Don’t take these comments the wrong way, it’s not my intention.
The angle you’ve got your Brooks is going to make you keep sliding to the front and you’re going to be constantly pushing yourself back up. It’s not comfortable riding like that. You should level it out or, if it’s gone a bit more hammock-like, slightly nose up. You’ll then be able to lower the seatpost a little.
That’s
one reason you need your bars at that angle. But you shouldn’t need your bars at an angle like that. You’re obviously fairly tall. See if you can find some wider bars which are flatter across the top and with a more conventional bend. There are older bars in this shape, but you’re more likely to find non-anodised bars from the 1980s in the shape I mean and they won’t look out of place on this bike. The squarer bends at the tops of the bars will give you more hand space across the tops and let you put that type of brake lever nearer the tops of the bends without them sticking out or being too high up.
Finally, I think you probably need a longer stem. The one on there looks quite short and I think you’re taller than that reach. Look for an 80mm stem to start with and maybe consider 100mm (but older stems can be hard to find that long).
I think once you’ve done those things you won’t need the bars at such an extreme angle. Slightly off-horizontal, but not how you’ve got them. Once you’re sitting
on the saddle and not pushing yourself
back onto it, you should be able to level the bars out somewhat. Then the bike will be a lot more comfortable to ride
Example attached is my daily. That’s more how it should look if you have a bit of saddle to bar drop. It looks a bit extreme because of the angle of that picture but I’ve done over 35,000 miles on this bike.
