Really? At what point in time did my good friend, who has ridden her Trek since the 1980s, transition from "I just love this bike" to "I'm only doing this to be contrarian"? I use all my 11 cassette cogs. I could give one up, but why? My little lunch ride today was our standard loop of 16 miles and 1600 feet of climbing, full speed trying to keep up with my buddy. Except for the roll into town (to see the post-riot damage), everything was some degree of up or down. I shifted my way nicely up and down the cassette, enjoying each and every cog. I'm glad you love those cute little things, but: What did you have before the 11? Was it a 10? Was there really a time you said "Damn, I just hate that there are only ten cogs back there! When, oh when, will they invent an 11?" I doubt it. You probably told your ten cogs "You are all individuals, but I love each of you equally!" Seriously, I _never_ heard a cyclist complain about having the maximum number of cogs then on the market. But every time the industry did the N+1 move, there was quiet pride by the new owners who showed off their N+1 and slight envy by the guys who had only N. That was GM's 1960s tactic: "Wouldn't you rather have THIS year's model?" You have all these imagined scenarios. I don't know anyone who went out and bought 11sp simply because it became available. I was riding 10sp until my wife drove my Supersix under a low overhang when it was up on a roof rack. I also had 10sp on my CAAD 9, but that went off to Utah with my son. I know I had some eight speed shifters, and I think I put those on my sons old beater Windsor. My first STI bike was eight speed. I had 9 speed on my commuter, but I wanted to shift to hydraulic discs, so I went to 11sp. That was probably a mistake, and I should have found some 9speed hydraulic levers. Shimano does make them. So I have some redundant 9sp Tiagra levers sitting in a box downstairs. I had 7 speed on my old touring bike, which I did upgrade to eight speed STI because the bike was spec'd with bar-ends, which I hate. I gave that bike away. My tandem had seven or eight speed ERGO. I sold that. I have one-speed on my track bike. Anyway, the difference between 10 and 11 is, of course, one. I was riding 10sp 12-25/26 cassette, so I got a 28 on the 11sp. I like that 28 a lot these days. And I get to keep all my close range gears. What's not to like? Jay, I'm not saying masses of people threw away 10 speed bikes when 11s came out. But I am saying that if someone drove into a garage and wrecked an 8 speed they never complained about, they would buy a 9 speed to replace it. Repeat for 10, 11 and now perhaps 12. The important point is this: They were not unhappy with N gears until N+1 came out. But by golly, when the opportunity arose, they would find some way to justify N+1. They just went with the flow. It is easier today to get 11 speed stuff then 7 speed. Don't over analyze this. Lou I had to go with 11 speeds because getting 10 speed stuff was more expensive. Shimano isn't rebuildable so the 10 speed stuff is throw-away and the Campy parts to rebuild the levers was getting scarce. The one weakness of the Shimano Dura Ace 11 appears to be that it doesn't have a cable adjuster for the front derailleur and it is a real bear to get exactly the right cable tension. I don't get that. You can always put in an in-line barrel adjuster, no? Is there something about Dura Ace that prevents that? Is this a Shimano thing or a frame thing? My Trek Domane (originally Ultegra equipped) came stock with a barrel adjuster installed, since it has internal cabling and no "stops" where a more traditional adjuster could go. I've since converted it to Campy, pretty sure I still needed the barrel adjuster. Mark J. |

IMHO, these are much simpler machines than the purely mechanical 6703 parts. I'm currently not going to buy a new bike, but when I do, i'll consider a Di2 group, mostly because it's a much more robust construct. Some goodies like some automatic shifting are welcome too, though. But mainly, I'd really like to get rid of all those arkwardly routed cables, which break much to often. Interesting. I have always used large handlebar bags on (almost) all bikes. I prefer bar-end shifters, but I route the cables under the handlebar tape, which is not the default choice. But I don't have any problem with excess lever force. I'm sympathetic toward your problem of exotic parts and expensive replacements. I greatly prefer mechanical simplicity, and devices I can easily understand, strip and fix in the middle of nowhere. That still keeps me away from STI and di2. I recently read in _Bicycle Quarterly_ magazine about a bike tour in the remote Andes mountains. The tourists arrived with brand new bikes with di2 shifting.

