Hi everyone, today I started assembling my build, but I’m having an issue with the bottom bracket. As shown in the photos, with a SRAM Red 22 crankset (53/39 chainrings) and a BB68/73 bottom bracket, when used without spacers, the crankset sits about 1 mm away from the chainstay. When I use a 2.5 mm spacer, the distance to the chainstay increases to 3.5 mm.

However, in this case, when I torque the crankset to 30 Nm, it gets so tight that it almost doesn’t rotate at all. On the other hand, without the spacer, even at 35 Nm, there is no binding and it spins smoothly.

Has anyone else experienced this issue?
By the way, I measured the SRAM Red 22 crank spindle length as 107 mm.

Did it come with two of the c-rings? Mine did and they were ever so slightly different sizes - when I changed to the other one the gap disappeared

hi Mine only came with one C-ring, not two. So I didn’t have another one to try, and the gap is still there,, there was a 0.9 mm gap between the headset and the spacers caused by the C-ring. I spent about 4 hours sanding it down, and now the gap is reduced to around 0.25 mm.

Hello everyone,
My Spcycle SP R088 frameset was delivered about a week ago.
This morning I started assembling the bike, and as you can see in the photo, the bearing cover doesn’t sit completely flush with the fork’s crown.
Am I doing something wrong or missing a part?
