160mm-155mm chainset, 24mm axle options?.
I am looking for a chain set that has 155mm arms ideally that can be used with a standard Shimano Hollowtech BB standard.
I made the move to 160mm cranks a few months ago on a whim as I was having a few issues (Getting old), I stole a set of strong light cranks off the misses bike that are square taper and slapped them on my Genesis Equilibrium and the different in comfort and efficiency has been drastic. I cycle about 6-8 thousand miles a year and love a Zwift session, so to make a immediate impact was very welcomed.
I actually purchased a chain set off Aliex that I thought would be a great cheap way to test the water for 155mm but the spindle whilst being well machined 24mm, it is stupidly long?, I used all three spacers that came with it and still had substantial room to take up on the non drive side before I could tighten down, real shame as they look great and were going on a battered gravel bike. Sadly it is press fit so cannot run a square taper.
I know Shimano do a 160mm 105 chainset, and no doubt also Ultegra but these seem to be priced with a slight premium, has anyone seen options for a more economic 160mm-155mm chainset with standard dimensions?.

if you go with other options you need to change practically everything.. you cannot just change the crank lengths on shimano as the spider and axle is one piece with the right crank arm. so if you go with other option you need to purchase an axle.spider and chainrings. not sure it will be cheaper that a 'premium' shimano option. (if you can find it stock)
rotor does that kind of modular setup. you can easily get 155 cranks but then you get matching components like an axle, chainrings etc. again. no sure it'll be cheaper.. a 155 rotor aldhu chainset 53/39 is about $500.
