+1 for 6800 cables deciding to explode in the shifter.

Wow, I’ve been running the same 7900 drivetrain for 20 years and never seen it. I do change out my cables every couple of years though. edit - strike that, I’ve been riding 7700 for 20 years (9 speed - not internally routed through the lever) Explains why I’ve never had it happen to me. However, I’ve never seen it happen to anyone else either…

I keep forgetting that I’m a tinker, for example my last gravel bike was a SS D/A bike with a goat link and a 11-36 cassette and a N/W chainring. I’ve never used a clutch until recently

Pretty sure Mark Beaumont rode across Africa with Di2!

[image] DarthShivious: Probably will in a couple years. I forget which article (cyclingtips?) mentioned limited availability at the end of October 2021, but when I asked my wrench he said next March. Looks like the quickest way to get the new 9200 is probably on a new bike :man_shrugging:

Can someone explain to me 2x12 with standard road / road compact cassette gearing? (please don’t bother) 12sp 11-12-13-14-15-16-17-19-21 -24 -27 -30 223gr (does the 16t gear really add any value??) 11sp 11-12-13-14-15 -17-19-21 -24 -27 -30 211gr 11sp 11-12-13-14-15 -17-19-21-23-25 -28 193gr 10sp 11-12-13-14-15 -17-19-21-23-25 175gr 10sp 11-12-13-14-15 -17-19-21 -24 -28 185gr I totally get 1x12 wide range, but it looks like 2x12 narrow range is completely unnecessary as implemented. I like gearing range, but the steps in the basic cassette lack value-add. I don’t see 1x12 helpful over 1x11 until you you’re at 11-34+. I just don’t see the need for 2x12sp unless you’re trying to run bigger rings on the front or a bigger chainring spread. Shiamano has the chainring spreads the same as prior and has dropped “full” 53/39t altogether (and consolidated their DA only pro gearing), leaving only “Mid-Compact” and “Compact”. Graphical Gear Calculator for Bicycles The bicycle gear calculator displays graphically the gearing of derailleur gears and gear hubs. It can be used to compare different setups to find the optimal gearing for all kinds of bicycles. vs a 10sp “straight deck” - you’re just peppering in unnecessary gears and yield two extra low gears in sum. If you look at 10sp 11-28, which is great to use, you really only get a 1/2 gear lower. Shimano basically added 40gr of cassette to their road cassette over 10sp and 11sp (not worth it for the 16t; but maybe for the 28t vs 30t) [image] 48t x 11-32t flat road cyclist… :slight_smile:

28 is the bailout gear! They’re putting you in 52/36 to begin with…. That’s the bailout gear! You’re always in bailout gear. 36/28 is double bailout. 36/30… how can you look a Belgian person in the eye? Or even you 19yr old self? :grin:

[image] ErickVH: SRAM has been trying to push it. The pro peloton has asked for special chainrings so they can largely ignore it. Yeah, and I think Shimano’s focus on pro road racers is actually limiting them. That’s why they don’t have a good do-it-all groupset like SRAM does, that’s why they were late to the gravel party and IMHO still haven’t cracked it. And that’s why they are still ignoring the 1x trend on road bikes. Shimano seems to be proud of offering 54/40 chain rings to the public, but nothing smaller than compact. No proper large range cassettes either. IMHO this is misguided and a mistake. How often do you want to pedal at speeds >65 km/h on public roads? (For the record, that’s the speed I spin out at with my 1x setup.

I actually would have liked to try that back then. I also would have liked to try the various semi-automatic shifting modes, too. But the loaner did not include any cables nor the Bluetooth module.
