eTap for MTB

Of course, as you've pointed out, some (all?) 10s SRAM MTB stuff is compatible with 11s SRAM road shifters, which is awesome.

Kinda a shame sram is making your gearing choices for you, ala 11s and MTB. Not really into MTBing but pretty sure there is a market for 2by and even 3by where people ride these things, imho of course. Doubt shimano will dump front ders anytime soon on their MTB 11s rigs.

Maybe not "dump" but if you are talking about people who ride and buy new equipment above the Tiagra level front ders are almost a dead issue. 3x is basically non-existent. If you are talking about cheap OEM level stuff, fds are still in play. 1x took over MTBs a while ago and for good reason.

As an illustration, when you sort for 2x on complete bikes on Competitive Cyclist, you get one page of results. https://www.competitivecyclist.com/m...%3A2%5C+x&nf=1

whereas selecting for 1x gives you five. 3x does not exist.

You can say this is SRAM making decisions for the consumer but the market spoke a few years ago and I don't see any revolt in the MTB forums, Pinkbike etc..

Talking MTBs(Tiagra a road group), just saying shimano is offering 2by and 3by groups all the way thru XTR, in 2018...I think 1by, even with giganto rear cogsets, to 42t, still is a detriment to some in some areas, is all. But shimano is giganto also, so can make these things and sell where sram doesn't offer it.

I suspect the market for 2x11 (and 3x11 are you serious?) is so small that they've made a business calculation that they are fine with losing it completely. If a FD really fits a person's MTB needs then it would seem they could do just fine with 10 rear cogs if'n they wanted to use SRAM, but what do I know.

this. off-road riders and MTBer's especially love 1x11, and for good reason. go to a local MTB trailhead, try to count the number of FD's you see.

2x drivetrains are alive and well in the hardcore bikepacking community and some of those folks even run triples and BB7 cable disk brakes.

Oddballs.

yep!

As an avid MTB'r and racer, I'd say the main problem with etap for mtb is the battery position on the rear derailleur - it can easily be knocked off or even just rattled off. Then you'd have to find it....Plus, etap doesn't feel like it could cope with the strains of mtb riding, shifting under max strain and its way to slow. Plus plus- nobody even rides Di2 that I've seen, and I've been to many high level races this year and in the past.

Yeah, no one I ride MTB with has Di2 either, and while I'm no racer, lots of guys I ride with pimp out their bikes. With 1x shifting being so accurate, reliable and (at least with Sram) smooth, there's no real need for electronic shifting. It is a cool concept, though.

I thought this was worthy of resurrecting this thread:

I heard Schurter was running prototypes. Regardless of how one feels about the need for these things, SRAM is really outpacing Shimano in the mtb world right now.

Electronic derailleurs will have to come WAY down in price before I'd consider it for an MTB. I've only worn out a few road derailleurs in the past few decades, but I've gone through many MTB derailleurs. Here in New England, it's too easy to get sticks and branches caught in the spokes and/or drivetrain, resulting in the derailleur getting ripped off the frame (usually destroying the derailleur, and often taking the hanger with it). And if the derailleur does manage to remain intact for some time, the grit and grime around hear wears out the pivots much faster than road riding does.

In other words, rear derailleurs are nearly disposable items around here, so I'm not willing to pay a lot for them.
