BXT SL-115 - First build
I started this build in January 2026, and I have now reached 2,500 km on it. At this point, I am very happy with the bike.
At the time of purchase, the frame didn’t have many sales yet, so I was a bit skeptical. However, the geometry and overall look appealed to me more than an aero-style frame. For the rest of the parts, I decided to keep the cost as low as possible, while still choosing components with enough previous orders to feel confident that they would perform the way I wanted.
The entire build went smoothly. After three evenings, the bike was pretty much rideable. However, it was initially set up with an Ltwoo R9 groupset, and I spent a lot of time — probably around 1,000 km — trying to dial it in before eventually giving up.
With the rear derailleur, I believe a part may have been missing when I received it, as the B-screw didn’t seem to have anything to catch onto. The front derailleur worked, but felt inconsistent, most likely due to my own setup rather than the component itself.
Either way, I decided to replace both the front and rear derailleurs with Shimano 105. Even then, the shifting still wasn’t great, so I rewired the entire bike using original Shimano cables and housing. This made a big difference: the cables were much easier to route, and the shifting is now spot on.
The bike is set up with the following components:
Frameset: BXT SL-115, including fork, cockpit, seatpost, bottom bracket, and headset
Saddle: RYET 3D Printed Saddle
Crankset: Senicx P3, 165 mm
Chainrings: 52/36T
Cassette: 11/34t Shimano 105, 11-speed
Chain: Shimano 105, 11-speed
Front Derailleur: Shimano 105 FD-R7000
Rear Derailleur: Shimano 105 RD-R7000
Shifters: Ltwoo R9
Brake Calipers: Ltwoo R9
Brake Rotors: SRAM Paceline, 140 mm rear and 160 mm front
Wheelset: Elitewheels ENT 2.0, 55 mm
Tires: Continental GP5000 S TR 32mm
Tubeless Setup: Tubeless
Tubeless Valves: Bucklos 80 mm
I also have a Magene PES P515 power meter that I am planning to install. Since I live close to the coast, it is almost always windy. Because of that, the 55 mm wheels can make the bike feel a bit nervous in crosswinds on certain days. This has made me start looking into shallower wheels. I still don’t know whether I will go for another pair of Elitewheels, a different set of Chinese wheels, DT Swiss, Zipp, or ENVE AR40.
For the past 1,500 km, all I have had to do is check the tire pressure and go out for a ride. The bike is very comfortable and feels good on the road. Overall, I recommend this frameset.
