  1. The frame I weighed using a kitchen scale
  2. The frame weighed in at 1900g I weighed it using a fish scale. The whole bike came in at 9kg, considering that the wheelset is 3.3kg and the tyres are about 450g each, that's not so bad
  3. Also got that on ebay..
  4. Got them on ebay
  5. Thanks guys It rides quite well, a little flex but not too bad. I think my old steel singlespeed is more flexible.
  6. I used a piece of long steel bar which I sharpened with a file..
  7. Complete bike..
  8. You can see the difference between the sanded and unsanded finish.. Next step was to paint a protective coating over the frame.. The finished frame is shown in the pic below..
  9. Sorry for keeping you guys waiting for so long but here are some more pics.. I repeated the process on the rest of the joints and it came out pretty well.. The seatclamp is also shown in better detail..
  10. Have to go race now, will post more stuff after..
  11. I then sanded all the joints, I sanded the ends of each pole prior to gluing to make this part easier. For the rear stays I added a wedge to fill in the gap as the radius there was too tight to wrap in carbon neatly(you could give it a bash). I dont have any pictures of the carbon being layered on because it was very messy and I didn't want to get my camera dirty. When applying the carbon, just ensure that there are fibres in all directions.. Once you are satisfied with the amount of carbon, the joint must then be wrapped in insulation tape with the sticky side up, I perforeted the tape once it was on, this allows extra resin to seep out.. The particular resin I used was ampreg 21 and can cure at ambient temperatures.. The last picture is the finished joint..
  12. After all the pieces were mitred, I fitted the tubes together and made sure everything lined up. I then used a normal quick setting epoxy to glue the pieces together..
  13. A lugged BB might have been stiffer but unfortunately the frame I bought didn't allow for that so I just used some more carbon in that area..
  14. A jig was then built (there are many ways in which to do this) and a parent frame chosen for the build. I copied the geometry of the frame in the picture.. I cut the frame up and took the necessary pieces i needed for the bamboo frame.. These all need to be ground in order for the epoxy to adhere properly.. The bamboo then needs to be cut and shaped to fit into the jig and onto the various pieces.. I will post more stuff tomorrow
  15. Bamboo poles were cut from a forrest. The poles were then cut to the rough length needed for the various sections. The poles were then washed and the nodes punctured to avoid the tubes exploding during heat treatment. The poles were then heat treated, this is done three times first to remove the waxy layer then second to remove the chlorophyl layer and a lot of the moisture, i let them stand for about a week before i did the third treatment, this is to remove more moisture and give the poles a nice colour..
  16. I'll start a thread with the details of the build soon, hopefully that answers most questions.. As for the poles, I'm not sure.. fun to cut and treat your own as you know they have been done properly..
  17. Thanks guys I have been for a ride today, it seems stiffer than my old steel frame singlespeed, still a bit of flex but not too bad. I think the carbon is better than hemp twine, I do know there are hemp fibers around but not the easiest to get hold of.. If you have spare time it is a really cool project to undertake. The hard part is drying the bamboo but if you can get hold of some online then it would be a breeze. I just treated my own to save on costs.. Cheers
  18. Here is a pic of the BB before I wrapped it in carbon...
  19. Hey guys, I used carbon fiber and epoxy resin to do the joints. The bottom bracket shell, the rear dropouts and the head tube bearing housing are steel. I mitred all the bamboo tubes to fit together and then wrapped all the joints in the carbon fibre..
  20. I have been working on this project the whole year, built the frame myself and even cut the bamboo for it. Today I finally finished the bike..
  21. Been working on this project for a while now and today I finally finished. I built the frame from scratch, even cut the bamboo down myself. So happy to be done...
  22. Yip that one...
  23. David George...Hey I just saw his nice bike
  24. I met a guy who brings in the parts briefly at a race, I was hoping he would see this ad. I am only 65 kg so I'm not too phased about the strength of the stuff, I'm confident with German engineers and I'm only interested in the rims which are actually(for the weight) super competitive in terms of price, they are super light and cost the same as about zipp or any other expensive brand.
  25. I am looking for someone who brings AX Lightness parts into the country. I saw David G had a full range of AX Lightness components on his new bike and I am interested in purchasing a set of their rims. If anyone knows who brings the parts in, or if he/she sees this article please send me a PM. Thank you
