The large 52 tooth chainring bite my eye all the time. Thanks for the nice idea here. I have a bench grinder so I am thinking to draw a circle on the large chainring and then slowing grind off these 52 teeth. loubapachehttps://www.blogger.com/profile/03546870254928426677noreply@blogger.comtag:blogger.com,1999:blog-6467858377106451384.post-40825724810339899632014-07-11T10:56:14.877-04:002014-07-11T10:56:14.877-04:00Hello, thanks for this post and comments!

I'm in the process of converting my Fuji 10 speed to a 5 speed and need to replace the old chain. I'm not sure if I should get a 10 speed chain or a 5 speed chain.

My old Dawes Galaxy tourer had ten speeds, but I've now got it in pieces pending a complete rebuild, and I plan to build it up as a 5-speed, with a single chainset I salvaged from an old shopper bike. Curiously, despite the shopper being fitted with a wide chain, the chainring has narrow teeth suitable for a derailleur chain. Maybe it was swapped at some point. It's cottered, but at least it'll give it the vintage look, in keeping with most of the other components. Five speeds should be more than adequate.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6467858377106451384.post-35908476028395353822013-10-24T07:28:01.174-04:002013-10-24T07:28:01.174-04:00Nice to see someone else championing 5 speed conve...Nice to see someone else championing 5 speed conversions. I impulse bought a customised cro-mo vintage racer a few months ago for next to nothing only to discover it was a 5 speed when I got it home (but still had the front derailleur attached). After removing the FD, it only took a couple of rides for me to realise that this sort of 5 speed set up is absolutely brilliant and was perfect for the city, I also love how it looks. I'm a total convert to the idea now and I'm about to customise my newest bike in the same way.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6467858377106451384.post-18442583817593550742013-08-10T21:54:01.450-04:002013-08-10T21:54:01.450-04:00My son just converted my 1972 Peugeot mixte to a 5...My son just converted my 1972 Peugeot mixte to a 5-speed and mentioned that I could place a bell where the front shifter used to be.

So much so, that I considered getting a light road frame with track drop-outs and installing the spare 5-speed SA hub that we have from Velouria's Pashley conversion.MDIhttps://www.blogger.com/profile/10810401918223629618noreply@blogger.comtag:blogger.com,1999:blog-6467858377106451384.post-67980545295873951522010-05-08T13:10:59.080-04:002010-05-08T13:10:59.080-04:00"Gear-hubs with a large number of speeds (Roh..."Gear-hubs with a large number of speeds (Rohloff SPEEDHUB excluded) are generally less efficient than a properly lubricated and adjusted derailleur system in new condition. Less sophisticated gear-hubs such as the 3-speed hub (with only a single epicyclic stage per high/low gear, and direct drive in second gear), when run-in and properly lubricated, are however able to match the efficiency of similar quality derailleur systems, because the chain is properly aligned and does not run through jockey wheels of a chain tensioner. In real-world conditions, derailleur gears are much more likely to suffer inefficiency due to poor lubrication, extreme wear, excess dirt or inaccurate adjustment." <br />Although the derailleur is indeed lighter and matches this type of bike better, I don't think it is more efficient. Also, a new SRAM or Sturmey archer 5 speed hub will have the same range of a 12-28 cassette, so there isnt't any considerable difference in range either. It is a matter of lightweight and historical matching vs simplicity and maintenance free option.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6467858377106451384.post-29603453032592779582010-05-08T11:02:30.273-04:002010-05-08T11:02:30.273-04:00To Sr. Helga and anyone else who wants a three spe...To Sr. Helga and anyone else who wants a three speed:<br /><br />The best way to get a three-speed is to find an old bike (e.g., Raleigh) that is already a three-speed and to make sure the gears work. I would convert a derailleur or single-speed to an internally-geared three-speed only with an older (up to the early 1970's or thereabouts) Sturmey Archer hub. Quality on the later ones declined precipitously because SA never replaced or retooled their machinery. It was so bad that when SunRace bought SA about ten years ago, they found that they had to scrap nearly all of the physical equipment.<br /><br />I don't recommend the Shimano three-speed hubs. (I'm not anti-Shimano, so this isn't a screed.) I have had two of their three-speed hubs, and neither lasted me more than a year of commuting. And, when I did ride them, I was breaking spokes about every 100 miles or so. Someone who knows about these things tells me that the reason I and others have broken a lot of spokes on the Shimano three-speeds is that the flanges are very thin.<br /><br />I have no expereince with the Sachs three-speed. But from what I hear, they're not as good as the older SAs.<br /><br />Anyway, Velouria, I really like your chainguard.Justine Valinottihttps://www.blogger.com/profile/10852069587181432102noreply@blogger.comtag:blogger.com,1999:blog-6467858377106451384.post-256695618282914702010-05-08T08:57:32.498-04:002010-05-08T08:57:32.498-04:00Interesting upgrades!

If you are making more than a few sparks at this point you a using too much pressure. You are only trying to remove a bazillionth of an inch at a time. After a few(or a bunch)times around the ring you should have a nice smooth, round edge. I like to finish the edge with a good mill file so that there are no tool marks and if it is steel I recommend some wax or paint to keep it from rusting.<br />Aluminum chainrings are the easiest to do because they are so soft but they are also the easiest to screw up for the same reason. If you have a hacksaw and a good file you dont need the powertools but you will need ALOT of time. If anyone wants this done I will cheerfully do it for them for the cost of a John Coltrane C.D. or two, see the photos above for an example of my work(dang, now my secret identity is revealed and I'm going to have to behave myself on this blog...).Spindizzynoreply@blogger.comtag:blogger.com,1999:blog-6467858377106451384.post-7834820297478298502010-05-08T00:33:47.756-04:002010-05-08T00:33:47.756-04:00That chainring looks fabulous, utterly natural.
