I've been riding it like that for about 5 years without problems except when I need to sort out a puncture. But possibly I'm getting more punctures than I might have expected (even adjusted for the amount of blackthorn around here) </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18020&page=2#post-258510 Mon, 28 Aug 2017 13:12:24 +0000 neddie 258510@http://citycyclingedinburgh.info/bbpress/ <p>Based on my own experience, I would not use a 23-28 tube in 28 tyre except in an emergency. The tube gets extra stressed around the valve and can lead to early failure. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18020&page=2#post-258509 Mon, 28 Aug 2017 12:52:18 +0000 Darkerside 258509@http://citycyclingedinburgh.info/bbpress/ <p>Are there suspicious weld marks along some of the frame tubes?

Actually, that's another can of worms as it turns out my back brakes had sprung out of alignment and one of the pads is now very crookedly worn. Fortunately I never cycle much above a sedate amble so I'll probably get away with it. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18020&page=2#post-258459 Sun, 27 Aug 2017 20:23:18 +0000 hunnymonster 258459@http://citycyclingedinburgh.info/bbpress/ <p>700x18/28 tubes are definitely available (which would cover the needed 23 &amp; 28) - I have 2 on my bike right now...

That will leave me with a redundant lightly worn slime inner tube which may be a price worth paying not to have a bike with one schraeder and one presta valve. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18020&page=2#post-258444 Sun, 27 Aug 2017 18:38:42 +0000 chdot 258444@http://citycyclingedinburgh.info/bbpress/ <p><a href="http://www.sheldonbrown.com/tire-sizing.html" rel="nofollow">http://www.sheldonbrown.com/tire-sizing.html</a> </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18020&page=2#post-258443 Sun, 27 Aug 2017 18:19:17 +0000 gembo 258443@http://citycyclingedinburgh.info/bbpress/ <p>@sallyhinch, that can be a problem.</p> <p>You want an inner tube that has the same number on it as the tyre.

It just means that the inner tube that fits the wheel doesn't match the inner tube size written on the tyre. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18020#post-258439 Sun, 27 Aug 2017 17:25:42 +0000 hunnymonster 258439@http://citycyclingedinburgh.info/bbpress/ <p>If a 700x28 fits (and doesn't rub the frame) - it's not the wrong size and has been giving you a considerably more comfortable ride than a 23mm tyre.</p> <p>700C = nominal diameter of the wheel (including tyre)<br /> x28 = 28mm tyre width </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18020#post-258437 Sun, 27 Aug 2017 17:18:29 +0000 sallyhinch 258437@http://citycyclingedinburgh.info/bbpress/ <p>unfortunately there are only 3 bike shops in Dumfries so once I move to the third, I'll be stuck with them as they will have thoroughly poisoned my mind against the previous two. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18020#post-258436 Sun, 27 Aug 2017 17:15:10 +0000 I were right about that saddle 258436@http://citycyclingedinburgh.info/bbpress/ <p><em>the bike mechanic who likes to cast aspersions on the bodges perpetrated by my previous bike mechanic</em></p> <p>To be fair that covers all bike mechanics.

This was installed by the bike mechanic who likes to cast aspersions on the bodges perpetrated by my previous bike mechanic. </p> <p>On the plus side, I've now had lots of practice taking my back wheel on and off </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18020#post-257381 Wed, 16 Aug 2017 19:39:48 +0000 Frenchy 257381@http://citycyclingedinburgh.info/bbpress/ <p>EDIT: Wrang threed. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=18020#post-257373 Wed, 16 Aug 2017 18:10:16 +0000 I were right about that saddle 257373@http://citycyclingedinburgh.info/bbpress/ <p><em>I've just remembered why I hate bike maintenance.</em></p> <p>I love working on bikes and I've only ever killed one by clumsiness, though it hasn't actually died yet but it will and it will have been my fault though the person witnessing the death will think it was theirs.
