If we use the Sheldon Brown Gear Calculator set to metres development (although any other unit will work adequately), we see that the range for a 39-53 x 34-11 system is 2.5 to 10.4 metres developed per crank revolution, yielding an overall range of 416%. The widest range options from various companies are the Shimano Alfine 11 hub, which has a range of ...

I drive the same Rohloff for over 8 years and do not see an end of its lifetime. I cannot speak for other brands, but in all posts above the free-of-charge service by Rohloff, as part of their special corporate culture was not mentioned. Up to now, whenever there was a problem, the thing was being send to Rohloff and I had to pay nothing. That being said, ...

"Supposedly I just have to leave the shifter in position 7 and then assemble the outer part..." According to SRAM, the way to adjust it is to shift from 5th gear downward into 4th (which is the middle, 1:1 ratio gear) and then adjust the cable end until the clickbox marks are aligned. I have the similar P5 hub, and it shifts great for me when adjusted in ...

I'm very skeptical that an internal fault in the hub is causing the external mounting of it to loosen up... unless you are experiencing frequent total rear wheel lockup and skidding, maybe. I have a SRAM P5 hub that I built into an old mountain bike myself. Originally I ignored SRAM's torque instructions for the rear axle nuts and just tightened them by ...

It has to be somewhere you put your hands to lift the bike. Check out the wheel rims. They can collect all sorts of grime when you ride in the wet. Some of it will be ground rubber from your brakes, but most is road dirt. Motor vehicles drop oil and grease, and lots of rubber on the road. If you find that is the cause, the solution is to clean them after ...

What you know right now is that there's quite a lot of it and it's quite greasy. Which is useful, but not especially useful. One thing that occurs to me is to question whether someone else might have oiled the belt for you? Has it been in a shop, or do you have someone else in your house who maintains a bike? Is there a source of fumes where you store your ...

No, it is not a good idea. You'd be spending more than the bike is worth even for a basic internal gear hub (even assuming you got the wheel rebuilt for free using the existing rim and spokes, if possible), let alone buying a rear wheel with an IGH built in. You do need a chain tensioning pulley or horizontal dropouts, which while can be built more robustly ...

User6527 is wrong there. You can not use derailleur shifters due to the different cable length that is pulled or pushed to shift to another gear. You can not use other brands' shifters either for the same reason. The shifter you mention yourselve is available in black and silver, and both with and without integrated brake lever. There is also a 'cheaper' ...
