It appears that everything is subject to failure :-) That is very rare, more so than a derailer ripped away by a rock. Well, for me it's been rare, but it's happened maybe three times. It's why my touring bike has a spare rear derailleur cable in among its tools. The worst event was on an 80 mile, super-hilly ride I used to lead. My cable snapped at the shifter just as I was starting the toughest climb. I did make it to the top, then pulled over to change the cable. I found to my dismay that my spare cable was too short. (My touring bike has a long wheelbase, and I run the cables from the bar-end shifters under the handlebar tape. I need a cable longer than 73".) So I decided to run the new cable from the shifter, and tie it to the remains of the old cable, knotting it along the down tube. That's when I found that it's about impossible to tie two cables together using knots. I eventually did it, but my friends had to wait 20 minutes or more. -- - Frank Krygowski |

At one stage it came with a "too much force" caveat and I viewed it as unreliable off road(real offf road). https://www.rohloff.de/en/experience...pecifications/ 130NM. I think this is to discourage tandem use. Mines on a cargo bike, so far with no problems. All up wet weight likely 150kgs and add my shopping to that :-) |

On one of my bicycles I have a 9 gear 11 - 19 teeth corncob cluster on it that I made up for fun from some 9 speed cassettes plus one cog from an 8 speed cassette. It shifts just fine with the friction shifters I'm using on that bike. Cheers I went from an 8 speed triple on my Bianchi Volpe to a 10 speed double on my Spec Tarmac. The difference was amazing. g Of course the weight went from 30lbs to 18lbs and the bar end shifters went to Shimano 105 brifters and the steel frame to carbon and, and and ... Mostly kidding but unless you change the group on the same bike without changing anything else it would be difficult to determine the difference. I switched bikes from the Tarmac Elite to a Tarmac Pro with 11 speed double and I see a difference also but even then the Pro is 3 lbs lighter and had a 52/36 11T28 instead of the 53/39 12t28. Generally, I would say that people have different requirements. I understand that some people buy based purely on marketing but a lot of cyclists are interested in the actual performance of the bike. And you don't have to be a pro racer to appreciate that. |

Main thing is, with batteries the number of available shifts per charge is finite. I was told that front shifts are especially hard on the battery and on mountainous singletrack that's used a lot. Well, I don't have an electric shift but I have read that folks that use the Shimano electric shift have to recharge, or replace the battery every year or so, which doesn't sound like an impossibly frequent task. If I had north of $1k burning in my pocket I'd rather spend that on a Rohloff. That one allows shifts across the complete gear range at very low or zero speed which is very useful in MTB riding. To heck with the extra weight. Good Lord! You have been talking about retirement, you own two cars, You live in a gated community and can't afford a thousand dollars? Look at it as an investment, after all you could change the rear wheel when you change bikes. The other day I was reading, in another group, about a guy that was buying a cheap hand phone for a pre-teen kid and it was "only" $180. I had assumed that all you "round eyes" were rich. -- Cheers, John B. In what world do you get the right to tell someone else how to spend their money? You have to be one of the most contemptible people I've ever had the misfortune to communicate with. |
