[GCPerformance]

Just so you know, in the weighing part of the video, I weigh the 105 stuff first and then the ultegra version of it. just so there is no confusion. if you have any questions about the two groups, please do not hesitate to ask me.

This video convinced me to go with 105 DI2. After about 500 miles, I'm very happy

[timmoss]

very useful, and I agree this decided me to buy 105 - 239 g is a big gulp of water. $750. Having had both sets on recent bikes, I feel no difference in braking and I never use the top buttons so it was a no-brainer

[jamessankey]

This video will level you up in the YouTube bike community. Kudos. Keep them coming.

[gc_on_demand]

Thanks for doing this. Pretty sure a lot of people appreciate this helpful information in regards of which one to buy.

[LainOTN]

There are much bigger differences.
1 - Third button
2 - Brakes, Servo Wave is a BIG diference on Ultegra.
3 - Front shifting, is mindblowing on Ultegra
4 - Hyperglide+ cassete, that will be the biggest difference.

To optimize I will choose.
ultegra rings with 105 cranks :p
Calipers + shifters - Ultegra
Front Derreilur - Ultegra
Rear Derraileur - 105
Cassete - Ultegra (HG+)
Chain - Ultegra (HG+)
Rotors - Ultegra if you want to reduce weight, if not 105.

If I'd build new bike, I've built it on 105 groupset with Dura Ace cassette, Ultegra crankset, Ultegra rotors.

[benmayes]

I’ve not finished the video yet but this is the most honest piece of bike content I’ve see about these group sets

[qibble]

A 105 set with Ultegra shifters seems the way to go, especially it you'd like to use extra satellite buttons. The 105 cassette and those lockrings for the discs are a huge surprise weight wise imho, for opposite reasons. Thanks for pointing it out:)

[BreakawayB]

I’ve been debating between the two options, thanks for this video.

[reaodasdf]

i see myself riding my mechanical 105 (r7000) for many years to come

[huangcalvin]

Thank u for sharing these practicable information between these two Shimano group sets~

[TheCharnwoodCyclist]

One thing I would recommend for anyone considering 105 is upgrade the rotors, I had constant issues with warping which immediately went away after swapping to XTR.

[Mower]

The lockrings are different type so in reality cannot compare them (105 are outer/external and ultegra inner/internal) Outer is always heavier. Some hubs can only accept outer so it also depends on your wheelset which one to choose.

[TheJohnTse]

thank you so much for the comparison video! Very details and good recommendation

[marklohnes]

Over the years, I have found that the main differences btw 105 and Ultegra and D/A out side of obvious price and weight is fit and finish, precision and longevity. This is particularly apparent in the mechanical shifting of 11 speed variants of the previous gen. Granted this is Di2…. The higher the group level the nicer the finish, the less slop and tolerances, and better durability over long term. You are absolutely correct that functionality is no different, but there is a marked difference in feel to how the Ultegra performs compared to 105, much less btw Ultegra and D/A…a case of splitting hairs outside of cost. Just my opinion…35 years of riding with Cat1/2 experience in my youthful days.

[RonBalone]

Background music is pretty noticeable. I would considering lowering the volume of that when you're talking.

[traversecitysufferclub]

Yeah I would totally do the 105 group, but upgrade the shifters so I can get the extra buttons. Maybe upgrade the chain and lock rings :)

[jerzyhorczyk]

Now let’s talk about the materials and breaking performance 👌

[rivnuts]

I really appreciate your attention to value and sharing that information with us.
