I am curious if others that have a VB-168 are running wider tires and what improvement (if any) came from changing to wider tires. Is this a more stable or comfortable ride? Do 28 and 30mm tires fit within the fork and chain stay? I currently run 25mm but wondering if there is a benefit to going with wider ones.

I've recently received a VB-168 and have a problem with the seatpost hardware. I've looked at your pictures and it seems correct, but can you tell me if there is any gap like mine has?

Have you tightened the saddle bolts to spec and there is still a gap? Could the metal piece have been bent slightly so it is not sitting in that groove properly? I looked through some pictures of mine and it doesn't appear that there is a gap there.

The weather is warming up and I have been able to get out for a few more rides. The bike is fast and handles great!

There is however a clicking coming from the BB area when I pedal. I am trying to determine what is causing this so I can get rid of it. It starts to get annoying on longer rides. Other than that, no issues .

I attached a current picture as well.

It is great now. I actually added more headset spacers to bring up the bars (as you can see in the pictures). I also have a 90mm stem so that shortens it up some. That is the main reason I switched from the integrated bars to the stem/bars combo. The reach was a little long for me.

I have had the bike on the trainer for the winter. The front wheel has been holding up fine with trainer use. There will be some warm weather this week so hopefully I can get back on the road for some more testing. I will update once I log a few more rides. I will also get you the wheel weight (front & rear).

I just received my VB (separate) stem and bars. These will replace the integrated bars that are currently on the bike. First impressions are that they are stiffer than the integrated bars. I will update with pics/thoughts once I get this combo installed (which requires re-routing cables through small bar spaces )

The bar/stem combo has been installed. See attached pictures (sorry for the bad pictures. it is connected to my trainer currently). I decided to externally route the cables on this combo because of how difficult it is to internally route them. The holes are very small and difficult to work with (even more difficult than the previous integrated bars). This may have had something to do with the fact that all cables were already cut to length so everything was more difficult. I think this option will be good for future maintenance though.
I cut the top headset spacer to allow the cables to be internal until the stem. I was also able to connect my quadlock mount to the bars which is a big plus (the fully integrated bars are not round so this can't be done).

After getting the stem/bar combo mounted, I don't think there is any difference in stiffness between the old and the new bars. However, I am on the heavy side at 220lbs so some flex is expected. Overall I am happy with the result.

My brake calipers were already connected to the hoses, so I didn't want to disconnect those. I ran my rear brake from back to front (afterwards I realized that the brakes were pre-bled so I am glad I did it that way) and slid the foam tubing on from the front of the frame down the downtube. *By pre-bled I mean that they already had fluid in them, so when I cut them to size and inserted the fitting, I didn't need to bleed the brakes.
The front brake hose I sent up from the bottom and added electrical tape around the steerer to keep that in place.
The rear derailleur I ran from the back to front as well (and slid the foam tube on after).
The front derailleur was the most difficult. Had to run that down the downtube and get it to seat into the frame mount for the cable housing down by the bottom bracket. It was difficult to get that lined up without seeing it.
Once all of those were in place and poking out where the bars connect, I slid all of the spacer rings over the hoses/cables, ran the hoses and cables through the bars, cut to size, connected, and was done (I realize that probably sounds like it went smoothly...I did have to redo it once I realized I forgot the headset spacers the first time ).
