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.

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.

@rioblast Жыл бұрын

Installed 105 di2 on my bike and upgraded the cassette to an ultegra for the hg+. Put the 105 cassette on my trainer. My thoughts on upgrading the front derailleur after looking at the data from my last 3h ride is 4 front shifts and 400 shifts rear. Modulated braking requires hills which I don’t have any. Only brake when stopping for traffic 😊

They make them by sandwiching a sheet of aluminium in between 2 sheets of stainless. Stainless is very sensitive to warping when heated and the spider supporting the rotor is very small compared to the RT-MT800 (XT) or Ultegra rotor. That makes the rotor less rigid. I prefer to use Shimano Deore Rt-64, they don't warp as much because they are solid stainless. I also found that they don't wear as fast as the ICE-tech.

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.

@l.d.t.6327 6 ай бұрын

as you said, granted this is DI2. I agree if this was mechanical, but with DI2 and brakes seemingly the same, there is no difference in feel of the shiters, the shifting itself and the braking. What may differ is speed of shifting and smoothness of shifting, but a big (the biggest) part of that is the cassette (whether it's hyperglide or not), and not so much the shifters and RD (in DI2).

The 105 to ultegra brake calipers have been the same or almost the same weight even on the previous groupsets. They perform exactly the same I've tried both. Putting lighter rotors and aftermarket cassettes with the 105 you'd get ultegra weight. Be careful mixing derailleurs as Shimano may have made 105 non interchangeable

@davidshepherd2927 Жыл бұрын

There is an optional 50/34 105 crank that is heavier and cheaper than the 105 hollowtech version. That may add up to 100 grams. When figuring the significance of a 2-300 gram difference, divide that amount by bike and rider weight. 200/80,000= 0.25% Totally insignificant. SRAM Force and Rival are both less expensive.

I have the pervious version of the ultegra, and those extra buttons aren't worth it. You can't really reach them on top.of the hoods without moving your hands. If they were on the side of the top "nubs" instead of right on top then you could squeeze it with your thumb and it'd be perfect. Until then I wouldn't bother, if I were buying right now I'd get the 105 levers.

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

is it possible to switch to either of these groupsets if one has a press-fit bottom bracket?

@yonglingng5640 Жыл бұрын

Shimano Hollowtech II has remained unchanged for years, so there's no reason it's impossible. What makes you think so? (don't worry, I'm not mad or anything, just curious)

@@yonglingng5640 I'm just not knowledgeable enough to know if the new group sets work with all types of bottom brackets. I know that the new group sets are being used with at least some bikes that have threaded bottom brackets.

@@joelchernov5342 They definitely will as Shimano hasn't changed the spindle's standard for years. For the 13 - 16 different BB standards for road bikes, there's always an option for Shimano Hollowtech II. If you take a look at any BB manufacturer's BB chart, you can see that Shimano has choices for all BB standards.

I read that ultegra Rotors dissipate heat better is this true? I climb a lot so better braking performance would be great when I hit the descends. All help is appreciated.

i am sure they do, I do not know by hoiw much and also these claims are from there own company so you have to take it with a grain of salt. But I know people say the cheaper rotors do heat up very quickly

@@GCPerformance18 I went with some galfer rotors because of the all steel construction. They're supposed to be better at heat dissipation than having an aluminum core like the shimano ones. We'll see how they work but I've read good reviews.
