If you need to replace both cones I would recommend buying the right-hand set pre-attached to a new axle. There are useful videos about <a href="https://youtu.be/a9mAHypsjdo?list=FLoHbjqmOKaR1cuN-0_u55Rw">Shimano hub servicing</a> on YouTube. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16044#post-211586 Wed, 10 Feb 2016 11:36:22 +0000 ivangrozni 211586@http://citycyclingedinburgh.info/bbpress/ <p>I think the others have already answered your questions - but thought I'd chip in too. I would recommend disassembling the hub before you get replacement parts - means you can inspect for wear first - depending on what's worn it may be better to replace the entire hub.</p> <p>Keep an eye out for any spalls - (a worn/rough patch that should be localized to one spot if caught early - although I have seen spalls that have been almost fully circumferential). Anything that has a spall has already failed and should really be replaced. I've experienced a hub failure out on a ride (after ignoring signs of early wear on the raceways) and had a rather uncomfortable and crunchy cycle home - I would not recommend it!</p> <p>Rollers (balls) are easily replaceable, cones more difficult (try multiple shops - particularly those that recycle parts as Tractorfactory indicated), if the cup has wear then you need a new hub! </p> <p>For grease - the usual recommendation is trailer axle grease - you can get it from marine supply shops online. If memory serves me right it was a lot cheaper than bike-specific greases! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16044#post-211558 Wed, 10 Feb 2016 09:36:24 +0000 TractorFactory 211558@http://citycyclingedinburgh.info/bbpress/ <p>If cones are worn, I found trying to replace mine nippy as there doesn't seem to be any standard size. Had to trawl through 3 shops before I found one close enough to use as replacement.</p> <p>Cone spanners usually come in a set of 2 being 4 different sizes. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16044#post-211532 Tue, 09 Feb 2016 19:09:40 +0000 chdot 211532@http://citycyclingedinburgh.info/bbpress/ <p>If cones very worn, might get expensive. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16044#post-211530 Tue, 09 Feb 2016 18:59:53 +0000 ih 211530@http://citycyclingedinburgh.info/bbpress/ <p>Thank you chdot. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=16044#post-211527 Tue, 09 Feb 2016 18:45:51 +0000 chdot 211527@http://citycyclingedinburgh.info/bbpress/ <p>This will cover everything </p> <p><a href="http://www.ebay.co.uk/ulk/itm/121566953282" rel="nofollow">http://www.ebay.co.uk/ulk/itm/121566953282</a> </p> <p>If you were going to do this often(!)

Well, yes and no.</p> <p>First a cone spanner is essential but what size? Both hubs are Shimano Tiagra, front says HB4400 and rear FH4400i. Is it likely the cones are different sizes, the best I can do to measure them without calipers is, front 13mm and rear 14 or 15mm.</p> <p>Second, what bits of a hub can you obtain separately these days? Can you get ball bearings and those rubber grommet things that go on the outside to stop crud getting in?</p> <p>Many thanks.</p> <p>ih </p>
