Maelochs , by too little of the bar, do you mean, simply always staying in one hand position?
I often transition between hoods and drops, hopds when pushing at a more neutral effort, and slip into the drops when tackling some tricky stuff where I'm more likely to require the brakes.
I bought two 700x28 tires at my local bike shop and changed just the rear tire so far.
As for drop bar angle, I read online that the tops being parallel with the ground usually isn't the correct position? That you want the bars to angle downwards slightly? I currently have the angled a bit higher up than you see in the latest photo, not sure if I'd want to go any higher.
I am now looking for a 46cm drop bar and a compact crankset for this bike.
