I haven't been in bicycling for years, yet I'm still passionate as its the best mechanical contraption ever engineered for the human body. You're videos have enabled the masses what is current, what is technically superior, and what is the new standard in the industry. And your "how to, DIY approach" is quite amazing. Anybody that is "technically challenged" can perform their own changeovers and upgrades with your easy narration and clear videos. Thanks again RJ. Keep-up the great work. .

Looks way better RJ. 😎 Speaking of Raleigh. My friend found an ole Raleigh full suspension & used the threadless front end on his motorized Haro. I gave him 20 for swing arm which happened to fit my broken Motobecane DS 600 swing arm. Couldn't believe it bolted right up to it. It also raised it up some 👍 👍 Except for the cable stops didn't line up. But my friend said there's something to fix that. Sure was nice riding bike until that last 8 - 10 ft wall I jumped off of. Broke a weld & couldn't find another one

RJ has the best bike videos. I built a custom fixie for my son, and restored an old tandem using parts from two scrap bikes and a tandem frame I got for free, mainly with info from RJ's videos and memories of working on my Schwinn 20 years ago. Now I'm restoring a mountain bike I got for $20 on Craigslist for my husband.

I'm currently running an old '93 Ultegra crank on a square tapered bottom bracket and was thinking about upgrading to Shimano 105 5800 Hollowtech on a bike I've owned since new and have recently rebuilt. Your tutorials are superb, I've learn a lot. Thank you very much.

[@DavidCulshawmer-r]

One little tip for the preload cap is to screw it in tight then unscrew it then just screw it back in until it just touches the crank , that will set the preload perfectly with no undue stress on the bearings , nice vid mate keep them coming ;)

[@501jonesw]

Another great RJ video. I recently picked up an old FUJI Sagres that had been sitting outside for a very long time. Everything is badly rusted but I'm slowly bringing it back to life. The paint and decals are in good shape. Taking care to not damage the bike cosmetically, I removed the wheels and bolted the frame to a 4"x4"x10' with two long lag bolts run through the kickstand bracket and a scrap 2"x4"x7" across the rear of the frame, as clamps to hold the frame so I could get leverage enough to twist the seat post out using a large pipe-wrench. That went well with the help of some boiling water on the seat post tube and some PB Blaster. But then came the bottom bracket which I removed today. After removing both ends I discovered 12 very grimy ball bearings caked in old grease and sand on one side and 8 dry and equally bad bearings on the other side. There is also no dust cap inside the frame so the rusty crank axle may be trash. After watching this video my question is; how do I measure to determine what size bottom bracket to purchase to convert the old school loose bearing system to the sealed bearing bottom bracket? Thanks for any help.🚲

[@Toto-is8ci]

My friend inherited his dad's Zunow Hummingbird and wants to put Hollowtech crank on it since the drivetrain is worn out and needs to be completely replaced. I balked a little since this is such a classic bike and it has all its original components. This video will let us get it done. THANKS RJ!!!

[@lastpme]

Thanks for the video. I just took by 2017 mountain bike to upgrade my drive train, the tech guy barely looked at my bike and said he could not do the upgrade. I had the parts, but just wanted it professionally done. Will do it myself and take it to another shop to do the alignment of the gears if I can't get it work. Thanks.

[@cradleofphill]

Hey mate, just wanted to say a big thank you for all your uploads and because of them I was confident enough to upgrade my own bike. The only thing that's original is the frame and forks lol. I've just done my final upgrade (for now) changing out the old cotter pin crank to a hollowtech II. The difference is night and day! I couldn't be happier with the bike now and I owe a lot of it to you and your videos. So thank you for all the knowledge you've passed on and I'll pay it forward to someone else. Cheers, Phil.

This is just great! Finally I get the answer I was looking for since a while: So _it is possible_ to change the old massive axe for a new modern one!

[@dblissmn]

Really easy to follow video. I'd also encourage mentioning the simplicity of the Shimano bottom bracket design. No little ball bearings, hardly any nuts to tighten, no more cone wrenches needed once you're onto the new stuff, just one very large bearing in each end of the bottom bracket part, and still the ease of fit and alignment that goes with threaded bottom brackets.

[@deanhps]

Once again, thank you. Very helpful indeed. I have an old Paconi with Shimano 600 and a suntour sprint crank. I’ve been thinking of updating everything to 105 11 speed instead of getting a new bike, the bottom bracket part was confusing me a lot, but now thanks to you I’m going to give it a shot!

