Does anyone have experience using the Fibre-Lyte Lightweight 2 chainrings on a Sram Red Exogram crankset? I contacted Fiber-Lyte and they have no experience with this combination.
My concern is shifting quality and the hidden chainring bolt on the back of the crank arm. Durability is not an issue since it will be going on a limited use climber. Thank you in advance for any and all of your expertise!

I've got both but haven't got round to fitting them yet (it's planned for this weekend) will update with any fitment issues

Not sure about the sram red crankset, but I used their rings with a zipp vumaquad. I ended up needing a couple of extra spacers to compensate for spacing at the hidden bolt and fiber lyte provided those at no charge.

Maybe you spoke to someone different or maybe they forgot? I'm sure there is another user who has posted photos of this combination too.

Octaramps are one of the lightest options apart from Fibre-Lyte. Extralite's own crank uses pretty much the same hidden bolt as new SRAM road cranks, so their chain rings are another good option if you're using 110 BCD.
