I have no idea what specific BB standard my bike uses, but it has a 20+ year old Ti road frame with a threaded BB into which I installed a square taper sealed cartridge Campy BB that cost under $20 in 2003 and has been absolutely perfect and is still smooth as can be. I mostly ride on paved roads but occasionally ride over dirt, grass, gravel and roads that are in horrible condition. Works for me.

As a mechanic, good video! And your Fazit fits😁‼️ Pressfit isn't as bad, like a lot of people think. The first year of Pressfit, in my workshop, I hated this " plastic toy story" stuff! Since 2017 I use Shimano press fit, on my actual aluminum DH Frame, and I never had Saint cranks, running that smooth and easy. But for almost 80 to 90 % of all bike frames, BSA is the best and most proper way, solution. Clean Thread, tightening brackets, Crankshaft and cranks mounting. Ready to go. The only, a bit negative thing about Hollow tech II Shimano bearings, they have a bit less long life durability qualities.....

[@markdundon9922]

A brilliant video, as a home DIY mechanic I have spent many hours researching up the different BB standards over the years. This is a great summary thank you. I have Shimano BB89 ultegra version on my Canyon and surprisingly I got about 16,000km on it before the bearings went on the NDS cup. I've just replaced it with exactly the same BB. Very happy with that level of longevity and the cost is very good.

[@kylezick7345]

Worked in shops all through all the bottom bracket standard evolution. Personally, I never had ANY issues with any of the 5 BB30 bikes I owned (still have one!) but of course saw plenty of issues on poorly set up customer bikes. I agree that 386evo isn’t a bad design if a bracket goes in that uses replaceable bearings but I have to say I’m all in on T47. I have two bikes with t47 and they just work so well with the bigger spindle sizes and easy servicing. Also, if you have a T47 68mm shell designed for outboard bearings, you can use the inboard instead and use your old BB30 crank with a narrow dbca. Takes some doing but you can make it work. As for T47 quality, the Wheels Mfg bis nice (you can swap in higher quality bearings) and I just installed a SRAM ceramic T47 on my melee and was quite impressed with the quality. Also uses replaceable bearings (6806).

[@RICHARD.WRIGHT1]

YOU HAVE EXCELLED in this video, everything I could have said on this subject you've said for me. Except for one thing, you said it in a kind manner, I personally would have disgraced many frame manufacturers, who for years have taken us the bike shops, and punters literally for a ride. WHAT GOES AROUND COMES AROUND sooner or later. Practicallity and functionallity will always beat high end pointless designs which aim to make manufacturers rich! Seriously, do bike brands really believe there are people out there that have no engineering or mechanical background, and do they think we are all so stupid? Two simple bearings in a round hole, how the F can anyone get it wrong? Yet all these great Engineering University grads have done so for years, how? by simply saving money and spending less on quality! LONG LIVE THE BSA THREADED BB! Cheers rant over.

Both Italian and English square taper BBs here (Oh the shame...). The Italian threaded one in my C olnago Super Piu has been in since 2005, with a brief removal in 2012 when the bike was refurbed. Never needed to be retightened (though admittedly the one on my Ti Colnago CT2 did once unscrew on a ride...). It replaced an Italian thread BB that had been in since 1994, but upgrading to REcord needed a new BB due the low profile chainset. I do agree, the English thread BBs are all rock solid. ANd they're all Square Taper, and they all work perfectly.

[@x3631]

clear and very easy to understand in this ever confusing topic... thank you

[@seanrequiredfieldcannotbel1362]

A very good take, but I think you really missed an engineering novelty that is elegant and long weathering. Campagnolo brilliantly moved the cartridge bearing away from the shell and onto the crank spindle. It's brilliant because you only need to press in cups into a shell. The cups accommodate the same sized bearing, no matter the standard. Campag has standardized the bearing size and just left the cup size a thing to be determined. It's a brilliant way to guarantee a certain standard of bearing durability. What size spindle do they use? Who knows and who cares, the stock bearings last forever. If you're lucky enough to have a set that runs out of life, it is a pfaff to replace, but then you are good for another eternity. Campag doesn't get the credit they deserve for this. Imagine my 3T exploro RaceMax running Ekar. 386Evo AND Campag's ProTech BB. I don't know that I will ever need to change out that BB, it's that good.

[@Mapdec]

Campg is easy. If you have a campg crank, use a campag BB regardless of the frame standard.

Totally agree that press fit done properly is absolutely fine. My Bianchi has a BB86 press fit. I use the standard Ultegra SM-BB72-41B and it runs super smooth with no creaking. I do use a thin smear of grease when installing. Take home message if you’re frame is in spec you don’t require an expensive aftermarket 1 piece bottom bracket, the Shimano parts perform perfectly.

