Hi all, this is my first post,
what can I do to improve my position ? (this picture has been extract from a video)
Its actually not that bad but you definitly need some furniture.
Grant
I take the photo in the only corner where there is no furniture 
Anyone else ? I want to get lower and shorter but need another stem like 115 or 125deg and 80mm (mine is actually 73deg and 90mm).
Where did I can find stem like this and lighter than 150 grammes ?
I was in a local shop a couple of days and noticed he had a hook full of Salsa stems. They were all “high rise” stems with angles around 115+, short, and they’re cheap ($15 or so, intended for comfort bikes and similar). I haven’t tried it but they appear to be reversible. Weight? No idea but I’d be surprised if any short aluminum stem cost you more than 50 grams over another.
Is it uncomfortable to look up in this position? Lower may not be better if it is.
Relax the shoulders and sink into the position a bit.
