That really didn't follow but I'm glad you've cleared that up. The inefficiency is about 8% I believe. I don't know of any A/B time trialling with both hub and derailleur so I don't really know about this point? Is there any information on this? I would be interested to read it. Efficiency isn't mute, I'm sure we all wish our bikes were more efficient when climbing that one in three hill.
> TLM is the lovely <girls name> so he's a she.
Well I apologise for not knowing. Are you recommending hubs because girls can't use tools?
> People who are comfortable with gear changing in cars still buy automatics for perfectly sound reasons. I suspect people said the same about the change from penny farthings.
The manual car to automatic is a perfectly valid analogy, and completely fits with your philosophy. The penny farthing analogy is pretty terrible and is a attempt to try show derailleurs as old fashioned.
Penny fathings were succeeded by faster, more efficient bikes with a lower center of gravity and bikes that had gears to get up hills. None of these apply to hubs vs derailleurs. Also the move from penny farthings was TO gears, more complexity(for the user), which is the opposite of what you're saying. Until people start racing with hubs (racing is usually where the cutting edge technology lies) then hubs won't be seen as some sort of natural progression to something better, while this remains the case and derailleurs still progress as they do then any attempt to imply that derailleurs are oldhat and obsolete is in vain.
> It interesting that I'm only suggesting to consider a hub geared bike an open opinion based upon reading and riding (Thorn hubs have been good for round the world cyclists, hire bikes are commonly being fitted with hub gears because of relibility, and the huge service interval).
Perfectly good argument. I would generally counter this to say the value more efficiency, reduced weight and cost and the capacity for maintenence without paying a mechanic outweighs this.
> It is others who react agressively to this suggestion. I'm perceiving a blind dogma from many that the "old system is best simply because it's familiar".
I hope im not reacting agressively. I think the 'old system' comment is countered above.
Now, if in future we take the derailleur technology as far as it can go and then another technology obsoletes it and is measurably better for the concerns of the person who wants to buy a new bike then I would recommend a bike with that technology. This here is not the case.
If tlm mentioned something above like:
1) "I don't have time for maintence and do not know much about bikes so I would prefer something that I can just take to a bike shop every couple of years and have it done."
2) "I often forget to change gear at lights and find
the wrong gear too often so I would like something simplier."
I would agree with you.
I'm not mocking these views and I believe the hub has a niche similar to the automatic car (really good example). But I can't recommend one to a experienced rider of at least 17 years who have neither mentioned 1) or 2). This is not to say don't try one. Do try one *if you want*.
