Before cutting anything I would do some power measurements if I were you.
When I was at uni I managed to blag some time in a wind tunnel. I could get my back very flat which lowered the drag but it also dropped the power quite a bit mainly because it was difficult to keep my arse on the saddle, all the weight was going through my arms. By lifting the front end it put more weight onto the saddle which felt more solid and I could output more watts which overcame the increase in drag. Also because my back wasn’t as flat I found that angling the tri-bars up so my hands were level with my chin helped reduce drag and was better for me at realistic speeds (flat arms was better at 40mph+), all years before Floyd Llandis started doing it!
Non of it helped me crack 20mins for a 10 even on V718 when the container ships were unloading though!
