The Case of the Offset Derailleur

Now that I’ve knocked down the big sources of noise, I can hear the smaller ones.  Given the unexplained offset in the derailleur adjustment, it should come as no surprise that I was now contending with derailleur noise.

A Step Backward

According to the postal service my Alfine hub has been received by Shimano.  According to Shimano they’ll look at it within three to five days.  So I should have some sort of resolution soon.  Meanwhile I’m back using my old drivetrain, and it sucks.

The Trouble with Alfine

My precious Alfine hub will soon be at peace with its maker, but I’ve still got some healing to do.  My experience with Alfine has been a roller coaster ride that has left me wary of internally geared hubs.  Not to mention anxious, moody, and prone to sudden outbursts of sobbing.  Combined with my DualDrive and Sturmey-Archer experience I guess  you could say that I’m thrice bitten… fourfold shy?  I’ve lost count.  What follows is my therapy.

Gearing

It’s a fact that a typical ‘bent needs wider and lower gearing than a typical upright bike.  Just how much wider and lower is a subjective, sometimes technical, and oft’ debated topic that can make large chunks of time vanish.  I’ll try to keep this brief.  I use Gear Inches in the following discussion because it is commonly used in trike specifications and it provides a good way to make relative comparisons between drivetrains.  Consult a Gear Inch Calculator to see how Gear Inches translate into speed.
