Hoping the collective wisdom can set me straight here…
I removed the chain guide on my 23 Levo Carbon Comp today since SRAM indicated the 36t chainring won’t work with the OEM chain guide.
When I removed the frame bolt, of course I dropped it on the ground. I found the bolt and a very thin silver washer on the ground.
To reinstall the bolt, I ended up using:
1. Part of the chain guide with a pin that fits into a little the frame (named “chain guide back plate” in the manual)
2. The thin silver washer
3. The frame bolt (which apparently gets torqued to 18nm according to the manual?)
I was very nervous using 18nm torque on my carbon frame, especially since I wasn’t sure the assembly was correct.
The manual shows that there should be a 2mm washer against the frame, but I couldn’t find such a 2mm washer anywhere on the ground.
I’m attaching a diagram showing the part that I couldn’t find. It’s part J in the diagram, circled in red.
Do I need the washer labeled J?
Do I need a chain guide?
What’s the correct way to reassemble the frame bolt if I don’t run the chain guide?
