Read the manual, watched the video, seen the insides, but still can't quite shake off the niggling suspicion that voodoo is involved somewhere.</p> <p>Loved the guy's accent. Aboot! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17174#post-236805 Fri, 18 Nov 2016 10:39:36 +0000 Roibeard 236805@http://citycyclingedinburgh.info/bbpress/ <p>I'll add the <a href="https://www.rohloff.de/en/technology/speedhub/striptease/index.html">Rholoff </a>link, as it is extraordinary too.</p> <p>Robert </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17174#post-236803 Fri, 18 Nov 2016 10:29:51 +0000 neddie 236803@http://citycyclingedinburgh.info/bbpress/ <p>Pretty amazing piece of tech.</p> <p>Think I'll need to watch that video about 20 times before I've got it all though. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17174#post-236802 Fri, 18 Nov 2016 10:25:24 +0000 Arellcat 236802@http://citycyclingedinburgh.info/bbpress/ <p>One of the mechanics at Bikefix in London once disassembled a Rohloff hub gear to its component parts. Apparently it took him three weeks to put it back together. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17174#post-236784 Thu, 17 Nov 2016 23:28:25 +0000 Greenroofer 236784@http://citycyclingedinburgh.info/bbpress/ <p>If you've got an Alfine hub gear on a bike of yours, and you ever wondered how they work, here's the explanation.</p> <p><a href="https://www.youtube.com/watch?v=_Q5iEywX3yM" rel="nofollow">https://www.youtube.com/watch?v=_Q5iEywX3yM</a></p> <p>Having seen this, I am totally in awe of the Shimano engineers who designed it...</p> <p>...although I must confess still being slightly bamboozled by how it actually works. </p>