[@Mapdec]

Why did you use grease? It’s not in the instructions and will break down the plastic shell.

[@clp91009]

@@Mapdec To aid removal down the line. I use a very thin smear of grease that is carbon compatible. I’m on my third BB now and there is no evidence that the grease has made even the slightest impact on the frame or the BB cups. When I removed the original BB no grease had been used at the factory it had been installed dry and it was very hard to remove.

[@DR_1_1]

I'm curious how long do they last (since you're already at number 3!), kilometers/years, and why exactly did you replace them, ie how did they fail? I'm asking because I have a sImilar BB-RS500-PB, but I don't see how I could remove it myself, in fact I already had several bikes that I chose replace because the axis was too lose (and other maintenance was needed at this point of course, else I would have asked a shop to do it), but my guess was that replacing the ball bearings would have been enough...

[@clp91009]

@@DR_1_1 1-2 years which is about 10,000km for me. I just replace them after that time as preventive maintenance, they don’t typically fail. Over time they become more draggy and don’t spin as freely. I’ve never had one seize but my mate did and he spun a bearing causing some minor frame damage.

[@dperreno]

I've changed BBs many, many times over the years, but never because mine was worn. Rather, I've changed due to new frames and/or new cranksets that required a different standard. Fortunately, all of mine have been threaded, so no issues with improper press-fit installation.

[@williamscalzitti217]

Quick Correction, and not sure why so many people, even really good techs get this backwards: The Drive Side is reverse threads, so to tighten the BB is the opposite direction of the crank, because if it was right hand threads, all the torque applied over time would make the BB near impossible to remove; just like pedals, but the pedal force rotates counter to the crank, so the reverse threads are on the non-drive side. Left peddle, right BB are always in the loosening direction of the torque applied not tightening

[@Mapdec]

Yeah. You’re wrong. The ball bearing rotates the opposite way to the peddling direction and applies the righting force on the outer race. If the bearing were to cease, then the BB would loosen.

[@whssy]

7000 miles on a system that was only on the market for a couple of years in the early 80s and was dropped because the ti alloy was too brittle and many of them snapped. Sure it's the Ti one? The steel ones last for ages, for sure. And the machined grooves were indeed pretty genius. But the Ti SR axles have a very bad rep indeed. Also I seriously doubt you are putting anything like the amount of load on such an axle as you would have in your 20s. I used to wear through a couple of cup and cone BBs a season when I was in my early 20s. Now I'm in my mid-50s I don't think I am physically capable of wearing stuff out prematurely any more.

So went XTR , which were smooth as smooth but the cups arent metal and found the threads started to creak and knurl after about 2k miles. So, binned that and currently running an Uberbike stainless bearing BB. These have Enduro bearings in them, so easy to replace if needed but currently it spins Hambini levels , which would show the alignment is pretty good in my Ibis. As for my Gravel bike being a Planet X Tempest. I found the Truvativ BB;s ( 2 off them ) lasted 6 months each in wet weather. Now running a Praxis jobbie , which also has Enduro bearings , which I didnt know until I took apart and runs pretty smooth . In the end , I looked at easy fix and sensible priced. Rather than King priced ( sold mine on) and higher maintenance.. My worse case senario is now a pair of bearings for 30 odd quid. But I hope that wont be for a while. I binned a Cannondale with a BB30 set up and used the FSA BB converter to BSA and bought Shimano XT chainset to replace the FSA crankset that came with the bike. I guess that going back to the threaded shells , which are more reliable than pressing in etc.

Chris King threaded on my Titanium Baum road bike is the best bottom bracket I've ever ridden bar none.

[@raularrese3926]

My Fav of all time is 386 screw together with 24mm sleeved , stays quiet running on the delrin sleeves and stays tight in frame

[@andrewj100]

Press fit bearings are nothing new, they were used on the Ford Model T! It's incomprehensible that bike manufacturers were unable to adequately implement a fitting standard that has been used in mass produced vehicles for over a century. Even in the threaded bottom brackets, the bearing is still press fit into the threaded carrier and there is still plenty of scope for the frame manufacturers to screw up the installation of the threads (I'm looking at you Dolan). As for metal inserts, 20 years ago I worked for motor racing team, almost every component with the exception of the engine was carbon fibre and if anything needed bolting together is was done using bonded metal inserts, for example, 6 bonded inserts were more than capable of keeping hold of a 750 hp Cosworth engine. The correct solution is a properly bonded in one piece metal sleeve (in an aluminium, steel or titanium bike you don't even need this), an off the shelf FAG, SKF or Timken bearing, and possibly a softer interface insert between the crank shaft and the inner bearings, but even that's debatable. But I guess that would entirely obsoletes the bottom bracket market all together.

[@Mapdec]

Good comment. 👍

[@Bertie..]

