Shimano announces affordable road disc group

Shimano is aiming to bring road disc brakes to the masses with an updated nine-speed Sora R3000 group that features flat-mount mechanical disc brake calipers. Though pricing hasn’t been confirmed, this should be one of the most affordable road disc brake options, as Sora is positioned fifth, behind Tiagra, in Shimano’s group hierarchy.

Shimano’s trickle-down technology is featured in Sora’s disc brake calipers, which can be combined with steel or stainless steel rotors (available 2017). Also, the new mid-range RX31 disc wheelsets incorporates 12mm E-thru technology, borrowed from Shimano’s mountain bike components, offering a quick-release closure with a new SM-AX720 axle for easier adjustment, with a knob at the end of the axle.

Other features include cable routing under the bar tape for a cleaner look, lighter shifting, more powerful braking, a four-arm crankset, and black-gray gloss finish for Dura-Ace-like aesthetics.

The group is available with a four-arm double (50-34T) or triple (50-39-30T) crankset that can now be combined with wide-range 11-34T cassettes. This adds two extra teeth over the previous Sora cassette, making for easier climbing without sacrificing the 11-tooth cog for high-speed pedaling.

Sora R3000 components are set to be available on complete bikes and in the aftermarket this summer.
