Apparently you need the wavy washer in place of the preload adjuster spacer of the current Sram22 offerings. So now I need to track a wavy washer down.

Grr... i expected things to go much smoother!

Do you know if the sram cranks need the two spacers like the hollowgram cranks do? One is 2.5mm and one is 2mm I think, those are for the bb30a fitment.
These are what I have Image

@evan.. that's the problem is I can't find one piece of official literature that clearly explains this! I definitely had way to much bearing load with the 5mm preload adjuster so I plan to get a wavy washer today (hopefully) and can get this assembled!

Do you have, or know if you need the other two washers in the photo? I would think so. I think they are more about being bb30a, than being for a hollowgram crank.

Ah, that's BB30A isn't it and not BB30? Yeah, you do need the wave washer and remove the threaded preload adjuster. You'll also need 0.5mm plastic shims to get the preload right.

Sir

Yes, I removed the preload adjuster and added a wave washer and things appear correct after the proper TQ. I did not have nor add a .5mm washer.. is there another way to check for proper preload? I haven't ridden her yet but on the stand and ground the crank has no lateral play.

Thanks again for the expertise.

BTW..

I have the derailleurs adjusted and everything installed minus the seatpost, Seat, and bar tape, and it's currently at 5.88kg.

Did you buy the crank new? Just curious for future reference that I'd need to source washers too.
What else do you need to finish?

Yes the crank was new but through Fleabay so of course it came not in original box.. it appears that Sram had changed over from the wave washer to a turn style 5mm adjuster so I don't think the crank even comes with the wave washer anymore? Either way I would recommend the kit with washer and bearing covers.

Minus bar tape, seatpost, Seat, and bottle holders the bike is complete. I just took her around the block to check shifting with a load and it worked flawless. I'm very impressed with how light she is ending up..

These are my Pedals..

Picture of wave washer... how's it look?

Image

And how it sits as if 5 mins ago just after my seatless ride :)

Image

I would like to get the Seat on before slamming the stem and to also make sure I like the position of the shifters! If my seatpost comes Tuesday I might take her out on my 20 mile loop!

Any thoughts or suggestions?

:)

The wave washer should be compressed so that the gap in the 'waves' is only the width of the wave washer itself. To me it looks like you probably should have 2 or 3 0.5mm microshims in there.

Gotcha! I will pick some up tomorrow.

Thanks again for the assistance :)

+1 on more shims, is there any side to side play in the crank?
It's crazy how much lighter your sram setup is than mine. Bike turned out great!

Ok.. I tracked some shins down from an awesome local shop. When I added one it made no difference so I used two..

Image

I also added the bar tape and took a quick shot on the scale. Fingers crossed the Seat post arrives tomorrow. Besides that all I need is the titanium bolts for the water cages and I'm ready to go!

I dig the short tape job. Too much tape is gratuitous (and heavy). Details matter!

I really dig the long reach stem and bar combo. Looks very fast and racy.

Will the tardy post and saddle arrive in time for picture day?!

Make sure to hit the DS crank arm with a hammer so that it is bottomed out on the DS bearing. Then check your wave washer preload.
