I'm sure the question has an answer - it's probably the subject of a PhD dissertation somewhere. On hills, according to the article I've posted below, there's a measurable effect of cadence on the economy (efficiency) of uphill cycling, and the cadence you can maintain without gears is going to be determined by your muscle and your muscle alone. However, as we know, geared drive trains are less efficient than SS ones.
On flat, with the right ratio, I reckon SS should win out.

i was thinking it wouldn't be a bad idea to get myself a replacement before the contact's over...
has anyone had to deal with phone replacement under these circumstances?I had my phone snatched out of my hand by a kid outside my flat last year - I was carrying some bags and couldn't run after him. I called the police when I got into the flat and two plain clothes officers were round in about three minutes, and took me on a tour of some of the dodgiest corners of the neighbourhood looking for him, with no luck.
I would have felt pretty grim if I hadn't REALLY had my phone stolen, put it that way. Anyway, I got a crime incident number and Orange sorted me out with a new phone through their insurance (which is less than a tenner a month, I think).

Dude, I know you're not the first, and you won't be the last, but when you say you've had a search around the forum, how deep and involved was that search, there are many threads on here about aerospokes, arrospoks, and you seem to have conveniently missed reading any of them. If you had read them, you'd know the feelings both good and bad that the arrospok engenders.
There are also plenty of threads about bike shops, good bad, indifferent as well as online stores that people use.
We'll help you, if you help us, do some of the leg work and ask a question which isn't open ended, and which we can answer if you've been on fixed gear gallery, or velospace, people who post up their bikes will tell you what parts are on them, it ain't that hard. From there you can find distributors, prices, pros and con's and make a decision about whether you want them enough.
Signing up, asking oft asked questions and then getting your nose put out of joint when you get sarcastic answers isn't the best way to start a relationship. If you have been searching this forum you'll have noticed that its not a place for the faint of heart or those with thin skins. We're all lovely people when you get to know us, but starting out with an inane question about a piece of kit that divides opinion isn't generally the best way to start out.
I could find the aforementioned threads for you, but where would be the fun in that.In the words of Ricky Roma in Glengarry Glen Ross: "You never open your mouth till you know what the shot is."

I'd go down the Bob Jackson route myself but have a Condor Pista for Sunday best. The Charge Tap route is a way of getting something more or less indestructible for everyday commuting. I'm going to tape over the decals to make it look like a piece of crap when I lock it outdoors as I have to at work (breaks me heart). Couldn't bring myself to do that to a Bob Jackson.

GSM Triangulation accuracy depends on the cell site density of the area the phone is in. In London, you might get down to a 50m radius if you're lucky, but in London that's a lot of places to search. In rural areas, you might be looking at a couple of miles radius. I know this because I spent two years looking after location-based services for Orange. GPS is the way to go.

Power drain has been a big issue for GPS units - until recently, the idea of having a GPS that went more than a day on a battery charge was a bit of a joke. However, I was at a conference in Malta a couple of weeks ago and saw a presentation from the CEO of a company that seems to have solved this problem:
I quote:
*A GPS receiver built using Air’s GPS receiver technology need never be switched off. Always-On™ technology means that the power consumption when tracking the location of the device is around 2 orders of magnitude LOWER than conventional GPS solutions.
This has two important benefits:
CONTINUOUS LOCATION: For the first time, mobile, battery operated devices can be continuously aware of their location. In addition to supporting established applications such as navigation, this will stimulate a new generation of proactive location based applications and services which don’t need to wait for an input from the user.
INSTANT LOCATION: When first enabled, conventional GPS receivers can take many minutes to calculate their location (depending on signal conditions). An Always-On™ GPS receiver is continuously aware of its location – hence the location information is always instantly available on demand.
The availability of Instant and Continuous location information in all kinds of mobile, battery operated devices including cellphones, cameras, watches, games consoles (and many more …) will find an unimaginable number of uses beyond just navigation.*They develop chipsets for OEMs - one big market for them is digital camera manufacturers, so that you can geotag every photo you take. They don't mention bikes here but it's an obvious extension.

I just bought myself a Catlike Whisper Plus helmet after years of never wearing anything: I've worn it a few times and it does have great airflow to keep your head cool. Doesn't look too bad either IMHO, though my girlfriend says it looks 'weird'.
@Julio: I've just put my Giro 'Bad Lieutenant' GI style 'boarding helmet on Ebay starting at a tenner. No bidders as of this morning so if you're still interested and there are still no bidders, PM me and I'll end the auction and let you have it for that price.
I reckon the adjustment nut on a Brooks would snag my nutsack.
