Shimano's New 12 Speed Gearing - Is Bigger Better?

[@Cyclingallthetime]

I have the new 12 speed di2 ultegra group set on my new tcr which came with 52/36 & 11/30 which I've just switched to 50 /34 & 11/34 cassette for my upcoming Alps trip. The changing on both sizes was immensely smooth, even under high power, and the additional clearance built into the new brakes had eliminated disc rub. Compared to my sram force etap, its light years ahead although not as aesthetically pleasing on the eye in my pov. Anyone thinking of upgrading groupsets, I would say based on my experience you would have no regrets.

[@michaellee7046]

Did you have to get a new chain for the setup change?

[@jonmaloneycycling7593]

thanks for sharing

[@Cyclingallthetime]

@@michaellee7046 I didn't because smaller chain rings on the front and larger on the back balanced out for sizing. I would have had to remove some links should I have just changed the front, or a new chain if just putting larger on the rear

[@larrymcgoldrick3471]

Glad to see someone bring gearing into the focus it deserves. So many people, for so many different reasons, are on the wrong gearing for where they ride and their ability. Thanks!

[@Steve-jo3cl]

And the guy giving the advice is riding a 54/42 front chainring !!! PLEASE !!!!! no amateur cyclist ever needs a 54/42 or even a 53/39.... example 52T front and 11T rear @ 95cadence is 35.2mph/56.6kph if your holding that you should be in the pro peleton... so again I ask why on earth would u ever have bigger than a 52/36 or maybe 38 set of front chainrings on.....

[@larrymcgoldrick3471]

@@Steve-jo3cl Couldn't agree more. I run 11spd 46/30 chainring and 11-34 out the back. Nice to see the subject brought up. Needs to be discussed much much more than it is, was my point.

[@Steve-jo3cl]

@@larrymcgoldrick3471 Fair enough, well theres a guy called Durainrider on youtube that has been pushing smaller gearing for 10+ years

[@jonmaloneycycling7593]

thanks for tuning in!

[@CrabgrassFarmer]

Another highly informative and time-efficient video. I'd just like to add: If your gearing isn't easy enough and you ride decent hills, you are forced to put out more watts to keep going than may be ideal. This higher watt output wears you out faster because it may be forcing you into your anerobic zone. This "burns matches" and crushes you compared to what you could be doing with easier gearing.

[@jonmaloneycycling7593]

Thanks man!!

[@jkotvis]

Glad to hear that you’re fine dude. In hospital I sometimes see people break just about anything while jumping with a bike of just the sidewalk. Be safe and keep those vids coming 😊

[@jonmaloneycycling7593]

thank you. all the best!

[@michael4305]

Glad you are safe after the crash and your bike survived as well. Great videos, look forward to viewing them. Live in Oro Valley, always riding out on the "Loop". Hope to meet you when you are back in Tucson! Keep up the great work.

[@jonmaloneycycling7593]

thank you

[@charlesmansplaining]

That guy that rode behind you at 5:21 had a triple up front with what looked to be 34 in the rear. That's my speed.🤣

[@jonmaloneycycling7593]

Lol

[@zaahierstanley955]

Sorry to hear that ... crashing is madness and so scary. I had 2 in 2020. Thanx for the vids that you always uploading

Hey Jon, I know you live your Shimano. DC Rainmaker just released important info that impacts your Hammerhead Karoo. You need to immediately turn off updates, or otherwise decline any offered updates on your Karoo. The problem is Shimano. They just ordered Hsmmerhead to remove all Shimano functionality (e.g. the Di2 features). Short story is that since SRAM bought Hammerhead, Shimano now decided they will not play nice and will not let anyone associated with their competitor have access to their products (Shimano still uses a proprietary form of the ANT+ protocol, so not being part of the 'open' standard, they can yank their support at anytime which they have. Karoo users now have to bear the burden of this. Anyway, this makes my choice between EKAR or GRX for my upcoming gravel build that much simpler. They can go pound sand.

[@jonmaloneycycling7593]

thank you for the comment, appreciate it

[@michaelstoecker4178]

Great comments - thanks, Jon.

[@jonmaloneycycling7593]

thanks for tuning in!

[@MrIanD1]

Have ultegra di2 11 speed. Ride on the flat roads of Aurora. So that is all I need. That said back in the day 8 speed was all you needed.

[@jonmaloneycycling7593]

Nice!!

[@snejok888]

only time it worth is when you got 1x12 sistem..i don't see a point of having 12 gears on the weal if you still have to carry around front derailleur and extra chainring

[@jonmaloneycycling7593]

true!

[@nickcamarillo8175]

Glad you’re okay and putting out these great videos. Why do you prefer the RSL 37’s over the Firecrest 303’s?

[@jonmaloneycycling7593]

Thanks so much man. I think they are better made and just feel faster to me. Just a feeling

[@salva.]

God info! Will check that Bike Calc tool. 🤙🏻

[@jonmaloneycycling7593]

Thanks for tuning in!

