We ship hard to find parts, tools and accessories all over the world. A report by Thorns designer and test pilotAndy Blance. It is a decade since Rohloff first introduced their revolutionary 1. I was interested in the hub at the time, but I didnt want to buy something which I felt may not work properly and which I knew I would never be able to mend. We were persuaded by some strong willed customers into building a few custom. Speedhubs and hearing some positive feedback from the happy. I decided to contact Rohloff myself I reasoned that, with the passing. Rohloff would have identified and cured any problems during this. What problems have you had and what is the service life I asked, getting straight to the point, after introducing myself. No joke, Andy, but we have never had a hub fail, so we cant tell you the service life, but some of our customers have covered 7. Carsten Geck. There followed more emails, my design for a frame was approved. This is equipped with an eccentric BB to adjust chain tension, whilst using socketed vertical drop outs, which we know produce the most reliable rear ends for touring bikes. We had more conversations about how low you could gear the hub, Rohloff have calculated that the maximum torque, that the hub will reliably withstand, is slightly more than could be produced by two world class athletes on a tandem using a 3. This is the lowest gearing that they will sanction which is equivalent to a 2. I use very low gears and I wanted even lower ones Whenever I get the opportunity, I like to travel on dirt roads, over high mountains, with medium weight camping and cooking kit and up to 1 weeks supply of food. I reasoned that, as I was certainly not a world class athlete, not particularly strong or heavy and there is only 1 of me that I should be able to use a lower gear than would be safe for the two world class athletes on their tandem Carsten agreed with me, but maintained that if I chose this route, it would be at my own riskno exceptions I decided that I would use 3. Rohloff would give warranty for I felt confident that I would never produce the level of pedal force of 1 elite athlete, even with an 1. I built 2 long wheelbase e.

I liked the Rohloff hub so much that my e. XXp has been joined by a lightweight, sporty bike with. Speedhub this is geared 3. What I liked about the Speedhub. Speedhub, it was originally built as an all season MTB hub, for use in Northern Europes extreme conditionsit is well sealed, all the internals run in an oil bath I like the fact that the indexing of the gears takes place inside the hub, this means that the twist grip, although beautifully made to enable easy replacement of the cables, is a low tech itemthere is little to go wrong with it unlike current derailleur shifters The twin cable system means that there are no return springs to fail, either in the shifter or the hub. I like the way that the next gear up or down is only a simple twist of the shifter away none of that changing up a chainring and down two sprockets. I love being able to change gear without pedalling, it is difficult to express how really useful this is. It is great not to have a derailleur hanging low down waiting to be knocked. The smaller chainring and sprocket and lack of rear derailleur means that the chain is less likely to cover your leg in black muck. I like the way Rohloff have engineered the sprocket to be double sidedwear it out and then turn it round and wear it out again, only the British, Scandinavians or the Germans would think to do this. I like the way the gears never jump or slipyou feel really confident pedalling, or changing gear, when out of the saddle I like the absolute silence of pedalling it, in gears 8 to 1. The War Report Cnn. Things I dislike about the Rohloff Speedhub. It would be too much to hope that there would be no dislikes, but they are few. It is a shame that the hub is only available in 3. I have been persuaded that 3. It is a pity that fitting the 2. I personally prefer swept back riser bars, with inboard mounted bar ends for touring and general cycling, but there are those who dont. I dont enjoy the noise in gears 7 to 1, especially the noise in gear 7but I can easily live with it, because it is the noise of precision parts rotating and meshing at speed, the hub does get quieter with the miles and I am in gears 8 to 1. I dont like the fact that you have to back off when changing between 7 and 8 and 8 and 7. If you dont back off, you will stay in the highest gear 1. I quizzed Rohloff about this and they said that it was because of a safety feature that they had engineered into the hub The Rohloff 1. Gear 7 is the top gear in the low ratio. Gear 8 is the bottom gear in the high ratio. To shift between them requires two separate things to happen, from 7 to 8 the hub needs to change from low ratio into highratio and from top gear into bottom gear, if Rohloff had attempted to make both things happen simultaneously, wear would have tended to make one shift happen before the otherif it changed to bottom gear first, then you would momentarily be in 1st gear bottom gear low ratio the pedals would fall away from you and you may have had an accident. So Rohloff engineered the shift to occur in two phases. On the way up the gears, it first changes into high ratio, then into bottom. And on the way down the gears, it first changes into top gear, then into low. The fail safe way it has been engineered, does mean you need to back. It is easy to know when. I dislike the weightIt does weigh a little more than the items it replaces. But to be fair to Rohloff, when you see a cut away drawing and you see. This is German engineering at its finestit. I am not going to cite the high cost as. Goodness only knows how many s worth of shifters, cassettes, derailleur, chains, chain rings and rear hubs. Rohloff Speedhub Or how.
