Are there compact chainring options for SRAM axs cranks? I can't find ali cranksets that fit all my requirements (165 or 170mm, 50-32 or 48-32, powermeter, reasonably light <700g). Even on a budget the most appealing option is shimano 105 with a 4iiii left side, often goes on sale for 200€, which makes the total crankset with PM around 300e but an alternative could be SRAM rival with powermeter spindle, even cheaper at 260ish but with rings designed for 10T start cassette (and for their flattop chains?). Are there 50-34 107BCD that don't break the bank and not made for flattop? Or should I stick with 105+4iiii left crank?
Have you looked the Xcadey cranksets and power meter? They're decently budget friendly. Mine for the crank arms alone are about 420g. The spider is around another 100g or so. I've been running mine 1x, so I'm not sure how much 2x chainrings might add, but in total the crankset weighs in the ballpark of 600g (I don't exactly remember). They even come in 160mm if that's your jam.
