After some discussion on here about crank length - I've measured up and it seems I should be using 165mm crank length.

I've seen some new ones that I'm hovering over but if anyone has a set they want to sell, please let me know.

Cheers Mac.

This is totally no point to you... But... I have some Boost 170mm SLX. 30 chainring AFAIR which hardly looks used.

If its any good then let me know and we can work out a price with all proceeds going to the Yemen hunger crisis (specifically for the orphans but poor people IME are always the most generous and thus feeding an orphan would mean those around them would be fed too)...

Pretty sure 170 would be spot on for you
