    Sometimes the gap is larger, but this is inconsistent and can be quite difficult to distinguish for the 5-band resistors. The blue ones are also harder to read, perhaps because the colour contrast is not great.

    If in doubt, I measure the resistance with a DMM.

    The tolerance band is suposed to be fatter. Mostly though, you can tell if reading the other way gives a weird value.

    1M is a common value. 140R is not.

    I’m 180cm and on a long with 150mm forks. Also have relatively short legs.
    I’m sure a longer would have been fine as it doesn’t feel especially long when sat down. I wanted something playful and find that it climbs well and feels great when stood up.
    Where are you? I expect there will be a Moxie somewhere nearish you that you can sling a leg over.

    I’ve got Cura 4’s, which I bought from Bikester.
    They are plenty powerful – enough to have the odd OTB moment while getting use to them.
    They are also fairly easy to bleed using a SRAM kit (use a new one so you don’t mix oil with DOT) and feel bomb proof.
    Brake pads are not ubiquitous, but seem to be getting easier to find in the UK in various brands.

    If cost is the issue, taking the train will cost more than the petrol used to drive in, even at today’s bonkers fuel prices. A return is £18.60, which is frankly mental, and I doubt it’ll use 9.5l of fuel to drive it.

    Some folk cycle to New Mills Newtown and get the train from there. Peak return ticket is £11.30. Better value if you do this as a regular commute as you can get a train card.

    I’m a procrastinating science person. Not sure about clever.
    If the balloon material has negligable mass, then it’s just the volume that matters.
    A sphere and a thin disc can have the same volumne, but very different surface area.
    Also, surface area and volume do not scale in the same way – see:
    https://www.bbc.co.uk/bitesize/guides/zwyfxfr/revision/2

    This is proabably not what you want to hear, but if all the shapes are similar, you can proabably get away with surface area as an estimate of the final volume once you work out you need 1 weight for surface area X-Y and 2 weights for Y-Z, etc.

    Edit – I type too slow, but think we’re all saying the same thing.

    It could be lower. I have relatively short legs, so it is probably not an issue for most folk.

    You can get a 2.3* on the big dog with plenty of space, but I don’t think many 2.6’s will fit. This and the standover height are the 2 gripes I have with it. The weight is only a problem when you have to lift it over something and it’s no worse than most of the other ‘hardcore’ hardtails.
    Not sure about the Scandal.

    *edit. And website says 2.35 max, although that may be a little conservative.

    The steel frame is 2.7 kg vs 2.0 for the aluminium.

    If the panel is made from planks of solid wood, you need to build in plenty of room for expansion and contraction across the width of these. Glueing them is going to cause problems. Accoya is also a bit tricky to glue well.

    Sorry for the slight hijack.

    The MRP fork has been awesome considering the mud its had to deal with. After 1 year 1500 miles it was clean as a whistle inside. Perhaps its the front mudguard, but I’ve never serviced a fork that clean inside. Not even ones that i’ve opened after 3 months to change something.

    Is that the Raven? In any case, good to know as I haven’t touched mine yet and was starting to think I should.

    Back on topic. My winter bike = summer bike with a different rear tyre.
    Or something on a turbo trainer.

    Thermal energy is a useful term here, even though different flavours of scientists and engineers use it differently.
    Thermal energy is often defined as the product of the Boltzmann constant and the absolute temperature (in Kelvin). This is related to the enthalpy of the system, which is a measure of heat and heat transfer. Heat transfer is what we feel, not temperature.
    That said, and as others have pointed out, humans have a relatively narrow range of temperatures in which they can survive and one’s experience of temperature in non-linear and depends on what you’re used to.
    In my experience, 20 oC is not/does not feel twice as hot as 10 oC.

    A friend of mine is keen on one but he’s not sure about an MRP fork. Any pics yet?

    I have an MRP Raven on my On-One Big Dog.
    Frame is pretty good, but could have more standover height and won’t take a particularly wide tyre.
    The forks are good. Once set up right I can’t fault them and would have no qualms taking them over a Pike.

    Alpkit are knocking out their 6l packs for £25 in the sale at the moment:

    I’ve used one of these for a few months. Quite happy with it. You can get 2 water bottles in it (one each side) and/or a bladder if that’s a priority.

    Right knee was good after a few days.
    Left knee took much longer – months.
    Depends on your age, how much damage has been done, what if anything else they do while in there, and probably to some extent how good the surgeon is.

    I have a grid trail butcher in the gripton compound. You can still buy these, but I guess they have been replaced by the T7 and T9 versions.
    https://www.specializedconceptstore.co.uk/product/16407/2020-butcher-grid-trail-2bliss-ready/

    One does wonder if some of this is just rebranding though?

    I’ve had plenty of quite horrible knee injuries, most of which were not bike related. My knees are somewhat on their last legs (probably a pun there somewhere), which is why the knee pads were on in the first place. However, I don’t usually wear them to the supermarket. Perhaps I should.

    samhay

    OK, thanks folks.
    I’ll take that as a ‘carry on as you were’. At least pads are a whole lot more comfortable than they used to be, and yes, almost certainly better outcome than had I not been wearing them.

    Don’t buy an airshot unless you need one.
    You’re also welcome to borrow mine if you’re on the Hayfield side of the Peaks.

    If the DHR on the front isn’t worn out (or similarly the one on the back), it should be fine on the back in winter. I use a Specialized Butcher on the front and they’re available.

