Square Taper Bottom Bracket To GXP Bottom Bracket Replacement 

I want to see how to remove it please

@@oscarpetrus666 Just watch how it is installed. Then do the opposite.

Thank u.

+Pak Nagasing I agree. Too many of these YT videos have poor acoustics. Can't hear half of what they're saying or droning. RJ does a very nice job.

Yup, he is good!

+christopher shara Do you have a reason to believe the BB shell needs faced? Was there damage to it?

No. I watched a video that said whenever retrofitting from a cartridge (JIS) type BB that the BB needs to be faced.

I have a threaded English 68 mm. I don't see the purpose of facing a threaded BB. If the cups thread in, then they would be installed properly (90°)

Yeah, a lot of stuff says face the BB shell. The tool expensive, and even my local bike shop said it really didn't need to be done unless there was some sort of damage or reason why they wouldn't be flat.

Thank you for your professional advice. I watched a 28 minute bottom bracket tutorial "Bicycle Bottom Bracket & Crankset Types Compatibility Identification Spec. Guide." Excellent, excellent info !! 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.

+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.

+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.

Maximillian Chong What happened? Cat got your tongue?

@@RJTheBikeGuy Thank you! I wish I had found this video before. Or, much rather, that the manufacturer would take as much care about their instructions as do RU-vid enthusiasts. Your generousity in sharing your detailed knowledge is invalubale for people like me (novis cyclist). Best wishes!

This based on SRAM's instructions: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-D1UHtUt_V2Q.html

I own several nice clickers. But I prefer beam torque wrenches for bikes. I like them better for lower torques.

Not even sure it is possible, unless there is some sort of adapter.

Brian Anderson You shouldn't use torque wrenches for removing stuff.

The bearings are larger and farther apart. Less crank flex. They are also lighter.

Because right hand threaded cups on the drive side can work loose with pedaling. Still, older French and Italian made bikes have them.

@@RJTheBikeGuy got it, just didn't remember where I saw it.

Shrug. Find the correct tool.

Yeah, biking is expensive once you get more serious into it, tools, parts etc... :)

@@RJTheBikeGuy That looks like it.

@@jeffbarish9105 You can install a cartridge bottom bracket if you want. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1BrVjDFqotE.html

@@RJTheBikeGuy Wish I would have seen this before, would have been a help. I watched the video you did on converting the shifters on the Trek 1000, was thinking about giving that a try. I have many miles on this bike, I have owned it since 95. Last month alone 435 miles and this month, I am at 288 miles. It has been a great bike. I will watch the cartridge bottom bracket. Thanks!

The limit screws on the front derailleur will limit how far the shifter will shift. You can use a triple shifter with a double, and will work fine. I did eventually replace the FD. Maybe a couple times I can't remember. At least once when I went to a compact crankset.

+Swansen03 ok, figured it out. Hollowtech II external BB fit euro, but spanish bmx bearings will fit the cups and are 19mm ID. ssoo, if anyone has any only howitzer ISIS BBs(long spindles) laying around, cut the spindle out and use this! i used a similar method, but www.biketrial.si/shop/product_info.php?manufacturers_id=14&products_id=286 Profile use to make something similar. basically, just a 128mm spindle with hollowtech II cups and spanish bearings, good to go! www.pinkbike.com/u/philly-bnb/blog/Spanish-in-Euro.html bmxmuseum.com/forums/viewtopic.php?id=204071

+Paul Jones Not really, because the chain line is about the same.

+RJ The Bike Guy Sweet! thanks for the quick reply!

Almost certain you need a specific frame for BB 30 as they're press fit check on the gmbn video about them but I don't think they can be made cross compatible

on my bike i cant take off the crank with no gears on it, i cant figure out a way to pull it off help mE!

Hi RJ I like the reviews on how to remove and replace bottom crank wheel drive and how to remove and replace the BB on all different types of BB thank you and you explain it very well and I have subscribed to your RU-vid channel thanks from Mark from the UK England

I doubt you can judge torque visually. Hard to say. You want them tight, but if you go too hard you can strip the threads. Not tighten enough, and the parts can come loose.

Most bottom brackets will be fine without facing. Facing just makes sure the two faces are parallel.

Newer cranks. Lighter. Bearings are farther out so less flex in the cranks.

Not really.

Thanks, once I get my Hollotech II BB, I plan to first use my hand to tighten as hard as I can before use the tool. Then I believe one quarter turn with Shimano Hollowtech II 2 Wrench Crankset will be sufficient.

It all fits and works. The spindle is in both bearings/cups. Take it apart and examine it and figure it out.

Not really. I use marine grease for pretty much anything involving bearings.

+Darryl Nuncio Sorry, but you need to do you own research and find what your needs and budget.

No, a UN26 usually has a plastic cup on the non drive side. Maybe a UN55.

If you have a French made Peugeot with a right hand threaded fixed cup, your options are limited. No GXP for you. You will have to find a French threaded BB or possibly a threadless BB. But I think you will be limited to square taper.

maybe I could re thread the frame?

Not that I am aware of.

I answered your other comment.
