Bullhorn / TT hydraulic brake levers?

Where do i find hydraulic brake levers, bullhorn /TT style, suitable for Shimano 6870 (Di2)?
Aftermarket will do fine, as long as the brake fluid reservoir is OK for the brakes.

All tips greatly appreciated!

To my knowledge, there is no hydraulic brake option available for Shimano TT/Tri setups, either 6800/9000 or the newer 8000/9100 generation. Your only option would be something like the Magura RT6 TT, and glue/secure a set of Shimano remote shifters to the body, ala: http://fitwerx.com/adding-di2-shift-but ... ew-method/

Thanks, though i knew of 9180.

Question is if Magura requires Magura disc calipers to?

I think TRP has some that fit Di2 and etap shift buttons.

Learn something new every day. I didn't know this existed. Thanks!

I knew about these, but I don't think they've hit the market.

Edit: they're still not listed on the TRP website: https://www.trpcycling.com/shop/categor ... tt-levers/

Everything I've seen online is that Magura uses mineral oil, but there's a reddit thread that says they aren't compatible, so I would say you're going to have to use Magura calipers along with their levers.

I use standard disc brake calipers, that is part of Ultegra 6870 Di2.
But i also have a set of XTR calipers.
Both these work with 785 shifters. So i basically look for a brake lever that handles standard Shimano disc calipers.

My frame is postmount. That is why i ask for possible aftermarket versions.
I can always use R600 satellite shifter for the gears.

9180 seems to have only 1 button instead(aka syncro shifting only) of 2, at each lever.
This is actually the only gripe i have with these (and price)

And that they still don't actually exist yet, and reaching production on them seems quite low down on Shimano's list of priorities. Also, all the new series Dura-Ace and Ultegra TT shifters are designed as single button Synchro only, for some reason.
