    Difference between a Microdrive 9t to the XX1 stuff...

    I've been reading about the microdrive hub. This is what I understand of this.

    It would let me put using a 9 speed cassete a wider range of gears and use only a front ring to simplify issues. What would be the difference in that and the XX1 from SRAM? Would using the microdrive be cheaper, more expensive, or something completely different?

    The 9t Micro Drive is what I use on both of my bikes, and I love it. The hub is compatible with 9 speed and 10 speed cassettes, and can be given a very wide range. For 9s you use the shimano caprio cassette and is 9-26t and the 10s uses any of the sram PG 10XX series and usually is set up 9-36t. You can use any derailleur, chain, shifter, and chainring you want, all the hub alters is the smallest 4 rings so they stack on each other. I'm sure you've read the benefits of having this wider range and added clearance due to running a smaller chain ring.

    The XX1 is a similar system but 10-42, and has a proprietary chain, chainring, crank, derailleur, shifter, cassette (which is like $400 alone), so none of it will work with anything else, and nothing else will work in its place. While a good design and probably very efficient, it is also quite expensive as a whole. The XX0 will relieve some of the cost burden, but I still think the C2 system can be had for a lot less.

    The C2 hub can be built with a very cost effective system and is much more versatile. Even if you wanted to add the benefits of the slotted XX1 chain you could use one of the new race face chain rings and the XX1 chain on a regular cassette. Good news also is that the Bro's are now offering full wheel sets with their 9t hub for $500. I think that is just an amazing deal, I am actually going to pick up a set of these for a spare.

    Great explanation. I wish they had the micro drive wheelsets in stock when I bought my wheels in February. It would be the ultimate setup. Lighter than XX1, simpler, and no narrow, delicate chain that is rumored to break fairly frequently.

    We spoke internally about offering 9t Microdrive wheels last season to make life WAY easier for our customers, we just were waiting parts to arrive from our factory. We now have everything in stock and hand build each set to order, in house. We can offer the wheels a few ways:

    9t Microdrive AM Wheelsets
    142x12mm 9t Microdrive rear hub/20mm front hub
    Built with our 26" Dynamal alloy 28mm wide rims
    Front - 820 grams
    Rear - 1000 grams
    Set - 1820 grams
    Shimano Capreo Cassette Tool- TL-HG09 included

    9t Microdrive DH Wheelsets
    150x12mm 9t Microdrive rear hub/20mm front hub
    Built with our 26" Dynamal alloy 30mm wide rims
    Front - 930 grams
    Rear - 1220 grams
    Set - 2150 grams
    Shimano Capreo Cassette Tool- TL-HG09 included

    These two options are $550

    We can also build the above options using our older 28mm Race rims or 32mm Tough rims for $500.

    So what is the range difference between XX1 and the 9t Mircodrive set up with a 28t ring in front?

    Difference between a Microdrive 9t to the XX1 stuff...

    Any idea if you can also use a 42t cog, like Oneups? It would give you the widest range of gearing in a 1x9 / 1x10 setup...

    I've had my eye on the Oneup as well but I'm not too sure if it'll work with the micro cluster. For Oneup's cog to work you have to remove the 17t cog to free up space for the 42t to fit. I don't think micro cluster will allow this to happen, but my fingers are crossed. I'll check it out today.

    Technically the 17t is part of the 4 that gets swapped out for the C2 stack, so you could not remove that one to make room for the OneUp 42t. However, from looking at it I don't see why you couldn't remove one of the larger rings further in. The only issue I can see with this is having too big of a gap in the gearing range.

    11-13-15-17-19-21-24-28-32-36 is natural

    11-13-15-19-21-24-28-32-36-42 is with the OneUp

    9-11-13-16-19-21-24-28-32-36 is with only the 9t conversion

    Potentially... you could take out the 19, or just by looking at it, the best one to remove would probably be the 21. Your range would then be:

    9-11-13-16-19-24-28-32-36-42

    This is just guessing though, I have no evidence that this would work. I'll look at the cassettes and see if its possible.

    I just removed the 19t, put it in behind the 36t to space the cassette, put it back together, threw it on the bike. While there's certainly a visual difference the derailleure doesn't notice it, shifts are nice and crisp across the 6 tooth gap.

    Currently my cassette looks like -

    9-11-13-16-19-22-25-28-32-36 (SRAM PG-1070)

    If is was to go the Oneup route it would look like -

    9-11-13-16-22-25-28-32-36-42

    Interesting, I was thinking about it as well. Wouldnt it make more sense to have the bigger gap on lower gears as TheRage43 suggest? is that combo possible?

    A 11-36 PG-1070 is 11-12-14-16-18-21-24-28-32-36 with the useable part 24-28-32-36
    I'm pretty sure the C2 stack is 9-11-13-16
    So if we could find a suitable 20t cog...
    The result with the OneUp would be 10 speed 9-11-13-16-20-24-28-32-36-42
    that looks like pretty good range with fairly even gaps to me...
    what are the alternatives for a 20t cog besides Miche..

    An older SRAM PG-1050 11-32 may have a 20t cog.. ??
    Competitive Cyclist website shows one but it is out of stock -->SRAM PG-1050 Cassette | Competitive Cyclist
    2013SRAM website does not show that option. So, maybe it is a 2012 or earlier part.. (Apex?)
