SRAM XX1, Thoughts?

**jamal** · 05-25-2012, 02:56 PM

Seems like a neat idea. In a couple more years everything is going to be 11spd and a couple more after that it'll probably all be electric. The only bad thing I have heard about di2 was when a guy left his battery at home.

It will be interesting to see what affect this new front ring, chainline and that massive 11th cog have on friction.

The big cog isn't the issue with friction. Going smaller than 13t has a measurable decrease in efficiency because the chain bends so sharply, and chainline won't be any different than any other 1x setup or staying in the middle ring. Cassette doesn't get any wider the gears just get narrower and closer together.

so 32x42 is the same as what?
always nice to have fewer moving parts, not have to deal with makeup shifts and timed shifts, etc.

**jamal** · 05-25-2012, 09:37 PM

around 22x29 or 24x32
those are the common mtn little ring sizes right?

Or find some Suntour Micro-drive 20t cranks!

Thoughts?

Eff it. I'm going singlespeed.

FIFY...

this might be good for some riders who will always shift in the easiest gear on the rear, but stay in middle ring for the climbs. (just as their default setting) makes them think more about how steep the hill actually is, and what cadance, and gear is right for that hill, rather then "oh shit, hill, must shift down"

thinking this, as a XC set up, on my wifes full 29er might be an answer. Have to see how brutal the price is, and if the bikes that have this as stock are more enduro, or more for the XC crowd...

I was happy with XT circa 1991, with 22/36/48 x 12-28 (7-speed) -- Avid microadapter with a Suntour microdrive chainring.

I am running 3 year old 2 x 10 XX and it rules. I had 1 problem and they warrantied it, the top 36 cog folded over once, a 2 tooth section. I would like and even lower gear for the very steep short climbs in Hawaii.

38!

**Wolfmansbro** · 05-29-2012, 03:29 PM

I find the new chainring teeth to be the most interesting aspect of it.

**mntlion** · 06-01-2012, 09:40 PM

does any small companies make a huge range 9 or 10 speed cassette now? I remember someone making a Ti one, with a huge range?

I'm all in on the idea, but I'm not sure this is it. I was stoked on the cassette range and only 260g (thought it would end up like a big wheel weight). Then I read it takes a special hub. Suck. Also not a fan of more compatibility issues with the crank/chain. Would like to run whatever cranks I want with a bash so I don't mash my chain when I inevitably fuck up some ratcheting. Maybe you really can, and that's just SRAM marketing to get you to buy the groupo?

The RD sounds great in concept. Would like to see some long term reviews though on how it holds up against a Shadow Plus in fighting chain slap.

The solution to a problem that doesn't exist.

One thing that IS pretty cool about it is the derailleur's parallel design where the chain remains the same distance from the chainstay regardless of which cog in the cassette you are using.

**Yeah!** · 07-04-2012, 03:27 PM

I was driving home from the trails today and the car in front of me was a dropped '88 Civic wagon with fancy wheels, big exhaust, and aftermarket tailights. There's an analogy in there if you look for it.

For my area, 2x systems suck unless one of your gears is a 32 or 34. Otherwise, you're constantly shifting between the two front rings. I'm with Tyrone - switching to SS solved all my problems.

**beaterdit** · 07-05-2012, 11:24 AM

I think it looks good. Only thing I'm lacking on my 1X10 setup is a super granny gear for the really big days. I don't notice the lack of top end that much. Either way this system gives more of each. Realistically though, just having a 38 instead of a 36 in the back would be enough but more range prolly isn't a bad thing.

I agree, not sure why anytime some new drivetrain innovation comes out everyone shuns it. The same thing happened with 10 speed, and now everyone uses it and everyone I've talked to loves it. I personally wouldn't pay for the XX version, but this will trickle down into X9 eventually and will probably be on my next bike.

**mntlion** · 07-05-2012, 01:16 PM

nice to see all the F ring options with the 11 system, wish it was a 11-43 cassette that used a standard hub, rather then a 10-42 that needs yet another special hub

**Anospa** · 07-05-2012, 01:18 PM

Yeah, that's where they lose me. I just got blingy hope wheels. I'm not gonna be inclined to switch from them anytime soon.

**beaterdit** · 07-05-2012, 02:17 PM

I bet Hope will make some compatible conversion for their latest hubs. But yeah, why not just even 11-42, or even 11-38?

its a solution to a problem that definitely exists.

sucky thing about 29ers is the CS has to long as hell to clear the FD, relative to a 26er.

no FD, no problem.

of course, when you put this on your 450mm CS bike as an aftermarket part, doesnt really help, it needs to be OEM.

Adding 1 on the top end does not add as much as 1 on the bottom end. So to get the range of 10-42 with a current hub it would need to be 11-46. But either way, 11-42 would still be just fine for me.

**toast2266** · 07-05-2012, 02:47 PM

Needing a new hub / freehub body is what kills it for me. Other than that it looks great. The aftermarket should really make an 11-42 with a standard cassette interface. I'd buy it.

**marshalolson** · 07-05-2012, 02:57 PM

there is no reason they cannot offer a 11-38 or 11-40 10spd setup, which would work with all existing standards, and they could crush it with, since its perfect with a 32t front ring.
