I am a software developer in Austin with extensive experience in Perl, Python, and C. I also have some lesser experience (but great interest in) Ocaml, Haskell, and Clojure.

Also, a hardcore commuter cyclist riding on a Tour Easy LWB recumbent and a Challenge Hurricane SWB recumbent. Been through a lot of gear over the years, discovering the hard way what works and what doesn't work since most bike shops don't actually know what's good for a commuter.

comment Trying to identify some very old Magura rim brakes
That is very much a relief! After Batman's response I took the bike to a Magura authorized shop, and it's still waiting there for the parts to come in. But if they really did keep the pads the same size, then I'll not have to do that once I learn how to work on hydraulics.

comment How do I take apart the axle and freehub on this bike
That seems about right. I notice the drag most when the whole system is put together. Spinning the front pedals when not under load should be trivial. In fact, they should actually continue spinning for a moment after they let go. Instead, it takes noticeable force, and they stop the instant I release them. Could be an issue in the bottom bracket, which I've not taken apart yet.

comment How do I take apart the axle and freehub on this bike
I went back to try it. It took more than a gentle tap... I actually applied a bit of force with the palm of my hand. It appears that the bearings are in semi-sealed cartridges and those cartridges are in a very, VERY tight fit.

comment How do I take apart the axle and freehub on this bike
I found that to be the case after I got stuff to pop out. What I'm not sure of now (and I haven't pulled off the freehub yet) is how to diagnose where all of the drag in the system is coming from. If it's spread around a lot of components, I could be in trouble, but I'm going to hope that examining and replacing worn components will solve all of it.

comment What do I need to research to switch to an internally geared hub?
Thanks for the technical details. I'll put all this to use while evaluating everything else. This is actually a level of bike modification I've never even approached before.

Fair point. My current racer recumbent was $1000 used.

I'm looking at these options specifically because the bike can't be modified to carry a front derailleur. Also, replacing the bike is a very expensive prospect, but one that I'll consider one day. I'm just looking for ways to add versatility without doing a full replacement.

comment Are bicycle rear racks and panniers suitable for cross-country riding?
Strosberg: thanks for that bit about the weight. Once that much weight is on the wheel, what would be the minimum width tire you would recommend in order to reduce the likelihood of a flat and to keep turning friction up? For instance, I'm on a pair of "slick" tires 35mm in width.

@Vorac: I am a very poor technical rider with little experience off-road. I was referring primarily to the difference between riding with a lot of gear and riding with very little gear, as I have experienced both. But I've not at all experienced 25lbs on my back vs. 25lbs mounted directly on the bike. I have only experienced the back pain of carrying an iBook and a change of clothes for 23 miles on my back.
