I cycled around 11K km this year, including two long solo bike trips. 1300 km and 900 km. In the process I understood one thing: moving from square taper to any kind of BB with external bearings and hollow axles is actually a downgrade. Yes, they are lighter, but they provide zero difference in actual riding and pedaling efficiency (unless you are an UCI racer who counts every gram), and they are much less relieable. Over the last year I broke 2 axles on Hollowtech-II and GXP cranksets, and now I'm perfectly happy with a good, cheap and indestructible UN-55 square taper. Just for your consideration.
Just changed my square taper bottom bracket to another campagnolo square taper bottom bracket. Last one I had for 24 years pretty good if you ask me and yes I put a lot of miles into it.
No long ago I did just such an upgrade to my Salsa Timberjack...the NX/powerspline was replaced w/ a GX/DUB BB. At the same time I converted to tubeless. BTW I really like the content of your channel...always very imformative and well presented! Thanks for all the time and effort you put into it.
Good video, but I have never seen a bottom bracket undone with 2 spanners before when 1 spanner is all that's needed. Use a single adjustable spanner to tighten the removal tool to the crank arm first, then use the spanner to tighten the 2nd part up whilst holding on the crank arm. Holding the crank arm acts as a better lever than the looser extra spanner, and it saves the spanner causing an unnecessary scratches in case it slips. Have fun.
Square taper bottom brackets are bomb proof! I changed all 5 of my bikes with Square taper after having a lot of problems, I can stomp the pedals if I want and I never have a problem! The video was well done though!
That is why adjustable cup and cone square taper BBs were the standard for decades. Weight saving is the only valid reason to use anything more "modern."
super easy, Just upgraded my worn cheap square tapered crankset to an Alivio hollowtech II. Now it's lighter, stiffer, derailleur works better and it's easier to maintain
Square tapered BBs are pretty much maintenance free if assembled properly. Also they have better water resistance, since the tolerances are tighter. I give my bike hell everyday and still haven’t got any problems with it, I even converted it to 1x. I think there are better things that can be changed for that price, which would have much greater impact performance wise.
@@LoveMTB fc-t4060 44/32/22 weight about 1200 gr include bb. Fc-m470 ( for an example ) weight 696 grams + 260 grams for bb-es71 bb = 960 ( 1000 gr with bb-es25/300) . So what is cheaper, lighter and stiffer ? Gotch ya ;) or.. fc-m750 - 680 gr + bb-un72 - 260 gr = the same ( and still the stiffnes is better or the same as alivio fc-m4060 ) You all just didnt use good square taper crank or octalink crank. Maybe You were born to late ;)
Excellent video! I plan to make the upgrade to hollowtech BB and replace the 3x7 Tourney drivetrain on my Raleigh Tarus 2 with 1x10. I already upraded my freewheel to a shimano freehub and 8 speed cassette as stage 1. Your videos help a lot. Thanks for taking the time to produce them.
You make it look so easy,your bike is new with sealed cartridge that comes off easy with no dirt. Well used old bikes have hard to remove,filthy,stubbon bottom brackets!!!.
You don't appreciate square taper until you start riding in a very dusty terrain with alot of fine gravel like stones. Those small particles really affect hollow tech and press fit bb
Changed four of my hollow tech fitted bikes back to square drive after getting fed up with wearing the hollowtech versions out. The most reliable of the hollowtech is the shimano. Don't touch the others. Had to resort to changing the chainset from GXP to shimano 105 after getting through three of their BB's in 12 months before I finally gave in! Each manufacture has their own BB design and chainset crank diameter, so you can interchange them.
I’ve a few bikes myself - two with a Hollowtech BB and one with an old school Square Taper Bottom Bracket. In my experience too, I’m inclined to think that the Hollowtech wear more quickly than good quality Square Taper Bottom Brackets, however, at least the Hollowtech BBs are a little easier perhaps to replace than SQ Taper ones. The new Hollowtech Bottom Brackets are clearly more fashionable now and sexier than the old school SQ Taper ones, but in reality Square Taper Bottom Brackets remain a perfectly good and viable option on many bikes! Using a Hollowtech Bottom Bracket though, does of course provide access to and allow the use of a wide range of newer-style cranks which are not compatible with SQ Taper Bottom Brackets. I’d like to find out though whether swapping Square Taper Cranks with Cranks designed for Hollowtech introduces problems and issues with the bike’s Chain Line. Looking at the Crank on the frame in this video here, it would appear to be far too close to the chain stays, even without a chain on it. Changing a BB on a bike is a relatively easy thing to do, but if you’re changing the Chainset as well it’s only half the job and setting up a well-aligned and well-adjusted Chain-Set on it is quite another matter.
@@nigellee7892 I have a video about chainlines and cranks if you want to check it out. Actually two, Shimano - th-cam.com/video/JjrpTkJG6Qc/w-d-xo.html and SRAM - th-cam.com/video/t0X3nlwOoAQ/w-d-xo.html
These look convenient, but I hear they are not as hardy or reliable as a square taper. On my old 2007 Trek 7100, the square taper cartridge BB never wore out. In 2019 I bought a new Trek Verve 1. The square taper BB in it lasted to this week, I just replaced it with a new Shimano square taper BB, works beautifully, hoping it lasts a good long time.
Nice video... I was looking for this exact process as I have a Trek Marlin 4 and its been in need of a cleaning on the bottom bracket for some time. Thanks!
Hi, thanks for the video. When you installed the crank set how does it work with the axle? Because the other bottom bracket had an axle and the new one didn’t. So did you have to change the cranck set as well?
After buying the extractor tools and figuring out sizing probably easier cost wise to take it to local bike shop and have them do it. It’s not like you’ll need those tools again.
Just Picked up a Vintage 1994 Parkpre AL U MAX MTB missing wheels .

