My list of debts to you is growing. I'll contact you later. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9594#post-102436 Fri, 01 Mar 2013 11:10:44 +0000 kaputnik 102436@http://citycyclingedinburgh.info/bbpress/ <p>if you were being pedantic, you could swap out the 9 speed jockey wheels on a 9-speed derailleur for ones that are 8-speed width, but I don't really think this would achieve that much. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9594#post-102432 Fri, 01 Mar 2013 10:50:24 +0000 Cyclingmollie 102432@http://citycyclingedinburgh.info/bbpress/ <p>I've a Sora 8 speed rear mech, latest type that you can have for nothing. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9594#post-102431 Fri, 01 Mar 2013 10:49:54 +0000 wingpig 102431@http://citycyclingedinburgh.info/bbpress/ <p>A 9 or 10 would work fine, providing the cage/jockey wheel axles is/are wide enough for the chain. I had a 105 rear mech working happily with my 8-speed cassette for over a year until half an hour ago, when it jumped into the spokes. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9594#post-102430 Fri, 01 Mar 2013 10:41:20 +0000 DaveC 102430@http://citycyclingedinburgh.info/bbpress/ <p>I think you can fit any shimano derailleur. I'd personally go with a straight swap replacement, and did on my Dawes recently. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9594#post-102426 Fri, 01 Mar 2013 10:29:03 +0000 amir 102426@http://citycyclingedinburgh.info/bbpress/ <p>I currently have Shimano Sora 8 speed system on my regular commute. I want to replace the rear derailleur - should I just buy a shimano 2300 as a more or less direct 8 speed replacement or could I equally get a 9 or 10 speed one that would work well (they are similar prices and easier to get)? </p>