Excellent video, made it totally clear what to do. I didn't have time to get my hands on a BBT-59 so I used the plastic adaptor. It did not last long! I dunno why they don't supply an alloy one (well, yeah it's cheaper to go with plastic I guess). Anyway, I managed to screw the BB pretty tight even with a crack in the adaptor ring. I've now got the latest '11-speed' 5800 105 chainset installed. Running it with an 8-speed chain and a 7-speed cassette on an 11-speed hub (with correct spacer, again thanks to your video on the matter) and everything's smooth as hell. So much for compatibility issues... I'm gonna upgrade to the full 11-speed 105 groupo eventually but it's nice to know the new parts work with older stuff. Again, many thank for the great videos!

[@RJTheBikeGuy]

The point of the video is how. Not why. But with external bearings it can make the cranks stiffer and less flex. They allow for larger bearings, so potentially longer lasting. Lighter. You can research them elsewhere.

Really helpful. Am about to upgrade the 3 x 9 speed Tiagra on my Trek 1.5 winter bike to 2 x 10 speed 105 and will be taking out old square taper bb and replacing with one of those new BB-R60 Hollowtech ones. I've seen various people say the Shimano tool adapter for these new smaller bearings just shreds (a one time only use tool) so I've ordered one of the Park Tool BBT-59 tools and also one of the BBT-10 ones for the tensioner caps (I just don't trust the little plastic disc ones... had plastic spoke tool that came with some Mavic wheels just disintegrate first time I tried to use it). Will get enough use out of them to justify owning as will also fit my girlfriend's bike and bottom brackets never seem to last all that long.

[@sonofsun4]

WHAT IS THE REASON TO CHANGE 27 SPEED BIKE TO 20 SPEED BIKE? If anything change it to 3 x 11...it is always better to have more speeds to spread the force on different slopes....right?

[@matthewbrooker9817]

+Sunshine Yes more gears are better for a wider range of terrain that can be covered. However in most places roads would rarely became so steep that you need to use gears 1, 2, 3 on a 3x11 to go up a climb an also no one who is an amateur cyclist would go so fast that gears 31, 32, 33 would be needed. So therefore it is a lot of extra unnecessary weight slow someone down while climbing. Also having 33 gears would make the chain rub in nearly all gears making it inefficient and very noisy.

[@Goriaas]

"chain rub in nearly all gears". Nope only in small-small combinations for me, which I never use. Middle ring and even big-big work fine. "alot of unnecessary weight" a granny cog weighs a few grams about 30-50g. setting up gears can be more finicky initially and you do have a few extra grams, easily outweighed if you ever come across some crazy steep hills. Really as a non-pro there are basically no arguments against triple

RJ, Love your videos, finding them very informative since I maintain all of the bikes in our house hold. To the point, typically i tighten the preload cap just to the point where the "security tab" pin will drop into the hole and be flush with the crank arm. It didn't look like you did this. Did my eyes play tricks on me? thanks , keep them coming.

[@RJTheBikeGuy]

It was pretty loose and went in pretty much on it's own.

[@afesquivel]

I figured since I forgot to mention that I have a triple crankset and takes a spacer. With that in place it takes a couple of turns, by hand , before it would flush in. Anyways, thanks again

[@graemehodgson5544]

Very clear and beautifully presented, nice one

[@camerond8176]

FYI - There is NO preload on the hollowtech bearings, it's a cartridge bearing. When you install the left crank arm the plastic tool is to pull the crank arm on to the spline and ensure it's fully seated against the splines and back of them. As long as the arm is fully seated, flip the tab down, and tighten the pinch bolts to spec.

[@DEAR7340]

Very nice. I am in the process of updating an old Panasonic Team America (1984 Columbus SL) frame. I had the tools and experience to remove the old crank, as you demonstrated nicely. My concern was whether the Hollowtech II (English) was going to thread in without any additional adpaters or measures or fuss. Definitly saving this video to watch again, once the frame is back from the powder coating shop.

do you have to make any considerations to the diameter of the frame bb shell when converting bbs? Also chainline? could there be issued with FD limits?

[@RJTheBikeGuy]

The shell diameters have standards. Chainline isn't significantly changed.

[@zakneutron]

Nice. Be good if your torque measurement were consistent. BB = inch/pounds : Crank bolts = Newton/meters. Personally, I prefer Newton Meters and most Shimano recommendations are in Nm . Would appreciate some insight on which BB you chose due to the width of your BB shell area. Great instructional video. Keep up the good work!

Alright RJ , I always wonder what that splined tool was for on the small end of the Park Hollowtech BB tool ! ...

