So does it definitely take 8 clicks to move from one end to the other? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19673#post-309156 Thu, 20 Jun 2019 23:02:19 +0000 neddie 309156@http://citycyclingedinburgh.info/bbpress/ <p>Thanks for all the helpful responses so far. </p> <p>Just checked the shifters and they have “Shimano Sora 9-speed” written on them. </p> <p>The mystery deepens... </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19673#post-309110 Thu, 20 Jun 2019 08:07:59 +0000 ejstubbs 309110@http://citycyclingedinburgh.info/bbpress/ <p>Possible that the shifters in question are available in versions which are compatible with either, and the wrong one was ordered/sent? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19673#post-309106 Thu, 20 Jun 2019 07:08:15 +0000 Cyclops 309106@http://citycyclingedinburgh.info/bbpress/ <p>There's no such thing as indexed shifters that are compatible with both 9 and 10 speed. Shifters will either be 9 OR 10 spd and it sounds like you've been sold the latter. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19673#post-309103 Wed, 19 Jun 2019 22:16:31 +0000 ejstubbs 309103@http://citycyclingedinburgh.info/bbpress/ <p>@Murun Buchstansangur: That's about chain compatibility with chainrings, though. It's not got a lot to do with whether neddie's shifters will work with his cassette.</p> <p>@neddie: What is the Shimano part number of the shifters you have bought? It'll be on e the nice blue packaging.</p> <p>SJS are usually pretty good at Shimano parts. It might be worth giving them a call to check whether the shifters you've bought are compatible with the cassette. If not then, under the <a href="https://www.which.co.uk/consumer-rights/regulation/consumer-contracts-regulations">Consumer Contracts Regulations</a>, you have 14 days from receipt of the items to inform the seller that you wish to return them. I suspect that SJS would be inclined to help you get any error rectified anyway, rather than you having to invoike your legal rights. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19673#post-309092 Wed, 19 Jun 2019 17:47:10 +0000 Murun Buchstansangur 309092@http://citycyclingedinburgh.info/bbpress/ <p>@neddie</p> <p>Sheldon again:</p> <p>"Chainrings/Cranks<br /> Old Chainrings, New Chains</p> <p>There is a lot of confusion about the compatibility of narrow 9- and 10-speed chains with older cranksets. Shimano says you should replace the inner chainring(s) with specially designated 9- or 10-speed ones, but then they're all too eager to sell you stuff, whether you need it or not.<br /> These chainrings have the teeth slightly farther to the right than the older chainrings to work a little better with the narrower chains. There is no difference whatever in the crank spiders.</p> <p>The manufacturers also are concerned about clueless users. The worst-case scenario is that you will be riding along with the bike in its highest gear (large front, small rear) and then for some bizarre reason shift down in front before downshifting in the back. (There is no shift pattern in which it is reasonable to shift in this sequence.) [Not with a 9- or 10-speed cassette, to be sure -- John Allen] If you do shift this way, there's a small chance that the chain might "skate" over the edges of the teeth for maybe half a turn.</p> <p>In practice this "problem" almost never materializes. Many, many cyclists are using 9- and 10-speed chains with older cranksets and having no problems whatever."</p> <p><a href="https://www.sheldonbrown.com/speeds.html#chainrings" rel="nofollow">https://www.sheldonbrown.com/speeds.html#chainrings</a></p> <p>YMMV </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19673#post-309090 Wed, 19 Jun 2019 17:28:37 +0000 neddie 309090@http://citycyclingedinburgh.info/bbpress/ <p>@Muran,</p> <p>I think (?) the front chainrings are 9-speed only</p> <p>I guess I should now go away and find out what parts I actually bought! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19673#post-309082 Wed, 19 Jun 2019 15:27:26 +0000 Murun Buchstansangur 309082@http://citycyclingedinburgh.info/bbpress/ <p>More on that alternate cable routing here:</p> <p><a href="https://www.sheldonbrown.com/drivetrain-mixing.shtml#alternate" rel="nofollow">https://www.sheldonbrown.com/drivetrain-mixing.shtml#alternate</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19673#post-309080 Wed, 19 Jun 2019 14:56:11 +0000 Baldcyclist 309080@http://citycyclingedinburgh.info/bbpress/ <p>I might be inclined to whine at the shop, and ask for discount on components for your trouble, or warn them it's used and on the way back because it was mis-sold. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19673#post-309078 Wed, 19 Jun 2019 14:43:35 +0000 Murun Buchstansangur 309078@http://citycyclingedinburgh.info/bbpress/ <p>Would it be ££ to upgrade to 10sp?

The indexing doesn't seems to work properly - usable, but it means fiddling the levers up/down sometimes to stay in the gear you want. Checking the Shimano website direct seems to indicate they are possibly 10-speed only.</p> <p>So have I been mis-sold a duffer, or can they be adjusted to index only 9 gears?</p> <p>If that can't be done, should I upgrade everything else to 10-speed (££), or change the levers (£££), or just tolerate the misalignment? </p>
