Just last week, SRAM unveiled their updated Apex group, giving their entry level road series disc brakes and expanded gearing options. Now, Shimano’s equivalent, Sora, gets freshened up in its own way.
The aesthetics of the higher end groups trickle down to the new four-arm, asymmetrical spider on the cranks, the derailleurs are more shapely, and the levers switch to internal routing, letting you hide the cables under the bar tape. They’ve even got new a flat-mount disc brake caliper joining the rim option, with both drop and flat bar levers to actuate it. Pedal past the break for all the details…
The Sora R3000 group will be offered with double (FC-R3000, 50-34) and triple (FC-R3030 – 50/39/30) chainring options. There’s also a more traditional 5-arm crankset in 2x and 3x with included chain guard for commuter bikes. The cassettes will have a new 11-34 option, up from the prior 11-32, for a bit easier pedaling.
Those commuter bikes will likely get the RapidFire Plus trigger shifter option. For drop bar bikes, the new STI levers keep everything inside, no more wires jutting out the sides.
The derailleurs end up looking very much like 105, with the front getting the new, taller actuating arm that dramatically decreases effort at the lever to perform front shifts.
Flat bar builds will have a simple lever to saddle up with the triggers. Rim brake calipers are all new, featuring a dual pivot design they say increases braking power by 20%. They also get a quick release cable lever to make wheel changes easier. As more and more bikes switch to disc brakes, the new Sora flat-mount mechanical brake caliper will help keep everything on the same page.
They’ll combine with either steel or stainless steel rotors in 140mm and 160mm sizes.
Those rotors will fit with the new mid-range RX31 disc wheelset, which gets 12mm E-Thru axles…
…and a new axle design (SM-AX720) that makes adjustments easier. Weights, pricing and other tech details aren’t announced yet, but look for the parts to be on bikes and available aftermarket in summer 2016.
