*UPDATE*
I have a little over 700 miles on the Senicx PR2, 165mm, 46/30 crankset right now. The bike gets ridden for 3/4 - 1 hour sessions per week on the trainer stand and another 40-100 mile ride each weekend.
Its been on the road, the bike paths, gravel trails, dirt roads, and mountain bike single track. I've climbed and descended some very nasty grades with it and even jumped the bike a few times.
Everything is going smoothly, nothing has wiggled loose nor shown any real wear. No creaking, no notable flex while riding.
I give the thumbs up. Its pretty dang light and has been shockingly strong so far. Granted a weigh a whopping 120lbs so even with intentionally beating on the bike i'm not putting much force into things compared to someone of more substantial size.
The crankset is paired to an 11speed hydraulic Shimano 105 drivetrain that was nearly new when the bike (2016 Kona Rova Aluminum) was built in early January.
It'll get another 100 miles or so put on it before I put it through The MidSouth100 on March 10.
Also, It seems the 3 bolt SRAM chainrings will fit onto this crankset, so I've been searching for chainring mounted powermeters for it. Just haven't come across any powermeter spiders that will accept a 46/30 setup, in case anyone has a source or knows the special search terms to find them.
