The rotor has to contact the whole of the pad. Otherwise, eventually the pads will close on the uncontacted part and the brakes will stop working.

Seeing as there a bit of interest in this, here’s a bit of education:

As a rule of thumb, the pressure you see as you drill down into the earth is governed by the density of salty water, that is around 0.45 psi/ft. So at 10,000 ft the pressure is 4500 psi or 300 atmospheres. This is called normally pressured. Rock strength is typically around 0.7 psi/ft, so to frac rock at 10,000 ft you need to apply a pressure of 7000 psi.

In some parts of the world you get what is called overpressure, this can be due to a number of reasons one of which is rock compaction. As layers of rock build up due to accumulation of sediments, the rocks below compact. This would normally expel water, but if the water is trapped it can lead to pressures in excess of normal. The Macondo well was drilled to over 18,000 ft, if normally pressured that would be 8000 psi, in fact reservoir pressure was over 12,000 psi. This was known about and was not the cause of the disaster, that was more due to a failure to properly cement the casing (pipe lining) in the well.

One of the drillers I used to work with told me a story of using the shear rams. When you lose part of the drilling assembly down the hole you have to go through a procedure calling fishing, basically using specialist tools on the end of the drillstring to grab the ‘fish’ and bring the assembly back to surface. They had been fishing for several days and had managed to grab the fish but it had fallen of again a number of times. Finally they got the fish to surface and the driller said close the shear rams so that if the fish dropped again it would only fall onto the rams and could easily be recovered. …… Unfortunately, the fish was 90ft long and the shear rams were only 30ft below the drill floor – you can see why the driller was not the most popular person on the rig after that.

I was expecting to be adding a negative review here, but fortunately I have a more positive experience to relate.

I pre-ordered a frame through the Black Friday Sale with a delivery date in early January. I was disappointed that they took full payment for a pre-order at that time. I phoned the Brighton shop this morning and they confirmed a delivery date slightly later in January but more importantly were happy to just take a 10% deposit. I received a refund of the other 90% straight away. This seems to me to be a reasonable approach. I suspect the issue is with their online ordering system and you get a better service through the shops.

I use these for abroad :-

The 1030 has a sd card reader so you can just use the one out of the 800.  I think the europe maps are also available to download for free from the Garmin website. Also openmtbmaps has more detailed maps.

Thanks CraigW that works, I thought I had tried that already but it must have been one of the other options.

Leffeboy, I do have a Garmin, I’m trying to use these old files with it.  But thanks for the Excel suggestions.

Ok, it appears to be Magellan Explorist XL format.  But that is not one of the options in GPSbabel.  I am trying to convert it into a gpx file.

Onzadog, liking the sound of your sealed <span style=”text-decoration: underline;”>rum</span>, ummm.

Seriously what spokes and nipples did you use when you don’t have a hole in the rim bed?

I would second Sidi’s.  I have two pairs.  They are more expensive than other makes but work out cheaper over the long term as they last so well.

Only the first £30,000 is tax free if you are lucky enough to be getting more than that. After £30,000 you pay at your marginal tax rate.

Hi Richard

To be honest I had never heard of the Deeside trail ITT but looked it up, looks an interesting route. There are some serious climbs on that especially if you are doing the extended route via White Bridge and Glen Lui. I don’t know all the route, but I would expect the extended section is also the most technical part.

Hi, I’m a local and just taken early retirement so have time on my hands. I would be happy to act as a guide if I’m around at the time. There are plenty of options. Send me a pm if you are interested.

I had a similar issue for a project at uni, where I was trying to calculate how long it would take for a droplet of molten wax to solidify when sprayed into a fluidised bed. As far as I could tell there was no analytical solution. I ended up using a numerical solution dividing the droplet into several layers and calculating the heat balance for each one at small time steps.

Have you looked at Ride Sierra Nevada. They ride on the Grenada side of the mountains compared to Ciclo and Switchbacks. I would say, if anything the trails are better than on the South side. Weather may be a little warmer as well.

The Lecht and Glen Shee have snow making on their nursery slopes. They are never going to be able to make enough snow to interest the serious skiers but beginners don’t need a whole lot.

We stayed in 11 Westgate B+B in Pickering last year. It’s run by mountain bikers so they can advise the best routes. Can recommend it.

