Subject says it all here. Struggling to decide on a drivetrain for my new TriRig Omni. Price is essentially a wash.
I haven’t really seen many reviews of the 9150 groupset yet. The eTap is great IMO because it makes transportation so easy. Just unbolt the der’s and package them up, no worries about bent hangers in transit.

Does anyone buy (or even sell) a wired computer or power meter anymore? Nope!
Two years from now a wired electric group will be a thing of the past.
I put eTap on my Shiv TT. I liked the fact that charging the batteries is really easy. Just a much more simple system.

I disagree…I love my wireless computers and power meters, but there are still issues with signal transmission. Sensors (power meters included) temporarily drop not infrequently. There’s also a road near my house where my HRM always reads in the 180s for a half block stretch because of some sort of weird interference. I can deal with brief erratic heart rate readings or stretches of zero cadence or power…gaps in information won’t hurt me as long as they are brief. However, if I’m going uphill and needing to downshift it’s gotta happen with 100% reliability. Wires are really good at that, wireless is still a work in progress.
Hands down, SRAM.
A.) It’s wireless, and instlation is easier.
B.) The batteries are interchanagable, so you should always be able to shift in the rear if one battery runs out.
C.) Blips allow you to put the shifters where you want. “Limitless remote shifting positions for drop and aero bars”
D.) I am SRAM fanboy, and you can be too!

Right now, price point prevents me from running SRAM or Shimano. However, I did fork out $259.00 for Xshifter, so that will be my first taste of wireless shifting. Discussed on Slowtwitch here:

FSA also has wireless electronic shifting, K-FORCE WE. The movement of the rear derailleur is more like that of a robotic arm than a traditional derailleur with a parallelogram.

I’ve had trouble deciding on the same thing. A while back, I asked the same question here. http://forum.slowtwitch.com/forum/Slowtwitch_Forums_C1/Triathlon_Forum_F1/Shimano_Di2_vs_Sram_eTap_P6006260/?search_string=di2%20vs%20etap#p6006260
Can you run a 1x eTap setup?
I would think you could, as you wouldn’t need to pair the front derailleur and that would allow you to shift normally with just the rear. I don’t think, however, that the rear derailleur can fit the 31/32 cog on the 1x11 cassette.

They have announced a wifli version of their RD to accommodate 32t. I don’t recall the release date, but I think it was December.
The new WiFli version can. The only reason not to run 1x is the lack of a clutch in the RD. Some people feel comfortable just using an X-Sync chainring and no clutch RD, some don’t. Depends on road conditions.
I personally haven’t tried 1x on the road, but 1x on my mountain bike has been pretty faultless.
You can always buy a RoadLink to accommodate the larger cassette. That will allow you to clear a 32t, and maybe 36t? while using a standard, short cage rear derailluer.
Only suggested if you are going 1x up front.
I’m thinking the new Di2: the blip wireless box is a hassle to hide vs an internal battery; di2 = faster shifting; the new di2 TT shifters look great as do the new TT pursuit bar shift/brake combo; while Di2 can be run as a 1x, if you were to throw in a double front chainring, say for terrain with 80-100ft gain per mile, the di2 auto front shifting would be ideal for TT.
I really like the sram etap, and I like the idea of pairing x-shift with a 1x system as it would be lighter than both etap or di2 and has the electronic shifter which provides the ease of shifting that makes electronic great for TT - you shift more often. I know with my current RTR sram shifter, I shift less often than if it were electronic because it does take a bit more effort and the RD (sram force) is not as crisp or forceful as my di2 DA RD (which does wear down pulleys quicker) on my road bike. The weaker shifting of the Force RD forces me to let up on the torque to make the shift. So, going back to di2 vs etap, I’d go with the RD that allows for the least ‘pedaling torque let-up’. And, if X-shift accomplishes that as well or better than either di2 or etap, I’d consider it.
Also, really looking forward to your impressions of the Omni. I kind of wish Nick would lower the stack and create an aerobars that uses the ‘seatpost’ design Enve used on the P5x for aero bar adjustment, and basically use a monorail saddle clamp to attach the post to the Trek SC style mono aerobar so that it can easily handle fore/aft and tilt adjustments, and hide the lower portion of the post with an extended magnetic nosecone, showing this design is possible without disc brakes.
the di2 auto front shifting would be ideal for TT
This is the exact reason why I chose eTap over Di2 9150.
you can run di2 9150 as 1x, so you have more powerful shifting and more options with di2 (1x or synchronized/auto front shifting). what’s your logic?
I do not want nor need my front derailleur auto shifting during a race.
I see, it is true that Di2 requires the auto front shifting with their TT shifters… if you use 2x front shifting.
I made the statement before that the ease of shifting with electronic encourages more shifts; I’d say the same applies to the auto front shift. I would be in the best gear more of the time with it vs than without it, so Di2 for the win for me

online reviews interpretation F@#$%@ experts…
I’m thinking the new Di2: the blip wireless box is a hassle to hide vs an internal battery; .
I’m interested in seeing more solutions to where to hide the blip box. I saw a few posts about positioning the blip box when etap first came out but I curious how people are doing it now (same as before or perhaps different). One of my teammates has etap and I agree, it seems like a hassle compared to the bikes on our team with di2.
I’ll stick with my mech groupo for now
eTap - the weakness of Shimano is in the cables. eTap removes this and I’ve seen no horror stories of connection getting lost.
