CityCyclingEdinburgh was launched on the 27th of October 2009 as "an experiment".
IT’S TRUE!
CCE is 15years old!
Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.
I say, I say, I say...
How fast does a city hire bike go?
...
...about 1 mark per 10 minutes, in my experience.
(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.)
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.
(Also, at least 36mph).
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?
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.
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!
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).
@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.
Otherwise, to unlock and lock the seat clamp, you just flip the quick release lever through more than 90˚.
@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?
(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.)
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.
I’ve had to adjust one quick release which had been creatively twisted by another user
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
I use Tacx Carbon Assembly Compound
How permanent is that? My mtb seat post slides an annoying amount but its still handy to be able to adjust it depending on the terrain.
added some to my new seat tube after putting grease on it in error. Since used the tacx carbon my seat post has not sunk in 5 months.
