Any question answered...

Now ordered. Will report back from A&E.

Is there any difference at all between Sram Apex, Rival, and Force derailleurs (aside from colour and price?)

They're the same weight, so presumably same materials, and look exactly the same.

^^ Ha. Spoke to a very nice chap who had some sound advice. Still.

Who says? SRAM's claimed weights (which in my experience are usually pretty close to reality) for 10-speed RDs are 178g Force, 188g Rival and 200g Apex. All the specs, including the upgraded materials on the more expensive ones, are on the SRAM website.

They all function the same when new, and you have to go all the way to Red to get the ceramic pulley bearings, which is probably the one bearing on a bike where ceramic is really worthwhile.

Any suggestions for a good dual band router? My virgin hub thing seems incapable of coping with using both bands simultaneously and grinds to a halt.

I'm sure I've seen one mentioned on here a few times but can't find it now.

That's a private car park. I can't find any contact details for it on-line, but this suggests that there probably aren't any cycle parking spaces. I may be out of date here, but I think cycle parking has only been installed in some (underused) public car parks in the City.

I think you mean that all the city if London car parks have cycle parking. In all the examples I've seen there is bike parking opposite the security guard room so there is someone overlooking the bike almost all the time.

Sorry, missed the crucial word 'front' out of that. Force, Rival, and Apex are all listed as 88 or 89g, Red as 58g.

I just stuck a 32gb memory card in a dodgy card reader and it immediately corrupted.

It is a new and high quality card, I know it was just the shit reader that fucked it up. I put it back in my camera and it is not reading. Is there any quick solution to this other than getting data recovery software?

If you are looking at 10 speed the front mech is the same, only difference is finish and branding. The rear mechs are also very similar .. Differences (excluding wifi) are Apex has an aluminium outer cage and steel inner cage, Rival has aluminium outer and inner cage, Force has a carbon outer cage, aluminium inner cage and magnesium alloy inner body link.

The Red front and rear mech's of the same design have additional machining to the aluminium body pieces .. With the use of carbon for the rear mech cage, inner body link and ceramic pulley bearings .. and titanium for the front mech cage.

Buy a decent reader and try formatting it?

Or just try formatting it in a camera/other device?

Can someone suggest a cheap/free parking just outside congestion charge zone possibly south of river today?

theres a couple in Charlton for free troughton road has a free parking section and some that are free for 3 hours

question for you guys, how low of a teeth number can i go on a 130 BCD chainring?

Can someone suggest a cheap/free parking just outside congestion charge zone possibly south of river today?

You realise the congestion charge has been lifted till the 2nd of Jan (IIRC)?

yup! Just checked; cheers! So cheap parking in central then? Cheapest I found was NCP Crawford St £10.10 for 4 hours or £20.20 otherwise.

question for you guys, how low of a teeth number can i go on a 130 BCD chainring?

38.

Sheldon in OMG WRONG shocker!

104mm BCD 4-arm cranks can take 31t chainrings or 30T chainrings with an integrated M8x0.75 female thread.

edit: Respectful apologies for kicking him when he's [6 feet] down. I have no information on the availability of 31T and 30T "integrated chainrings prior to his departure from this mortal coil.

Not for the first time, but then everybody can make mistakes:

Squeezing in undersized rings does depend on how bulky the spider is and how deep the chain side plates are

e.g. 30T ring roller PCD is 121.5mm
inside diameter of chain with 9.5mm deep plates (typical singlespeed chain) 112mm
outside diameter over M8 bolt threads on a 104mm PCD = 112mm

so there's an overlap unless the bolt heads actually overlap the spider arm and the spider arm itself provides the necessary padding to let the chain clear the bolt heads. That would need 8mm holes in the spider arm and exactly zero material outside the holes

Does anyone have suggestions for alright road shoes on a rather limited budget*?

I've narrowed it down to these 3 so far, but would be interested to know if anyone had any other suggestions, or experience of these;

Gaerne G.Avia
Mavic Peloton
Bontrager DLX

I know I should go to a shop to try things on really, but there is nowhere local to me that has much.

*Around £55

but then everybody can make mistakes:

I know of one person who can't.

so is 38 right?

EDIT: its the sugino RD2 if that helps?

Another £20 gets you some Giro Trans which have been pretty good over the last three years.

I guess the key factors here would be

Clarity and specificity of the question
Accuracy and completeness of sources
Bias vs Respect for the truth
Declaration of the answer's limitations
and
Delusion vs Hubris
