SRAM eTap Actual Weights

About a week ago, we finally got all of our SRAM eTap groupsets in the shop.  We got six full groups out of the first batch of twelve to hit the US.  They come with the wireless components (derailleurs and shifters), a Quarq power meter crank, and SRAM Red brakes, cassette, and chain.  Out of the groupsets, two were TT eTap groups, which have the wireless ‘blips’ that actuate the derailleur like the paddle on the shifter.  I will be posting a good installation article that goes more in depth than the initial article I wrote on eTap.  In the mean time, I thought it would be cool to have some photos of the components and their actual weight.  Pretty light stuff and I really think it will be a popular option.

265 grams (Shifters), 160 grams (Front Derailleur), 238 grams (Rear Derailleur) = 663 grams.

So, after seeing the weights, I obviously wanted to see what the comparison was with Shimano Dura-Ace Di2 9070.  Here it is

230 grams (Shifters), 107 grams (Front Derailleur), 214 grams (Rear Derailleur), 50 grams (Battery) = 601 grams.  I am pretty sure that while the wires do weigh something, it’s not hardly enough to make it heavier than the eTap (maybe if you use 1000mm wires for all of the bike, haha).  So, while eTap is slightly heavier, it is not by much.  If you look at cassette, brakes, and cranksets (not a Quarq), chain, and bottom bracket, it is still lighter than Dura-Ace by almost a hundred grams.  This savings is almost entirely in the crank and cassette weights.  Anyways, hope this shed s a bit more light on the newest groupset.  I am also anxiously awaiting more photo leaks of the new Dura-Ace 9100, which looks to be wired, but will have an A Junction that can be updated and adjusted wirelessly.  That is a way more efficient way of easily checking firmware and diagnosing issues.