What BB can I use to replace the square taper on my 2022 Marlin 5? I want to install Raceface crankset. Thanks youve helped me so much on my upgrade path.
When I redid my old road bike, 68mm, the Shimano bottom bracket was 1/2 lb lighter than the original Campy cartridge type. Double Ultegra crank was lighter by 0.15 lbs over Campy triple racing crank. The triple had a slightly longer shaft, the Shimano was standard.
I have a Shimano Tourney double chainring. It says to use a BB of 110mm. The BB I have is a Shimano un300 110mm, I'm worried that the crank will be too close the the frame and the inside chainring might rub against the frame?? Does the inside of the crank seat up against the chain stabilizer collar? The BB is for a non chain case.
I tried it on my Carrera Hybrid, changed it to single using a Shimano FC R7000 50T with a Shimano SM BB52 BB, the axle length was too short making the cranks hit the chainstays, went back to a square taper in the end!
@@LoveMTB Yeah put all the spacers in that come with the BB & added another 2mm spacer & the crank just cleared the stay, however, as I'm sure your expecting, it was spaced over that much there was not enough left on the drive side to fit the crank on.. 😂 At the time I knew nothing about BB's so relied on my LBS to recommend & supply me with what I needed to do the job.... At a cost of £200.00 I quickly learned & swiftly returned the parts & sourced a new square taper BB & single narrow/wide chain ring with cranks & completed the job for around £60.00
Hi, I have an 1x8 drivetrain with square taper. I would like upgrade it to new Hollowtech and ect. , but I found only on the market crankset that only for 1x10, 1x11 drivetrain compatible. Can I still do it using the spacer to set the chainlink ? Thanks for help. Great Video !
How tight is that 40 nm? My tool seems flimsy and am afraid I might overtighten and damage it. Cant seem to find any video where it shows how tight it should really be. Thanks!

Oh ok so did u use the Stock crank arms? From the 2x8 set up?

My old mountain bike that I’m refurbishing is 68mm width but the inner diameter 33mm. Will a hollowtech bb fit that diameter? Sorry I’m new to bikes so trying to learn as I’m rebuilding. Thanks
Thanks for the great Video! Is it necessary to upgrade the crankset if i upgrade the bottom bracket? I also have a 9 speed bike, but at the front i can change the drivetrain from 3 to 1? On the back i go to 12 speed. Thanks for your help my Friend

I was thinking that myself my brother has a hollowtech type to and he need a new one every year and I have a square taper only every got one of them
Exactly what part of the axle you broke? You mean the splines of the non drive side?
If Suguino hasn't gone hollow neither will I.
However my ISIS drive on my cx bike has been going for 12-13 years now.
Really appreciate your clear, concise breakdown of the options as well as your methocial approach.
