eTap for MTB

[Cat3roadracer]

Anyone know the timeframe for this?

Thanks.

My touring frame is waiting for an Etap 2x11 kit. 42/28 chainrings and 11 to 42 cogs. It wants one.

For my application I'm thinking 1x11, only one shifter, one der.

How difficult can this be?

Does SRAM even make a mechanical 2x11 MTB group?

Since Etap is all about one shift lever per side, that's probably a bit off. You should get Di2.

no actual idea whatsoever but my guess is that you're going to be waiting at least a couple years. we haven't even seen Force level eTap, and that's super easy for them; basically just making the same as the Red one with cheaper parts. so before we see that, I doubt you're going to see a MTB version. I'll bet they're working on it though.

sram was 'in the corner' with road and then etap..with the one shift lever blade per lever for all functions(dbl-tap) but no such constraints with MTB, as they have had 'trigger' MTB shifters for a while...I imagine patents will be an issue VS shimano tho..I'm thinking a smart system, 2by, with a no LH shifter, front der that is programmed to shift when the chain gets in certain places on the rear...oh wait, that's shimano MTB Di2..

I'm speculating here but since SRAM has killed off the front derailleur for their MTB groups I don't think you'll see a 2x option, likely just shifter and rear derailleur that will work with existing 1x12 eagle stuff.

I'm also going to speculate that the e-mtb shifter would come before e-force. I can't see sram wanting to give shimano any more ground in the e-mtb shifter niche than they need to.

Yes, several different levels. The top end is called XX, which is the rear derailleur I currently have on my touring IF. I don't currently have an XX crankset because I haven't found one for the right price used. I have an XX front derailleur waiting until I do.

cable routing on some suspension designs is convoluted enough. etap for mtb would be awesome

I guess you'll have to prove it to me. I don't see it on their website, but I could be missing them. I run XX crank and f/r derailleurs on my gravel bike and 11s at that, but the XX (ten gears per chainring) group was a 2x10 group. I don't believe SRAM makes a 2x11 MTB group.

I think this is right too. When SRAM went to 11 speed I think they also cut out the front derailleur entirely.

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.