Yes, that’s probably the best solution, thanks.

Yes, the glue that comes in the tubeless repair kits. I have had both super glue and more conventional stuff and both dry up after the tube has been opened the first time.

Don’t squirrels bury acorns and stuff for the winter? I don’t think they properly hibernate.

Nor sure I fully understand the question but you can use HLOOKUP to get the column nested with VLOOKUP to get the cell.

I got the XS for £2850

Did you buy the Dura Ace one that was on their site this morning?

No the Ultegra DI2. Had my eye on it for a while. Thought I had missed it yesterday when they announced their 2017 range, which I don’t think is any better really.

We bought some stuff from this place in Glasgow

They specialise in Ercol, G-Plan etc from the 70’s. Might be worth a call.

I’ve had one since May. It’s been all round Scotland and to the Alps. Best bike I’ve ever had and I can’t see me changing this in a while, which for me is saying something. I’m 5′ 7″ and ride a medium.

Not done them myself but a few ideas on here:

I used to live in Oman, one day I was cutting the dead fronds off a small palm tree in the garden and a Racer snake fell out of the tree right in front of me literally inches away. I don’t know who moved quickest…

If you replace your chain every few months like you’re supposed to you have a never ending supply of spare links. Never had a problem and I get 2 years+ out of a cassette.

When I opened this thread the picture of the Russian ship came up and then just to the right the advert for World of Warships started – it looked like the Russian ship steamed across the page was targetted by torpedoes and then was sunk. Felt a bit weird

I created a GPS route on http://www.mtbtrails.info that has all the data, although in the end I didn’t actually ride it.

Never been to Kilmun but Dawyck is worth a visit. Also handy for Glentress if you fancy a ride at the same time.

I’ve used this website for Spain, Italy and Romania. Seems to work quite well. It even had the bike trails I was riding in Romania 2 weeks ago.

My mother lives nearby in Belford but when I visit I normally stop off at Innerleithen. There are some trails listed here:-

Can’t vouch for them but some sound if they might be suitable.

Just a taster before I get time to write a longer review.

Bike is now below 27lbs after converting to tubeless. Did the Torridon lollipop on Saturday and Cairngorm – Cairn Lochan loop on Sunday. Still a fair bit of snow up on Cairngorm but not a breath of wind.

alialiali’s comments just don’t seem to get what a big 29er is for, they mostly seem to be “I wish this long travel 29er was an xc bike”. The wheels are pretty ideal, and most people replacing the tyres will be going for grippier not faster; the ibex is alright in the dry but you’ll soon find its limits on anything softer or slippier.

Yes, I found the Ibex’s slippy compared to my normal Magic Mary/Hans Dampf combo, but to be fair I was running them 5 psi higher than I normally would due to not being tubeless. Having said that, I bought this bike for big days out in the mountains, not wet days in the forests, so I might stick with the Ibex’s for a while.

So Jeffsy arrived yesterday and after a rapid bike build, took it out for a spin. It’s fairly light (27.4 lbs with pedals) and definitely fast. I don’t have the suspension setup quite right yet, it seemed a bit firm, but towards the end it eased up a bit or maybe it was that I let a little air out of the fork – more experimentation needed.

Size wise I’m 5′ 8″ and this is a medium, if the seattube had been shorter I probably would have gone for a large but the reverb is almost fully into the frame. Having said that when actually riding it I didn’t feel the toptube to be too short.

The saddle (SDG Circuit) is not very comfortable and that will be replaced, also I need to convert the wheels to tubeless and the 32t chainring is too big, it will be swapped for a smaller one. All-in-all looking forward to the weekend in Torridon.

I’ll report back, it should get a good shakedown at Torridon next weekend. My previous bike was a Trance X 29er which was surprisingly good. I demoed a Hightower, a Transition Smuggler, a Ibis Ripley LS and a Trek Fuel, I found them all good so in the end it came down to value, the clincher being the carbon wheels with the Jeffsy.

dare I ask, …

The frame is too small for a conventional water bottle so they have developed their own. However, they seem capable of designing, building and delivering a complex mechanical construction on time but not a plastic bottle :?:

I’ve run one in a 29er Pike, so it is wide enough. Not sure about clearance on the brace though.
