Nice gotta be good for CX when those brifters meet disks. But when will production begin.
electric sram coming soon.Nice timing. Yesterday was Shimano's announcement of 11speed ultegra di2 with hydro discs. That's going to be the group I put on my next bike. That's going to be the group that is going to rule CX.
I cannot wait for a size comparison. The problem is that brifters just don't have enough space inside for mechanical shifting and hydraulic fluid reservoirs, that's why the Sram things are huge.
As for the R785 system, the complete system including shifters, brakes, hoses, mineral oil, and two RT-99 rotors works out to be 1066g. Compared to 6870 shifters with rim brakes, the hydraulic system adds less than a pound – somewhere around 340g.
I saw this today but I'm confused - I thought you had to have a special fork for disc brakes? But it reads like they're just selling it as a kit for any old bike.
Funny I seem to recall a discussion on this board that came to the conclusion that disc brakes for road bikes was a bad idea and would most likely not happen anytime soon.....?
Are these new brakes going to be used in UCI races?
I can certainly see them in CX events, but how about TDF?
Well good news from that BikeRumour article is that come November, I should be able to buy a 11 speed rear derailleur + 11-cog and then upgrade my U6770 to 11 speed Di very quickly.
Depends how much climbing you are doing. How much climbing are you doing?
I don't believe that for a moment. The "trim" function only works when shifting between 5th and 6th on the back - I thought when I bought the U6770 that the trim would be gradual across each rear gear change, but having put the whole bike on the e-tube and watched the process carefully, the FD just trims once (and its enough to avoid contact on all gears). There's not even any electical adjustment you can do to the FD (even the mechanical adjustment I find quite suspect, if you remember from my bike build). The gate on the FD is way too wide to need to change it to - frankly they should have a fully moving trim and thinner gate for more precise front shiftingYou`ll need a new FD as well, as the trim function won`t be set up for the correct widths
