  1. http://www.macnibbler.com/events/snowdoniaenduro2009/ Mostly XC but we (Matt Barlow, myself, Will Arnold and Craig Davies) did a trials demo for the enduro event. Nothing fancy just a few tables ands rigs and loads of grass! £10 to whover finds my brother in the XC

  4. I think you're right to. Stick it in and pedal backwards

    ive been waiting for this for a while I think that you seemed more relaxed on the mod, yet you can still pull the same sized moves on the stock craziness. And you seemed to be just at home on the simtra as the KOT which is pretty cool! And move wise you're looking pretty good, none of it seemed flukey or 'just about', nice one! Anyway nice to see you still riding. Get back to it Sam! ride more! When I get some time, Ill try sort out a ride near you
  8. 2 flat heads would be best, but ive only got 2 hands so I couldn't hold the 2 screwdrivers + turn the crank with my third. Nor do I have two flat head screwdrivers in my bag/car
  9. if it aint broke, dont fix it.
  10. yeah this is the pain bit. you need a flathead screwdriver, and just use the corner of it. Its not ideal but it works. Failing that, a bradawl (sp) works, or a kebab skewer etc. Just put the screwdriver blade into it, and then pedal backwards. Thats the easiest way I found with my ENO to keep it tight, gta experiment with bike/crank angles though. And make sure its in as deep as possible so it doesn't slip out and gouge some of the metal away
  11. ich muss arbeiten, leider nachstes woche aber, werde ich frei sein!

    Will A,

    i didn't think that made a difference? You can buy sealed bearings that do exactly the same job as caged surely? Hence why sealed bearings have a fillet radius on the contact edge to the bearing cup. Otherwise itd be a helluva lot cheaper to sack that off and just make sealed bearings fit for squared corner bores. meh, im not bearing expert though.
  13. is that craig pearce as in, canberra craig pearce? Has he still got that megamo?
  14. the lynx although Im not sure about the lite, the lynx (and the stock version the pirahna) are build pretty toughly with nice sized tubing for stays so they wont fold like cheese
  15. that was cool vid I was looking at those sections thinking how long it took me to get up stuff 2 years ago inthe comp, and alex just vroooom done. Looks really controlled though everything he did. Good effort!"!!! You make the vid rowan?? Props buddy tis a good un
  16. +1 Never watched you before bud, but thats really good! As everyone says, you've got a really nice style and a power that (no offence) doesn't look like someone of your size would have Really good riding, nice one!
  17. happy birthday stan!! See you in france or sooner, so be prepared
  18. riding spots = none. so good choice there, well done If you want to ride, come to swansea, where theres EVERYTHING. Same amount of fit girls (huge percentage, huge breasts etc), much more riding, and an awesome night life Cardiff night life is pretty damn mint tbf, you wont be bored there put it that way. The uni's really good too, its just riding spots that let it down

    Chris Akrigg

    lol Thats just so cool... Akrigg pulls another one out of the hat. Maybe hes reading this thread, whats he gna do next?
  20. how do you crack anything? theres no weight to you... also ddid you fit that cotton reel in your garden?... lol
  21. Say you have a master piston size of say (because I dont know) 15mm diameter. This pushes ONE piston of diameter 15mm similar to how a BB7 works. This gives a master/slave ratio of 1:1, obviously. Now if we say the 15mm master pushes TWO 15mm diameter pistons, this can be equivalent to a single piston of a larger size (NOT 30mm diameter btw) and thus gives a greater force applied to the pads/rotor 1.76714 * 10-4 : 1.76714 * 10-4 Is one master to one slave 1.76714 * 10-4 : 3.53428 * 10-4 is one master to two slaves. This is equivalent to a 15mm diameter master to ONE 21.21mm slave Now I think you've grasped this bit, its for those that hadn't. What you're saying is if you had one slave or two slaves, if the pads were the same size, why is there a difference in friction/force? Well first of all, don't confuse force with pressure: Pressure = Force / Area Force = Pressure * Area Hydraulic fluid exerts pressure onto a piston surface area, which creates a force. So the piston pressure is the SAME in the same sized 4 pot/6 pot brakes, but the fact that there are more pistons, this INCREASES the area and as you can see from the formula, INCREASES the force. So, although you're pulling on the lever with the same force, you creating the same pressure in the fluid, which creates the same pressure on the pistons, BUT because there are more pistons/larger piston area, you're creating a larger force! Hope that helps
