Yes meant to say XX1

I wonder if you could get these levers to work with Magura rim brakes of old, to use on a non disc CX bike?

There's a good chance the hydraulic leverage ratio will be wrong as M/Cs and calipers have become smaller over the years.

What frames besides trials frames have Magura hydraulic rim brake fixtures?

Freudian slip?

Would be interesting to see a 1x 11 offering for weight weenies. Are we not getting to the point where the FD is superfluous for many?


With a Wi-Fli RD and an 48 tooth Front and 11-32 cassette you effectively have 53-36 12-25 which should be more than enough for anyone.

However it would be neat to have a 10-36 Rear cassette which could effectively give you absolutely silly range - More like 12-30 on a 44 tooth Front.

Are XX1 indexing and SRAM 11sp indexing the same? Will a XX1 RD work with new SRAM 11sp?

There are lots of options for XX1 Rear Disc hubs.


I've done many miles... thousands... with a 48/38 and 11-32. Although you're not left wanting for climbs, it's not worth it over a standard or even compact crankset, at least for me. The cassette spacing makes keeping cadence in races or spirited group rides very challenging; one gear down and you're spinning like mad losing the wheel ahead of you, one gear up and you feel like you're in mashville. I also regularly run out of speed in 48x11 on some of the long descents around here.

I love the idea of 1x10 or 1x11, and I think that it's well-suited for cx and mtb, but it seems to me that well-rounded road riding necessitates a certain amount of subtle precision that you can only get with a 2xX spread.

I know guys who do "spirited group rides" in 1x1, so I hardly think 11-32 11-speed is that big a deal. It's useful working to improve your useful cadence range, not matter how many cogs you have.

11-32 is 11-12-13-14-15 -17- 19-21-23-25-28-32. The biggest jump here is 15-17, which results in at worst a 6.5% deviation from "optimal" cadence if you shift instantly, perhaps 13% if you lag. Not ideal, but you should be able to produce useful power from around 70-120 rpm.

I see this kind of statement a lot, unfortunately it's often misguided. Being able to get up a climb is not the same as climbing at an efficient cadence.

48x32 at a cadence of 70 gives you 13.22kph ( http://www.bikecalc.com/speed_at_cadenc ... 32&form=no )

13.22kph on an 8% slope gives you 1058VAM. If doing that for a few hours is an easy day for you in the alps, kudos, sir. But it's not for every- and anyone, particularly not in training. And some climbs are long double digit. Doing base miles in interesting terrain is just so much more pleasant than riding around the valleys all the time.

Rant end :beerchug:

Then you can always go 44 10-36 - Is that enough?

But Sorry - I didn't mean to infer it would work for everyone - I live in Canada - not that many really big hills east of the Rockies

11-32 is 11-12-13-14-15 -17- 19-21-23-25-28-32. The biggest jump here is 15-17, which results in at worst a 6.5% deviation from "optimal" cadence if you shift instantly, perhaps 13% if you lag.

Thats 12 cogs not 11. But it really just depends on the rider and the ride. For flat and short hills 11-32 is fine with one CR. As the hills get longer/steeper you will need a bigger range or give up top end speed. Really with a 44/11 on a long day in the mountains you can just coast downhill.

The good thing with a 1 x is you just change out the front ring to change the range, no need to adjust anything.

Maybe he's rocking the Tiso 12sp 8)

Mine's actually a 9sp, so I'm getting 11-12-14-16-18-21-24-28-32. Spending my time at speed on the high half of the cassette, you can see why I have issues. I'll concede the point that it's not apples to apples, though.

I'm not sure why they aren't offering an 11-23. It's super flat over here and I'd really like an 11-23 with an 18. Going to 11sp is pretty pointless since the only thing I'd be getting is an extra 25 which I'd rarely use.

And some of us don't ride in the alps. Obviously a single ring isn't for everyone; it would likely work for me in the foothills where I live; the bigger climbs around here are only ~400m in vertical elevation gain, and usually average something like 5-6% I think. Both of my bikes currently have 53/39 and 12-25 and I get up them on longer rides.

Obviously a single ring isn't for everyone, but I'm with Styrell that it could work for a good portion of the population.

It would be great if SRAM (and the other two mfgs) can provide a lot more options for their drivetrains. That way everyone would be happy.
For now though, SRAM seemed to have initiated the effort of giving more range (and the others are following suit on their own) by having the WiFi concept trickle up from their Apex line to the top-end Red level. Having a rear road derailleur capable of an 11-32 was unheard of until SRAM brought it to the fore... It's a start, hopefully we'll see 1x11 options for road in the future, and 12t cassettes, etc:.
