Ein neuer "unnötiger" Standard, der die Kompatibilität von Gabeln und Bremsen einschränkt. Aber das ist ja wohl der Trend der Zeit.

NEW SHIMANO 105 GRADE HYDRAULIC ROAD DISC BRAKES BRING SUPERIOR STOPPING
PERFORMANCE
Shimano is today giving road cycling consumers even more advantages over the pro’s with a new
milestone in braking technology. The introduction of Shimano’s new 105 grade hydraulic disc brake,
combined with a flat mount caliper, brings high performance stopping power to the sportive rider,
making for a safer and superior road cycling experience.
Using technology developed and refined in the first generations of
hydraulic road disc brakes, the 105 grade hydraulic disc brake (STRS505)
lives up to the 105 groupset ethos of ‘trusted reliable
performance with advanced functionality, smoothness and
ergonomics.’
Shimano’s new 105 grade hydraulic road brakes use a mineral oil
reservoir housed in a compact and ergonomic mechanical lever with
a 10mm reach adjustment to suit larger or smaller hand sizes.
Gear changing is handled with light and minimal finger movements of the two levers, resulting in a
positive, clearly defined click and precise gear engagement.
Hydraulic hosing carrying the mineral oil features the improved cable routing introduced on the ULTEGRA
hydraulic system last year, with the hose running down the inside of the caliper for a neater and more
aerodynamic design. Set up of the hydraulic system is simplified with Shimano’s easy-to-install pre-bled
J-KIT (Junction kit) system and a funnel bleeding option.
The new Flat Mount front fork and rear stay fitting (BR-RS805 and
BR-RS505) also brings aerodynamic advantages by introducing a
closer fit between the caliper and the frame, reducing the need
for visible mounting bolts. This new design allows consumers to
move away from the mountain bike history and look, which has
been used until now, using a method better suited to high
performance road bike riding.
Together with the lever and caliper the new SM-RT81-SS 140mm rotors and pads allow for consistent
braking performance through all weather conditions with innovative ICE heat management technology
and adjustable stopping power that can be tuned to the riding conditions, terrain, rider’s size and ability.
The cooling ICE technology found on the SM-RT81-SS rotor comprises a three-layer sandwich structure of
stainless steel and aluminum to allow heat to dissipate rapidly from the surface of the disc rotor, reducing
the risk of rotors becoming hot-to-touch after extended braking whilst descending.

After introducing hydraulic disc brakes for road usage in 2013, then making it available for mechanical
shifting in 2014, today’s Shimano 105 grade hydraulic disc brake (BR-RS505 and ST-RS505) is fully
compatible with Shimano’s mechanical 11-speed DURA-ACE, ULTEGRA groupsets, and of course its 11-
speed 105 groupset.
AVAILABILITY IN THE MARKET:
- Shimano 105 grade mechanical shifting system, ST-RS505 : Oct 2015
- Flat mount spec brake caliper, Shimano ULTEGRA grade, BR-RS805 : July 2015
- Flat mount spec brake caliper, Shimano 105 grade, BR-RS505 : Oct 2015

Nä. Wurd schon mal angekündigt.
Ansonsten, was den neuen "Standard" betrifft: Mal schauen was sich durchsetzt. Shimano kann ich mir eigentlich nicht vorstellen. Die Unterschiede zu Postmount sind imo zu gering.
