    What rear mech are you using with the general lee Robin? Interested to see that you got hold of the 42t version, the Shimano ones I’ve seen only go up to 40t.

    I’m wondering whether my Zee rear mech with a stated capacity of 36t will cope with a 40t general lee sprocket. I know there will be sharp intakes of breat at such a prospect but with my current chain length it looks viable.

    Thoughts anyone?

    I’m running the middle of the XT mechs (GS rather than SGS) It seems to cope fine, there’s plenty of capacity and the b-tension easily adjusts to clear the 42t

    Robin, I’ll be doing the 42t (when it arrives) on an XT cassette so any pics/tips on how you set yours up would be a great help!!!!

    Either pics on this thread or my email address is in my profile…

    pics on the thread please! Very interested to see how it’s working/set up etc (and the Dremel work too……)

    No problem, I’ll do that this evening.

    i didnt notice until just now that the shimano version is actually a 42! so its a proper comparison at that end of the gearing for xx1

    please shimano just make a nice 42-11 cassette for 10 speed! pleeeeeease!

    Cheers Robin!

    I’ve already ordered mine. Should be here early next week. I’ve ordered the 40t version. Didnt realise there was a 42t version. Bit gutted! I cant seem to find anywhere the 42t version. Any details of where you got it from Robin? I might resell mine and get the 42t version if it all works.

    Johnny, have a word with this chap, it’s where I got my 42t one from;

    These seem to be in stock at bike-discount.de for 119€ for Shimano and Sram versions.

    O.K, here’s a few pictures of the Shimano one:

    Here’s it installed:

    And here’s a few pictures of the tweaks I made to the tooth profiles with a dremel:
    To help it drop to a smaller sprocket (look at the second sprocket):

    And on the back of the teeth (look at the largest this time):

    And to help it climb up:

    Yes, I know that my bike is dirty and my garden and basement are a mess…. 😀

    Interesting modifications.

    I’ve commented on this before, as my wife has one on her bike & with a mid cage mech it’s been a bit of a pig to index properly.

    I can either have it shifting well on the up shifts, but lazy on the downs, or vice versa. Seems like others have commented on similar issues. Maybe some tooth modification is needed.

    Installed mine today and the “lap of the estate test ride” seems to suggest it works like a bloody charm!

    Long cage derailleur for me, the true test will be done this weekend in the lakes…

    Exactly how mine was behaving. The mods have fixed it, the shifting is more than acceptable now.

    robin- those modifications to the cassette, are you not basically just wearing the teeth out by dremel-ing them?? thats how my worn cassette starts to look after a couple of chains etc

    genuine question, as im intrugied by this but im running a medium cage too and if it needs what looks like you’ve done to it then im gonna leave alone 🙁

    I’ve only taken material off the sides of the teeth and a little off the tops. The very sharks fin shaped tooth was already like that and the material is off the trailing side.
    I haven’t directly touched the loaded surfaces of the sprockets and only the second set of chamfers, the ones on the back to help it drop down, have taken anything off the width of the loaded face of the teeth.
    The rest of the modifications are all on the trailing face so should make no difference to the wear. The teeth are much wider and taller than the standard steel ones anyway, which is probably part of why it hold the chain too well, and I’ve only taken perhaps 20% off the width of maybe 10-15% of the teeth. To be honest unless the chain was worn out the load will be carried further down the teeth than I’ve taken any significant material off.
    It looks like it’s a little worn, but if you have a look at a brand new shimano sprocket, it had all the same shaping, albeit some of it is achieved by physically twisting the teeth which I wasn’t going to do with aluminium.
    I’m not concerned about the effect that my mods will have on it’s lifespan, and basically it came down to it not working satisfactorily without the mods so it’s a no brainer for me.
    It’d be great it they did it at the factory but looking at it and how it was machined, I can see why they didn’t, it’d need a good bit more fiddly work on a different machine and the cost would go way up.
    It wouldn’t put me off buying another if I needed one, it still makes it possible to get a set-up that you have any other way – a super wide range 1x set-up with Shimano shifter and mech.

    cool, glad ya happy with it, you seem confident in it and its life span and as i know nothing about the mechanics of stuff ill take your word for it!

