What to carry when out.

The tyre patches I was referring to are self adhesive and go on the inside of the tyre link below:

They hold the tyre together if it splits, gave one to a guy doing the Mary Townley Challenge last year when he was halfway round (Inner tube was like a balloon through the side of his tyre) and it got him the 20 odd miles to the finish.

Some mobile phones allow you to make emergency calls on other networks if you can't get reception on your own network, mine does this though it seems to spend more time saying emergency calls only rather than T-M****e. Only works if there is reception with one of the networks.

If they fail or start leaking no amount of pumping is going to make them work properly again so why bother?

That's what I always thought, hence the question.

from what i can make of that "blocked" appears to be the signal to the satlelite is physically blocked by the depth in the underground. My belief was that your phone would conect to any network to connect an emergency call. In relation to tracking you using your phone i know for a fact this can be done how accurate it is i am not sure of but i do know this is done by the emergency services and other agencies. i am not sure of the tech side of this ie if you must have a signal etc . . . . .

Yep you need a signal and mobile phones work via base stations and cells, not satellites. I think the way the system works is your phone is constant communication with your nearest base station, effectively sending out a signal every few seconds saying I'm switched on and in the cell controlled by the base station (this is how they can track you). If you've no signal you're out of communication and can't make calls and can't be tracked, your phone might as well be off.

Most mobiles can "roam" for other networks - mine can.
Means a pricey call but worth doing.

Saying you can make calls without reception is a bit like saying you can use a food blender when it's not plugged in, or use a radio down a very deep mine

Couldn't you just go single speed though if the worst happened?

On a hardtail yes. Can't do it on a squidger cos the chain needs to change length as the swingarm moves.

sorry to show my dumbness what exactly is a rear mech hanger? I am getting a hardtail.

IIRC tracking a mobile via conventional means works by triangulation. Your phone should be in contact with several masts at once, it just transmits via the strongest signal. By marking a triangular area bounded by the three masts nearest to you, you should (in theory at least) be somewhere in that triangle.

Also, I don't know how much truth there is in this, but I've heard that active mobile phones transmit a tracking signal even when they are switched off which CAN be located by satellite. But it's very expensive to do and only really of any use to the security forces if you are a terrorist suspect or billionaire Russian businessman.

Now, who's that man in a black suit coming up my garden path....

It's the metal hook that the rear mech hangs on to.

Good point!

you're right, to get an accurate fix they would have to triangulate from at least 3 base stations at once but they can know which cell you're in from the base station your phone is currently communicating through. Not sure about the satellite tracking bit, sounds a bit far fetched (I don't usually go for the conspiracy theories) can't see the phone manufacturers adding in anything they aren't getting paid for (or maybe they are :shock: ). I'm now off to remove the battery and put my phone in a lead box, hmm not so mobile now.

Couldn't you go single speed on an FS if you locked out the rear shock?

I think I read somewhere that you 'could' limp home very gingerly if you had a total lock out for your rear shocker and left a little slack in the chain?

so people go on about what to take n stuff yeh, water,food etc, bike pump, spare tools n that, no one said anything about taking ur bike... i walked up a massive hill n realised i forgot my bike once

Regarding the mobile phone location thing.
"Triangulation" usually refers to two radio receivers finding the direction of an incoming signal, plotting those two lines on a map and knowing that the transmitter is at the point where the two lines cross.
As far as I know, mobile phone masts have no means of finding the direction a signal is coming from, all they can do is measure signal strength. A phone will be within a certain radius circle centred on any mast that can detect it, or within the overlapping area of two or more circles.
The more circles, the more accuracy, but it will rarely be as accurate as proper triangulation.

Take a hat. For warmth provided per gram carried, no other item of clothing can match it.

Not everyone lacks the same amount of common sense that you obviously do.

Pump doubles as weapon for when walkers get the hump as they didn't hear you coming or some chav scum tries to nick your bike, trust me you need to think about these things.

Tend to think if i bend a mech hanger i'll bend it back into place with an adjustable shifter, i alwats carry it with me. Might start carrying a spare tho.

re tyre patches

just returned to mountain-biking after twelve years - bought a trek fuel ex (a bit different from my old steel, rigid stumpy) and went out on my first ride. Half an hour in, I'm descending quickish and manage to steer into a rut running down the hill. End up with a small hole in front tyre, large hole in back tyre. Tyre patches would have been handy...

It is flinty round where I ride but the side-walls of the bontrager tubeless ready tyres seem pretty light. Was I unlucky or are they a bit light for flinty conditions?

ride_whenever

I usually carry the same, but with some extra bolts and chainring bolts and spare mech hanger. I'f i'm going with my gf then i'll take a spare cable inner. And I usually have a space blanket in case of exposure...

clas

a new mech hanger is vital.
hooning down coed-y-brenin last year and bang! hangers is snapped in half. no going back no repair and no chances. the upside was it was the last descent of the last day of the best weeks riding I had had for years and it happened near the bottom. I now carry a new mech hanger and about a foot of chain. as well as casualty blanket, phone, first aid kit, inner tube, some scran, tools appropriate clothing and usually everyone elses gear that they claim they cant carry because their hydration packs wont hold it all (and a pump of course).
and yes sounds like your tyres are a bit on the fragile side for your riding style as well as being tubeless and therefore not repairable from that sort of damage on the trailside.
