The new cassette went on very easily and I just nipped it tight ;-)</p> <p>The bike runs lovely now O:-) </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97323 Fri, 18 Jan 2013 15:20:13 +0000 crowriver 97323@http://citycyclingedinburgh.info/bbpress/ <p>It's the lockring you over tightened? With the right extractor hopefully souldn't be a big problem to remove. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97308 Fri, 18 Jan 2013 13:03:30 +0000 DaveC 97308@http://citycyclingedinburgh.info/bbpress/ <p>Damb, tightened the cassette nut instead of loosening, mistakenly thinking it was the old type (you can tell how long its been since I changed a cassette). Then bent the cheepo (aldi??) chain whip trying to loosen. The worn teeth mean the chain kept coming off so I taped the chain to the cassette to hold it on.</p> <p>Looking at new chain whips they all look a bit whimpy (but need to replace the borrowed one), and I have found an old flat bladed crow bar in my garage (left from previous owner) and a length of new unused chain, which I intend to make into a 'brute force' chain whip at the weekend. The one on the Youtube video (god those yanks are flippin egomaniacs) showed a 'rear brute force' chain whip.</p> <p>In the mean time I have contacted the local independant bike mech and he's going to undo the cassette (I expect more brute force required and some sort of professional Chain Whip??) so I can pop the new one on.</p> <p>[Glum] </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97153 Wed, 16 Jan 2013 23:34:50 +0000 DaveC 97153@http://citycyclingedinburgh.info/bbpress/ <p>Hmm all good info. I have thoroughly degreased washed and re oiled the chain, cassette and the derailuirs. There is a lot of play in the chain and just spinning it on the stand I can see the chain riding up the front chainring. I have a new spare chain but am reluctant to change just the chain as I have done this in the past and the result is worse than now with constant skipping on the rear cassette. Just waiting for Wiggle to deliver. Tempted to ride my Dawes instead but snow &amp; more ice is forcast. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97148 Wed, 16 Jan 2013 22:42:48 +0000 kaputnik 97148@http://citycyclingedinburgh.info/bbpress/ <p>Yes you won't get triple rings on a double (compact or standard). You may or may not need a new derailleur, some of the Shimano ones seem compatible with either, if you get the limit screws right. If it's the Hollowtech type of cranks, you'll need a whole new crankset basically (or perhaps it's possible to just buy the drive side crank and spider, as they both use the same non-drive side crank). </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97147 Wed, 16 Jan 2013 22:32:44 +0000 steveo 97147@http://citycyclingedinburgh.info/bbpress/ <p>Nah, if the spider is designed for a compact you'll not be able to put three on. New Tiagra chainsets are only 50-60 quid but you might have to replace your derailleurs as well. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97141 Wed, 16 Jan 2013 20:28:50 +0000 DaveC 97141@http://citycyclingedinburgh.info/bbpress/ <p>My STIs are triple so I won't need new ones thankfully. I do need to investigate putting new chainrings on the chainset to make it a triple. I'm sute though that the centre section won't allow it :-( </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97126 Wed, 16 Jan 2013 17:56:34 +0000 wingpig 97126@http://citycyclingedinburgh.info/bbpress/ <p>Last time I chewed up a Sora chainring with a worn chain I replaced the middle ring with a solid steel one from my old bike, which is still looking nicely fully-toothed whilst the current cassette (the second since the chainring-chewing) is starting to skip on particular sprockets. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97117 Wed, 16 Jan 2013 16:49:21 +0000 crowriver 97117@http://citycyclingedinburgh.info/bbpress/ <p><em>If you're just needing a new cassette can I recommend SRAM, they seem to be a big tougher and cheaper. </em></p> <p>Yes, I agree. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97116 Wed, 16 Jan 2013 16:41:41 +0000 Tom 97116@http://citycyclingedinburgh.info/bbpress/ <p>kaputnik: <em>"ultimately less hard wearing things"</em></p> <p>Dura Ace chain-rings used to be nickel plated, presumably to reduce wear. It comes off in tiny razor-like shards. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97108 Wed, 16 Jan 2013 15:28:43 +0000 kaputnik 97108@http://citycyclingedinburgh.info/bbpress/ <p>Joe in Bikeworks told me that the alloy composition changes on the chainrings as you move up a specification to make them lighter, replacing steel with lighter, but ultimately less hard wearing things.</p> <p>Shimano chainrings can be hugely confusing as the come in both A and B types (odd or even teeth numbers). Officialy you can't have an A ring with a B on the other, but it's nonsense and you can, it just makes the shifting slightly clunkier as the "hyperglide" ramps to shift the chain between the rings are slightly out of alignment.</p> <p>But then if you are buying an Ultegra chainring you're probably not looking for good commuting miles out of the thing. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97107 Wed, 16 Jan 2013 15:26:03 +0000 Baldcyclist 97107@http://citycyclingedinburgh.info/bbpress/ <p><em>I think I would have the 4603 (triple) but I need to see if I can replace just the chainrings instead of the whole chainset.