    I used it quite a lot over the last year to record lectures.
    It records to the cloud, so if you don’t have a great internet connection, I can imagine it will be problematic. I have also used quicktime (on a mac), which works ok, but doesn’t allow you to do the talking head thing. For this, quite a few folk seem to use zoom, which may be worth a try.

    My problem with the bitscope is that it doesn’t look very robust, but I do have a habit of allowing scope drift (ahem) and buying something a lot more than I need

    The Bitscopes are more robust than they look. In part because they are very small. I have very expensive scopes to play with at work if I need to twiddle knobs.
    When I bought my bitscope, they had much better cross platform support (i.e. they don’t just run on windows) than the competition.
    They are not super accurate/quiet, but I use them to play with microcontrollers and the like where you may want to monitor digital signals along with analogue outputs. For a kid getting into this stuff, I would imagine they would be more than adequate.

    As an ex rugby player, the survey doesn’t work very well either. Especially one who is now a rugby parent. I gave up.
    Also happy to have a chat by DM. In short. I had a number of concussions while playing, which ultimately led me to play in headgear. Can’t remember if I used to train in it. I expect not.

    I have a Bitscope micro:

    As long as you don’t mind driving it with a computer, it’s pretty good for mixed signal stuff.

    Porridge is for special days. As are dogs.
    For the rest of the time Newtonian muesli is just fine. Instant coffee on the other hand is the worst kind of self abuse.

    OP – if you watch your wife make the porridge, you’ll collapse the wavefunction and find out what she does differently.
    I say this a someone who dabbles with quantum mechanics and eats muesli.

    It would be mildly interesting to see what unis are making of last year’s intake and what they make of the coming academic year’s intake, especially those studying sciences.

    I’m the admissions tutor of a science department in a RG university.
    Teaching was very different last year and difficult to compare to a ‘normal’ year. Anecdotally, I heard various comments about both home and overseas first year students with gaps in their knowledge. My first hand experience of teaching them backs some of this up.
    What has grade inflation done for our intake? We, like a good number of RG universities have more students than places. This poses problems, especially when you have to fit them into a teaching lab or clinical placement.

    I think @brant might have done this at one point.
    Bottom bracket would be a bit low for me – I primarily ride in the Peaks – but may well be fine at a trail centre.

    Tried to ride the shorter Eryri loop on Monday evening. There’s a big diversion in place, I assume for forestry work. What we could ride was quite overgrown with lots of brambles in places and the boggy bits were very wet. We didn’t try the other loop and we didn’t start from the car park, so your experience may differ.

    >I think, when you exorcize you not actually ‘burning’ fat of course, but in effect you turn body fat into heat via the work of your muscles.

    The misconception (and apologies if this isn’t what you mean) is that when you burn calories, food, fat, whatever, it disappears. It doesn’t, that would break a fairly central law in physics and chemistry of mass conservation. When you burn food, you do chemistry on it and convert it into other stuff. Some of it becomes new you and the rest is excreted – as faeces, urine, breath, sweat and other bodily fluids.

    If you are losing weight during exercise, then assuming you aren’t stopping for a toilet break, most of this is via water and CO2 loss in your breath and sweat.
    Apparently you will breath out 840g of C02 and 160g of water for every kg of fat burnt:

    ^something like that.
    I have no doubt that the new Adidas-ified 5-10s will fit some people’s feet better. Feet come in different shapes and sizes and I am not keen on trying to squash mine into something that doesn’t fit/isn’t wide enough in the toe box.
    I’ve tried all the new 5-10/adidas models on and for me the fit is much worse. I have a couple of nearly-new old-stype freerider elements (the other option for somewhat-waterproof) that I will wear until they die. At that point, I’m hoping someone else will have sufficiently sticky rubber that I can switch.

    As a climber, I’ve been wearing 5-10s since the mid 90s and I know a lot of folk who have abandoned the company post-adidas for the same reasons.

    For those of us who liked the way old 5-10s fit (I have fat feet and not much else fits), it has been a real shame to see Adidas change the last in the new 5-10s.
    I would have to size up so much on the trail cross model to get enough width that it would look like I’m wearing clown shoes.

    I’ve had a thermoplastic splint fitted during/directly after surgery.
    Depends on the nature of the injury and, I expect, which surgeon and/or hospital you find yourself paired with.
    In any case, don’t be afraid to be a little pushy, within reason. If they offer you X, see whether that really is the only option.

    samhay

    Condolences. Sounds like quite a gnarly injury.

    +1 to a removable splint/cast if at all possible.
    In the summer, especially it will get rather fecund in a cast. Being able to wash properly once the wound has sufficently healed makes life much easier. I expect you will be advised not to get it wet for a week of so though.

    The new bird steel HT is available. If you fill in the form on their website, I exect you’ll get an email with a link to where you can buy one. They do look rather good. I guess we won’t know yet how complient they are though as no one has had one to ride/review yet AFAIK.

    Right you are. They did seem to have a lack of cameras on the top section, which seems odd considering how difficult so may of the field seem to be finding it.

    I running a Specialized Ground Control 29 x 2.3 on the back at the moment.
    It’s a grid casing, which is holding up to the Peaks nicely and you can usually find them on offer somewhere.
    It has a very round profile, which may not suit if you rely on the side knobs for cornering.
