Weight weenie question - weight difference between Shimano R8020 and R7020 Groupset
 

Quick question, hopefully easy. Is there somewhere that total group set weight is published and compared (versus adding up individual components, hoses, rotors, etc)? Wondering how much weight is truly saved by going with Shimano R8000 series disc group over R7000 disc. I'm switching from older Ultegra 6700 10 speed bike, so I'm thinking R7000 will already be a significant improvement in performance for me. Only reason for me to pay the extra for Ultegra would be purely aesthetic or weight savings. Thanks!

2478gr vs 2314gr so the difference is 164gr. With hoses, rotors etc. it'll be around 200gr.

I can tell you that the 105 7000 groupset is really good! I looked into the Ultegra also, but, after reading numerous reviews, decided on the 7000. GNC did a comprehensive review, on youtube, on both. For me, the $200+ difference was just not worth it for the weight difference. Other reviews also stated that the performance difference was negligible. In the end, only you can decide which is better for you. I was looking at pricing again recently, and it has really gone up for groupsets since I purchased back in May.

Hmmm, so about 1/2 pound (rounding up / 227g = 1/2 pound). And about 70g of that is made up between the crankset and the cassette. My new bike will come with a non-series crank that I will be swapping out. Looks like if I were to put an Ultegra Crank on (instead of 105 to match the rest of the group) and then swap to an Ultegra Cassette the next time I need to swap it out, the total weight difference between groups would only be around 1/4 pound at that point. Seems like a fair trade off for the cost. Thanks for the help!

Per the above, yeah, there's not a whole lot of difference in weight. A couple of the admittedly minor things that had me opt for Ultegra are the levers in particular - I don't wear gloves and I just like the feel of the composite levers vs alloy and they also have both free stroke adjustment and Servo Wave™ modulation. To be frank, I haven't yet adjusted the free stroke and all of my Shimano levers have had Servo Wave, so I couldn't tell you if it noticeable improvement, but FOMO and all that.

Oh, and Ultegra has more cafe stop cred. :p

I actually might go for Ultegra levers next time just because the carbon will chill my fingers less than alloy. Otherwise though, Ultegra seems super overrated.

Hadn’t really thought about that. My 6700 series have carbon levers, but where I live if it’s cool enough for my fingers to get chilled, I’m most likely in full fingered gloves by that time.

Yup, that's a big part of the reason that I said the composite levers feel better.

Ah... I was figuring you meant a more pleasant texture or finish.

I believe it is exactly one enema. :D :(
