My first SSFG build

Thanks, glad you like it!

I want to try a change with the cockpit of this bike. Want to make the riding position less aggressive.

Define less aggressive.

Does it feel a little stretched? too much weight on handlebar? etc.

Yes, it feels a bit stretched which I guess is the result of the bike + stem combined length together with the saddle vs bars height differential.

The result of that is more weight on the handle bars. The non oversized bars with the thin bar tape does not help either.

I am 190cm tall and 110kgs heavy !

BTW I raised the stem and changed the drop bars angle and it already feels more comfortable.

I also find old bars a bit skinny for my manly grasp.

I've tried Cinelli gel pads, but without much success; they're difficult to wrap nicely and difficult to position effectively.

An old inner tube does make an appreciable difference to the grip size, but less so if vibration is a problem.

Talc on the inside of the tube will make them easier to slip on and two sections allowing a gap for the lever clamps is easier than trying to get the clamps over one continuous piece.

Choosing the right size tube helps to get a snug fit, which will prevent them from slipping.

Of course your existing tape may not now be long enough, but it sounds like you could do with something thicker anyway: a shame as I think it looks really good.

Sound like the reach is a little on the long side rather than the bar being too low, a shorter stem will help.

True, but raising the bars does reduce the reach.

It does, but only very slightly.

Yes, you're absolutely right.

If you get another stem, keep it black, I think the black stem and saddle works really well, balances the forks and chrome seat stays nicely, lovely build.

Glad you like it !
Saddle now is a black Brooks swallow which in my opinion looks as nice!
