Sad, I'm aware, but does anyone know the weight of the new 11 spd wide range cassette please?
I'm interested in this also... Have a 11 speed xt mech shifter and a non microspline/XD wheel so seems like a good option
Doesn't it fall into the "if you have to ask, you can't tolerate it" category?

😂🤣
If you need an 11-51 cassette, are there not other more pressing weight issues?
593g apparently.
593g apparently.
That's the 12 speed one. So that minus the wieght of a cog.
I can tolerate 10% extra weight, but how dare you call my wife fat sir 😉
Cheers all.
about 550g then going off the above as it'll be one of the little cogs missing
If that is the case, it'll be a compelling proposition.
But it'll need a longer mech than the current Shimano 11sp GS ones, won;t it?
I would think so as Garbaruks 50t 11 speed cassettes need a different cage.
righto, ta
might be more useful with the Deore rear mech later on for me then
So it won't work with a xt 11 speed mech then? Bugger, I'll have to get a 11-46 then.
Never say never. If a GRX rear mech will work, an XT may well do depending on your frame

I thought this, too. Then it dawned on me that at that point I’d only be a change of shifter away from 12 speed.
im hoping that wolftooth make a link think for the 11 speed shimano mechs.
12 speed would need the "microspline" wheel, so not an option I'm willing to pay for.
The Deore 11-51 cassette and mech is £47.38 and £37.90 from Bikediscount.de so an affordable proposition. Not worth botching the XT mech for that price.
The Deore mech however is long cage and I like the way the XT M8000 medium cage tucks in out of harms way. Could do with seeing it for real to size it up. I ride on tight trails and durability is more important than ultimate gear range I'd rather stick with my 11-46 if it means having an "Eagle" sized appendage that I am likely to wreck on trail obstacles.
BTW Deore mech is 330 grams XT M8000 GS 271 grams.So if the cassette is about 550g and my 11-46 is 465g total added weight would be 145 grams!
I've just had a delivery arrive from Wiggle with one of the 11-51 cassette's in it, as well as the Deore mech that's designed to cope as I'm not sure the SLX mech that's currently fitted will cope.
The reason for getting it wasn't to get any lower gears, but so I can move to a bigger front ring as I'm finding 1x11 (with a 34 up front and an 11-46) a bit short on high gears on an XC type set-up.
I'm not convinced they've published the weight yet - Reviews all say TBC, Shimano's own site says nothing, and retailers are listing either the weight of the 42T option or no weight at all.
Maybe @epicsteve will get his scales out?
623g according to my scales (that's including the lock ring). I've got an 11-46 as well but it's on a bike so can't weigh that at the moment.
I really like 1x systems but at the weights your quoting 2x with a 36-11 rear cassette gives you a similar range and is now lighter.
I thought the whole point of 1x systems were they were lighter and simpler.
623g for a cassette and 330g for a rear mech is nearly a kg!
I thought the whole point of 1x systems were they were lighter
Not when you start wanting a 51 tooth cog. That is pretty much the same size as a road outer chainring so add 51, with a 46, a 40 and so on and never going o be light. You do save front mech, front mech cable and front shifter though so should still be lighter but never going to be much in it.
Now 1x with a max cog of 32 may make sense for those of us that don't need to ride up vertical hills at 2mph.
12 speed would need the “microspline” wheel, so not an option I’m willing to pay for.
yes! slight oversight on my part.
Wow 623 grams for the CS-5100 cassette, might be more tempted with a Sunrace 11-50 (520 grams) paired with Deore 5100 mech. Looking forward to a cassette review to see how it stands up for it's 320 grams.
I've switched my ancient Enduro (an S-Works one from about 2004) to 1x11 now using that 11-51 cassette. It did end up saving quite a bit of weight compared to the previous 2x9 setup however there were so many changes it's not really possible to tell how much of that was just the switch to 1x11 from 2x9 and how much was other stuff (like changing to an XT Hollowtech II chainset from an ancient Octalink XT one and brake changes 'cause it had been on a dual-control set-up). I even ended up having to change the rear wheel as the Hope hub that was being used came apart when I took the cassette off. I'm pretty sure the wheel I used to replace it with is heavier as well,
Wow - cassette 620g, hub 420g, derailleur 320g extra chain weight maybe 100g and you're VERY close to Alfine 11 weight and still all in the same place.

I've got an Alfine 8 on one of my bikes and the Enduro with the 11-51 on it doesn't feel remotely as tail heavy as that bike does. The Enduro doesn't feel tail heavy at all in fact, where the Alfine bike definitely does.
Epicsteve, what's your thoughts on the overall package in of the Deore 5100? Is the shifting good and is the profile pretty low? What chain did you use please?
I rode the bike with the new set-up on it for the first time earlier and overall impressions were good. Setting the bike up was straightforward and indexing was easy and in use it worked great, with no shifting issues. There weren't any steep technical climbs on the route I did today so I didn't get close to using the lowest gear (didn't use lower than 3rd at any point) so I'll reserve judgement on the gear range for the moment however I think it's likely I'll replace the 32t chainring with a 34. That's on a 26" wheel bike though - 32t is probably ideal on a 29".
The chain I've used is the "Shimano 105 5800/SLX M7000 HG601Q" which is 116 links and I removed one of link from it.

On my old hardtail, I'm running and have been for two years a 11,46 sunrace 11 speed cassette (can't remember the number but, it's the all aluminium one) with a radcage modified M615 shadow + mech, with a SLX 11 speed shifter. The rad cage was designed to reach a 42t range expander cog (remember those days?). It shifts into all the gears no problem.
I suspect a medium caged M6000 will have the range for at least the 46t cog, if you go that way. With an expander link you may get to the 51t cog. Maybe the long caged version will have enough range for 51t cog.
That's a lot of unsprung mass as well. My main concern would be ground clearance, I'm still 26" so don't fancy something thats going to snag. @epicsteve do you have a picture of it in the bottom gear? Would be useful to see and compare.

Its probably the same size as your disc rotor
Definitely works with a GRX mech s I can't see why it wouldn't work with XT

I was talking about the mech. I pulled a standard SGS off my daughters bike as it was sketchy so I would like to see how these longer units compare on a 26er.

I don't have a pic of it at the moment but will probably be out on it tonight and will try and remember to take a photo of it in the lowest gear.
The mech is quite long but I'm not convinced it's likely to be an issue as any time I'm likely to be going quick enough that I might clatter the mech off a rock at speed, I'm also highly unlikely to be anywhere near the bottom gears anyway.
This is what it looks like in the bottom gear:

That looks... ...interesting. I get what you're saying but it still looks pretty vulnerable down there. I'm sure it's not. But still.
@damascus how damn big a rotor do you run?

Looking at that picture I think you might be right. I thought it was about the same as a 160 but actually it might be closer to 180 or bigger! It's a big cassette. 😜

Not so.

It probably depends on where you ride. I did one of the faster, rockier descents in the Pentlands last night and didn't have any issues. The mech would have been miles away from the ground though as I was in the biggest gear.
I did give the 32:51 bottom gear a try on one of the longer climbs last night and it wasn't quite as useless as I thought it might be. I could be useful for taking a breather on a climb as it's low enough to spin a decent cadence at not much more than walking speed. I'll probably still move to a 34t chainring though, as having a slightly higher top gear is going to be more useful than having an ultra-low one at the bottom end. Although I might keep it on long enough to try a couple of really steep climbs that have always defeated me in the past!

That bike has 160's on at the moment and the cassette is a good bit bigger. It really is massive, particularly compared to the 11-32 that was on the bike before.
