  1. will this super trials guard fit the middleburn rs8 24mm cranks ?
  2. i will be heading out 7am saturday morn. aim to arrive essex half 10 gives us 2 hours to settle in before the trial booking and practice.
  3. i am going to be driving from congleton with two spare spaces on my bike rack, to ligten the load of fuel costs we could split the fuel to about £20 each. here is my route http://maps.google.co.uk/maps?saddr=cw122au&daddr=CM1+3QR&hl=en&sll=52.719726,-1.014761&sspn=2.31915,4.916382&geocode=FXleKwMdMnje_yk7e5kBDUV6SDGLw-KWftfOzA%3BFQPmFAMdr2sFAClr3AnVQZXYRzEw9QSm9ZQB6g&oq=CM1+3QR&t=h&mra=pr&z=8
  4. whos going to the trial at barrow farm, essex on the 13th

  5. Depends on the quality of the final mould you want. The moulds I have made start by making either a foam or wood model of the part you need. Then take a mould from that. Rub that mould back flat. Then take a second mould from that, rub that back. You will have a perfect flat surface with no high/ low spots which you can make your final moulds from. Then make your final mould Which you use to produce your carbon parts from You can cut out the first two moulds. But all the carbon parts you make from that mould will need rubbing back to flat. Which takes time. If your only making one part that's ok. But even that way you are looking at One day to make the part, then another for the 1st mould and Another day to mould the carbon part. Followed by another day to flat the carbon resin and laquer it. Making moulded is easy its the flatting off resin that takes ages That's still 4 days work .
  6. If were designing carbon to those grades it would cost way more than that. You would be going into tens of thousands. I was thinking pay josh a weeks wage plus the cost of materials your well into a grand. Which it would take at least a weeks work to produce a mould and the final product.
  7. That bolt in carbon part would cost you the most, as it would require many hours making moulds for it. If it could be wraped rather than bolted in. I would take a guess it would come in around the same price as a jaf frame build around £350 Plus the price of a large jaf carbon repair however much that normaly costs. But that bolt in should cost around £1000 as a one off
  8. I use them now and like them. I found they feel bad if you don't run them forward in line with the stem angle
  9. If you use the hope 180 trial or trial zone rotor You need the j adaptor for 183mm
  10. Modify a silicon cake mould and mould the end out of carbon or fiberglass
  11. I would have viz rims but tarty are out of stock with no dates. Those forks are strong the old echo forks I had used to flex like mental. This bike is strong where it needs to be. But light in the places it can be without a risk of it breaking

  13. Voids in the carbon due to air pockets left in the layup in the manufacture. Those air pockets/voids are just as good asdrilling small holes in alloy bars. Does this help you understand how they are just snaping. Having said that a carbon bar bonded together correctly with no air trapped in the layup will be much stronger than alloy bars. But if they look like an aero bar inside there basicly scrap
  14. Trialtech sl bars get my vote they have a warranty. It may be 3 months but if your going to get a problem with carbon it will happen in the 1st month in most cases
  15. U got lucky. What were saying is alloy bars are much simpler to make and have less chance of mistakes. Where as in carbon manufacturing defect I would say is much more common place.
  16. I think some carbon bars snap as a quality control fail. If there are any voids/ air in the mould it will definilty fail at that point. And i can be 100% sure no trial bar manufacturer has a x ray facility to check the quality of there bars. They will just cut open the odd one here and there. On this I won't buy any carbon bar without a warranty. Unless they were to say they checked every bar for voids
  17. You can buy the remote for the silver as an add on. I think
  18. Yep I got loads of grip tape for extra grip works really well. Only problem is It gets worn and falls off the pedals after a week of so, but its cheap and works
