From what I know the forktube is carbonfiber with a thin alutube on the inside And I used a star-nut.

Your fist step is to measure your cup and your bearing.  According to CaneCreek, the are four bearing sizes for an integrated headset.  Take the two measurements, the OD of your bearing, the ID of your frame, then we can help you figure out what you need.  The cup in your frame is a standard off the shelf part so unless that part was made wrong, your probably just need the correct bearing size.

See below:

Thank you for the picture! I will get a caliper tomorrow and get exact measurements.

Here´s a video of the problem. As you can hear (and see?) it is possible to move the bearings some micrometers. Is there anything that I have missed? Do you need to pressfit the bearing, or should it just slide into place?

And here some photos of the bearings and steeringtube.

Thank you Carbon_dude, it seems like it will slip right in. Since I never have put together a bike before I didn´t know how it is done.

Got my package with the parts today, so its building time! Hopefully, if I´m not getting any trouble it should be ready this weekend!

Can you post a picture of the headset bearing? Not sure which parts of it might be plastic.

Since mine Stevens S7 bicycle has seen its better days I decided to build a new 29er and reuse some of the parts from the bike. Since I´m a student it was important to keep the costs down.

My choice of frame ended up in the Flyxii FR-216 19" UD matt. I liked the geometry and design much better than the IP-057. When the sum ended up at 500$ for the frame, fork, seatpost and handlebar it was a easy choice.

I was thinking of reusing the brakes from the Stevens. Since I´m going for a details in red, including brake hoses I ended up to buy a set of SLX-M675 brakes that had been taken of a new bike for 80$.

I got the frame on my door in Norway 7 days after I ordered it from China, with free shipping. I also bought Shimano MT66 wheelset with tires used once for 240$. The wheelset is the first one to be upgraded when I can afford it.

So I ended up to just reuse my drivechain(casette, crank, front gear and rear derailleur) and disc brake rotors from my old bike. The total cost will end up around 900$.

Following is some pictures of the receieved frame and accessories. Rest of the parts are scheduled to arrive in the coming week. So I hope the bike will be ready in 2-3 weeks.

A question I`ve noticed:
- The headset has plastic bearings. How durable is plastic as material in headsets?



 

When I first got mine I thought the same thing. Feels odd/weird after having alloy frames for so long.

Sounds weird when you tap on it too.. Like, am I seriously supposed to expect this to support my body weight? lol.

I´m glad it´s not only me that felt that way. Though it was just the fork and accessories that came today since the package was so light.

Then it´s just to order the rest of the parts and start the build! I will make a build thread if I remember to take enough pictures

Just got my FR-216 UD matte frame from Flyxii today. It was suprisingly light, and i felt like plastic Of course am I a little skeptical about chinerframes. But can anyone else confirm the plastic feeling when touching the frame? I have never touched a carbon frame before, so I don´t have any preferences.
