Chris Davies: DIY Carbon Fiber Frame Repair - Part 2 of 2
Remi Russo: Nice but i guess he'd better get a new frame anyway .
Taweechai Maklay: Good Job
MadbikerNath: Nice job on that frame, bet your friend did wish he saved his money.
Jonathan Quiroga-Tinoco: Amazing job mate!!! congrats and thanks for the video
NAVISPEED1: great job!!
Sergio Jimenez: really nice job and nice viedo.
Garrett Kolasser: thanks for the video. i'm an ex body man but never did any carbon fiber
repairs. you answered my questions and made me confident in purchasing a
carbon fiber bike.
D. Lorenz: Nicely done.
Jonathan Staley: Great Video and REALLY helpful. Thanks VERY much!
BikeManBen Productions Gaming: Nice job man! I actually think the lines between the old paint and new
paint look sweet.
Brian William: where do you buy the carbon sheets, vacuum bags, etc?
MrHifonics: Man your doing all this for a mate, you are a good mate. He could've at
least hold the camera for you? THUMBS UP!
Pulido Brothers Racing: Wow mate, you did a great job with that repair, apart from the paint giving
it away it doesn't look like there was ever any damage at all. Kind of
makes me more weary of 2nd hand carbon frames now though.
justinssite: Thats the one that keeps me away from cfiber. it breaks way too easily. Ti
is nearly as light, and much less breakage.. might not be as stiff though..
Mark King: Thanks for the Comment! I generally don't like to sand more than I have
too. Mostly in fear that sanding will compromise the structural integrity
of the bike. It is so easy to get carried away and sand too much.
hopsyn: Ok thanks I thought you applied the epoxy to pre preg carbon and layered
jibedaddy: By the time I go buy all the things needed to do this project, plus double
your estimate of 5hrs due to being a total newb and slow, I'd chew up 2
good riding days and still have a bad result. I'll pay my $250 and be sure
it is done right. Otherwise, good videos to educate thyself on the carbon
layup process. PS: The other thing is factory warrantees. Had Trek do a
couple repairs + paint for free.
Mark King: Thanks! Besides becoming and engineer?- Here's how I managed. I copied the
geometry from another bike. Once geometry was drawn out, I drew the rest of
the frame. I did a lot of research on what components and hardware I would
need and then incorporated that into the design. I looked at a lot of
broken frames to determine the thickness I then added about 50% more
structure for safety. Then I just went for it. Check out my site or channel
to see the two bikes tutorials I've done.
kaimbell90: You should do a full suspension mountain bike frame as your next project!
Ricky Johan: good job!
maen titi: dear friend i have trek madone 5.2 and i got crack i really dont know how
to fix it
MxAxRxK: this was helpful. i just wish you didnt fast forward through all the mixing
and laying though. is it ok to leave the broken fiber like you did? ive
seen some people cut out all the broken area. i found a carbon fiber Giant
TCR frame in the trash with a small dent in the top tube and want to fix it
and build it up.
Mark King: I love my VFFs!
Marti86: excellent job mate,good friend
Dave Kim: pretty awesome - what if you just sanded the whole bike down... and fix it,
sanded it and put new decals, would that have worked?
Mark King: Thanks!
Mark King: thanks! It'm just using regular automotive primer and paint that I
purchased at the local automotive parts store. I did find that a good
automotive urethane clear coat make for a nice finish on these bikes. I'm
sure you'll be fine with the brand of pain at your local auto store.
Christoff87: Why don't you use the life time warrenty that Trek have on all frames.
Dennis Kwok: Top job. Officially impressed.
Tom G: very very nice ;) and a good vid!
ERIC GRAVES: Mark, Great video! Was coming home from a ride. Had my bike in the back of
my truck tied down with a bungy cord, with a carpet cut under it for
protection. Bad move. Wind caught the carpet and the light bike almost blew
out of the truck. Damaged the top tube much like in your video. Really
bummed out. Need to find a person near Chicago with your skills. Thanks Mike
Mark King: @213DOGFA Dang that sucks! If you can't find anyone, it's really not that
hard to do yourself (although the majority of experts would disagree we me
on that). I just did a toptube fix on a Super-six with a tape wrap instead
of a vacuum bag and it worked out great. I'll post the fix on my website
soon. Good luck.
Mark King: @iloveebay1134 Send me an email or Youtube PM. You can find my email on the
"contact us" page of my website.
justinssite: I don't think Ti breaks are as bad, because if you Google 'broken carbon
fiber bikes' vs. 'broken titanium bikes', the images for Ti are usually
fractures and cracks with one that's broken in half. However, for the
carbon fiber query, every single one is broken to oblivion, shattered and
splintered. There is a website dedicated to broken carbon fiber bikes for
goodness' sake. I would probably choose Ti over Carbon because of the road
condition in my area, otherwise, Carbon is very appealing.
Draculynz Tan: great job.. if thats mine i wont mind the paint. thats a beautiful job.
Mark King: @aiboldayev Check out my tutorial "Carbon Fiber Bike Repair 2- Tape Wrap
Alternative" it's on my channel. I'd post a link but the comments wont let
me. If you're interested in doing the repair yourself- It's a fairly simple
process. If you need some help send me an email or youtube PM.
Mladen Sinkić: Hello my friend! I have one problem with carbon frame! Please give me your
mail adress so I can send you a photos and then you can tell me what to do!
Mark King: Thanks for the comment! If I did it over, I think I would have made a
graphic or design to cover the repair instead of trying to match the paint-
I think it would have worked out better.
Jeff B: What kind of paint do you us?
vikingfin: Hello TheProjectJunkie1 and greetings from England Can you tell me what the
benefits are using vacuum wrap over tape wrap and do you use a special
filler for carbon fiber to smooth things out. All the best and keep up the
Mark King: Me too! LOL You should give them a shot sometime. They've help me out with
all kinds of problems. Not for everyone though;-)
Travis Lyons: With the extra layers, I'd be curious to hear the differences in frame
tones and to know how/if this had any effect on the ride quality. I'm sure
it probably had some effect on the frame's dampening characteristics.
Really awesome job! I don't have any intentions of doing any carbon repairs
on my own bikes... But very interesting to watch the process
Mark King: My repair is mediocre compared to some repairs. I've seen repairs that are
completely unnoticeable. However, I'd be more leery of little dings in the
frame where you can see a little chip on the outside and who knows what's
underneath. If you buy a 2nd hand carbon frame be careful!
Mark King: @lukey4 I got my carbon fiber from CJ Composites on ebay their CJ epoxy is
really Resin Research epoxy re-branded and they sell it in small
quantities. You can also find small remnant pieces of carbon fiber at
decent prices if you search on ebay. Otherwise, there are a ton of places
you can get carbon fiber and epoxy from.
Mark King: The bottom of the tube wasn't broken so I didn't worry about overlap there
and I knew I was going to fill and paint so I didn't worry about bigger and
smaller sizes of carbon fiber. Thanks for the comment.
Billy Wu: your friend must love you even more.
Mchiko: Really awesome job, if it was my frame I wouldn't even spare a thought
about paint mismatch, would be just glad to get back on the road.
toowaker37: Very educational to see the process from start to finish. You did a really
great job. I wouldn't hesitate to ride that frame after the repairs. I'd
probably replace the front forks though, because if that goes so does your
Mark King: Thanks for the tips. I made sure that he frame was sealed before using the
vacuum. If it can't be sealed I just do a compression wrap. You should do a
video to share with us your knowledge. Send me a video response and I'll
