Back in the 1970s, an acquaintance told me sad tale. This guy was a pretty avid racer and had just taken delivery of a new custom bike with top tier equipment. A friendly guy at a race was praising it highly, admiring many of its features. After conversing a while, he asked the owner if he could briefly try it out. The owner said sure. The friendly guy got on the bike, rode maybe 20 yards, turned around and waved, then sprinted off. My guy never saw his bike again. Be careful out there. -- - 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. Good. We agree. And that's what everyone does. That benefit of brifters does exist, but it is negligible in almost all situations. Negligible to you -- not to me. Right. Different situations call for different priorities. But as I said, I think one touted advantage (shifting in traffic without moving one's hands) is negligible for most cyclists. I certainly never heard anyone complain about the problem in the era of downtube shifters. And brifters may now be necessary for racing, but very, very few cyclists race. We all place different a value on not having to reach down and shift. I'm tall. I like to climb out of the saddle, and am often being dragged around by other riders. Being able to shift from standing and being able to shift a lot without taking my hands off the bars is very valuable and not negligible to me, particularly gravel riding. Right, different priorities. But in all this discussion, please keep in mind that I do _not_ like downtube shifters. Remember? I'm the guy who said he converted his bikes to bar ends. For me, the final straw occurred while commuting to work. I got the bike, my first decent one, by trading. It was a bit small for me. One day I realized I was having to do a semi pushup each time I shifted. I got bar ends and was happy. IMO, no reasonable person would choose DT shifters for a new bike... OK, that's a little extreme, Jay. We can and should discuss advantages and disadvantages. But allow people their priorities, please! They are not unreasonable just because their criteria don't match yours. Also, the crushing possibility of component failure is not eliminated by using classic equipment. Of course! That's especially true if a person chooses lightweight classic equipment. But please note, I was also emphasizing repairability on the road. My only near-disable incident happened while climbing a monstrously steep hill just north of the Ohio River. Nearing the top, I tried to shift into my biggest rear cog and my cable snapped at the bar end shifter. I actually had a spare cable, but it was too short. (My cables run under the bar tape and my bike has a long wheelbase.) I ended up tying the new cable (fed into the shifter end) to the old cable (running from the derailleur end) to get enough length. Turns out tying cables together is very, very difficult - at least for me. I now make sure I have an extra long cable in that bike's bag. Also in the tandem's bag. Every other problem I've had on the road I've fixed reasonably quickly and ridden on. I value that highly. In all these years, the one thing I have never broken is a STI shifter. Hey, I can say the exact same thing! :-) But I've helped several friends get theirs shifting again. One was on a brand new bike, delivery taken the day before a week long tour. Not that I knew what was wrong or knew what I was doing. I just kept tugging on the cable while working the shifter, and eventually it came to life. The other was on a bike that had not been ridden for quite a while. Half an hour of flushing with various sprays got that one going. Of course, I've never broken a bar end shifter. But I have disassembled those for a thorough re-lube. They can be understood by a mechanic of average skill. -- - Frank Krygowski |

Because I can buy two different cassettes and customize them to get the EXACT gearing I want which is fairly close-spaced 7-speed with two larger bail-out gears. It's nice to have small jumps between gears so that I don't spin out when changing a gear, may cadence stays longer in the comfort zone and I still have to bail-out gears for when I'm bucking a strong headwind especially uphill. I looked at 10+ setups but won't get one of them do to the high expense of their cogsets and chains compared to 9-speed stuff. What you write makes sense on paper. Build a custom cogset with close spacing and two extra super low gears. But in reality with 10 speed and above I suspect, you can easily get the close spacing to stay in the optimal cadence plus have the right low gears too. 10-12 years ago I built up a new loaded touring bike. I went with 10 speed STI. 11-32 cassette that has perfectly good spacing plus big enough cogs too. Of course I added my own personally made crankset/chainrings to the bike that likely made the whole bike far far superior to anything you could buy off the shelf. 44-33-20 triple crankset using an ancient Shimano DX 110mm crankset with the inner ring at 74mm bcd. BUT I found an Avid tri-adaptor and converted the inner to a 58mm bcd ring able to take 20 tooth inner. Its almost the most perfect touring gearing on the face of the earth. I've never found 10 speed chains or cassettes to be hard to find or expensive. Today they might even be cheaper and easier to find than the older 9 speed. I think you set yourself back by going with sort of ancient 9 speed on your touring bike. Better to have 10 speed for a touring bike. OK, let me ask a question. Most people posting to this thread are saying, as Russell just did, that 10 cogs are better than 9. I'm also hearing the implication that 11 are better than 10. If 11 are better than 10 which are better than 9 which are better than 8 which are better than 7 which are better than 6 which are better than 5.... Where would you stop? By your own criteria, is there some number of cogs that would cause you to say "That's not needed. That number minus one is plenty"? Or is your ideal a "corncob," each cog one more tooth from - what? - 11 to 34 or more? (Bonus question: How many chainrings do you use?) -- - Frank Krygowski I have a 11 - 19 corncob on one of my bikes with a 28 - 38 - 48 triple crankset and I just love it on the rolling hills around here. The shifting on the hills is nice and gradual and my cadence stays very similar throughout the ride. No shifting into too low a gear because the needed/wanted jump isn't there. If I could do that sort of thing on my touring bike I'd be very tempted to do it. FOr me the limiting factor in more rear cogs isn't the number of them but the cost and the cost of new ones compared to 9-speed or 7-speed. Like I said, on my touring bike I have a 9-speed cassette set up with 7 fairly close gears and two bailout gears. Now if, and that's a very big if, I went to 11 or 12 cogs I could have closer jumps between any number of gears and still have a couple of gears set aside as bailout gears. that's my needs and wants and they are different to yours and some other people. That does not mean that people who want more than 7, 8 or 9 cogs should be mocked or derided for the choices they make for the type/types of riding they do. Cheers |