[@christopherbrown9618]

Great information! I’m thinking about changing my gearing on my Émonda and I’m trying to get some ideas on how I want to spec my new Madone. I was also thinking about going with a SRM power meter carbon and titanium crankset on the Madone and I’m curious of your thoughts on that compared to the Dura Ace crankset.

[@jonmaloneycycling7593]

Glad it was helpful!

[@jussa101]

I used to think sram was stupid for changing to a 48 upfront. But then I started looking at the data I spent over 95% of my time in the big ring 48/10-33. My other road bike has good old sprinter gearing I spend close to 50/50 in each ring. Yea the bigger gears are maybe more efficient but as soon as you drop into the smaller chainring you've lost the theoretical efficient gearing.

[@jonmaloneycycling7593]

thanks for sharing your perspective and experience. Appreciate it

[@thepatternforms859]

New shimano is 52/36 up front and 11-30 in the back on a cervelo p5

[@psps4550]

Bell is no use if people are not aware the surroundings, i usually need to shout loud ! Be Careful Watch out !

[@sanangelo7926]

Had a guy with noise canceling AirPod’s pull in front of me. No matter how loud I yelled helped. Dude didn’t have a helmet on and almost had a nice fall and had no idea how close he came to going down and cracking his head open.

[@jonmaloneycycling7593]

good point

[@timothymburton]

I have a 40x54. Love it!

[@jonmaloneycycling7593]

Nice!!

[@philippang07]

Jon, please check your ribs in an xray if the pain persists. Thank you for your vid. Keep safe.

[@jonmaloneycycling7593]

thank you!

[@0xjdion]

I just crashed after my second ride with my brand new high end bike too. I think I fracture a bone in my back. Stay safe man.

[@jonmaloneycycling7593]

stay safe as well!

[@einundsiebenziger5488]

So silly Shimano gets back to bigger chainrings. In the last two decades, gears became smaller for good reasons. So many cyclists finally got up the hills they never managed to before, and it even got many people into cycling because the smaller gears meant it does not require extreme fitness to ride up a hill comfortably at a decent speed. Now some nerd at Shimano comes up with "better drivetrain efficiency" and people are starting to fall for it, even though nobody ever blamed an "unefficient drivetrain" when the ride felt slow.

[@Steve-jo3cl]

EXACTLY !!!!! Why on earth a guy riding a 54/42 chainrings is giving gearing advice ....... If your worried about drivetrain efficiency on a road bike, you really need to be more worried about the grease in your bearings, CRAZY !!!

[@jonmaloneycycling7593]

Thanks man

[@craigferguson5976]

Hi Jon - great videos! On my second ride with DA9200 and have dropped the chain over the crank (outside) 5 times. I’ve adjusted the front and rear derailleur using the E-TUBE app. Thinking my chain is too long…thoughts?

[@jonmaloneycycling7593]

Thanks man!! Chain length could be an issue and I would re adjust your front derailleur

[@dmalaga7896]

Hello, Jon, how compare Mille GTO jersey to RS? Is same fit? Less breathable? The pockets I see bigger I think, Thanks. Great, great videos, regards from Spain

[@jonmaloneycycling7593]

Rs is more breathable for sure. GTO is better for all climates. It’s a great jersey but not worth the money IMO Thanks bro!!

[@sworks]

Hello Jon Question can I put a 12 speed dura ace crank with my SRAM red axs 12 speed ? I don’t like the look of the crankset red ?

[@enzosterckx4774]

what type bb you are using to fit the quarq dfour in the émonda?

[@jonmaloneycycling7593]

T47 Dub

[@ginomordocco4710]

Hey Jon, I have the new 12 speed Ultegra on the way. I am currently running Dura Ace 11 speed mechanical. From what I heard in this video I should be able to use my Dura Ace crank right?

[@cyclingfan7303]

Some of the pro teams were having a lot of drop chains because of it. Shimano clearly is stated they aren’t compatible.

[@jonmaloneycycling7593]

Yes you can use it

[@donwinston]

Can you change a Dura Ace 50-34 compact crank to a 52-36 or 53-39? Is everything the same except the rings?

[@einundsiebenziger5488]

Yes. Don't even need to lengthen the chain. Only a minor re-adjustment of the front derailleur is required.

[@jonmaloneycycling7593]

Yes exactly

[@nuttynut722]

clearly a DA shifter are more expensive than a rib bone

[@javil1803]

Thank you for the info. 😁

[@jonmaloneycycling7593]

thanks for tuning in!

[@openwheelracing88]

bike paths are so dangerous

[@jonmaloneycycling7593]

just have to be smart and aware out there

[@Steve-jo3cl]

Several World tour Teams fitted with Shimano have said the 11speed front chainrings are NOT compatible with the new 12 speed, Think I'll take their word on that matter !

[@jonmaloneycycling7593]

Nice. Happy riding!

[@sanangelo7926]

So I guess I am doing it wrong on my single speed……. 😀