I remember when Shimano came out with Hollowtech and I couldn't wait to switch from square taper. Well here we are twenty years later and I have switched back to square taper. Why? Because I can get a hollow titanium square taper bottom bracket from Ali Express with ceramic bearings and outboard lock rings identical to Hollow tech for $45. But main reason is I wanted to run 150 mm cranks. Now after 5000 km they are running buttery smooth and super easy to work on. These aren't your granddad's square taper bottom brackets. State of the art and way better than Kings.

[@Mapdec]

Interesting 🤔

[@janeblogs324]

You can just put ceramic bearings into an old square taper. I've got some shimano square taper bbs that spin so freely the cranks will do 13 free spinning rotation's with 1 kick, $15aud $10usd everyday price genuine shimano. But I'll stick to hollowtechII all day long

[@rd_rae]

I love my c-bear bbright 46mm, no creaking, and the ds bearing is outside of the frame, as close to the crank as on the nds. Happy days.

[@matejzima8210]

Today I learned something. Thank you.

[@JonnyB_UK]

Plus one on the DUB in a 41mm hole woes. Currently scouring ebay for gxp sram cranks 😂

[@oOoACFREEMANoOo]

Wow, shutting down all other cycling channels with one video 🎤

[@grvl307]

Finally someone who doesn't whine about pressfit. I have (had) multiple bikes with pressfit bb's. Never any issues 🤷🏼‍♂️

[@MrSchofie76]

Great review thank you 👍 I would have liked to see some discussion around the Campy UT system and its merits/issues though.

[@Mapdec]

Fair. I didn’t mention it. If you have campy cranks, fit campy BB. End of story really.

[@steve33rocklynch]

Just extracted my 11 and a half year old SHIMANO UN-55. Has been worked on/riden as a courier bike every day during that time. It tool 2 burly mechanics and a couple of vices. Sparks flew. Never been greased, bearings never replaced. And the bike is fixed. She only started making noises a few weeks ago. They sure don't make like they used to.

[@revelationdetailers894]

I have a BBInfinite on the way for my C'Dale SuperSixEvo with DUB (PF30A) to install. I read nothing but the best on these bottom brackets. I will certainly post results after installing and putting some miles on it. Ordered with ceramatech bearings. The problem I see in this industry is they need to all streamline BB systems and create a one piece one model f9r the most part rather than so darn many variations! It is mind boggling the different systems!

[@Dr.Schlitz]

I’ve got BBInfinite in two frames, including a 2010 Supersix that came with BB30 bearings. Really like the BBInfinite products.

[@msheron]

That is good to know, thanks.@@Dr.Schlitz

[@shannonparker7404]

Why has this channel only 20k subs? And Durian rider has how many? The world is blinkers bat shit crazy.

[@Mapdec]

I wish I knew 😂

[@ploegdbq]

It's because much of the value is reading the comments, and, you know, you have to be literate to read the comments? Reading on a video social media website? Madness.

[@rickybarker4023]

Think I need to watch this a few times. 🤯 I’ll just give you a call I think when the time comes👍 live in ulverston so just down the road.

[@alexdi1367]

Really nicely done. Agree with all of your conclusions, though I would note that BB30's bad reputation was as much the fault of other manufacturers as Cannondale. When they invented it in 2000ish, it was intended for aluminum bikes. They didn't use it in carbon until years later and I think they only did that first carbon generation with no metal shell. Later generations bonded in a shell or used bare carbon with PF30.

[@JeyPsCabero]

T47i - I’ll go with Chris King, Wheels Manufacturing and Kogel.

[@geoffyoung8149]

BSA the act if pedalling unscrews the bottom bracket, this makes sense so if the bearings bind you don’t overtighten jnto the frame. It doesn’t tighten into the frame as you pedal

[@Mapdec]

Think again. There is a ball bearing in between the 2 races remember.

[@geoffyoung8149]

@@Mapdec fair comment and if it all seizes it’ll try and spin the cups towards the front of the bike rather than binding it into the BB shell. Every days a school day 😀

[@ArjanGroe]

Seriously, what do the bearings and races change about the thread directions??! The guy in the video clearly says they tighten as you pedal (with BSA)… well, they dont… they hold because you have propperly installed your bb with enough torque. But if the bearings in the bb go bad, the bb would unscrew itself, preventing* the bb working itself into the frame more and more tight. *as if a loose bb cartridge with stucks bearings wont damage the threads… it should really be unrideable at that point…

[@ArjanGroe]

NO, the threads on BSA are not tightening themselves as you pedal, but they actually run in opposition of the pedaling direction, so if your BB goes bad, it doesn’t start eating into the threads, but it will just come loose. With a good BB, and sufficient torque on installation, it should stay. Can’t believe actually that someone who clearly know his business about BB standards either; slips up on that, or has it wrong… either way, very informative video, and cuts straight to the point.