There are places where you can't even flash the system software, a trivial setup step here. Note that I'm not dissing Di2 or any electronic system but there are places where it's not the best choice.

That stuff's pretty toxic, I believe. I'll admit I use it too, but only outdoors, and any rags used get quarantined outdoors too until they "outgas." Mark J. |

We got by with lots of booting, stitching and next day air shipping to a bike shop hundreds of miles away. But we should have carried a spare. -- - Frank Krygowski |

You draw strange conclusions. I never said or implied that. I only said that their are situations that it is not wise to shift with a DT shifter and it doesn't matter with a brifter. If you don't shift in that situation you are not in danger with DT shifter. You implied that people that are using brifters lack the riding skills to ride with only one hand on the handlebar. That is utter nonsense.. Everbody can ride with only one hand on the handlebar riding straight on good pavement. Lou |

For most riders, a telephone call to uber is sufficient for the rare chain problem or tire gash. Yes, and that's an illustration of different priorities. For me, "field serviceable" is important. And the only time I've used Uber is to get to or from a foreign airport. I'd hate to admit I needed it to finish a bike ride. -- - Frank Krygowski Field serviceable is highly overrated. Never had to call anyone to finish my ride not even when I knocked off my Di2 RD last winter. You are not the only one with 35 years of cycling history. Lou |

Anyone that rides downtube shifters or centerpull brakes in this day and age is either penniless or stupid or both. harumph. I have a Zeus Alfa centerpull on the front of my three speed to replace the Universal 61 destroyed when a rental truck ran me down. It's been no trouble at all since installed, 1998 or so. And you have wrists like Hercules trying to get a bike to stop. Even the change from the 2015 Campy brakes to the Skeleton brakes made a huge difference in hand pressure. There is a descent I did yesterday where the road comes around a turn and comes to a stop sign with about a 16% grade. Just the carbon rim pads make it almost impossible to stop at the stop sign until I changed over to Campy Carbon pads. It made such a huge difference in hand pressure I wonder what it is going to do to brake surface life. The aluminum rims I'm now using on the Madone are like a return to heaven. The cantilever Brakes I was using on my cyclocross bikes make stopping under difficult conditions scary until I changed to V-brakes. The very fact that so many people have changed to disk brakes is proof that people did NOT like not having effective brakes. Not having to worry about how effective your brakes are makes a huge difference in the way people ride. You would be wrong about that. One or two fingers are enough for most riding and it will lock up with moderate hand pressure (unlike the very cute but crappy performance Sturmey drum rear). Then again my front rim's a Red Label. On chinese carbon wonder wheels, all bets are off. On the gravel/cyclocross bikes I had with cantilever brakes and Campy aluminum rims you have to pull with all of your might to stop the bike returning on that particular downgrade stop sign. I would prey no cars were coming for that I could roll it. Installing V-brakes made all of the difference in the world. Classic cantilevers do require a bit more skill to set up and adjust correctly. I suspect that's the problem you had. We have classic cantilevers on our tandem, just like most tandems over the past 50 years or so. I've never, ever had a problem stopping or controlling speed. I did set them up with somewhat shorter transverse cables than normal, but not tremendously unusual. Try this: https://www.sheldonbrown.com/cantilever-geometry.html Your tandem probably had medium, designs much like Mountain bikes did, but CX bikes tend to have the wide, which have a low mechanical advantage and thus my experience was similar to Tom, I did mitigate by using some Kool Stop pads, which did mildly improve braking if at the cost of terrifying wear rate. The difference moving to mechanical disks which are far from top end, is light and day. In fairness would be fine (wide canti) on CX tracks or like, for Gravel tracks and even on tarmac on the steeper/bigger stuff lacks the bite. Roger Merriman |
