Not required on 30T
These are not required for the 30T. It just depends on the length of bolt you have. If you had the right length bolts and added the shims, then your bolts would be too short. In my case, I used the bolts from the granny gear. They were 8.5mm long, exactly like the RaceFace chart says. You can check RF's site for the compatibility chart.

Hope this helps others wondering if they need these.

Perfect fit for my Shimano Alivio cranks
Perfect fit for my Shimano Alivio crankset. Converted the triple chainring to single using these shims/spacers. The fit and finish matched perfectly, and installation was easy. Purchased the RaceFace narrow/wide chainring with the RaceFace Chainring Bolt 4 Pack.

Race Face Chainring Shims
Picked these up after my homemade one-off chainring bolts backed themselves out and had to do a trail repair to get home. They take up the slack nicely for on the 1x9 setup I'm running and look nice to boot.

Cleanly converts your triple or double chainring setup into a 2x10 huh?
Biker Bryan on Apr 19, 2017
BEST ANSWER: Well, if you aren't using a big ring or bash ring on you old 3x cranks, these just make it look cleaner is all. Looks like the spider on 2x cranks. Quite simple, clean and clever.
Will these work to allow me to remove my big ring on my shimano setup? Or are they only the right thickness for race face rings?
Mario N on Apr 14, 2017
BEST ANSWER: I Used these shims when converted my 3x to a 2x,I used it on a carbon noir crankset,I believe it should work for most 3x cranksets ,its basically a space filler or washer but gives a finish look ,worth the money.
I would buy this product, could you help me?

BEST ANSWER: They move the chain ring over to center when convertingoing a 2 by 10 to a 1 by 10 set-up. Rear deraler replacement is recommendation if you have a long cage.
