Sorry for late reply,
this is light between frame and the 38t chainring
It's about 2 mm. Hope this helps

it's very odd that you can't fit a bigger chainring on there. it is supposed to fit up to 46T 1x.

I have this frame too.

Single 42t chainring do fit if you use a flat chainring (no offset) with a road crankset. this will give you a 47-48mm chainline that works perfectly with the 142x12 rear (mtb 1x11 chainline is 49mm as per Sram).
Sram CX1/Force1 chainrings have a 45-46mm chainline that works with the pre-disc 130mm rear hubs of the road bikes.

2mm will not be an issue in any case, but you can definitely use a 42t in this frame.

Here is mine in Sardinia one month ago:

i wasn't speaking of direct mount rings, just 5 holes rings with no offset bolted on a sram road crankset with spider. no experience with direct mount rings on this frame.

yes, 700x35c tires (but they measure wider on my mtb rims)

@benex thank you! i have those, but that doesn't give me any specification on the thread size so i can buy nicer/lighter axles.

Hi,
I built a CX39. Too bad it requires to run full length hose.
Built with a pair of 650b 30mm/30mm rims (1299gr) and tubeless WTB Horizon 47c. Hybrid brakes and 105 R7000 groupset.

It comes down to 8.7kg with bottle cages and road pedals and handlebar tape (not in the picture). Would go 8.6kg if I had chosen a classic handlebar/stem instead of integrated handlebars.

Size M with 100*400 handlebars but just slightly too big for me (181cm). And the headtube is a bit too small (would have loved 10mm longer headtube).
I used some tubular glue (left it dry 1 night) on the seatpost to prevent it from sliding (but put too much of it so for now I am a bit stuck if I want to lower the saddle. Would need some time to get it out. I'll try this weekend. Should have done this only over 7cm, not the whole length, about 15cm). I tried a small sheet of metal (from a cane of Coke) but couldn't make it work even on stationary position. To me, the tubular glue is the best option but use it with caution (5cm at first and see the results). I didn't try carbon paste because it has never worked great for me (especially when the use indicates lots of vibration)
Regarding my SRM cranks, it's kind of a pain in the a** because the star is too big and it requires a small shim so that it doesn't rub on the frame (and it's still very close to the frame). I will probably need to run another crankset on the long run because the shim makes it slightly shorter on the left side and I don't want to lose the left crank arm while riding.

It will be my everything bike since I don't ride that much on road and honestly the 47c's feel ok on road too.

I glued a little piece of sandpaper on the trapezoid piece of the clamp that get pressed on the seatpost. it works great. all the clamp mechanism can slide in&out with the seatpost so it does not rub the seatpost itself while adjusting.

the space inside the size S frame is so small, none of my existing bikepacking frame bags fit!

does anyone have a recommendation on nice compatible frame bags with size S frame?

Has anyone managed to find decent mudguards/fenders for these frames? I’m assuming clip on fenders are the only option but I haven’t had much luck with the ones I’ve tried in the past.

I’m considering buying a frameset for a gravel/winter bike. Sadly it will be used 98% on the road as we don’t have many trails/gravel roads around where I’m living but I need studded tyres for road riding in winter so figured this will be the perfect addition to the stable.

Hi all,
this is mine. Image2018-06-12.jpeg  I bought the frame from BXT  (was a little cheaper than tideace) and built with Rival/Force1(mixed) and handmade 27.5 wheels (mavic xc421 rims and novatec 791 hubs)
Unlucky the 42 teeth chainring didn't fit and i had to go lower with 38. If i knew that i surely went on double crank in the front ( i like the Campy Potenza HO 11 )
Other issues are that BXT doesn't provide front thru axle so I had to try some from other aliexpress sellers, and the .......    fu.....ing slippery seatpost 
I'm looking for a valid solution yet. Any suggestion is apreciated
Luckly at this time the bike runs good
./b

 

Hows the bike going for you Ben? I just got the same one from BXT and just waiting on a few bits to polish her off and get out there riding...

 

45427200_2230805880573424_7198875395851026432_n.jpg Mavic CrossRide 27.5's with 2.1 crossmarks on them. 70psi on the road should be fine and drop them for the trails. My girl is going to sew up some frame bags for me, and itll be my weekend disappearing act 😉

I am really interested in the workswell WCB-R-125 bike and love the geometry except for the laid back seatpost. Has anyone looked for a non setback seatpost? Does a 3t charlie seatpost fit this frame? If so that would be great, otherwise might I be able to fit a 27.2 or 31.6 seatpost into the frame with a cut off piece of the current seatpsot post.

That's a good question.
I would really like a non setback seatpost on this frame, does anyone know if a 3T Charlie would fit?

I never heard back from anyone so didn't buy the frame. Maybe if someone can confirm I'd look at it again.

The general shape of the tube is similar but I’m not sure if it’s exactly the same. The binder wedge is also very similar to the 3t version. Sorry that’s the best I can tell you right now! I’ll hopefully be testing it soon.

Does anyone have a link to purchase the stock 3t exploro seatpost with elastomer head?

Pues sería interesante, por que ganas alcance con tija recta, y te quitas el problema del deslizamiento.
