    So are clubs good or bad?

    Probably depends on the club.

    A “drunk” squirrel has caused hundreds of pounds of damage at a private members’ club.

    The secretary of Honeybourne Railway Club said he originally thought someone had broken into the premises, near Evesham in Worcestershire.

    The floor was covered in beer and glasses and bottles smashed, Sam Boulter said.

    Mr Boulter, 62, said he then saw a squirrel “staggering around” after coming out from behind a box of crisps.

    ‘Turned on the taps’

    He added: “There were bottles scattered around, money scattered around and he had obviously run across the bar’s pumps and managed to turn on the Caffrey’s tap.

    “He must have flung himself on the handle and drank some as he was staggering around all over the place and moving a bit slowly.

    “I’ve never seen a drunk squirrel before. He was sozzled and looked a bit worse for wear, shall we say.”

    Mr Boulter, who estimated he lost about £300 in the incident, eventually caught the squirrel in a waste paper bin and released it out of the window.

    Extra weight would actually help when going downhill, providing that the weight doesn’t hugely increase your frontal area (unlikely to make much difference unless you’re carrying dustbin lids or something).

    Assuming that you’re just coasting and not pedalling, then the forces driving you forwards will be a component of gravity i.e. the steeper the slope, the greater the force. NB. The force increases with increased mass, although in a vaccuum, the acceleration would stay the same as more force is required to accelerate more mass (F = M x A).

    The forces acting to slow you down will be mainly the air resistance against you (approximately proportional to your frontal area and the square of your speed) and the rolling resistance. Rolling resistance is proportional to your weight and speed, but is generally quite low compared to the air resistance, so we can forget about it at higher speeds.

    So, increased mass will produce a larger downhill force which will be balanced (at terminal velocity) by the air resistance at a higher speed – hence heavier riders will go downhill quicker unless they are bizarrely shaped.

     

     

    Does this affect how quickly fat and thin squirrels can run up and down trees, too?

    Most definitely.

    The larger-boned squirrel will quite often mistakenly climb onto a branch that isn’t quite strong enough, so they end up plummetting to the ground. The more svelte squirrel will choose to clamber down the tree trunk which will be slower.

    How do you figure? A heavy rider will have more frontal area than a light one, so will experience more air resistance. Other things being equal, they’ll be slower as a result.

    Nice of the judge to say

    Nice of the judge to say things like:

    This is an illustration of how road users really should contain their tempers as tragic accidents like this can happen.

    It’s not really an accident if you intentionally drive like an asshole.

    I’m wondering if the judge is related to the driver:

    He lives in a rural area where the nearest shop is four miles away so a driving ban will create a genuine hardship.

    If you can’t do the time, don’t do the crime – or in this case, if you NEED your car, then drive responsibly.

    The only place I’ve ever even heard of cables snapping is inside the shifter body. Certain shifters have been known for it in the past. That’s a problem whichever way the cable is routed around the frame. I can’t think of any reason a cable would snap inside a frame where there’s nothing for it to rub against or snag on.

    Yep, I’ve only ever had a gear cable break inside the shifter.

    I’d recommend changing inners every 2 years if you want them to be operating at their best. I wouldn’t bother changing the outers unless there was a specific reason for it (e.g. poor performance or you want to change their colour).

    I thought that a lot of bikes

    I thought that a lot of bikes are stolen just for the components to be stripped and sold. How will marking the frame help with that? Seems like a lot of money and effort for very little benefit.

    Can we address the real issue – those pesky pedestrians, they are really whisper quiet. They are a real danger to cyclists – coming from nowhere suddenly stepping into the road. I find it hard to believe that there is no law yet introducing mandatory noise devices for them – I am thinking a tuba for each one with mandatory playing of such as soon as another road participant approaches. I think I’ll set up a petition!

    As not everyone is proficient with a tuba, maybe just employ some people to follow pedestrians around:

    The greatest threat for cyclists is imo vehicle’s emissions and not the vehicle itself. Full electric cars will just terminate thia problem. On the other hand, hearing is really useful to cyclists, I would feel really unsafe to ride with earphones. So yes a mild sound would be necessary, but even without it, battery only cars can greatly reduce the biggest threat we face daily

    Coincidentally, I just happened upon this article from 2017 that explores the possible link between Alzheimer’s and dirty air: https://www.sciencemag.org/news/2017/01/brain-pollution-evidence-builds-dirty-air-causes-alzheimer-s-dementia

    I’d much rather have cleaner air and electric vehicles as the noise issue is easy to mitigate.

    It’s definitely something to

    It’s definitely something to be aware of so there’s less of a surprise when suddenly being overtaken when you weren’t aware that there was anyone behind you (also applies to other cyclists overtaking you).

    In some ways, it highlights the issues that deaf cyclists face and the ultimate answer is to check behind more frequently (I’m a fan of using a tiny mirror for a brief look to see what’s approaching).

    What pressures do you ride them on for your weight? Do you knock any air out in bad weather?

    Haven’t tried the Sectors, but I had a very similar issue with Schwalbe Ones in the wet (reducing the tyre pressure below 70psi helped a bit).

    I’ve ridden with someone who was skittering everywhere on Ones. The tyre pressure being too high was probably the reason, but I wasn’t impressed. 

    I was trying to run the 25mm Schwalbes at around 80psi (I’m approx 90-95kgs) and they would just skid on any surface moisture. At around 65psi they behaved a bit better, but I changed them as soon as I wore them out which doesn’t take very long with the Pro Ones.

    I’ve currently got a 28mm IRC on the front that is lasting a long time and a 28mm Maxxis Padrone on the rear and have them both at around 70-80 psi. So far, the Padrone seems to be excellent – good grip and feels fast. The IRC has excellent grip, but I suspect that it’s not as pliable as other tyres and hence not quite as quick.

    I don’t think I’ll bother with the Schwalbes again.

    Haven’t tried the Sectors, but I had a very similar issue with Schwalbe Ones in the wet (reducing the tyre pressure below 70psi helped a bit).

    I ended up getting some IRC Formula Pros from Cycleclinic (https://thecycleclinic.co.uk/products/2017-irc-formula-pro-fusion-x-guard-tubeless-tyres) which were very confidence inspiring and seemed to be hard wearing as well.

    I’ve since started using Maxxis Padrones (http://www.wiggle.co.uk/maxxis-padrone-tubeless-ready-folding-tyre/) which feel a lot more supple than the IRCs and haven’t given me any trouble with lack of grip in the wet.

    Thanks for resurrecting this

    Thanks for resurrecting this thread – I can’t believe I hadn’t commented on it before now.

    I usually just say to myself “who’s eating this avocado?”
