So the straps I will be putting on are these ones.
They will fit, asked specificly to the seller of it, just got to make them a bit wet to make em flexible enough for the holes to fit..
Also, the stem can drop a max. off 2 cm, but that should be fine.. The bar, agree on what has been said, noticed it rides ok, but not good enough yet.. So just a little bit of finetuning is required.
Riding fixed is something that I like to be honest, I'm not a speed maniac, especially not in the city cause it's just to damn crowded and you never know what you can expect. So the 1st few rides I took it really slowly and didn't feel any moment of danger for now. But you never know what the future may hold, so the brake is still an option, and I saw a nice method of working it away (placing the brake behind the stem), so maybe I will consider.
For now, I really would like to get the feeling right riding fixed, because it's something that needs a lot of practice but feels damn good.
I'll post an update when I fixed the few points on the ride to share my experience on the changes you gave me.
