PBP03 was on a F&S Duomatic 2 speed coaster brake hub and there was undoubtedly more drag (viscous and rolling) than the derailleur gears I used for other PBPs. https://web.archive.org/web/20170608...l/bicycle/PBP/ mentions me in passing. That extra drag didn't matter though. I was riding for fun and deliberately aiming at a slower time than in '99. I had plenty of sleep and fun and got to chat with a bunch of interesting folk. Finishing PBP usually isn't something where saving an hour on the road makes a real difference. Getting the right amount of sleep and not faffing through the controls and out on the road makes the difference.

If a Rohloff is part of your dream bike, ride a Rohloff. If you want to maximise every marginal gain, then choose something else but be aware there are disadvantages to picking the lightest/ fastest whatever (e.g. how did that bottom bracket work out for you, GR62?). There are a thousand different approaches to PBP and every rider on the start line thinks that their approach is the right one and that everybody else has got it wrong.
