I think me doesn't need 11 speed anymore.
Will that work with a normal derailleur?

$100 for a single machine cog? What a joke.

That being said, I'd be down for a 42t granny gear that actually worked well.

It's expensive for sure, but I don't think it's totally laughable price. What do fancier front chainrings usually cost in USD?

I'm really tempted to buy one and try to use it with a 9-speed cassette.

Although now that I think about it, it would probably need a 9-speed spacer between the 42t cog and the rest of the cassette, which would result in the built in supports not touching the next cog which could end up in a bent cog.

Maybe I should give in and convert to 10 speed to be able to use the 42t cog. But Ithink I would take the 17t and 15t cogs out and replace them with a 16t cog to reduce the jumps between some of the most used gears.

Half as much, it's a joke. You can get two fancy Raceface narrow wide 30T rings for $100.

Pretty good idea. You only have to pay $150ish to build a brand new cassette that essentially is the same range. Compare that to a $400 11sp mtn cassette, and you're saving some good money. I kinda feel dumb for spending so much on the xx1 cassette last week.

and you don't have to buy the sram driver!!! I hope they sell a ton!

ask user mirfe on ibc, he started making 42t adapters half a year ago (and is way cheaper)

there's a BIG thread on "homemade xx1" going on over there:

Those 41 ones on ebay fold like wet Pringles.
And for where I live (and my creaky ol' legs) 41 ain't enough!

 

[sethimus]

they suggest to just remove the 17t cog, it's better to ditch both the 15t and the 17t and replace them with a 16t from the xt 11-32 cassette. this is what most ppl over here do, the result is that the supply of single 16t cogs is now really dry for months

how much use did you get before it folded?

They just added a free 16T cog with purchase: http://www.bikerumor.com/2014/04/06/exclusive-first-look-oneup-components-16-tooth-cassette-adapter-cog-splits-the-difference/
