Does somebody know of cross/in-line/sub brake levers compatible with SRAM Apex? Could the Shimano GRX sub brake levers perhaps work?
See https://bike.shimano.com/en-EU/product/component/grx-11-speed/BL-RX812-L.html
Thank you!

3Shimano uses mineral oil in their brakes. SRAM uses DOT fluid. The fluids and components from the systems can't mix due to seal <-> fluid incompatibility. More importantly, why do you feel you need/want sub-levers?– Paul HCommented Mar 29, 2023 at 19:05

Hi Paul. Thanks a lot for the reply. The fluid incompatibility is a pity, indeed. I had read about it but was not sure if the incompatibility was both ways. I want sub-levers simply for safety (and confort) reasons. When having the hands on the horizontal bar, it takes half a second to switch position and be able to pull the brakes. Half a second is a lot when it comes to avoiding a sudden danger, hence my interest in sub-levers.– Christian VincenotCommented Mar 30, 2023 at 13:30

My point is that sub levers aren't a good way to stop in an emergency. It's just a bad/unstable position for your body to brace itself for an emergency deceleration. I think your money would be better spent paying for a professional bike fit such that the hoods of your existing drop bar levels are a comfortable enough to be your default position on the bike– Paul HCommented Mar 30, 2023 at 14:48

I get your point, although I must say that, for having had a cyclocross bike with sub levers 25 years ago, I found it pretty decent at braking back then. Of course, if I had to choose where to brake from, I would go for the hooks, obviously ;-) But when an upright position is useful (i.e. resting, or cycling over rough terrain), I think gripping the bars is a reflex, is it not? But I take good note of your suggestion. You are right, I could perhaps simply switch my stem to bring the handle closer/higher and allow for a more upright riding position from the hoods.– Christian VincenotCommented Mar 30, 2023 at 17:15

Found this, but Hope just told me that they will never mass-produce this prototype: road.cc/content/tech-news/…– Christian VincenotCommented Mar 30, 2023 at 17:19
