More detail and information on model variations for available lengths can be found below.
The range is from 160, 165, 170, 172.5, 175. Not all models go down to 160, some start at 165 and some older models do go up to 180. Some models also have ‘in between lengths’ of 167.5 and 177.5. I won’t get into too much specifics as there are quite a few models available and there is still some availability of older generations cranks.

Need something for rehab after an accident or for various medical reasons? There are crank shorteners that can be fitted to your cranks and potentially be used temporarily, depending on the circumstances. I chose not to include the link as this is more of a medical consideration and should be done with the help of a professional. I just want to mention this here so you know that when/if needed, when there is a will there is a way!
