Is the C shim needed? I asked Chris where to put it and he just told me it's optional. So I didn't bother putting it.

The C shim is needed when the stem is rubbing against the headtube when everything is compressed. The rubbing does not let your handlebar move freely. This was not necessary for the carbon stem but the alloy one comes just a bit more down that gives a bit of rubbing when fully compressed.

I'm looking into the BXT handlbar. Not many universal options in both the mainstream or chinese market that have an integrated stem. There is tririg and the vision metron tfa base bar. Both are pricey.

Just as the answer above I looked into Tririg from previous thread. It seems to work but the fit is not flush (does not matter so much). I am also looking into this handlebar from a different frameset.

Again not sure it will fit but I don't see much problems. If anyone has an opinion on it, please tell me!

Hello, I would like to install a one piece carbon base bar (and stem combo) instead of the two piece design that comes standard with the frame. I have contacted Chris about compatibility with the frame but he is not sure what base bars are compatible. Does someone have experience with this?

My main concern regarding of the desire for this change is the flexibility the setup now has with the aluminium stem in combination with the carbon base bar. Previously, I had the carbon stem and base bar combo where the base bar slipped and cut of my brake lines almost causing a crash during a race. I was happy knowing there was a aluminium stem comming. (The alu stem feels sturdy yet too flexible for me).

Hopefully someone can help me!

Anyone having issues with their post slipping? I'm a smaller rider so I had to cut my seatpost a large amount. I had to cut off the bit of the seatpost that had the anti slip coating on it.

I haven't even ridden the bike yet and the post still slips just sitting on it... When I torque down the bolt as far as I can, the bolt bottoms out/slides against the clamping bit, and even then the post still has some side-to-side wobble like it's undersized.

I put a bit of electrical tape around the post and now I can at least sit on the bike without it slipping. I assume the post is a little bit undersized after I cut the bit off with the anti slip coating? Anyone know what the factories apply to the post that I can do at home?

Did you use carbon gripping paste?

Hi, could you tell me what internal and external widths those XMCS wheels are and how much space you still have left in that frame with the 28mm tires?
I am looking for a similar setup but would size up my tires to 30 or even 32mm.
Thanks!
