2. Carbon Frame Seat Tube Crack Kit

1. Suggestions for carbon fiber frames and seatposts by Witold Walkowski, with interpolated comments by John Allen. I bought recently a used Kuota Kalibur carbon frame with carbon post. The post got stuck in the frame while being shipped by Fedex. Both the post and seat tube are not round but with a drop shape profile so you cannot even turn it.
2. “Repairing a carbon composite frame is definitely possible but it’s a complicated process — one best performed by people with experience, knowledge and the correct tools.
3. There is a crack in the center of the carbon, about 2cm long where the seat tube made the layup in the back bow out. Additionally, there's a crack on the right side (closest to the camera) about 4cm where the paint and the outermost layer of carbon lifted up.
4. If you can't feel it with a fingernail, the crack probably isn't in the carbon. Another trick is to whack the tube with a quarter over and around the crack. Do the same at a similar location that doesn't have a crack. If there are any differences in sound, the frame has probably sustained damage.

Me and my dad are arguing because I want to do it because my seat tube is mega big and I wanna cut it, and he is saying it will wreck it big time. Help me out please? Thanx Posted: Dec 8, 2009 at 23:51 Quote I don't think it will wreak your frame. I cut down my stg i-beam about 1 1/2 inches last year and it's still running strong. I'm not 100% sure if cutting it down will wreak your frame but from what I know you should be fine. Just make sure you file around where you cut internally and externally. Also keep the cut straight and clean because thats when problems will start happening. cheers. Imagine the horse as your bike LOL. >>> Posted: Dec 8, 2009 at 23:54 Quote joram-adams wrote: I don't think it will wreak your frame.

Posted: Dec 9, 2009 at 0:30 Quote Do you mean the seat-post or the down-tube (where the seat-post slides into)? EDIT: Just realised and it depends on what your frame is made out of. If it's thin metal, then yes, it could because it wouldn't have the extra support strength. Posted: Dec 9, 2009 at 0:32 Quote OOOOOHHHHHHH, The seat tube! Yes, cutting the seat tube will defiantly damage your frame. Please what ever you do, DO NOT CUT IT! Posted: Dec 9, 2009 at 9:10 Quote I cut the seat tube on my 08 cowan an inch. I rode it like usual and had no problems with it. I believe unless youre running your seat post with only two inches or less in the frame you will damage it. other than that I dont believe it will do any harm. My opinion is if you do it right youll be fine, but do it wrong and your seat tube might start to crack and could lead to failure around the seat tube/seat stay area. Its your frame, experiment away.

Just take it slow and do a good job. Posted: Dec 9, 2009 at 10:30 Quote woody-dh wrote: Do you mean the seat-post or the down-tube (where the seat-post slides into)?

The down tube is the tube that runs from the headtube to the bottom bracket shell. You put your seat post into the seat tube.

Posted: Dec 9, 2009 at 19:28 Quote what do you mean cut the seat tube? isnt that the hole where the seat post goes in? so are you trying to increase standover height?

That is exactly what he is trying to accomplish. Pay attention to where the seat post clamp is in these two pictures. Same frame.

Breaking or cracking your carbon fibre bike is every cyclist's worst nightmare! Ollie took a visit to Carbon Bike Repair to find out if carbon is repairable.

Biskey sw tanaka t22 jurassic 2017 2018. Carbon fiber is the raw material with the greatest potential for lightweight construction on the market and thus only as much material is processed as is necessary for the specific application and does not include the steering deflection on the top tube and does also not include a similar impact of a different kind.

Kickstart fl studio crack. Carbon is a material that depends on the axial direction of the fibers (anisotropic), which is decisive for the performance. In comparison, metallic materials have the same properties in all directions (isotropic). A broken, destroyed carbon fiber is much more crucial than a quirk on a metallic bicycle frame.

The material properties of carbon, fiber composites in general, are defined at the micro level in the manufacturing process, the main factors are fiber orientation, fiber specification and the choice of matrix. From this it is easy to deduce that even a smaller fracture leads to a considerable damage to the overall construction. Compared to metallic materials, which consistently have the same material properties in all directions. Aviation standard practices manual.
