As there's no gears to change, deraileurs, etc. It doesn't get all gunked up like on my other bikes. I find that my hub geared folder chain doesn't get quite as mucky a chain, though it does get muckier than the single speed because I ride it in the rain.....all that road spray that comes up from the front wheel is full of crap. Even full mudguard with flap at the front doesn't stop all of it from spraying the bottom of the chain. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10022#post-108808 Fri, 26 Apr 2013 14:04:01 +0000 chdot 108808@http://citycyclingedinburgh.info/bbpress/ <p>"Don't they all just become black after a week anyway?"</p> <p>Only if you use them!! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10022#post-108806 Fri, 26 Apr 2013 14:00:28 +0000 Baldcyclist 108806@http://citycyclingedinburgh.info/bbpress/ <p>"<br /> I got a red one for my single speed.<br /> "</p> <p>Don't they all just become black after a week anyway? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10022#post-108800 Fri, 26 Apr 2013 13:45:26 +0000 crowriver 108800@http://citycyclingedinburgh.info/bbpress/ <p><em>8 speed or even old style 6 speed</p> <p>Aren't they the same thing?</em></p> <p>IIRC 8 speed is 3/32nds of an inch; 6 speed is 1/8th of an inch.

I got a red one for my single speed. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10022#post-108758 Fri, 26 Apr 2013 06:50:05 +0000 Dave 108758@http://citycyclingedinburgh.info/bbpress/ <p>@crowriver yes, the single speed / hub gear. It's a SRAM PC1 that's on it, so a 1/8th rather than 3/32nd chain.</p> <p>The internet says these chains are prone to snapping, so maybe I shouldn't be too surprised. However, they've been an OK choice since back when my only bike was fixed.</p> <p>It would be very hard to break the chain using the coaster brake IMO. It hardly takes any foot effort to lock the wheel (compared with the force you put in accelerating the bike) but needless to say, if you do break it or it comes unshipped, you're down to one brake. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10022#post-108751 Thu, 25 Apr 2013 23:30:04 +0000 Snowy 108751@http://citycyclingedinburgh.info/bbpress/ <p>Today fitted a sram PC991 to the cross bike. Previous chain had 3000+ miles on it. Left it far too long. Frankly amazed it's not skipping. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10022#post-108711 Thu, 25 Apr 2013 15:12:14 +0000 kaputnik 108711@http://citycyclingedinburgh.info/bbpress/ <p><em>8 speed or even old style 6 speed </em></p> <p>Aren't they the same thing? </p> <p>HG claims good for 6-8 speed anyway. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=10022#post-108707 Thu, 25 Apr 2013 14:52:48 +0000 crowriver 108707@http://citycyclingedinburgh.info/bbpress/ <p>Wait a sec, Dave, was this chain on the hub geared/coaster braked bike? Were you vraking with said coaster at the time it snapped?
