I been enjoying the heck out of my catrike 700. So I am finally getting around to my vb-218 build finally.


 I found a big issue... The front derailleur hanger was not correctly affixed to the frame... It wasn't shifting even before I put a chain on for the first time.  I havent even rode it! I noticed the front detailler was loose. and the rivets weren't properly installed. also there was a lack of epoxy as well. So I set out to fix that.  Drilled out the rivets. Make sure you tape around the area to prevent scratching the paint. I didn't do that. there are a few scratches... grrr.


So I masked out the area  to sand that the epoxy was going to touch to  improve adhesion. I then used 1000 grit I should have used like 380 or 250 grit... I ended up also using a hobby file to get those rough spots like I would get with 250 grit.  Just use 250... maybe even 180. If you hit carbon thats too far. its easy to go right through the carbon.


While sanding away... you will have some feathering because of the height in the tape. see pic. Now just some IP alcohol to remove any oils  and improve adhesion.

Once you prepped it, You are all ready to for the epoxy.  I also sanded and used the file on the  derailed hanger. I pre inserted 2 rivets for alinement... only thing to do is mix the epoxy and slap some on.... then put the two rivets in the holes on the frame...


Put  the derailleur hanger on the frame with the two rivets to use as a placement guide and insert the remaining rivets before  you actually set them.

DO NOT use the rivet gun til all the rivets are placed!!!!

 Once all of the rivets are the holes THEN use the rivet gun to set them.  then wipe away the extra epoxy that squeezes out with paper towels. wait about 18 hr if you have the 5 min epoxy. I am waiting a few days to make sure it has hardened before I install the derailleur.

BTW if you have any questions. please ask away.

I am finally putting my vb-218 build together  and besides having to redo the front hanger because of bad rivets and no epoxy....(I swear this is the most pain in the butt build...)

Any way I was testing out seat height.. well its slipped down a 1cm and is now stuck...  to be honest It was mostly in there already because of my short legs. and long torso and xl frame(only way I can fit bikes) biggest reach/ top tube for long torso and arms and a slammed seat post for my short legs... now its too slammed!

Any ways How do I get it out??? I tried a soft rubber mallet and pulling and twisting... its just slightly moving forward and back like 0.5 to 1 mm..

what other tricks can I try?

I got the part holding up my build!!!! Just a simple part!!! Build is dead or switch all the drive train... lol Thanks much

Frame arrived, 3 weeks from order to delivery with custom colour.
All the component were well protected and the paint job is ok.
All small parts included (ex. Garmin mount support)
The only part exposed was the derailleur ha ger that is now bent.
Anyone know if the Pinarello f derailleur hanger is compatible with vbr 218 frame?

From the pictures look quite the same,have anyone experienced with that?

That looks right if its the VB frame... I got 6 of them at the time of purchuse... just in case.

Who did you get the frame from? and how much?

cant have that bumpy normal air.... also these arnt tubeless....

I have some new Continental Grand Prix 4 Bicycle Tyres for my bike build thats not even complete... and they appear to be out of round...

what could be the cause???

Is it the fact they are new or that I used cheaper tubes?

I want to enjoy my bike when its finished.

Chris from velobuild just got back to me.. it was 10 bucks to send 2 out.. I guess we will see.
