I think, on reflection, I'll stick to universal 3/32 for the reasons you mentioned above; indeed, the knackered (alloy) chainring has seen consistent abuse for several before giving up the ghost entirely (multiple tooth loss), so if that's what I get for using 3/32 stuff, I'm happy. </p> <p>Thanks again. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=12712#post-151396 Thu, 01 May 2014 15:47:04 +0000 MediumDave 151396@http://citycyclingedinburgh.info/bbpress/ <p>The first 2 chainrings on my current fixie were alloy (one Bontrager, one no-name thing) and were considerably less resilient than the steel Dura-Ace sprocket. I have not yet killed the steel surly chainring that's on there at the moment (2 years and counting). At a cursory glance, it's all wearing pretty well. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=12712#post-151286 Thu, 01 May 2014 11:14:49 +0000 DaveC 151286@http://citycyclingedinburgh.info/bbpress/ <p>From a wear pov, wouldn't the rear cog wear out before the front as it has less teeth and therefore will see more wear than the front?</p> <p>Can't comment on the chain, as I'm not a fixie fan (though never ridden one) </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=12712#post-151285 Thu, 01 May 2014 10:56:28 +0000 MediumDave 151285@http://citycyclingedinburgh.info/bbpress/ <p>It worked when I did this on my first fixie which was a proper pigeon machine. However make sure that your chainline is dead right as the 1/8 chain (or at least the one I was using) was very stiff laterally and would not tolerate even the slightest misalignment. </p> <p>I went back to 3/32 as it's so much easier when one can get spares for most of the drivetrain from a random LBS. I don't find that the 3/32 parts are wearing out sufficiently quickly for the vaunted extra lifespan of 1/8 to be useful to me. </p> <p>Mind you I tend to ride the drivetrain on my fixie to destruction and beyond rather and faff about measuring chain wear etc so your YMMV. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=12712#post-151184 Wed, 30 Apr 2014 16:36:01 +0000 skinnypins 151184@http://citycyclingedinburgh.info/bbpress/ <p>Hello,</p> <p>I'm replacing the chainring on my fixed gear commute bike, and plan to replace the cog and chain too so everything wears from a similar point. Up to now, I've been using 3/32" components, and I already have a replacement 3/32" chainring. </p> <p>However, I found an unused 1/8" cog in my bag of random bike bits, and in the interests of saving a few quid, I was toying with the idea of simply using a 1/8" chain. A cursory Google search seems to imply this will be okay, but I was curious if anyone here has experience using a wider chain on a narrow chainring, and if everything worked as it should? Thanks! </p>
