Rear derailleur here

This seems rather cheap. The 8050 series is cheaper than the 6870 series at Pushys.

The front derailleur is $183.99, rear derailleur is $219.99, after the discount. You have to make two separate purchases if you want to buy both, as the discount is off the whole cart.

The new RD lets you use an 11-30 cassette, the 6870 only allows 11-28.

8050 parts are backwards compatible with 6870, if you just need to replace a component.

The sale ends at 11pm AEST today!

FD:
$290.98 at Wiggle
$301.49 at CRC

RD:
$347.49 at Wiggle
$350.99 at CRC

    After purchasing a kmart bike I'm suddenly interested in weight reductions. How many grams are they?

      Well at least you won't need to add extra weights to your bike to pass the UCI 6.8kg limit.

    Front - 132g
    Rear - 242g

  Nice, might upgrade my TT bike.

  Pushys is great.
  Usually fast dispatch.
  Just bought a R8000 rear derailleur and R9100 front derailleur from them.

    I love Pushys - it's usually same-day delivery for me if I order the night before or early in the morning. And that's on the free shipping tier!

  What else do you need if you go from non di2 to a di2 setup? Assuming existing cassette is compatible.

  Have a road bike with ultegra and a mtb with deore and am wondering what a di2 upgrade would cost.

    You need new shifters, front and rear mech, 2 x junction boxes, a battery and wires. Usually about $1600 new or you can find second hand for maybe 600-800 depending if cranks are included. As Ultegra 8000 has just been released, stock seems thin on both new and old gen, I couldn't find any on Wiggle or Pushy's and Dura ace is about double the cost of Ultegra.
    I went the second hand option when upgrading and don't regret it! If you get crafty with firmware, you can mix and match 6770 and 6870 parts to get 11 speed while only upgrading the rear derailleur. Shimano unfortunately broke compatibility with a firmware update but thankfully you can reverse it if you have access to a PC link.

    Get onto the Facebook Swap/sale groups, there are normally people on there offloading spare Di2 bits like cables, shifters etc. As somebody that has done this upgrade before, you n4eed to know the different cable lengths for your frame. Shimano makes the etube cables in a range of lengths, you will need to get the right lengths for your setup. You might also need a plastic insert for the inside of your seat tube to hold the battery!

      If ever in doubt with cable length (apart from your shifters), get the longer one… there's nothing worse than getting your bike apart then finding out a cable is short by a centimeter!

      Don't forget to wrap any loose bits in your frame with some foam or something. Otherwise you'll hear them rattling about on bumpy roads.

      You might also need a plastic insert for the inside of your seat tube to hold the battery!

      Yup, or you can use some foam to wedge it in too. You can make a loop with cable ties to allow you to fish it out in the future.

    Last year I upgraded my bike from Ultegra 6800 to Ultegra Di2 6870 for about $800 with used derailleurs and new shifters/battery/cables/junction boxes. I sold the old derailleurs and shifters and got some money back too .. I can't remember how much.

  If you want to save weight, eliminate the front shifter, derailleur and second chainring. Save a tonne!

  Now that road bikes have so many gears on the rear cassette, the front shifter is redundant.

  But shops and Shimano will not tell you this, because … $300 FDs are lucrative.

    Sure, until you have to do that long steep climb. :)

      OK, I left out the part about changing the cassette to suit.
      A 1x12 now has as many effective gears as a 2x9 from not long ago.

      But for a "long steep climb", I may take the touring bike with the triple chainring :-)

      Even MTBs are doing it, with SRAM selling a 10-42T 12x1-speed.

    My race bike is nearly 1kg under the uci limit so losing gears….
