  1. A random question for a rainy Sunday afternoon, for those of a technical mindset... 

    Were there any changes throughout the years, in terms of Magura Master / Slave cylinders, specifically around sizes / bores / strokes? 

    Some context to my question... 

    I have an RB Designs lever from the early 2000s. This is mated to a pair of later slave cylinders, I'd guess at around 2012 (newer Magura logo). It's been bled in a sink; definitely no air in the system, and yet when I pull the lever the slaves barely move. Everything feels rock solid, no sponginess or anything. Could it be that the bore / stroke on the RB Designs cylinder is not enough to push enough fluid to these later slaves?

    Obviously, it being an RB Designs lever, I'm definitely not ruling out it being a bit Leaky McLeakface, but I'd expected it to work even just for one lever pull... Or is my rose tinted spectacles view of "trials of the days of yore" clouding my memories and these levers always performed like ass? 

    Answers on a postcard...

    The entire south east of England is a joke. Unless you buy after a recession like we did or have lots of help from mummy and daddy, I don’t understand how normal people are supposed to be able to get on the property ladder.

    South West isn't much better. I was lucky when I sold my 1 bed flat for £140k (bought for £90k). It meant I could stretch my mortgage that little bit more and got my new place for £200k; but it's still an ex-council, 3 bed mid-terrace in not the greatest area... Next door just sold theirs for £250k so I should do ok on this one.

    Is this not the same as the Adamant 24 like I have just with a disc mount? 

    Seeing how I'm struggling to get a pair of rim brake compatible 24" rims I wish I'd found one myself! 

    I would think they're very similar if not the same. The rear disc mount definitely sold it to me, just need to swap the hub over for a disc hub so I don't have to run the magura. I bled it twice yesterday and I still cannot get the damn thing to work.  

    I have no idea on the geometry, I struggled to find anything that was for this year of frame (think I narrowed it down to about 2011 ish?). I'll get the tape measure out at some point and see what it is. 

    From looking at the pics, I'd say your Adamant is maybe a touch longer?

    Haha thats quite an optical illusion! Looks like a disc mount but pretty sure it's the spider / rivets on the rotor...

    I like these frames more than I should, looks fun and good to see you on a bike again dude!

    It's nuts isn't it!! I spent so long looking at the picture going "You twat, you've put the forks on backwards...." then I looked at the bike and realised I hadn't. As you say it's a really weird optical illusion!!

  5. The "prom-night dumpster baby" project build is underway. I know it looks like a s**t heap right now; it'll get blasted and painted at some point when the weather improves.

    Update - Now got the brakes on and set up, along with a different seat and some replacement bolts around the place as some were gash and rusty (although fitted with the current theme). Oh and I changed the front rotor so people don't think I bought the bike from Argos

    Good service, knowledgeable crew, actually get your product: pick Tarty Bikes ;)

    That one has to be somewhere near the top of the "Positives" list when choosing who to buy from... 

    Learn from my mistakes... do as I say, not as I did ;)

    Planes are powered by either a jet or a propeller so if that engine is working and going at take off speed then there must be some kind of air flow going towards the plane. How fast the wheels are going doesn't matter planes don't even need wheels. As long as there's enough airflow going over the wings it will take off.

    Exactly. The issue people have is they try to quantify it via something like a car or a person on a treadmill. The difference (among many) is that those are driven by the wheels / legs that are directly on the surface of treadmill. If the speed of the wheels / legs match the speed of the treadmill, it will stay in one place. 

    An aircraft isn't driven forwards by it's wheels; they're like casters, they just stop it scraping it's belly along the ground. An aircraft is moved forwards via thrust; moving air from infront of the plane to behind the plane at speed. The air, unlike a cars wheels or persons legs, is not affected by the movement of the treadmill. The aircraft will continue to move forwards through thrust, with the non-driven wheels just spinning at twice the speed. Eventually the airspeed will be great enough to create enough lift and ergo it takes off. 

    Think of it as running on a treadmill then suddenly someone shoves you from behind; you'll overcome the speed of the treadmill and fall forwards. Your driver (in this case your legs) is directly on the surface of the treadmill but the shove is not (its your thrust), which is why you fall forwards.

    I don't get how people don't understand that a plane would take off if it was going at take off speed on a treadmill...

    Oh my god the amount of arguments I've had over this!! 

    One person absolutely would not back down, even after explaining that I was an Air Accident Investigator... 

    There are too many things I just don't get, most of which would make me look like the biggest weirdo ever so I probably shouldn't share...

  9. My only real issue with the vaccine right now is the long term affects.

    While I'm no vaccine developing expert, I'd have assumed (perhaps wrongly I admit) that these things are tested over long(er) periods to ascertain any adverse affects down the line, especially when as you say this is something completely new and never tried before. As I say I could be completely wrong on this and it has all followed the exact same route as any other, but I think a lot of the publics reticence is this all feels very "political"... 

      PS I think you're better with the language than you think you are :)

    I liked the vertical posts but even taping out the other sections so the audience knows where they’re going would help

     

     

    Yeah, that section was certainly the best of the bunch with the most "flow" to the route they took and seemed more about precision that just big power moves. The other sections though, I had no idea where they were going next! We need more sections like what was used in 'Under Pressure'! 

  11. A-Mazing!! Cheers!

    Is it just me or are the sections really weirdly laid out? There doesn't seem to be any flow or structure like in mototrials etc. The guys seem to ride over one single obstacle, ride around the section a bit on the flat then ride over another single obstacle. Just seems to lack something. 

  12. Years back, I would have said it probably was too underground, but I don't think that is as much the case now. It seems to be more popular and respected than it ever has been before, and is more identifyable by more people than ever. Shame that the UCI still see trials as the ugly duckling of their genres and still cast it off to the side.

  13. I could only tolerate a few minutes and had to turn it off. About a quarter of a screen of actual video and the rest was giant adverts!! Shame as the 2017 coverage on youtube was excellent, although they never did upload footage from the finals in China which I was most annoyed with.