</em></p> <p>You would need to replace the chainset, including spider, and your shifters. A double shifter won't work with a tripple spider, the indexing is different. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97099 Wed, 16 Jan 2013 14:44:12 +0000 DaveC 97099@http://citycyclingedinburgh.info/bbpress/ <p>Cheers Steveo, I found by opening multiple pages on the Schimano website I can flick betwee the models. I think I would have the 4603 (triple) but I need to see if I can replace just the chainrings instead of the whole chainset.</p> <p>@Mark, I have arranged to corrow a coupple of items from Gavin in Dalgety Bay, but thanks for the offer, thats is very much appreciated.</p> <p>I have ordered new chain and cassette, and hope to change them over at the weekend or after the parts arrive. I hadn't considered changing the components until after the winter, but even so cycling is a pain with the current drivetrain as it just jumps at the most difficult points, like accelerating from traffic lights etc... in traffic. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97091 Wed, 16 Jan 2013 14:20:09 +0000 Arellcat 97091@http://citycyclingedinburgh.info/bbpress/ <p>BikeFan mentioned Shimano groupsets and inter-component compatibility here:</p> <p><a href="http://citycyclingedinburgh.info/bbpress/topic.php?id=7132" rel="nofollow">http://citycyclingedinburgh.info/bbpress/topic.php?id=7132</a></p> <p>linking to <a href="http://www.celebrazio.net/bicycling/shimano_compatibility.html">Bicycling - Shimano Road Bike Parts Compatibility</a>.</p> <p>The gold standard used to be the ADFC Fachausschuss Technik page, <a href="http://www.fa-technik.adfc.de/Hersteller/index.html">Herstellerinfos</a> but it only goes up to the 2006 model year.</p> <p>But BikeFan's link is based upon scrutiny of Shimano's own technical documents:</p> <p><a href="http://techdocs.shimano.com/techdocs/index.jsp" rel="nofollow">http://techdocs.shimano.com/techdocs/index.jsp</a></p> <p>in which components are listed with part numbers and compatibility; the documents beginning with "SI" are the gatefold service instructions we all known and love and rarely read.</p> <p>Very loosely, HG70 and above is preferable for quality of performance, weight, and corrosion resistance. In groupsettery, I would go for 105 and Ultegra, or SLX and XT. For chains I've been very happy with the performance of Sram's bog standard PC951 for 9 speed. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97089 Wed, 16 Jan 2013 14:02:04 +0000 Baldcyclist 97089@http://citycyclingedinburgh.info/bbpress/ <p>I would buy (I actually might do on Friday) <a href="http://www.wiggle.co.uk/shimano-tiagra-4600-10-speed-cassette/" rel="nofollow">http://www.wiggle.co.uk/shimano-tiagra-4600-10-speed-cassette/</a> in the 12-30 variety for my bike, similarly specced to yours.</p> <p>I recently replaced my chain with this 105 one: <a href="http://www.wiggle.co.uk/shimano-105-cn-5701-10-speed-chain/" rel="nofollow">http://www.wiggle.co.uk/shimano-105-cn-5701-10-speed-chain/</a> , it works fine but I should probably have done both cassette and chain at same time. Thought I woud let the cassette get trashed over winter.</p> <p>£37 for the two, should keep you going for the next 6 months or so....</p> <p>Oh, EDIT. If you need chain splitter / cassette remover etc, I have the various bits and bobs required to complete such a job with only minimal blood loss. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97087 Wed, 16 Jan 2013 14:00:33 +0000 steveo 97087@http://citycyclingedinburgh.info/bbpress/ <p>If you're just needing a new cassette can I recommend SRAM, they seem to be a big tougher and cheaper. I got about 2 years out of one with fairly big mileage and replacing a couple of chains.</p> <p>PG950 or PG970 not much between them, just a little weight and cash. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97084 Wed, 16 Jan 2013 13:51:26 +0000 steveo 97084@http://citycyclingedinburgh.info/bbpress/ <p>The group set loosely defines the quality band then there will be a product number which slots into this band. Your example of 4600 is chainsets I think. 46* is the quality band Tiagra, then 4603 is triple 4600 is the "normal" double and 4660 are compacts. I think. </p> <p><a href="http://en.wikipedia.org/wiki/Shimano#Road_groupsets" rel="nofollow">http://en.wikipedia.org/wiki/Shimano#Road_groupsets</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=9288#post-97083 Wed, 16 Jan 2013 13:43:10 +0000 DaveC 97083@http://citycyclingedinburgh.info/bbpress/ <p>Does anyone have alink to a guide to Schimano compnents as a comparison of their ranges please?</p> <p>Looking at new cassettes for my CX / winter commuter, I saw HG40 HG50, HG70-C???? etc... I also saw 4600, 4603, 4625 etc...</p> <p>I found via Sheldon's webpage that HG is Hyperglide - a shaping of the teeth to facilitate smoth gear changes, but was unable to find a guide with what each are and how they compare. Of course the price increases but as I like to buy 'middle of the range' components, I have no form of reference. I assume the more expensive the lighter the components, and a freind who broke two different rings on two different cassettes, it also appears the more expensive the kit, the lighter (and perhaps the less robust the components).</p> <p>Cheers,</p> <p>Dave C </p>