    its defo a great idea in principal and it is identical to xx1 really combined with a narrow wide chainring and clutch mech at a fraction of the price…..and especially as the shimano one is 42 just like xx1 is

    shame shimano cant just come up with a cassette like that, its possible as your pictures show, so shimano should just get the machining tools out and go to work!

    its a shame the leonardi one hasnt worked straight out of the box, its put me off i must say, strange the chap above suggests its worked perfectly out of the box though (although hes running a long cage)

    i probably would have take a punt on one tbh, but now im a bit skeptical as my shifting at the min on 11-36 is spot on

    It is weird that robgclarkson seems to be getting good shifting, whereas myself and butterbean are having the same issue where it’ll only shift well one way in stock form. As far as I am aware there is nothing different between the GS and SGS mechs that should affect shifting but you never know. I’ll have a close look at my wife’s SGS XT this evening to see.
    As you say, it’s a shame that Shimano haven’t just done this themselves though, I’d buy one in a shot.

    hopefully it will work out for you, you’ll have to report back with how it goes

    yep i reckon if shimano made one, it would be circa £200 for a xtr one, £120 for an ‘xt’ type cassette, probably £90 ish for an slx etc

    id pay £120 for a xt cassette with that spread 11-42, i cant believe the leonardi one is £130 for 3 cogs, but its the only thing out there so i guess they can charge what they like, a bit company like shimano could knock them out much cheaper for the full thing

    just hoping they do one!

    I’d love to see Shimano make one, but perhaps the reason they are not jumping on the band wagon is that if they were to produce an 11-42 cassette, would it not make the rest of their drivetrains obsolete to a certain extent?

    Currently intrigued by combining a General Lee with this:

    I reckon with a little fiddling you can get a nice evenly spaced 9-42…

    nah i dont think so to be honest, 10 speed only came out a few years back, not like 9 speed that had been around for donkeys, genuinely dont think they need to make 10 speed stuff obsolete just yet, and i dont think they will

    theres absolutly no need for shimano to do 11 speed if they can produce a 10 speed cassete thats 42/11, the fact sram have gone 11 speed was merely to get the high end 42 cog, if shimano could do 10speed version of 42 i think they would have monopoly as there are way cheaper narrow/wide rings than sram, you can use proper crank arms with proper ht2 bb’s and most people i see out are already running 10 speed shimano stuff

    i think it would actually increase the market on shimano’s side, at least for the immediate future, as alot of people (myself included) simply cant afford a grand to go xx1…..new cassette like the leonardi one 42/11 and if you already 10 speed and use a narrow/wide ring you have an identical setup but just the cost of a cassette (and chainring if you dont have one)

    hell if the cassette was even £200 for a 42/11 (shimano one) they would still sell shit loads as you would’nt have to change a thing if you are on 10 speed already

    Shimano need to team up with Canfield to get a 9-42t cassette. Would be a great range and still substantially cheaper than the sram stuff.

    It’s not quite that simple to be fair. SRAM initially looked to making it as a 10spd option but the jumps on the tooth size were too great to make it work properly for them. Also the mech takes a less than optimal path in order to work over such a wide range cassette.

    It’s pretty extreme when you look at the range of movement required & clearly puts additional stress on it, which is why if you look at the 11 speed mechs they actually work in completely different way in the way they move across the block to help with the shifting & stress the mech is put under.

    There is a market for these 1×11 groupsets, as you will see for 2014, a lot more bikes will be spec’d with them. Shimano are watching closely but they have their own development programme and plans.

    i know its not just as simple as that in the real world, i know it takes testing/time blah blah, but generally the idea that a 10speed cassette can have a 42tooth has proved possible with the general lee, sure it may not be up to shimano standard shift wise, but at least its possible, and with shimano doing something similar it would work much better im sure

    so not reall buying that myself tbh, if a small company like leonardi racing (or whatever they are called) can produce 3 cogs to fit on a standard 10 speed cassette, why on earth cant a global company like shimano with all of their resources produce one??

