Just fit and forget. The wheel is a bit heavier but that doesn't really affect the ride that much. </p> <p>Downside of the Shimano dynamos are the modern versions are a complete swine to service. Happily they also seem to be rather well sealed so servicing isn't needed particularly often. The caveat is I don't do anything like your mileage so your experience may vary. </p> <p>The older NX-30s and NX-32s are easier to service but the seals disintegrate readily and getting new ones is now rather hard. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19350#post-298155 Fri, 21 Dec 2018 08:30:46 +0000 amir 298155@http://citycyclingedinburgh.info/bbpress/ <p>Thanks. I had a fanciful notion that I'd use a dynamo for winter commuting but take it off in the summer and at weekends. I'd also use it on my Audax bike for longer rides. But maybe not.</p> <p>Anyway, I'm going to fix up my LHT with dynamo lighting seeing as I have a 26 inch dynamo wheel to hand. Should give me a feel for it. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19350#post-298154 Fri, 21 Dec 2018 08:25:41 +0000 wingpig 298154@http://citycyclingedinburgh.info/bbpress/ <p>My rear lights are bolted to my mudguards, the wires wound round stays and frame and the front lights bolted to the fork crowns. Changing wheels would be easy but I like the lights to be fairly firmly fixed so that things don't get taken when locked up. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19350#post-298149 Thu, 20 Dec 2018 23:08:06 +0000 crowriver 298149@http://citycyclingedinburgh.info/bbpress/ <p>As others have said, depends on the cost of the components. If you've a solid axle bolt on Shimano dynamo wheel, maybe just pick up another for not a lot. As for the lights, probably too much hassle to swap: the cables and so on usually have to be lashed to the fork somehow even if the light is mounted on something easy to remove. If it';s bolted to the fork crown, maybe just forget it... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19350#post-298148 Thu, 20 Dec 2018 22:26:15 +0000 Greenroofer 298148@http://citycyclingedinburgh.info/bbpress/ <p>I went through a phase of swapping the dynamo- and disc-equipped wheel and light from my commuter bike onto my rim-braked road bike for long night rides. Swapping the wheel isn't a problem with a Shimano dynamo: they plug and unplug very easily and I could see the sense in using an expensive wheel on two bikes, but you'll quickly get fed up with re-wiring the light.</p> <p>Given that the light is £60-£90 (depending on fanciness), the question is how many times you want to put up with the faff before just paying to not have to do it. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19350#post-298146 Thu, 20 Dec 2018 21:35:40 +0000 steveo 298146@http://citycyclingedinburgh.info/bbpress/ <p>Disc or rim brakes? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19350#post-298145 Thu, 20 Dec 2018 21:06:54 +0000 chdot 298145@http://citycyclingedinburgh.info/bbpress/ <p><em>And</em> lights?</p> <p>Suppose it depends how wires are attached to bike(s). </p> <p>- and how lights are fixed. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19350#post-298144 Thu, 20 Dec 2018 20:57:18 +0000 amir 298144@http://citycyclingedinburgh.info/bbpress/ <p>Does it make any sense to share wheel and light between two bikes? How much of a pain is it to swap between the two bikes? </p>
