Previously, the longest cage available could only handle a 32t sprocket. There are two rear mechs available, including the optional long cage version which can accommodate an 11-34t cassette. It receives Shimano's mountain bike Shadow technology that pulls it up underneath the cassette and chainstay and out of harms way. The rear mech on the new 105 is also light years ahead of the older version. It has a compact toggle designed, better tyre clearance and an integrated cable tension port removing the need for an in-cable barrel adjusted.

That means a down-sizing of the whole hood, making it far less bulky in the hand to the previous 105 and the addition of a chamfered top, which should make it easy to hold in the rain or with sweaty hands.Īgain, the new R7000 front derailleur receives the same good looks as Ultegra R8000. Moving up to the controls, the new Shimano 105 R7000 hoods and levers get the same ergonomic do-over that Ultegra R8000 received.