    tbh they probably along with sram chose not to so yet again the mugs out there (like myself) will ditch their perfectly good groupsets to buy yet another ‘in’ thing

    but im not having that its not possible, out of all the company cycling wise in the world shimano is the one that could do it, yet a little unknown company from italy has done so

    there is a market for 1×11 simply because you cant get the range in 1×10 from either sram or shimano at present, so of course there is a market as there is nothing else out there, but im still sure it would have been possible to do something similar with a 10 speed cassette if they had really tried….

    and with general lee one, its mixed reporting some say it works out the box, others dont….but again thats from a small comapany that doesnt have the means or money to do amazingly extensive research and testing….shimano does

    im not to arsed tbh, im fine with a 11-36 and if shimano did make one id consider it defo, as i know it would work

    but to sum up i dont think for one minute shimano will make a cassette, not a chance on this planet

    if they can create a whole new groupset at £££ to sell to rival the sram xx0/1 setup then of course they are going to go whole hog and create a whole new system, not just a cassette

    Of course, anything is possible – question is is there enough of a market to warrant the development.

    For Shimano, being as big as they are, short answer is probably not. It’s not just a case of designing & making a new cassette as SRAM have shown. Less than optimal ratios, rear mech longevity, in fact a whole new mech needs to be designed to work properly with it, rather than a ‘that will do’ mentality. Then of course there is the issue with chainring size compatability. Standard 104BCD cranks can only really go down to a 32T ring (without funky offsets to clear the tabs), where SRAM offer XX1 right down to a 28T ring, so a new crankset is needed. You might say they don’t need to do all that, just give me the cassette, but big corporate companies don’t work like that. Quite simply, it’s groupsets.

    The likelyhood is you will see an 11 speed drivetrain from Shimano, but not for 2014.

    Excellent info and pics. Thanks Robin. Just one thing I can’t quite work out from your pics, are the mods you’ve made to every tooth or just to few local to the machined ramps?

    Thanks in advance

    I’ll have to take a closer look at the teeth on my Sram one as I’m not experiencing any real shifting problems. It hesitates slightly going into the 40t ring, but it’s just a split second, but the rest shift cleanly going up, and down.

    It’s an awesome set up though. I’m really pleased with mine so far and I’m looking forward to seeing how long it lasts. I might replace the chain a little earlier than normal to reduce wear on the adapter.

    Just back from a weekend in the lakes with my setup…

    Absolutely faultless, had to do a little fine tuning on the trail with screw on the shifter on the fly, but its perfect now…

    Yey, 1×10

    Rob,

    Are you running a medium cage (GS) or long (SGS) cage?

    Been reading up and on MTBR forums someone suggested the 42t cassette runs best with an SGS cage. I’m currently running a GS cage

    Thinking of ordering one from bike-discount this week, and would rather not order a new mech too if I don’t need it!!!!

    I’ve got a long cage (SGS), I was told this was the only option for this cassette… Soz dude…

    Arse!

    Hmmm, maybe you’ll see a nearly new SLX GS clutch mech on the classifieds within the next couple of weeks……..

    If you’re getting the cassette adapter then I’d give it a try with the GS mech… It may be ok….

    andysmiff1
    Member

    Yeah, re-reading the thread Robin was using a GS mech.

    No harm in trying it, and if needs be I could buy an SGS mech if it doesn’t work and flog the GS on.

    Glad to hear its working well for you so far!

    Cheers!

    My set up this morning with a GS rear mech, first ride out shortly. In the stand the only resistance in shifting is when going from gears 3-4 and vice versa off and back on to the adaptor from the Shimano cogs. I’ll see how it settles before I go mad with a dremel :D.

    One thing I did notice is that I had to put a longer b-tension screw in to get the top jockey wheel clear of the 42t ring.

    Will update later on first ride thoughts

    Interesting… where did you find that?

    Amongst Dirt’s Eurobike photos, no more info than that, and nothing on Trickstuff’s website yet.

    Here:

    And they say:

    Trickstuff also had this wide range 11-40 10 speed cassette on show. That’s not too far off what XX1 offers, yet with this you get to keep all your other kit. If the price is sensible on this then it could sell like hot cakes.

    Which makes sense as I don’t think that a 10 will fit on a standard cassette body.
