I keep thinking that I should build myself an IGH bike. Maybe even convert one of my recumbents to IGH. A couple of things are holding me back:

1. Inertia. I have a lot of experience with derailleur systems, I'm pretty good with them, and I don't have any objection to them. Every time that I starting thinking about IGH I ask myself what I have to gain and I don't have an answer.
2. I've had some bad experiences fixing flat tires on IGH bikes. It feels to me like converting a 5 or 10 minute roadside task into a 30 minute shop job.

I'm asking on 50+ because I'd like to hear 50+-type answers.
