My mtb seat post slides an annoying amount but its still handy to be able to adjust it depending on the terrain. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19134#post-291821 Fri, 21 Sep 2018 10:30:43 +0000 Klaxon 291821@http://citycyclingedinburgh.info/bbpress/ <p>I’ve had to adjust one quick release which had been creatively twisted by another user </p> <p>I’ve had no such problem with dropping seatposts, but have had one bike with a front wheel nut completely missing and one where the lock pod sounded like it was about to drop off at any moment </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19134#post-291816 Fri, 21 Sep 2018 10:22:32 +0000 Ed1 291816@http://citycyclingedinburgh.info/bbpress/ <p>I use Tacx Carbon Assembly Compound to stop seat slipping it works on all bikes my bike is steel and seat post alloy. It has never slipped since applied a little tacx. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19134#post-291793 Thu, 20 Sep 2018 23:47:35 +0000 davecykl 291793@http://citycyclingedinburgh.info/bbpress/ <p>@rbrtwtmn: Yes, the seat posts do have some grease applied, but it doesn't seem an excessive amount. Maybe after a couple of weeks' use the grease will have smeared itself thinly enough to be less of a problem?</p> <p>(One bike I tried, the seat post dropped almost immediately: I think in that case, the seat clamp perhaps wasn't screwed quite tightly enough to the top of the seat tube.) </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19134#post-291792 Thu, 20 Sep 2018 23:44:19 +0000 davecykl 291792@http://citycyclingedinburgh.info/bbpress/ <p>@Frenchy: It looks as though the clamp could maybe(?) be tightened slightly by screwing using an appropriately sized screwdriver or hex key, but that's still a faff and the average person is not likely to have a mini-tool on them.</p> <p>Otherwise, to unlock and lock the seat clamp, you just flip the quick release lever through more than 90˚. </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19134#post-291789 Thu, 20 Sep 2018 22:47:50 +0000 rbrtwtmn 291789@http://citycyclingedinburgh.info/bbpress/ <p>Have they put grease on the seat post? I know why someone might do this for a saddle fixed at a given height (to stop everything seizing over time) but when one is being adjusted regularly then grease is a real problem I think. At least that's been my experience. I've had to clean this off after someone else added it more than once - and I've never had one seize (even slightly) if it was occasionally adjusted (e.g. with children growing). </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19134#post-291782 Thu, 20 Sep 2018 19:52:14 +0000 davecykl 291782@http://citycyclingedinburgh.info/bbpress/ <p>I'm sure it can't be beyond the combined powers of cycling and engineering geekdom for someone to have invented a seat post clamp that locks shut extremely tight, so that the saddle remains at the height that you left it?</p> <p>It really is extremely frustrating to gradually realise that you are going slower and slower, and that your knees are getting relatively higher and higher (and sorer and sorer), and to have to stop to adjust the saddle.</p> <p>Similarly, the 3-speed gear range is rather limiting: anything more than a very very gentle hill is a bit of a slog, and, on the other hand, you top out far too soon on the flat. I think 5 gears with a wider range would have been better suited to Edinburgh terrain! </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19134#post-291780 Thu, 20 Sep 2018 19:41:37 +0000 Frenchy 291780@http://citycyclingedinburgh.info/bbpress/ <p>Interesting. The London ones have an adjustable screw to allow you to tighten the seatpost clamp, but I can't remember if the Edinburgh ones do.</p> <p>(Also, at least 36mph). </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=19134#post-291779 Thu, 20 Sep 2018 19:35:50 +0000 davecykl 291779@http://citycyclingedinburgh.info/bbpress/ <p>I say, I say, I say...</p> <p>How fast does a city hire bike go?</p> <p>...</p> <p>...about 1 mark per 10 minutes, in my experience.</p> <p>(The mark in question being one of the helpful size markings on the seat post. Every bike I have hired so far has had a gradual sinking feeling of around that rate, at least.) </p>
