SRAM hydro update
SRAM Road Hydraulic Brake Recall
For those looking forward to commuting on hydro disc brakes on their road bikes, looks like SRAM is sorting out the problems. I'll definitely not be riding outside the temperature parameters. Got to say they are really making a great effort at communicating.

The other thing is that video. I'm not sure if I find it refreshing or disturbing that they didn't put out something a little more polished. Maybe that lack of attention to detail is part of the problem?
It's just anecdotal I know but I was riding with a friend who had almost brand new SRAM Red shifters on his bike and one just plain broke when he tried to shift. There was no crash. A piece inside just snapped.

Yeah, they would definitely only be for your fair weather bike. In MN, that means above 0F, if I'm not mistaken.

If "above 0F" makes someone a fair-weather commuter, what am I? I've been waiting for 50F!
Do I need to go shopping for skirts?

FWIW, I do appreciate their candor about the problem. Knowing that the seals have issues with cold though is a problem. I imagine when new the improved design be fine even below -4, but once they've aged a bit?

I only use the front disc when I switch forks for the winter commuting season, so I've got all summer for SRAM to get its act together, and for Shimano to start selling its R785 lever/caliper combo separately (and without the shifter part, as it will go on a fixie). Looking forward to seeing how much better hydraulic is over mechanical.

TRP has some dual-action mechs that give you more of the advantages of hydros. I've read some good reviews on them,and would choose them over hydros for a drop bar.

Shimano just announced mechanical shifting hydraulic levers.

And that's why I said what I did. When they get things figured out,I'd totally rock hydros on a drop bar bike. But right now,I'll take the mechs.

Eventually I'll upgrade the calipers on my Soma Double Cross Disc to the TRP mechanicals (if I win the lottery).

the TRP Hydro with the master cylinder in the body of the lever seems to have been working , read of no recalls .
the shifter mech is displaced by the hydraulic mech. so shifting is done elsewhere.

Due to this we will be offering our crash replacement service on this new hydraulic shifting system. Not sure on pricing yet but might be as little as $50-$75 to get a complete rebuild for a front or rear units should it get run over by a herd of elephants.

They have a patent pending for the implementation of a stand alone master cylinder inside the brake lever body.
The M previous design was a closed system
the massively popular HS33, is Still in production.. I think the HS77 was a road hydraulic rim brake
just now, their reintroduced set , goes pure aero bar . for the TRI bike market I suppose ..

Errrrrm...how much experience do have with maintenance of decent hydros? I switched to hydraulics, in part, because mechanicals are so fussy and expensive to maintain.

Curious about this statement. I have 0 experience with hydros, so am pretty clueless, but I thought it was a pain in the butt if/when you overhauled them, especially when it comes to bleeding them. Perhaps this depends on the design/maker? BB7's do take a bit of care to keep adjusted in abrasive conditions, but I would not describe them as fussy or expensive; I replace the pads when they wear low ($15/set, roughly yearly), and occasionally adjust the pads so that they are close to the rotor. I spend perhaps 5 minutes per month on my daily commuter's brakes, and I ride year-round.

The pistons are probably not the issue since they are basically re-badged xt 785s but the lever action is far too all or nothing. I got very little engagement until I really pressed down on the levers. Moreover, for me the ergonomics of the r785s were terrible (especially from the hoods). Given that I have 6700 ultegra levers on my road bike and love the ergonomics this was particularly disappointing.

Mid-level or better Shimano are set up and forget for 5-10 years (depending on your paranoia about mineral oil stability). Moreover, since both pistons auto adjust there is, IME, very little problem with scraping/noise. My brakes basically never need adjustment and only rub/squeal when the pads are extremely low. I tend to agree that low end shimano hydraulics are not much better than mechanicals but once you get to SLX ($70-$80 online) or better there really is no comparison, IMO.
And anther thing: shimano/magura mineral oil is dirt cheap -- compressionless brake cables not so much.
