    Leonardi Racing 942 Cassette 10 speed

    Here we go pushing the boundaries:

    Leonardi Racing 9x42 Cassette 10 speed-dsc7893.jpg

    After the General Lee 3-cogs modification to existing 11x32, Leonardi racing is coming out with a complete cassette 9x42, 10 speed. 9-11-13-15-18-21-24-29-35-42 all in steel, with a version with aluminum 29-35-42. Probably expensive ... but still you can upgrade straight from 10 speed at the cost of cassette + SRAM driver (if your wheel allows it). There will also be a 9-40 and a 11 speed version.

    Looking at the ratios it is quite impressive.

    Single: 32 chain ring 9 x 42 cassette: gear ratio 3.56 to 0.76
    Double: 28 and 40 chain rings 11x36: gear ratio 3.64 to 0.78

    You need a 42 chain ring to get more range, and of course a 26/42 (or a triple) would have wider range ... and so would have a double with a 9x42

    Nice thing with a single 9x42 is that most of the time one would use the 11 to 35 cogs, with the 42 as bail out gear, and the 9 as overdrive. I am actually happy with 30 11x36, and 11x42 would be plenty, but it is kind of exciting to see how many smart solution to the 1xsomething are coming out.

    Good idea and been talked about on here for a 10 spd cassette with a similar range. But I read somewhere in a related thread (probably Budget XX1 and a link?? which I can't find at the moment...) about a 9t cog not being useful with a chain setup such as on a bike. 10 tooth pushes the limits, but the size of a 9 was a disadvantage. Link was an engineering article based on gear reductions etc.

    Ya, it was touched on briefly in the Canfield Microdrive thread:

    Canfield Microdrive 9 tooth cassette

    Not sure if a 9T is needed or not - I barely ever use the 10T on my setup, and cant think of a time where I wished there was one more.

    Does give a nice wide spread of ratios though.

    Thanks Double O, yeah that's it! Usually better at research......

    And you're right, I think the need for that "wide range" 10spd cassette everyone's requesting is growing with the current 1x movement. Thinking it won't be too long before the big S name players will put something together, well Shimano anyway .

    Nice thing in respect to the Canfield is the spacing of the Leonardi Racing. Canfield has 9, 10 and 11: a lot of gears where you need them least. LR has 8 gears in the range we use most (11-13-15-18-21-24-29-35), plus 42, and the 9 overdrive that one can indeed probably forget about in most occasions ... LR is also coming out with a 10x42 10 speed.

    Good model to imitate, and I do wish Shimano came out with something even simpler: an 11x42 ten speed

    (I hope so especially because I am moving to ten speed as we speak .. I'll hate to be outdated in 2 months by yet another 11 or 12 or 14 speed )

    Dont think you need to worry about 12 speed stuff in MTB yet as it hasnt gained traction in the roadie world (yet). I am guessing the whole Di2 electric shifting is going to eventually come our way though. No more cables to mess with.

    Would love to see that for dropper posts. Just sayin.

    I wish there was a derailleur that could smoothly jump up/down from @ 18 or 16t to an 11 or 12t

    Just got a preliminary quote from LR and the 942 will be coming out at around the 380 Euro mark. The upgrade to 942 using LR would be much cheaper than going XX1/XX0 and give you one more gear, but still, big $$$ ... the 42 cog from One Up and Woolf Tooth are obviously way cheaper solutions at the price of two less gears.

    Wont give you one more gear (there is still only 10 total) it will give you one more ratio (and it is debatable if that is needed - early adopters of the XX1/X01 have not reported running out of gearing).

    Agree more options are good though.

    I'd be content with 11-40.

    I could see being pretty content with a 10/38-40 10 spd matched up on a 1x setup for all the terrain conditions where I ride.

    The ratio from 9 to 11 is big, roughly speaking it is close to a drop 14 to 11 with a 28-32 chain ring. That's way I shortcut the comment saying that the 9 will give you two more "gears" in respect to 11. But I agree, unless one is racing or lives in very steep country I am not sure one needs more than 11x42 or 11x40.

    Is it even possible for a mountain RD to have enough chain capacity for the 42 AND be able to drop down to the 9 ?

    33T spread? For sure.
    In a single ring application some short cages could do it.

    9T was tried in BMX - and given up upon - after the hub bodies shredded apart. And these bikes are much lighter and are 1:1, this idea will be soon within the catacombs of failure.

    10spd 13-38T x 35T for the win...

    Any word on when this cassette is going to be available? Last I heard it was to be released December 2013.

    I would really like to try the 942 on my Ti build in conjunction with X9-T2 derailuer and X0 shifter. I have an opportunity to pick-up these other components at half price, but am hesitant to do so without the 942 available. I could build it up with an 11-36 cassette, add a Oneup 42t cog and wait, but if the 942 never materializes then I am stuck with the 11t cog top gear.

    If proven functional the 9t cog would be ideal for my purposes. I could settle for 10t cog top gear if I had to, but an 11t just isn't going to cut it in a 1x configuration. If it did then I wouldn't be looking outside the 11-36 cassettes readily available. I do realize the X01 is available with 10t cog, but I am just not comfortable with that groupset, especially it's incompatibilities and pricing.

    Recon has a 11-40...and its available.

    Thing for me is the slow shifting in the high gears. Its not as simple as Shimano making a wide range cassette. Its also developing a rear derailleur that can handle the 42T without cranking the b-tension that far in. My RD (XT Shadow Plus) does not like to be shifted fast in the high gears. XX1 shifts fast and smooth in any gear.

    The wide range 1x10 will give you most of the range of XX1...but it don't give you the shifting performance...for that...you have to pay to play.

    I currently run the General Lee 29-35-40 on my XTR set up with a 30t up front...works like charm..shifts great throughout the whole range.

    That's nice, but it's 11-42. For me and the riding that I do, I would still prefer the Leonardi 9-42. Plus it's all steel, so it will last longer and it's still pretty light.

    Leonardi announced that they are starting the manufacturing of their 942 cassette. I don't see why you would really need the 9t cog...unless you're planning on riding down fire roads.

    Bet it's going to be expensive.

    Leonardi Racing 9x42 Cassette 10 speed

    Seems to me any chain will be difficult to run with 9T cog
    Old enough to know better. And old enough not to care. Best age to be.
