best internal shifting hub?
What is the best internal shifting hub on these important points:
- reasonably lightweight compared to a road group - reliable operation - parts are available from the usual channels, not some guy working out of his garage. - has more than 3 speeds. |

The 14-speed Rohloff Speedhub should satisfy all these requirements (and many more), especially as you didn't specify any price limitations. See: http://www.rohloff.de/?p=PRODUKTE/SPEEDHUB It's about $800, available for example from Harris Cyclery. -as |

Depending on one's definition of "reasonably lightweight", there may not be much left. Rohloff adds about two pounds to the bike, is less efficient, makes considerable noise, and costs an arm and a leg. I just bought a second one for my hardtail. ----------------------- PeteCresswell |

How about for drop bars as well?

Last I heard, these bars were available through Rohloff's US office (contact info at www.rohloffusa.com). Or you can make your own twist grip: http://www.qnet.com/~crux/twist.html Tom Ace |

It seems like all gearhubs from 4 to 14 speeds weigh about the same 1.7 kg, give or take. With some you get a brake, making those effectively a little lighter. Only the Rohloff Speedhub gives step sizes between gears that compare to a road group. However, Sachs's and Shimano's 7 speed hubs give overall ranges similar to that of a road bike. (Road bike with 53/39 crank and 12-23 block: 260% Sachs/SRAM 7 speed: 303% Shimano Nexus 7-speed: 244%) If you need lots of gearing range and you can afford the Rohloff, then that's the one for you. I have had two, and I don't think anyone would find reason to switch back once accustomed to the Rohloff. If the price of the Rohloff is too much committment and/or you would like a drum brake, I recommend the Sachs/SRAM Spectro 7 speed. It is the most free-running gearhub (with more than 3 speeds) I have used, it seems quite durable, and the brake works consistently with minimal fade. Chalo Colina |

Chalo Colina I am interested in hearing a little more from Chalo on the Rohloff, and his reasons for buying them. (Chalo, aka Bluto is knowledgeable about machining, materials and manufacturing, and is a super-size kind of fellow.) Chalo, have you ever taken one apart, either out of curiosity or necessity? If so, did inspecting the innards lower or raise your initial evaluation? -- Ted Bennett Portland OR |

What about the durability of the Rohloff hub? I always heard about how
great Phil Wood hubs are. I was very disappointed with them and repeatedly trashed the insides (esp. where the pawls bite into). You would think with all the gears inside the Rohloff that something is likely to go in a relatively short period of time. I weigh over 200 pounds too. You can imagine that I'm seeing myself spend $800 and then thrash the gears and its junk on the side of the road. Then I'm opening the hub up trying to figure out where 100 gears fit in there. So you're saying that there is more friction? Is that when coasting? only when applying force to the cog? I think the shifter on drop bars is not ready for prime time. If only someone could come up with a decent shifter for drop bars. I like the concept though. If these kinds of hubs are very reliable, then they sound great. Are we saying that if we take a road bike with say Ultegra trip and STI and switch to Rohloff and no derailleurs that its going to be roughly 2 pounds heavier? I'm just trying to get a ballpark figure. I wish Shimano was more flexible with the road group components. As it is STI is not cyclocross friendly in terms of brakes.
