Having already unveiled the new Tiagra groupset, Shimano have come up with some more trickle-down news, with the announcement that hydraulic disc brakes will soon be available with the 105-level groupset. 

Shimano say the new system will follow the 105 group ethos of ‘trusted reliable performance with advanced functionality, smoothness and ergonomics’. What that means in practice is they are essentially a more affordable version of the Ultegra mechanical-hydraulic shifters that were brought to market after the popularity of the Di2 versions.

It will used the improved cable routing from the Ultegra system, where the hose runs down the inside of the caliper, making things neater and more aerodynamic.

It also uses new fork and rear stay fittings to put the mechanisms closer to the frame, giving it a different look to mountain bike-style discs and also allegedly improving aerodynamic performance.

Speaking of braking specifics, the ICE technology is another feature of the 140mm rotors. ICE is a heat management system that reduces heat build-up over long periods of braking – descents, for instance – and adjustable stopping power that riders can tune according to terrain or conditions.

However, if you’re desperate to get your hands on the 105 hydraulic system you’ll have to wait for a while, as Shimano say availability will be October this year.