Pure excellence! Many thanks!! I'm inspired to do even more complicated bike maintenance han I ever have attempted before and maybe even try some bike modifications. Question, if you have time: I just bought a 2018 Raleigh Rowdy (16" wheels) for my 5yo son. The bottom bracket seems to have a bit more friction than I'd like, and I think I can feel the ball bearings like when a headset is cranked down too much - but it's definitely not clunky or lose. It's a cheap, square taper 68 or 70mm cartridge (I think), listed at 113mm in the specs (haven't had it apart... yet). Is there any way to adjust this, you think? Also, I was thinking of maybe swapping in a Shimano UN55 - do you think it might be worth the effort? Thanks again, regardless of if you answer.

[@lukas4610]

Hey RJ! I recently got all the parts from my vintage frame and when the paintjob is done I'll be able to upgrade the bike with some new stuff. The drivetrain that was orginally on the english threaded (68mm) bike was Shimano exige sport. (square tapered with biospace sis 52 and 42 cranksets). Since the crankset, chain, cassette, front and rear derailleur, front and rear wheels + hubs have worn a lot and have cracks and dents all over, I thought it best to upgrade to a complete new drivetrain (keeping the brake levers and the old style levers to change gears). The problem for me is however that I don't know where to look with my limited knowlegde in parts. What I am looking for is a high quality drivetrain preferably between 350 and 450 euro's. I still want to keep the old brakes levers as well as the levers situated on the frame next to the knees to change gears with. So I have to be sure that the new derailleurs and brakes are compatible with those levers. What I eventually found was the Shimano 105 (5800 Groupset - 52/36 11/32) which I would be able to afford. Do you have any thaughts on this, or do you maybe have other suggestions/ possibilities? Do you know wether the levers I mentioned above are compatible with it? Thank you already in advance, your video's are a great source of information!

[@robertp7209]

Measure the width of your bottom bracket, if it is 68 mm for a road bike, you are in. Probably threaded as this bike. Just take bottom bracket apart to find out, or Google it. I bet others have the same Merlin and have modernized it. I’m doing my Kestrel 96 200 SCi.

[@z1522]

Au contraire, facing is pretty essential; the one-piece sealed units aligned both bearings permanently inside the inner canister, so shops lost the skillset. External cups once again make facing important. You can tell if any paint remains on the face of the frame at the BB shell, it has never been faced, which means the cups are unlikely to seat squarely parallel to each other after tightening, leading to more friction, and premature wear of the external bearings. Proper facing tools cut material off the outer faces until parallel, and cranks will live long and prosper.

[@dosetti]

More likely old bike has chipped paint on the very edge outer bearing sits so i think facing is a must. Of course one can try getting lucky but i prefer doing it properly.

[@carlrichards9333]

Great video, thanks! But why do you need to preload the bearings with the BBT-9 tool on this kind of external bottom bracket? GXP bottom brackets do not seem to require preloading of the bearings: what's the difference? Thank you!

[@DeepakKumar-lv4te]

hi RJ, nice vid. Just to say that I thought getting the frame faced (and thread chased) was in order to ensure both bearings seat exactly parallel - and hopefully aligned straight ahead. Otherwise if both faces are not exactly parallel then when installed, there is uneven pressure on the bearings giving premature and uneven wear on them. I am no expert but thought it might be a useful contribution. Peace RJ.

[@sonomama82]

I have an old Raleigh Elan that is 2X7 and I want to upgrade the crankset and bottom bracket. Most new cranksets are onlly 2X10 but does the crankset's gear count actually matter?

[@RJTheBikeGuy]

+sonomama82 Yeah, the cranksets for 2x10 have the chainrings closer and won't always play nice with a 7 speed shifter. So you can either upgrade to 10 speed, or add some very thin spacers on the chainring bolts.

Is hallowtech 2 the most popular standard nowadays for the traditional 68mm bottom bracket shell like what we see on RJs bike ?

Can you do a video of pulling a PF30 BB and installing a shimano Hollowtech ii?

[@aidavcomedy]

What if you’re installing a mountain bike crankset on an old road bike, wouldn’t you need the mountain bike BB because MTB crank’s spindles are longer than road bikes? So you need the spaces to make up the difference?

[@RJTheBikeGuy]

No. The longer spindles on MTBs has to do with the triple crank needing it.

[@Prizzly92]

have you seen any hollowtech 2 bottom brackets with french thredading? I have an old Motobecane c5 that I'd like to upgrade.

[@RJTheBikeGuy]

Nope. You are going to be limited with that. There are some French threaded cartridge type square taper BBs.
