Managed to get the one at the top embedded, though can't remember how...</p> <p>Apparently there was some swearing whilst some of the old bits were coming out. Old headset disappointingly thrown away without asking so I can't see how worn it was. I thought the old brake would have just enough reach but was going to get a new one anyway but was told the old one didn't have the drop.<br /> I can now get a full-length front mudguard. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-38905 Mon, 22 Aug 2011 10:03:03 +0000 wingpig 38905@http://citycyclingedinburgh.info/bbpress/ <p>BAGH.

Until ! traversing the dukes path in the trossachs, the steering went all funny,and i fell off ! Miss matched/fitted /lubed bearings had actually CUT the fork upper tube ( bit that goes into the bike frame )so it fell out !Spent a wee bit more time rebuilding the next time ! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-37754 Wed, 10 Aug 2011 16:26:43 +0000 Arellcat 37754@http://citycyclingedinburgh.info/bbpress/ <p><em>Ahead is threadless...

Either your lower headset cup is manky, or your headtube is rusting at the interface. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-37753 Wed, 10 Aug 2011 16:26:00 +0000 wingpig 37753@http://citycyclingedinburgh.info/bbpress/ <p>...and will therefore almost certainly be (1+(½*¼))", so the length of steerer is the only consideration if buying secondhand.

It's definitely not a threaded/quill as I had to find a stem extender for it shortly after buying it to make it rideable. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-37743 Wed, 10 Aug 2011 15:08:23 +0000 kaputnik 37743@http://citycyclingedinburgh.info/bbpress/ <p>Well it's either 1" or 1 1/8"...

Toothpaste is difficult to get back into the tube. How much do I need to undo at the top to get at the top of the steerer in order to be able to measure its diameter with my LIDL digital calliper in order to be certain that I'm looking for the right size of replacement fork (without disturbing the moving parts further down until I have to)? Just the stem? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-37717 Wed, 10 Aug 2011 12:27:46 +0000 kaputnik 37717@http://citycyclingedinburgh.info/bbpress/ <p>It sounds like when you open it up you will find a soup of badly damaged races, crushed ball bearings and rust - bound by a thin layer of perished grease.</p> <p>Bike Station have a headset remover, press, crown race setter and headtube reamer. That they have let me use before. They weren't on their official list of tools to hand out, but I asked for it by name and told the man behind the desk what it was for (he hadn't heard of one) and generally pretended I knew what I was doing (I did, but only from reading a book and looking at youtube clips) so they were happy to let me use it to get rid of me I think.</p> <p>You probably won't need the reamer. Be gentle removing the old crown race though or you might end up needing it.<br /> Race setter needed for making sure new crown race sitting level.<br /> Press needed for when it comes to installing top and bottom cups (both at same time, presses down the top one and up on the bottom one)<br /> You can get the old cups out (carefully) using a large flat-head screwdriver or a very solid piece of dowelling and tapping gently upwards on it, moving the point of impact round with every hit so as it comes out straight and true. Or you can get a special tool to do it.</p> <p>You have to buy a whole headset anyway, so it's not worth just replacing the top or bottom bit, just do the full lot. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-37702 Wed, 10 Aug 2011 11:30:27 +0000 wingpig 37702@http://citycyclingedinburgh.info/bbpress/ <p>I didn't have time last night to undo anything so tried to squidge some grease in through the gap between fork and headset, which mitigated the audible rumbling.</p> <p>At what stage is a headset press required in fiddling around with headsets? Just for the pressing-the-lower-race-onto-the-forks bit, if replacing the bottom bit of the headset or the entire headset or fork?</p> <p>I shall re-order the order in which I was going to do things and poke at it this evening, hopefully not losing any bearings or discovering that everything was being held together through corrosion-glue. I imagine measuring the steerer at the same time would then be useful when looking for replacement forks. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-37701 Wed, 10 Aug 2011 11:02:09 +0000 Stepdoh 37701@http://citycyclingedinburgh.info/bbpress/ <p>My 'rescued from under a tarp in someone's garden' bike frame was really rough around the headset but undoing, a good clean, a £2 bearing from TBW and some lithium grease and it was perfect again.</p> <p>Not even any indexing. YMMV though :) </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-37691 Wed, 10 Aug 2011 07:58:24 +0000 Nelly 37691@http://citycyclingedinburgh.info/bbpress/ <p>wingpig, I recently had a 1 inch headset and a bottom bracket replaced at TBW, total for parts and labour just under £60.</p> <p>I think the headset cost was £19.99, but cant remember the labour breakdown.</p> <p>Imagine other decent repair shops will be similarly priced. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-37690 Wed, 10 Aug 2011 01:14:01 +0000 Instography 37690@http://citycyclingedinburgh.info/bbpress/ <p>It sounds bone dry in there, like there's no grease at all in it. It would be worth opening it up to have a look at it. Various headsets on Wiggle for between £10 and £150 but about £25 seems usual and maybe half an hour to an hour to fit it. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-37686 Tue, 09 Aug 2011 21:48:23 +0000 Roibeard 37686@http://citycyclingedinburgh.info/bbpress/ <p>If it's just bearings, you may be able to replace these on their own, but worn bearings can damage their races requiring other bits to be replaced.</p> <p>Insert generic Sheldon Brown link here!</p> <p><a href="http://www.sheldonbrown.com/headsets.html" rel="nofollow">http://www.sheldonbrown.com/headsets.html</a></p> <p>Far be it for me to hinder your <strike>upgrade</strike> replacement plans though!</p> <p>Robert </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=3595#post-37681 Tue, 09 Aug 2011 21:11:19 +0000 wingpig 37681@http://citycyclingedinburgh.info/bbpress/ <p>After a little intermittent non-smoothness, I'm now getting a pronounced grinding noise out of my handlebars...</p> <p><a href="http://www.youtube.com/watch?v=9TON0raGWV0">...working on the embed thing...</a></p> <p>For some reason it's worse when turning right. I assume this is due to headset bearings disintegrating in some sort of unpleasant way but has anyone any prior experience with this sort of unpleasant noise, particularly with the sort (and whatever size it might be) of headset found in an EBC cheapo racer from 2006? What's the likely cost of a new headset (inc. labour)?</p> <p>The fork's not been looking particularly happy for a while so I intend to get that replaced at the same time. Is a replacement front fork (preferably steel, not carbon, preferably with mudguard/rack lugs, with modern 6/8mm caliper drillings) the sort of thing one might find in the Bike Station's parts sales? </p>
