WINOWCYCLE NEW Carbon TT Rest Extension Handlebar ARB02 and TT handlebar HB052

[Cnasta]

I have received my extension today. They really look nice. Also received the angled spacers (20 degrees) and computer mount. Will post some pictures later.

For mounting, is there a 'normal/usual' amount of torque for screwing the extensions to the spacers (guess I use 3 bolts per side).

Spacers to adapterplate = alu-alu, so guess overtorqueing isnt't really a problem there (except for stripping thread).

Would it be possible to know the distance between the holes that go into the spacers?

The vertical distance (the 2 bolts that go inside the spacers) and the distance between the holes on the left and right sides. I’m not sure if these distances are universal, but I’m looking for a part exactly like this for my bike, and if this one is compatible, I wouldn’t need to make a drawing and have it made via CNC.

I’d also like to know if it’s possible to purchase just this part.

Usually most of them are not suitable.

Thank you so much!! I will check if it's the same as mine...

Anyone has some 3d printed spacers for the hb052? I want to install lighter spacers than the alloy ones.

Will there be another version that is compatible with Sram red? Or do these also fit the blip holders for SRAM?

Received my ARB02 bars this week with the computer mount. Took about 2.5 weeks from purchase to delivery. I used the fasttt size chart where i landed right in the middle of the size large. My elbow to pinky knuckle was about 385mm. Theres probably 20-30mm of space left behind my elbow with the winow bars, so maybe i should have ordered a medium for the perfect fit.

Weight for a size large, glossy, mechanical is 492g. The computer mount is 61g with a light/ go pro mount. The computer mount seems very solid and Im looking forward to seeing how it works with my position.

Is there a comparison between the three aerobars? Would like to see the pros and cons of each to help decide.
