybrid to cyclocross build, but the videos are not numbered, have similar titles, or on a playlist together. How many videos are in this build? Could you organize them in a way to watch this bike be completed?

Is the gxp bottom bracket still useable without the dust cover and the middle part?

Not really. I use marine grease for pretty much anything involving bearings.
@rjthebikeguy Has anyone experianced rubbing between the BB cups & the crank on the drive side? It almost seems like there should a 1-2mm shim included.
Regarding the use of spacers: it depends on the installed crankset, frametype and the resulting chainline. For MTB cranksets like Shimano Deore XT or similar the optimal chainline is located further apart from the middle of the bike and therefore has to be adjusted with spacers if you have a bottom bracket that measures 68mm. For road type cranksets like 105 the ideal chainline is located nearer to the bikes middle plane. If your road bike frame has a 68mm bottom bracket you dont need to use spacers.

I love upgading old unique frames that are in good shape with newer technology. The guys at the bike shop like to look at me like I have 3 heads for dumping so much time and money into a frame worth $60. But if its a rare frame in good shape, why not ?? Facing, is that just for press fit cups ?

I'm between XTR FC M970 or FSA SL-K. The XTR's I believe are lighter. But I have SL-K bars and stem. Any suggestions ? Anni headed in the right direction ? I know it's kind of subjective. But you know more than I do.
Thanks! Great explanation! One question though any tips one can do to achieve the correct torque without the torque wrench ?

Newer cranks. Lighter. Bearings are farther out so less flex in the cranks.
I am upgrading a 1980s Motobecane with a square tape BB in a Sram GXP team English, but the drive side doesn't thread ni completely. It just threads in half way or less. The non-drive side goes in completely. Any suggestion?
i wish i could find it again. it was a sram mtb bottom bracket and there is a bmx bearing that fits perfectly for the OD of an ISIS spindle.. can't remember any of the specific off the top of my head, but, i'll have to dig it up
