Oneup 150-31.6 total length is 420mm (including actuator). According to my measurements it fits, but will only be on sale at the end of January.
Fox transfer got shorter this year. But it looks like it's too long anyway(
I need to measure everything again and look at the Fox instructions.
It's a pity that I can't buy OneUp now, a week ago I saw it on sale on US website, paid for it, but 150mm immediately ran out of stock and they made me a refund
