Hydro disc brakes and cold weather
When I think hydro I think oil. When I think oil and cold I think sludge. Does anyone have any experience with cold rides (-5 to 5 F, -20 to -15 C) and hydro brakes? I'm wondering if they get sticky or have other difficulties or if its just fine.
I'm contemplating a bike purchase and one option is mechanical disc brakes, the other hydraulic.

My olde Hayes with DOT brake fluid felt the same as in the summer... at least as much as I could tell with thick gloves on. The avids with mineral oil seemed a bit more vague-feeling, but that could have been in my head. Lots of stopping power. I haven't had the XTs (also mineral oil) out below freezing yet.

My Avid juicy's with DOT fluid work fine all winter long. it rarely gets below 10 degrees f here though. i haven't had a problem with mechanicals either though.

No problem. I have ridden -20 C and the brakes work wonderfully. They do tend to squeak more in the cold weather.

I used to believe that hydraulics would be a bad idea in cold weather. I've been informed since then that both mineral oil and DOT fluid experience very little viscosity change in wintry conditions. DOT might be a little bit better, but the hydros may actually be more reliable than cables, which are prone to sticking and freezing.
