Wanted: 150-160mm track cranks (ladies, anyone?)

Hello,
I have recently started investing my time in a bike fit and apparently I need cranks much shorter than a bigger person would. Looking for options with a crank arm from 150mm to 160mm. Heard rotors make cranks this short, would consider everything that has 144bcd with required length, 130bcd would also do. Please help.

Spa can do you some 160mm ones, for square taper BBs e.g. https://www.spacycles.co.uk/m2b0s109p45/STRONGLIGHT-Impact-Double and 130-155mm https://www.spacycles.co.uk/m2b0s109p1927/STRONGLIGHT-Impact-Kid

Hello,
I really appreciate you taking your time to share this with me. Unfortunately these don't look like 144bcd. Nothing is written in the page as well.
I would really love to buy cranks that use something else but a square tapper bb (unless they are used cheap ones). I wasn't really specific about that, sorry.
Kind regards,
Jone

Rotor go down to 150mm.

Ah OK - I think Spa or SJS might be the best suppliers, they're specialists in touring cycles and such. It may be worth giving Spa a ring or popping them an email. They're very well regarded among audaxers etc. Good luck with finding your crank lengths.

Thank you!

Easy option might be pedals with a higher stack height and shoe inserts? Obviously not ideal to move your feet miles away but you might get an extra 10mm, sort of turning a 165mm crank into a 155mm. Might be cheaper and there's a much wider selection of cranks

Morning,
the kids track bikes I used to look after at Meadowbank Velodrome had 155mm cranks on the small ones made by Miche and they still do the Miche "Young" range of chain sets

Paul Milne Cycles is advertising short crank chain sets by PMC Lasco, Alloy Short Kids Crankset Cranks 155mm 165mm 145mm on Ebay but they are 110 BCD .

I don't think you will get 144 BCD cranks shorter than 160mm as a regular items.
An option would be to cut down a suitable set of cranks and drill and tap the pedal spindle holes at the length you need. Some crank sets like the one in the image look quite suitable for that modification.

Good luck, the correct fit on a track bike is every thing ...

Why not buy a Rotor track spider/axle and some Aldhu arms which go as short as 155mm?

Because I don't have spare 300 pounds for them. If anyone had a pair of used crankarms I would gladly take them. :)

Thank you for all of the information. The third option you were talking about is what I am planning to do unless somebody decides to sell their 150-155 mm rotors here or on eBay. I think 160mm won't solve the problem since by many calculating options I score 153mm recommended crankarm lenght so I am left with either the rarest of options or drilling a hole. Apparently when I ride I am reaching the lower crankarm hence the extreme toe down and my other leg is bent so much it makes a very unhealthy angle. I am rocking on a saddle like crazy. This is why the following noted by @clipon wouldn't work but even make things worse .

Not perfect, probably make them work though

Thank you. It won't work since they're neither 144bcd nor 130bcd.

why are you stuck to 144/130? just change the ring?

Just fyi I've got rotors 150mm (£300) on my main bike, PMC 145mm square taper (£40) on my winter bike and also some strong light 145mm (£20) on a third bike, Al are excellent

I want to have good options for 1/8 rings. For 130 I would buy Stronglight Zicral and that would be decent. what do you suggest?
