SRAM 2019?

[jih]

I love SRAM shifting and I'm excited with the idea of a 10-28 with an 50-34.

50x10 is the same as 55x11, or like 53x11, but half a gear higher (4.1% more). Too tall for me to have on my bike for all but the steepest of descents, but if you can use this combo it's good that the option will be there.

If you jump to Rotor 1*13, you still need Rotors new Revolver hub.

And have a loooooot of faith.....it's a disaster.

How do you know 1*13 is a disaster?
Or do you feel that way due to the need for Rotors rear hub?

It's not my feel, I know it.

Please refrain yourself from acting like an oracle. Just quote one or more reputable sources and you'll sound a lot more reasonable.
I'm not saying you are wrong. In fact i agree that rotor's current implementation of 2x11 are not up to par. So it's natural to guess the 1x13 to be bad as well.

I haven't seen a rim brake version, is the new etap disc only? And any rumors on force etap?

That’s actually a great question. My guess is SRAM isn’t quite ready to ditch the high-end rim-brake market completely. Also both Katusha and Trek-Segafredo’s TT bikes aren’t available with discs yet.

We have long 1%-2% downhill gradients that sometimes get a tailwind, so 50x10 could be of use, so it's not really about steepness at all, it's about max speed. Very rarely I get spun out. The amount of time I lose is insignificant, but it would just be fun to pedal up to those higher speeds. Certainly this would be the max gearing I'd like on an aero bike.

Or perhaps run 48/32 and 10x28 on the climbing bike. Just hoping there aren't any hub standardization changes. If it's 12 speeed with reduced jumps a 50x34 and 10x32 might be a nice choice too.

Have to wait for the details.

[TobinHatesYou]

I would personally be very interested in 46/30x10-28t for steep climbs, perhaps 10-30t

10-11-12-13-14-15-16-18-20-22-25-28
10-11-12-13-14-15-17-19-21-24-27-30

48/32 would be fine as well.

If moaners ran tech companies we'd all be riding around in 7 speed come 2019

I don't see why some guys complain of Sram going 2*12 speed?
How are they supposed to solve the angle of the spokes between hub and rim?

Thanks for summing up my "moaning". I have no problem with 2*12. It will be great for a lot of people. But unless there is some crazy tech involved we don't know about, for me it doesn't help me acheive anything a 2x11 or 2x10 groupset can't.

On one hand it's "how can somebody possibly get to a 1x14", then in the next sentence talk about how someone is already doing a 1x13. I was hoping that SRAM was in a long release cycle because they were going to 1up rotor's 1x13, not match Campy's 2x12. It's not that crazy of a concept, technology typically improves at an exponential rate not linear. But only Rotor has made a non-linear jump in the gruppo game lately...kudos to them even if it's not perfect out the door.

I’m hoping they introduce a 10-34 or 10-36 XD(R) 11s cassette.

Plenty of big climbs around here, but the paved stuff is relatively tame, gradient-wise. My new disc road bike is going to be 46 (oval) x 10-42 until a smaller spread cassette comes out.

FWIW, I’ve now run 2x9, 2x10, 1x10, 1x11 and now 1x11 “road” on the same hub across five MTB, CX and road bikes.

It would be nice but that will all be locked into 12s I'd say.

Will the 12s freehub work on an existing 11s disc hub? As in would my 240 based disc hub just require a freehub swap and slot back into my existing frame?

Do we think we will see a 12s rim brake setup?

Can’t see why it wouldn’t be. I’ve run 9s/10s road, 11 speed road, Campy 11s, and XD freehub day on the same disc brake 240. My understanding is that XDR is just a modified XD. Should be a simple swap. Just like the new Shimano-standard 12s MTB freehub for DT Swiss hubs.

Hell, I’ve also run it 5x135, 10x135, 12x142 and have an adapter to make it 12x148 with the adapter and a 15min re-dishing.

DT Swiss is probably the largest OEM supplier of hubs to high-end bikes in the world. There’s a reason both SRAM and Shimano both made sure they were one of, if not the first big hub/wheel maker board when their new standards came out (XD, Micro Spline).

It should...it's the exact same width as 11spd HyperGlide and MicroSpline. Heck, you can use 11spd XD MTB cassettes on XDR...just need to add the 1.85mm spacer.

As for rim-brake next-gen eTap, I'd guess that's a pretty safe bet. Going hydro only would alienate people with fancy travel bikes using mech discs. A lot of TT bikes are still rim-brake only as well, so there will probably be road hydro, road mechanical, TT hydro, TT mechanical, and maybe even 1x SKUs of each.

One of the bikes of World Champion cyclo-cross Wout Van aert is equipped with the new red etap 12v....

Got a bit excited when I read this. Didn't initially realise how big a difference the 10 would make, but yes, seems you're right.

SRAM 12 speed isn't just a nice incremental upgrade, it's a weaponised version of 11 speed

Lewn posted afterwards talking about gradual 1 and 2% gradients with tailwinds behind him. We have those here and the KOMs are mad competitive and you can just about hit 50 with a bit of tucking and spinning, tucking and spinning. However, looking at the cadence chart it seems that on 50x10 you can spin 130 cadence over 50mph!

Absolutely brilliant

[alcatraz]

I think it's a mistake to move the chainrings closer together in size.

Sure you'll get nicer shifts but you also reduce the use of the small ring and front derailleur alltogether. There is too much overlap in the gear ratios.

Are they trying to move us towards 1x for road?

[thePrince]

Of course...there is already huge overlap in gear ratios. A standard 53x39 on a 2x11 has 7 or 8 redundant options depending on cassette. Why do you want that?
