Do they still have the factory barbs installed or have you cut them? I had to remove the factory barbs from the hoses for my FM336 build with integrated handlebars. The barbs ended up keeping the hose from bending tightly enough to route through the bars and out the holes for the brifters.

XMCS needs to stop putting this horizontally cut in half logo on wheels but especially the frames. Not only is it a bad copy of others ideas, but its also really weird looking.
This is working for Zipp and others because everybody recognizes them anyway and its their style. But half of XMCS reads more Like "AIVILS" in a spacy font.

It is the most popular decal choice...

Can someone confirm bosses have been added under the downtube on the updated version ?

take a look at this picture，these are the updated molds.We've upgraded to 48T, compatible with GRX 50/34T. However, the website still defaults to 46T when placing orders. Please contact us if you need the 48T version.

Thanks Lily but I was not referring to the chainring max capacity but to the bosses under the down tube to put a third bottle cage / bento box or whatever !

It's not included by default, but we can add it if you need it. Please let us know when placing your order so we can arrange it for you.

Is there other custom possible when ordering ?

Are there any pictures of a size XS frame/bike?

Got mine out for a first ride - couple of hours on mostly uk singletrack, with a small amount of road. For context the route is perfect for a hardtail and only slightly slower on a full sus xc mtb. Lots of short sharp climbs and technical descents on varied terrain - from stony gravel to tree-route mud and even some sand. A good portion of it is bumpy as hell where horses have made mini moguls. So all told it's pretty unforgiving and when I've done it on my carbonda 505sl with 44mm tyres it has been uncomfortable as hell and pretty sketchy.

The bad news is I crashed. On the bike's first outing. Not ideal. Haven't stacked it in about 3 years either. Puppy ran out in front of me it was run over dog or wash out on a stony gravel corner. Thankfully the bike was fine. The maxxis severe tyres I had on might have had something to do with it - first time using them and they didn't give loads of confidence. But tbf they're designed for the muddy stuff.

The good news is the bike rode great. Really assured handling, comfortable and no issues at all. Obvs without a dropper descending isn't quite comparable with my hardtail (which has one), but otherwise the bike didn't feel any less capable than the hardtail on the route.

I really like the ergonomics of the drops - they flare out and then straighten up again, which gives a great hand position. Obviously can't really make objective claims about how fast it is, or even comfort. But I can tell it's going to be a great bike to ride and a lot of fun to play around on.

Oh no， I hope you're doing okay !

I made an out front that roughly matches the 2 bolt pattern on the gravel bar. The front bolt is a little angled. And it's adjusted for the size small head tube angle.

It's just compressed carbon fiber and uses the parts from an AliExpress mount. It bolts through from the mount puck to the GoPro mount. Here's the file if you wanted to make you own or print it from metal or or just take the dimensions. https://cad.onshape.com/documents/9a8966dd923077790a7317b0/w/80f5320a8d866c1a15872e45/e/fc8def4be478ee5ec0b13cb4?renderMode=0&uiState=6adaf9ddc1e89902c971224c
