What about a P2M for your Specialized cranks? Conflicting numbers out there, but they might be 137.5mm q (or might be 147.5mm)

They're the smaller (137.5mm).

So, they're lower Q than my DA but not as low as Hollowgram SI /SISL2 cranks.

The other issue is they are too long for my TT bike - I need 165mm to prevent my hip nerve/blood vessel crushing causing my left leg to go numb.
