First we’ll start with the bottom brackets. For a press fit bottom bracket you will need a bearing press. Lightly grease the frame with a carbon safe grease. Taking note of the inner sleeve mark-ings (left and right) and push one side in. Now push the other side in.

2 / 15

For a threaded bottom bracket, lightly grease the bottom bracket threads. Thread the cups in, again taking note of which side is drive and non-drive (it is marked on the outside to the bottom bracket cups). Tighten up the cups to 50Nm.

3 / 15

Grab the left hand crank arm and make sure the bearing preload is wound all the way into the crank arm. Slide the crankset through the bottom bracket.

4 / 15

You would have noticed that your bottom bracket came with some spacers. You will need to work out what spacers you require via the SRAM instructions.

6 / 15

For this press fit setup we will have to use a 2mm one.

7 / 15

For our threaded bottom bracket we will have to use 4mm one.

8 / 15

Lightly grease the splines and thread on the right hand crank arm.

9 / 15

Tightened the crank bolt to 54Nm.

11 / 15

Gently give the right hand crank arm a tap. This will slide any slack in the system to the non drive side.

12 / 15

You should now see a small gap between the bearing preload and the bottom bracket.

13 / 15

Tighten the bearing preload to remove this gap. Do it just enough that it takes up the gap and still spins freely.

14 / 15

Tighten up the pinch bolt using a 2mm Allen key. You only need to tighten it so the top edges touch.

15 / 15

Pop you pedals on remembering to use the pedal washers.
