Cassette Adaptors

Hi Guys,

I've recently switche to a 1x10 drivetrain. I like it but i yearn for one extra gear for the climbs. I run a 33t front ring with 11-36 XT rear cassette. I can manage the climbs and i find i have plenty of top speed on my trails but i would really like a touch more range for some steeper climbs.

There are options. The One-Up cassette adaptor is ideal but its not available until the end of February which just seems so far away. I dont fancy the general lee adaptor as its just too expensive imo and i dont want to lose the 36t ring for a 33t.

So does anyone know of any other options, i think this sprt of thing will become more common from more manufacturers soon but i would really like something within the next couple of weeks.

Any ideas?

Thanks.

    I like the simplicity of 1 x 10 plus the lightweight. As soon as i get the narrow/wide ring ill be dumping the chain guide too.
    Just want one extra gear, i know its doable just looking for alternative options.

    Wait 6 weeks? Unlikely to kill you.

    32t chain ring? You won't get a 33t narrow/wide, so that'll give you more at the bottom end.

    PLEASE don't ask why you won't get a narrow wide 33T!

    32T or possibly 30T seems to answer your requirements.

    There's some guy on ebay been doing them for ages now; solid steel (single 42t cog weighs about the same as a whole cassette) and many reports of them bending though.

    Yeah its ok i know i wont get a 33t narrow/wide. Ive got a 33t renthal ring up front.
    Ive just ordered one of these and will see how it rides befre deciding whether to go with 34t or 36t narrow/wide up front. Should give a nice range.

    Why did you order a 33t when you're considering a 34t or 36t N/W, wouldn't one of those have made more sense...? :?

    I run a 34t works components chainring, WolfTooth are bringing out a version, absolute black are doing a 40t version and I imagine there will be others too. Given what I've read on the OneUP adapter, depending on the bike it can be a bit of a bodge to set up, so I think a 40t would be better for current dérailleurs. I think we'll see something from Shimano at Sea Otter though, so it might be worth waiting a bit longer.

    Sorry, why can't they make a narrow wide narrow chainring in 33t, and have a standard (non meshing) 33rd tooth? I doubt that would interfere with the chain retention significantly...

    Yeah, I understand that the thick thin teeth can only be even, but couldn't they put a non specific tooth as the 33rd one?

    As the chain is goes in even steps between narrow and wide, so does the chainring if it's narrow/wide. Adding a normal tooth would just add a huge amount of fail. Tbh I use a 33t E-thirteen chainring on one bike and a 34t narrow/wide on the other, same cassette and I notice almost no difference between them.

    so after that the 34th tooth (number one second time around) would need to be thin when it was thick (I could think of a comparison here) on the first rotation, are you taking the pee or setting out to look really really dumb?

    The 33t came on the bike so im happy with it for now.

    I've gone ahead and ordered the one-up adaptor just gonna have to wait by the looks.
