|Internally geared hubs on modern road bikes?||niteschaos|

|Anyone who has had to build up a new rear wheel understands that getting the tension and alignment correct is a bit of a challenge. You also learn that if there were more distance between the collars on the hubs, you could build a laterally stiffer and stronger wheel. I thought the easiest way to to this with current technology was to take some gears off the casset and replace their equivalent with an internally geared hub. I'm sure their will be a wieght penalty, but for training, where durability is job one, you'd think it would work. Have like a 3-5 interally geared hub with 4-6 cogs on the casset would allow you to reduce the extreme dish on some current wheels. I wondered why you don't see this.
what do you guys think?

|I have a Bianchi Milano with a Shimano Nexus 6 speed internal geared hub. While that's fine for a cruiser, it would pretty much suck for serious riding. It's heavier; it's less efficient -- more internal friction; and it's noisy when not in a 1:1 ratio internally -- in other gears, it is always freewheeling or ratcheting inside, making a noticeable ticking sound.
This isn't to say that they could not be improved or that better ones are not out there. But, the current multi-geared systems of derailleurs and cassettes is extremely refined and hard to beat.

|You can still ride home without a derailleur as long as you still have one good cog left.|| |
