- I've got a new Shimano 12 speed crankset and Wheels Mfg bottom bracket to install on my bike. In this video we will be unboxing th Shimano 7100 crankset, removing my old crankset and bottom bracket then install the new parts. It will be an adventure!
0:00-0:16 Intro
0:17-2:23 Unboxing
2:24-2:47 Tools I used
2:48-3:06 Weight of new crankset
3:07-4:16 Removing the cranks
4:17-5:04 Removing the BB
5:05-5:28 New BB
5:29-6:39 Installing the new BB
6:40-8:31 Installing the chainring
8:32-10:43 Installing the cranks
10:44-12:42 Wrap up
Piano black, pairs well with the background sound track. Nice looking cranks!
Thanks! I've been trying to hunt these down for a while.
Good stuff Brian.
Thanks, Pat! It was fun.
The Park Tool TW-6.2 is not designed to be used to loosen bolts. A breaker bar is ideal for removing bottom brackets.
Ok
Great video, Thank you. Pity Shimano dont provide the tools to fit the crank in that massive fancy box.
Nice...
Nice video, interesting... There where no washers /dust seals included with my shimano bottom bracket. Guess I'll have to go to my lbs, hopefully he will have some for sale.
6:22 I too do the same, 40 nm, I can't even go past that, I am not strong enough. but that would be overkill anyway. Never had any issues with 40Nm.
The wear on the crank axle can be due to metal on metal contact with bad tolerances on axle or bearing. if the BB has a sleeve thing to protect the crank it won't happen as fast. But I've seen in a vid by Hambini, showing Sram GXP cranks where tolerances were really bad, resulting in this butt much worse. You probably don't have special tools to measure tolerances, he has special tools for it, i forgot the name of it. He has serval types of tools for measuring tolerances of various types. butt some things are so bad even a vernier would easily show bad tolerances.
You didn’t try the elliptical chain ring??? I almost assumed you had one? My Dub BB always get Fowled between the small bearing hole and the shaft. I usually take it apart twice a year and clean it. I’m surprised you weren’t getting creaking? Mine look like yours, hard to keep clean!
I've never tried an oval chainring. I might after this one wears out. I think the dust wipers make a difference when keeping the BB/crank clean.
I've got the same crankset
They do look really good!
That's cool Brian. I've never done that before. Interesting. Have you ever considered going to an oval?
Thanks Harry. So I know people swear by them but it hasn't been something I felt I needed.
@@BrianVaughn I wondered. Cycle just did a short video on the difference.
Yeah, it's one of those things that has it's pros and cons. If you give it a shot let me know how you like it.
Holy crap that’s a nice way to damage a torque wrench
Amazing it still works and goes past the nm used to tighten it.
What is? Tightening a BB? Rubbish
a torque wrench is not a breaker bar.. rip
Got the job done
@@BrianVaughnyep but i would not use my Hazet torque wrench for that lol. Would hurt my feelings
It's a torch wrench that goes to 60nm. It can handle it.
What prompted the switch to new cranks?
I was looking for a better experience and felt replacing the SRAM cranks would help. The rest of my drivetrain is shimano.
@@BrianVaughn I am not sure why that would be needed, you only needed to use a chainring with an offset to suit, I recommend to use 6mm offset if it is feasible on your bike, not all boost frames can use non boost chainrings, so you have to use 3mm boost chainring. if the chainring suits the chain there should not be anything hindering a smooth experience.
but offset also depends on the cranks, if the Sram cranks for example had the chainring be mounted too far out that would reduce performance.
Newton meter.
Nah I go by how deep my grrrrr is when tightening.
great video, but do not use the torque wrench to loose bolts, you will damage a very expensive tool
He didn't. The BB drive side is reverse thread
@@markfenwick5441 hey man, sorry but I don't think so, he removed the chairing at 3:24 minutes using the torque wrench! He should be using any wrench but torque wrench to lose anything!!!!
Don't worry guys, the TW 6.2 can handle all the things. That's why it's called a tool.
@@BrianVaughn once again Brian, the tool is not for this purpose, however, the tool is yours, the money spent was yours, no more comments. Thank you.
7.30 In my opinion this is a stupid design, they sohuld have had the right crank arm come off, and be able to install it easily without taking the axle out of bb.