Changing gears ist easy, fast and works like a charm. Except when it it doesn't. Problem is, the construction is a mechanical nightmare. I bought it specifically because both cables (bowden cable?), both those for braking and those for changing gears are routed along the handle bar, so that there is enough space between the handles to moutn a large Ortlieb handlebar bag. Have look at https://pluspora.com/posts/296e60b0625701384a38005056264835, fifth picture or https://www.mystrobl.de/ws/pic/fahrrad/20200416/DSC01809.jpg Changing the inner cable is difficult, when one of the wires is already broken. Somehow I damaged an tiny spring while removing the old cable. In consequence, the whole expensive grip had to be replaced. .... 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. So do I. 197x ff: https://www.mystrobl.de/ws/pic/fahrrad/loire1.jpg 1996-2010: https://www.mystrobl.de/ws/pic/fahrrad/IMG-2461.JPG I prefer bar-end shifters, but I route the cables under the handlebar tape, which is not the default choice. I too ordered that custom made touring bicycle shown above with bar-end shifters, for being able to use it during winter with mittens. If memory serves me right, routing the cable along the handle bar under the tape was standard, I hadn't to ask for it. Much later, I had to change the handlebar after a fall. It wasn't broken, but noticeably bent, so I didn't take the risk. Changing was easy, after studying how it was mounted on the old handlebar. I don't, either. The problems I see are with the mechanical construction of the Brake/Shifter (brifter?) Shimano Ultegra ST-6700, caused by the necessity to route _two_ cables down to the handlebar, in so tiny space. Because of the small bending radius, a cable wires tends to break exactly where you need it last, in that tiny space inside the shifter, that is. The broken wire coils up inside and causes damage, when removing the broken cable. In my case, it damaged a tiny spring, one of two which are part of a ratched mechanism. After trying to find that spring and enough details about where and how it was mounted, I gave up and went on a hunt for a replacement part. Disassembling and reassembling a mechanical clock is easier. I still don't have an idea about how to remove a broken cable, safely. I guess, problems like these are the reason for tips like replacing the inner cables once or twice a year. I didn't have to to that for any of the shifters I used before. I always carried a few spare (inner) cables during the holiday rides and changed them on the fly, even on the road, when necessary. The owner of a bicycle shop, whom I consulted for getting a replacement shifter tried to convince me to use a an older shifter, he called them "Wäscheleinenschalthebel", clotheeslines shifter, because these didn't have this - to him - well known reliability problem. For me, this wasn't an option, because I very much rely on my large handle bar bag. My wife rides a Scott bicycle with the older 105 3x10 version of the group, which actually has these clotheslines. https://www.mystrobl.de/ws/pic/fahrrad/scott.png She actually would like to have a decent handlebar bag, too, but alas, that's not possible her. On the positive side, those shifters work flawlessly, so far. But I don't have any problem with excess lever force. I haven't, either. But I have a problem with equimpment which trades comfort against reliability. I'm sympathetic toward your problem of exotic parts and expensive replacements. Shimano groups aren't exotic, around here. Outside of cheap commonditiy bikes, it is difficult to buy a bike that isn't equippend with parts from the Shimano universe. 2 x 10 was standard in 2010. 3 x 10 might perhaps be considered unusual and exotic. Well, the part was the right shifter (10x), which is identical for 2x10 and 3x10. This might be the reason for the shortage. Perhaps Shimano produces these replacement parts by number, not by SKU, so an unexpected failure mode drained the stocked parts twice as fast. When I checked, the left levers where still available. 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. Sure. But buying simplicity comes with a price to, and often doesn't even work, when simple parts are even less available, in the middle of nowhere. Currently, I'm just watching the space. 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. In the remote village where they started, they learned one bike's rear derailleur did not work. One guy worked for hours with no success, no idea of what was wrong. Next day he made a phone call to a shop thousands of miles away and was given some tricks to try. Fortunately, one of them worked. If it hadn't, the trip might have been canceled. Well, shure, but that's not what we do. We stay in Europe for holiday riding. There is a lot of room not yet visited. My point was specifically the difference in expected reliability between this specific mechanical broken construction and product, and what I understand about how Di2 operates. Without having any real experience with Di2 so far, I nevertheless consider it more reliable. I stay away mostly because I don't have a need for it and because it is still exoctic and not stabilized as a product line. I doubt I'll tour the Andes, So do I. but I don't want to be even 20 miles from home and have problems like that. Well, I'm rarely more then a few kilometers away from a bus stop or a an opportunity to get a taxi. Thinking about it, the most remote situations where in the rural south of france, during day trips into the hills. We rarely did more than 70-80 km a day that way. In the worst case, a 40 km ride back to the house we rented would have done it. I really don't like to ride my wives bicycle, because it is smaller, but besides that, it is compatible, adjusting the saddle will do. That's an two hour ride to get back to the car, at max. Certainly not funny, but not the end of the world, either. Two bikes rarely break at the same time. I too like the ability to repair on the road. When riding to work, I often patched a tube on the road even when having a spare one available. That way, I _still_ have the spare. Why? Experience. Failures like these sometimes come in series. But I'm not going to pimp my bicycle into a kind of wartime vehicle, just for riding around town. :-) -- Wir danken für die Beachtung aller Sicherheitsbestimmungen |
