Hi and thanks for the reply.
I haven't solved it yet.
Maybe I can file or saw off the three corners.
I'm looking forward to an answer from riderever and hope you'll give an update.
I was just as annoyed because it was clearly visible on the website.
And the second difficulty was finding suitable olives.
The problem has now been solved BH90 fit both the lever and the saddle. Sram stealth a majig olives also fit.
The support/sales representative from Riderever was not helpful. He basically just said there are two versions of the lever: one for Di2 and one for SRAM AXS Wireless Blips. He simply told me to buy a new lever compatible with SRAM AXS Wireless Blips… (Of course, mate.)
I pointed out that there’s no mention of this distinction anywhere on their website, but he more or less ignored my email. Instead, he mentioned they have a distribution center in Belgium. I asked for the website or shop details of that center, but he hasn’t responded yet. I’m pretty sure they won’t have both lever versions listed there anyway…
So I’m just moving on from this because I don’t want to waste any more time with these guys.

I’ll fill the cutout with epoxy resin (up to the level of the 3 corners) and then glue the Blips on top. Honestly, it seems like the cheapest and easiest solution to the problem.
