I recently bought a second hand KCNC Silverbone crankset but it came without the M18 x 21mm crank bolt washers. The instructions say "Attention: Washers must be used with K-type MTB cranks!" so I don't think it's a good idea to leave them out. I've contacted KCNC for a replacement set but received no reply. Can anyone tell me what thickness and material they are supposed to be? And any ideas where to get some?

The crankset also came without the 2.5mm rubber o-ring or any 2mm spacers so I have ordered those from eBay.

Here are my weight measurements:

Small ring bolts: 4g
Main ring bolts: 7g
Crank bolts + extractor: 32g
Left arm + preload collar: 147g
Right arm + spider: 195g
22T: 16g
32T: 31g
44T: 73g
Cranks total ex BB: 385g
Cranks + rings total ex BB: 505g
Bottom bracket: 195g

Have you look at Fairwheels website? They have a decent range of KCNC stuff?
I guess there's worse hobbies than making a bike light? Right?
