Hi All

Been considering buying a hub-geared bike until I read here and in Richard's 21st Century Bicycle book, that hub gear systems lose up to half the pedalling energy a rider puts out.

Anyone here who can compare notes? I'm not wedded to the idea of a hub-geared bike but that has turned me completely against the idea. Anyone seen a good article on the subject that I could read?

I think it depends on each of the different hub gears. If you've got money for an expensive rohloff hub, go for it. If your touring a lot, a high end hub gear would have some advantages in terms of being much less vulnerable to damage on the road and in transit. You can shift gears while stopping at traffic lights, your chain won't need replacing as much and is easier to clean. But for the money, i wouldn't go past a Deore/105 (or better than) Shimano derailleur setup.

Here's the information you're looking for.

In summary, the efficiency of hub gears is roughly equivalent to, or slightly less than, the efficiency of derailleurs.

Brilliiant stuff, this is exaclty what I wanted. What an amazing journal too!

After a few months on a fixie - i'd forget the gears altogether!!! all the advantages of the hub in terms of cleaning, and more efficient than derailleur (i guess??) I'm tempted to take one of the retired (geared) bikes off the wall and just check I'm not missing anything - oops - sold em/converted em all. darn.
Once you have the ratio sorted (42 X 16 for commute) you'll never look back.

I love my Shimano Nexus 8 speed (redline model) for commuting. Twist shift means super quick shifts 3 or 4 at a time while moving or stopped. Weather proof and no maintenance. Had mine for four years.
