I would say nope on that one! (Assuming the glider is tethered to keep it stationary on the treadmill) to entrain enough air to create an oncoming wind on the glider's wings the treadmill would have to start a long way out in front of the glider. Due to the boundary layer forming that distance required to entrain the flow would mean that the glider itself would sit inside that significant boundary layer and so it's wings would never actually see wind at the take off speed.

Why does Spotify have video adverts? Like who sit's and watches Spotify? 'Watch this short video for 30 minutes ad free'... 'YOU'RE A MODERN RADIO!'.

Are you surprised though? Dumb f**ks (some with guns) following a dumb f**k in power. What the french would call inevitable.

Is that not a 'Frenchie'?

I spy a Bongo!

I would say no. I think at the top level then doing training off the bike to develop fast twitch muscles etc. becomes a thing but actually when you're starting out it's far more about practise on the bike to dial the movements but more importantly the timing to improve your technique. In terms of bunnyhops some of it will come down to the sort of riding you do. In the woods, on proper off road trialsy stuff you'll rarely find a time when the bunnyhop will be the best option (unless your surname is Akrigg) and with the confidence you get from using the cranks and having control over what the front end's doing I would start with pedal ups and on the side practise bunnyhops as a separate move but not necessarily onto something. I would practise bunnyhopping a (movable) bar to get the technique to get over something and then moved on to using it to get up stuff that I could already pedal up.

With confidence and commitment (along with a long enough run up) you can get higher with a bunnyhop than by using the cranks. If you use the pedal stroke you're limited by the entry speed while still being able to accelerate the wheel sufficiently to get the power into the move.

I read a good post somewhere this morning that explained how the vaccine was designed and works which was quite interesting. They explained that the vaccine just contains some of the protein that exists on the cell walls of the virus and works by effectively training your own immune system to recognse and attack that protein so that if you come into contact with the virus in the future your immune system is already primed to tell it to f**k right off. If that's the case I'm certainly less bothered by the potential long term effects of it. Is that Jane's understanding of it @Ali C?

I've yet to ride one but this is definitely something that I have no idea how they react to. Guessing the first few times the bike just tries to whip out from under you because you're not used to the power delivery?

Unfortunately the knock on of that is that it gives a voice to the old school anti-vaxxers who won't innoculate their kids against polio because it'll give them AIDS or whatever.

You don't know what you're saying... how can you not have trust in BoJo? Oh, yeah, that's right...

https://www.covid19treatmentguidelines.nih.gov/antiviral-therapy/ivermectin/ Like the rest of the advice out there: It works but it doesn't work.

It seems there are various possible everyday/existing drugs that are considered potentially useful against COVID including antimalarial drugs (amodiaquine) and antiviral drugs remdesivir and favipiravir.

I'm quickly getting into the 'don't give a shit' category when it comes to the rules that change daily. Don't get me wrong, I'm wearing a mask wherever I need to, being careful and sensible but basically Boris and his wanky rules can do one. So three households can't mix over the original 5 days but they can mix on Christmas day? And that's different and changes the transmission liklihood how? These are the f**kwits who not only got us into this Brexit mess but after four years are still fannying around wiht no sign of any kind of deal being in place. These are the c units who have handed out hundreds of millions of pounds in contracts to ferry companies with no ferries, PPE companies set up after the pandemic hit with zero history in providing medical suppllies and are then surprised when the PPE that has been provided isn't up to spec. They literally couldn't organise a piss up in a brewery and I have absolutely no time or patience for the c**ts. I don't know how the numbers are being reported in the states but I still don't like the way the numbers are reported in the UK- this deaths recorded within 28 days of a positive COVID test doesn't cut it. It makes it impossible to tell if John died in a car acident within four weeks of having a positive test when he was entirely asymptomatic and equally misses Jane who has been in hospital on a ventilator for six weeks before succumbing to the virus...

Sometimes I can be really frickin' dumb... Bought some 170 cranks for the MTB to replace my 175s to improve clearance. Yay. Think 'I'll sell the old ones to make a bit of money back' so put them in the ultasonic cleaner to give them a good scrub. Take them out and half of the anodising has either gone or mottled. Poop. 'Never mind', I think, I'll stick them in caustic soda for a bit and take the rest off and sell them as unique, polished examples... Done that this evening and I may have gone a little far as now so much material has gone that the direct mount threads have broken through the body of the crank arm, the spline fit is sloppy as hell and a pedal just drops straight into the end!! So it turns out Caustic Soda is a little more potent than I had assumed!!

Could his voice be any more annoying? Actually scratch that it could be narrated by Henry Cole.

There are limits to how well it'll work and at what point the flow will 'choke'. The diffuser itself doesn't generate the downforce, that's done by the low pressure (caused by fast flowing air) acting on the lower surface of the car. The diffuser works by returning that low pressure air back to ambient as efficiently as possible. Reducing the rideheight will work to a point and then it'll just suddenly stop working which, since the car will be naturally moving up and down to a degree (on it's marshmallow like suspension!), you don't want that happening unexpectedly. That's partly why you see F1 cars running quite extreme rake angles (Red Bull being the one that springs to mind)- they make the 'throat' of the system at the front of the underbody and the rest of the floor acts partly as a diffuser which can be tuned for what happens at high speed when your downforce winds on without risking a sudden, catastrophic loss of downforce. Sliding skirts do make a big difference and are used to seal in that low pressure flow that you want beneath the car. They're usually illegal in most classes since rules tend to have a minimum ride height. My gut feeling would be that for a floor that's working fairly well adding skirts would increase the downforce being generated by 40% or so.

Yes?

Yeah definitely worth an ask!

I ride a Whyte T130 that has a bit of a low BB and I quite regularly hit pedals. It's currently on 175s but I've just made the decision and am going to swap to 170s to try and ease that issue. I'd say if you're going to do it maybe go for it immediately as you'll be able to sell on the 175s easier and for more dolla brand new than if you sell them even lightly used. See if you can pick up a set of nearly new 170s on eBay or similar maybe to make it less expensive overall?

Urgh. Any idea what's under all that mess? Is it a star nut or something else? If it were me I'd just try bashing it further down the steerer to give you room to fit a new star nut...

I really hope George's performance has made the Merc bosses take note and maybe he can unseat Bottas in the future. To jump straight in and completely stomp all over Valtteri speaks volumes.

Does that also go for people on uplifts (either UK style van to the trailhead then injoy the downs or like the Alps where you can get a cable car up a mountain and then do what you like)? I haven't ridden a proper e-bike yet but I know my time will come, most likely when I can't keep up with my kids anymore (which hopefully will coincide with the batteries becoming smaller and the bikes smaller and lighter so less of a hinderance). I used to think of them as cheating but as they're becoming mainstream and now that the bikes are becoming more refined 'proper bikes', but with a motor, I have no issues with them anymore and to be honest if I could afford one now I probably would have one and use it all the time for normal MTB.

Hehe, yeah all that diffuser body work was done at Southampton and we still have and use that model! I'm also hoping to hook up with Xin and Willem on a bit of consultancy work soon too :).

I know what you mean. I watched the Akrigg 'behind the scenes' vid yesterday and it says a lot that the 'crux' of his part was the fairly nothing pedal gap across the stream. HIs part just seemed like the stuff he does day in, day out without any real bangers.
