Senicx PR4 cranks

[PLA]

Does anyone have experience with Senicx PR4 cranks? The 24mm steel axle ones. Curious how the shifting is with those one piece chainrings, the stiffness of the system and durability. Putting out a modest 1600W in a sprint and not sure if they'll hold up over time or not.

Trying to build a full Chinese component bike and these are on my shortlist..

I have the chainrings (not the crankarms) and I think they're great. I have them mounted to praxis Albas. Not a lot of basis for comparison (and an even more modest 1200 watt sprint!), but they're a hell of a lot better and way cheaper than the Praxis chainrings. They seem pretty durable and shift just fine.

I have the 29mm aluminum spindle ones with 50-34. They haven't broken at a lot of 1300w sprints or a few peaking over 1500w. I've taken them off to replace the bb and there wasn't noticeable wear on the aluminum shaft. I assume the steel will do better.

I don't know about the PR4 but I am a fan of the PR2. Using different spider. I now have access to sram red chainring that aren't expensive and shifts smoother than the ones that came with the cranks

Awesome, they look good.
