^^^ Good grief    What sort of hill would you need one of those on?

[tiermat]

What IZ failed to mention is that the XX1 on has one chainring at the front (and SRAM plan it to always be that way).

So a nice range, but not as many steps as say a triple with a MTB chainset.  Or a road triple with a MTB cassette.

[Oscar's dad]

OK, that makes sense.

This is very true, but then I didn't mention it because I was fairly confident that once people noticed the pricetag of the cassette they'd lose interest fairly quickly (the pricing of the other components is also suitably insane - the whole groupset will set you back somewhere north of a grand)

[clarion]

That's a biggie.  I remember when 38t was not unusual on an ATB.  But that was 5/6 speed.

Yep - one of the guys I worked with when I was at University had a touring bike with a Suntour Alpine 14-38T freewheel on it; not sure if it was 5 or 6 speed. Think he used a Simplex rear mech, since that was the only one that could handle shifting up onto the big sprocket, although Suntour did do dedicated rear mechs (Suntour AG, if memory serves - the AG standing for Alpine Gearing or somesuch)

i was using 1x7 and 1x8 setup for about five years now, good to see major manufacturers are starting to understand the benefits of such transmission

I've been running 1x11^* for at least 18 months

I'd read about the SRAM XX1 and been interested in a wondering-if-it-would-work-with-a-double way, as I have a vague plan - just a daydream, really - of building a touring bike with double chainset, as I've decided I prefer them to triples. I hadn't got as far as checking the price. Oh well.

[LittleWheelsandBig]

The Suntour AG freewheel was 5sp 14-38t. The 2nd largest cog was a 28t. Suntour AG mechs were designed for the 38t cog, as was the Huret Duopar derailleur. The Shimano Triple Plate mech coped easily too.

Sram say not as the chainring is sepcially designed to prevent the chain coming off (IIRC the teeth are slightly hooked or such like in a way which would make shifting at the front impossible)

[clarion]

That doesn't make any sense.  What do they mean 'designed to prevent the chain coming off'?  Of course it has to come off - to change sprocket!  The angles on a single ring would be greater than for a double, or even triple, and the shape of the sprockets will have no effect at the front, where it's just a chain going by.

I scent bullshit.

[LittleWheelsandBig]

Longer teeth.

[tiermat]

Exactly, LWaB, it doesn't affect the rear shifting as it's a chainring thang.

[interzen]

I scent bullshit.

I believe the word you're looking for is 'marketing'.

[clarion]

So any normal chainset would work just fine.  Next!

Thank you.  So hard to tell the difference sometimes.

This month's Cycle includes a short review of the Sram XX1, and suggests that the front chainring has extra-deep teeth to prevent accidental unshipping of the chain. As there's no need or intention for the groupset to have front shifting, it's actually quite a desirable feature. I await reports of how well it works in practice.

Edit: of course, there is no reason why it couldn't be used with conventional chainrings and a front shifter if even lower gearing was required!

[clarion]

Or more efficient chainline.

[Cudzoziemiec]

Yep. However, when/if I come to look for such a thing, I shall look elsewhere.

N+1 for me off macb of this very parish

[interzen]

An impeccable choice, if you ask me  

My ideal next purchase is a CrossCheck .... or possibly a Moonlander

I'm so glad it found a good home.  It's a lovely looking bike and you've saved me having leg-extension surgery so I could ride it.

It's a CrossCheck, therefore it is pure awesome fashioned out of iron pipes (fortunately for my bank balance it was too big for me, too)
