There may even be a screw-on freewheel with it. I say "may" as I might have consigned it to the Bike Station. </p> <p>What OLN distance are you after? Can't honestly remember what it is set up for but replacing the axle is a quick job for a bike shop. Requires a large hammer and the special punches to drive out the cartridge bearings without knackering them. Also nerves. Of steel. </p> <p>As to why I am not using the hub: I got Goldtecs instead. Not that you'd know due to the years of crusted chainsaw oil and road gunk... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17775#post-250983 Wed, 24 May 2017 08:56:21 +0000 Arellcat 250983@http://citycyclingedinburgh.info/bbpress/ <p><em>Slightly alarmed by the price of this. £109!!

Most of my commuting is East/West though, so not too bumpy. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17775#post-250960 Tue, 23 May 2017 19:25:51 +0000 gembo 250960@http://citycyclingedinburgh.info/bbpress/ <p>You could get a sturmey archer three speed fitted? Need spacers as I Think they are narrower than alfine? My view is single speed less kind on the knees but maybe depends on set up.? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=17775#post-250958 Tue, 23 May 2017 19:16:46 +0000 Greenroofer 250958@http://citycyclingedinburgh.info/bbpress/ <p>I have an aged Raleigh commuter bike with an Alfine hub and hydraulic brakes. I used to use it as a trailer tug and child tug, but now that I have an Elephant Bike* it's not needed for those duties. The bike has an eccentric bottom bracket for chain tensioning.</p> <p>I'm a bit fed up with with Alfine hub, as I hold it responsible for leaking oil onto the brakes. I'm wondering about turning the bike into a lowish geared singlespeed for winter use. The hub has over 12,000 miles in it, so doesn't owe me anything.</p> <p>So, is it practical to create a disc-braked singlespeed? If so, what hub would you recommend, and what gear ratio is best for everyday use in Edinburgh?</p> <p>*Did I say that I had an Elephant Bike? </p>