[@Mapdec]

Oh bless. You should research before you try and call someone out. Go and do your homework on bearing procession and have a think about the rotational forces from the crank to the individual balls to the outer race to the frame and come back to me. Maybe consider why the BSA engineers actually designed it this way. Oh. Here’s a clue. If the bearings cease up, then they will unthread themselves. Happy enlightenment

[@BodyKnight]

1st: great video. 2nd: Has anyone with an Italian BB ever experienced unthreading? I'm genuinely asking for. I live in Italy, and i have seen and put together a lot of bikes, even MTB (Nora, Olympia) with italian BB. I have never seen personally an italian BB getting unthreaded. 3rd: I would like to see a video on carbon frames dimensions compliance, in particular in regards to BB and disk caliper attachment points. And your opinion in general on the manufacturing standards for carbon frames in the bicycle industry.

[@Mapdec]

Thanks. Yes. We see it, not for a few years now. The budget Bianchi used to be the main culprits I saw. They just unthread a bit, increase the preload and then kill the bearings. We have lots of vids on that subject. You will enjoy the channel

[@Vandenbos717]

What a great video absolutely something to favorite. I’m absolutely a fan of bb386’s with the wheels mfg bb’s.

[@TeilzeitSender]

As a mtb rider without the urge to ride carbon bsa works just fine :D nice informative video.

[@estelja]

I still like the heel clearance of BB30. I’ve got an ‘07 carbon Cannondale Synapse with an aluminum bb shell. The bearings press in just fine. I’ve run Hawk steel bearings and Enduro ceramic with no problems.

[@jonathanhowson6420]

Its Chris King screwed into a threaded bb shell on a Santa Cruz frame. My Chris King bb is about 14 years old, its never creaked and its still running on original bearings. Noone can beat that.

[@Mapdec]

I bet they would still warranty it too.

[@dylangrantz8124]

yep I agree Chris King makes good bsa bb but we all are not dentists.they are crazy expensive. Just like the headsets are great but overkill for most humans. Heck while we are at it get some hubs also. I am so glad you are giving techs the blame they deserve in the press fit bb issues everyone has had. It is all not all on the manufacturing side. Plenty should have been caught by techs

[@sketchy0078]

I'll stick with my square taper BB thank you. I just built up an NJS bike with Dura Ace cranks on a hatta BB. Easily the smoothest and strongest cranks and BB I've ever ridden.

[@catherinemacalisang5782]

ENDURO BEARING for my press fit BB is the best. Using it for 3-4 years now without a problem. Of course with regular re-lubrication using maxima or XHP 222 grease.

[@endcensorship874]

I think some factories are bad about bonding their BB into a carbon frame, I'm certain of that. But I"ve had a my Scott Addict R1 since 2007 and haven't had a single problem at all. I have a Rodeo-Labs gravel bike with T-47 internal, and I have a White Industries BB and I've been very happy with it.

[@davegee124]

i used a cane creek BB into a press fit frame for my grandsons bike with carbon DUB cranks, its got a threaded sleeve so it pulls both halves together and tightens like a threaded BB,works briliantly, no squeaks or clicks nothing,ran 2 years no problems at all.

[@gm9559]

My 25 year old Litespeed Titanium frame has a Standard Dura Ace 11 speed R9100 BB. Four years and many kilometers in every weather...it runs like new. Threaded is and remains best.

[@PeakTorque]

Shimano pf86. Plastic cheap bb and lasts for years. The best sealing in any BB. There is NO need for anything else if the industry could make a round hole

[@ChrisJohnson-ez5jq]

Which would you recommend for T47? (People who don’t sub to Peak Torque really should - his vids are great.)

[@davidnicholson6680]

I have a Seven Carbon/Ti frame with a titanium BB30 bottom bracket shell. NTN bearings were pressed into the shell in 2018 and have not been touched since. The bike has done many thousands of miles. It's still the smootest BB in my fleet of bikes. Even BB30 works well if the frame is well made.

[@gweflj]

That’s because your frame his built to a high tolerance standard. 90% of the industry is junk.

[@FGIRAFFE]

This video is not for the fainted of heart! I think you were right, industry should start thinking about the cyclist first.. That was rough. But thanks for the content.

[@adam1885282]

I've never had a single issue with my bb30, just replaced the bearings once in about 10k miles. However, give me BSA any day, much better design.

[@lee1210mk2]

It is not a better design, It's a lazy one!

[@NickJames-vh7dl]

Hi have a BB71-41 press fit, its in perfect working order but can you suggest an upgrade to style of BB , lighter and smoother.

[@DR_1_1]

Similar BB-RS500-PB here, I'm also curious what could be a better replacement in case it fails?
