[@kovie9162]

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.

[@peglor]

Square taper cartridge BB's are far more durable for the money than any of the current options. They're also a lot heavier and the axles snap when they're ridden hard off road, or on trials bikes, and holy crap do they let go with a bang and give no warning at all that there's a fatigue crack working its way through the axle until they let go. All the hollow axle setups where the axle is part of the crank mean the cranks need to be thrown out eventually unless its ridden in clean dry conditions as grit works its way between the axle and the BB bearing, eventually wearing the diameter of the BB axle out of tolerance, so there's still visible play even when installed with a brand new BB. It takes about 10 years and maybe 10 000+ miles of riding in wet muddy conditions to do it though, at which point fatigue cracking in the cranks themselves and pedal thread failure aren't far off either, so still not bad value for money on the XT crankset I killed that way.

[@bradtowne2305]

@@peglor I don't know, but snapping square taper BB's seems like it is a rarity rather than the rule, even if riding off-road. They are cheap, reliable and plentiful. They just work, and yet, we have created so many standard, some of which literally are no longer supported making the frames obsolete if the current BB fails. I lucked out, as my cross bike has a Press Fit 30 that is the standard design. Others had very specific press fit systems that are no longer manufactured, not even by Wheels Manufacturing,

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.....

[@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).

[@bicyclist2]

I started with the sealed cartridge square taper bottom brackets back in the early 90's. After the introduction of the press fits, I got a little lost on all the new sizing and standards.

I use square taper, BSA thread bottom brackets. There is no getting around the fact that you can round them, you can get the crank part seized on etc. however, they are 15 bucks for a whole one, easy to take out, easy to lube, and you can just buy bearings if you want, don't need to replace the whole thing. But then again I don't get dressed up in lycra and cycle in the middle of the road, I just spend my life using it as a get around.

not sure what bike your looking at but if your building up and want a killer square taper check out the white industries sq bottom bracket and matching cranks. just my 2 cents.

[@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.

[@zackbaldman]

Campy doesn't get enough credit period. Excluding EPS, they've had some really great products since back in the friction days when they were more mainstream.

[@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.

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.

@@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.

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.

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.

[@wiseoldman5841]

It is a Teledyne spindle. They added steel races where the bearings were contacted. Agree on the sugino cups..went through them pretty regularly. The campy set was a huge upgrade. I cleaned and repacked every week. Along with the hubs. I'm still 155 pounds, so there's not a lot of weight on the system. I did get talked out of an aluminum spindle by my local shop. They were suicidal.

[@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.

[@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.

[@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

[@Kermitonwheels]

Wow. What an incredible summary!

[@jamlee344]

This channel is brilliant! Straight to the point with great information. Keep it up guys! 👍

[@Mapdec]

Thank you.

[@oOoACFREEMANoOo]

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

[@redauwg911]

thank you for making these educational videos

[@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.

[@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.

[@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.

[@johnkyle-kl6vk]

I've ridden Pinarello's ( Italian thread) for 10 years ( average 15,000kms per year and I have never had one come loose. Currently running a Hambini TI BB with a SRAM dub crank with no issues. and I have to say the Hambini BB is the best BB I have ever ridden.

[@Mapdec]

Cool. In every example there is always an ‘I’ve been doing x for 10 years’ that’s awesome, but we do see quite a few more bikes than most. So far this year about 1200

[@georgekrpan3181]

Yay, I have T47 internal. That's the reason I chose my bike.

[@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!

[@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.

[@bengyantonio2965]

Great video on BB's!! Wow there's a lot of BB standards out there!

[@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.

[@GreDrums]

I actially have BB30 on a Tarmac sl2. Bearing slide into a metal sleeve. Still happy with it, changed bearings every 2/3 years. Recently installed the skf mtrx bearings, let’s see what the lifetime on these is!

[@mathw7173]

How does it work for you? Any issues (wobble, creaks etc)? I have a TIME Izon from 2015 with BB30 and currently my entire rotor crankset wobbles like crazy and im considering whether to buy new high quality BB30 bearings or buy a twistfit onepiece solution with external bearings

[@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…

[@adrenna123]

For press fit, look at Wheels Manufacturing. The BB threads together internally in the press fit space. Never creaks, maintenance free. I got 39K miles on my last one and had it replaced with the same. Just picked up a Bianchi Otlre Pro and had the pressed in BB replaced before I ever rode it. This is by far, the best BB on the market. Wheels Manufacturing.

[@Mapdec]

They are called thread together bottom brackets and they place a horizontal clamping force on the frame. They can fix a problem of an oversized frame, but they are not a preferred solution for a frame that is ok.

[@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.

[@cygnusxl5]

Hi. Another nice informative video again - luckily I have no bikes whatsoever with PF Bottom Brackets. I like the idea of the T47 Bottom Bracket and feel that it will probably undergo further developments/improvements in the future as bike manufacturers have begun to subscribe to that system. While I'm here, have you done a review of the Cinelli Nemo Tig Frameset or are you likely to? The Gravel Version looks like it would make a nice all round 4 Seasons Bike? Keep Up The Great Work. 👌

[@Mapdec]

Thank you. I only review what customers buy from us. If someone orders one, it will probably go on 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.

[@tonyjames5444]

Need a new bracket for my old 2014 Cannondale Synapse 105 with FSI crankset, great video but as a non bike mechanic this was a tad confusing:)

[@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.

[@robbeelsas]

I always get Praxis T47i bottom brackets just because they're usually the cheapest decent option

[@pascalhibon7928]

Great video. Very confusion all these different "standards". My bike has Rotor press fit 4130 BB's. It has something over 2000 km and one of the bearings need replacement. Today I removed the cracks to have a look at it. The damaged bearing has some traces of rust. So there is an ingress of water somewhere.

[@Mapdec]

Yeah. That’s a terrible combo. Very small bearings. Will need perfect alignment to work really. Also impossible to seal well. You’ll enjoy the rest of the channel.

[@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.
