Re: TanTan TT-X21 frame
Hi all,

Have you had experience with play on your frame? If yes how did you resolve it?

I had an issue with the headset, as it didn’t matter how tight I made it,  the sort of half ring that stays in between the steerer tube and the top bearing seemed a fraction to small, causing the play that become extremely noticeable when I assembled the bike and used the front brake to rock the bike back and forth.

Cheers

Yes, this was an issue from day one. I went to my lbs and the tech set me up with a set of head set spacers. They are super thin, .25mm each. They sit on top of the lock ring, the half ring, that sits on top of your bearings. A stack of three worked for me, but I bought an FSA ACR headset awhile back, hoping to fix the problem that way. 

To make a long painful story short, I could tighten down the headset, but then the steering would bind, with the fork rubbing up against the head tube at the bottome, and the top cover rubbing up against the head tube at the top. I tried an FSA ACR headset, but that didn't solve the issue completely, but it did help. I ended up using one of the fatter ACR bearings at the bottom, and the fatter TanTan bearing at the top, along with the fatter FSA Lock Ring at the top, but I couldn't completely eliminate the play withing binding up the steering.

These spacers worked like a charm. No headset play at all and butter smooth steering. Yuo'll have to cut a notch in the spacers for the cables, but that's pretty simple, and you'll just have to play with the amount of spacers it takes. They come in different thicknesses.

Good luck!

Re: Velobuild VB-R-168 Frame
Oh okay so it was more vertical play rather than lateral play? It wouldnt be good to be wanting to turn and the wheel doesn't turn lol. What i meant by unheard of is out of how many frames bought (or so youve seen) has this problem been encountered

No, it was lateral play caused by the headset top cover not pressing down on the compression ring properly. From what I can tell from reading posts, I'm not the only one who was having the issue with the X21 for sure. From what I can tell, there might be an issue with the way the integrated headset is designed for the frame. Without the microspacers, the top cover would rub against the frame before putting enough pressure on the compression ring. Other than that, I haven't had any real issues with the frame. Seems like a solid design.

Re: Velobuild VB-R-168 Frame
Hey guys, quick update on my build, which I hope might help who still need to start:

After managing the internal routing, I realised that I couldn't eliminate the headset play without locking the steering. After quite a few trials, I realised that the problem could be that the compression ring that sits above the top bearing, is sitting too low for the dust cover to compress it down once the top cap is tightened, which result in the dust cover pushing on the frame instead of the headset (as it has downward lip), while pulling up the fork excessively. As I put some cardboard/plastic strips on top of the compression ring as spacers (didn't have nothing better on hand), it seems fine, although some paint paid the price while figuring this out.

Obvs is not a solution but I intend to redo the wiring in a few weeks, once I remove the spacers and re-cut the fork, so i'll fix all that at once with some spacer-half-ring or something. Maybe a 1-2mm extra height in the top bearing could do, need to do some research on that. If anyone has ideas, fire away ;D

Hope it helps if anyone has/will have the same issue ;)



Some of these would probably help: https://www.bike-components.de/en/FSA/Micro-Spacer-for-Integrated-Headsets-p7698/?o=300069-silver-1-1-8-&delivery_country=NL&gclid=CjwKCAjwjJmIBhA4EiwAQdCbxphutMOEaE4FZdwqrjjwKWg_931LSH2cvdmBo4OMPOphM-T1k8En_hoCA6oQAvD_BwE
