I have built Bxt 145 recently. Bought it on Ali. Size 58. Pretty heavy, but I really like the looks. Frame, bottom bracket, rear through axle, UDH, front derailleur mount bracket weighs 1,500 grams.

What was the total weight of your build?

Looks great Adrian - would you mind letting me know your own dimesions(!) - height, etc - looking at a 58 and wondering how it sizes up in practice.

8,9kg - Sora groupset, Tanke semi-hydraulic brakes (heavy, but have strong stopping power), one bottle cage

Looks great Adrian - would you mind letting me know your own dimesions(!) - height, etc - looking at a 58 and wondering how it sizes up in practice.

188cm, 89cm inseam. Was riding Triban RC500 XL size before. Both bikes are on bikeinsights.com so it was easy to compare geometry of those bikes.

Hi there, from my side I did not recommend this frame. I had problems with slack on headset (too short bearrings). You are not able to proper mount front derailleur mechanic ultegra r8000 because it's rubbing against own cable armor and can not change for little gear  :'( . cracking carbon around saddle post. There is no EPS moulding and from I read on forum there are better frames in that price.

Can you post some pictures of your issues? How bad is that seatpost crack?

I got my Pro-145 a few weeks back now. I got it in gloss black as I was intending to paint it myself.

I ordered a 58 with 120/440 handlebar - I'm 6'5" so I know I'm on the limit but geometry charts suggested it would be ok though I have a fairly large spacer stack (55mm) under the handlebar. BB to top of saddle height for me is 83cm.

I received my frame in line with agreed dates. It was well packaged and everything was present. The paint it comes with looks smooth and seems tough and durable (small knocks with tools during the build didn't scratch it).

The build was pretty smooth - the easiest 'direct from China' build I've had so far and at least as good as any more well known brands. I had no issues getting cables through the seatstays which has often been an issue with other frames I've built.

Fitting all the cables in the handlebar/steerer as a fully integrated/hidden cable build was a pain but that's normal for any bike with this design and again, the same as branded bikes I've built - essentially the price you pay for a lovely, neat looking front end.

Once built up, it looks fantastic so I was looking forward to my first ride. The only issue I had was that I had greased all the seatpost/saddle fixing parts and that seemed to slip quite easily unless done up very tight. I stripped and cleaned the seatpost and used carbon assembly compound (designed to stop slipping) and it's been rock solid since.

In terms of ride, I've built it up with Ultegra, aluminium wheels with 32mm GP5000s and straight away I was taken by how smooth it felt - I did think it might be a bit harsh given the chunky looking design and tubes but it was at least as smooth as the other bikes I have, maybe even more. It handles perfectly - no issues climbing, descending and it's nice and quiet and smooth.

One caveat is that the headset has come slightly loose the first couple of rides - I've now used some of the aforementioned carbon assembly paste so we'll see if that helps keep everything together. UPDATE - Used assembly paste on the steerer bung and the headset hasn't come loose since despite several rides on my local roads which are pretty bumpy in places.

I'm very happy - looking forward to many miles on it.

Can you comment weight on the ultegra build?

Build my size M BXT 145 frame in glossy transparent blue with Ltwoo eRx, XMCarbonspeed aero 50/60mm wheels on 30mm tyres and managed to get the system weight down to 7,524 kg including everything mounted on the bike.
Without pedals, bottle cages, sensors or rear light (usually advertised when selling fully build bikes) its at 7,05 kg.

The build is still in a somewhat affordable range of about 3200 € total.
Pairing up the quite heavy weight of this particular frame with my choice of components is probably not the best idea when going for a lightweight build. But hey, the bike looks dope, drives nicely and is still pretty light.

An alternative for this frame would probably be the Spcycle R065 - with similar geometry (R065 has a slightly longer wheelbase) but about 250g lighter for the frameset.

In my case the BB area is slightly rubbing on the P505/P515 powermeter even with 2mm spacers applied... so keep that in mind when going for magene powermeters.

I had some issues with the seatpost slipping on the first rides. But after thoroughly cleaning the seat post itself, the clamp and the inside of the seat tube - so every contact surface upon torquing it up - that issue is fixed.
Been riding for about 3000 km now and there is nothing to complain about.

here a pic before swapping the handlebar (currently running the cheap AE Kocevlo version on here to test 360x110mm)

Hello.
I just bought this frame but the inside of the fork is terrible.
I can´t even run the brake cable.
I´m chatting with the seller to give me a solution and I will let you know.
Here are some pics.

Pd: I have a Velobuilt TT-023 and the fork had very simmilar issues. Maybe there is a problem with the mould desing?
