Does anyone know who in UK will stock a 16t cog for Shimano M771 XT 11-36 cassette?
I'm looking to fit one as part of fitting a 40t Hope T-Rex.
(Rosebikes, the supplier often used for this part, is currently out of stock)
Someone on eBay buys them in bulk and sell for £10.
I just bought a shimano road 10 speed 16t cog for £3 ish and works fine with my XT cassette
Singletrack bikes they were from
I have a brand new OneUp 16t you can have for £6.50 posted if you want it?
If OP doesn't want it.....
Thanks Lawmanx, I'll pass on the OneUp as I want to try and get a M771 specific 16t so the indexing is optimal
Been running the one up version for about 6 months now
I can't tell any difference in shifting, couldn't tell you when I'm in, out or moving over the 16t
It just works as it should, perhaps wouldn't be so quick to dismiss it
Mine came free with the One Up 40t ring which also works fine, indexing is spot on with a medium XT mech, not felt the need for a RAD cage thingyumbob
Iain1775, thanks for the feedback ref the OneUp 16t shifting, much appreciated. In that case Lawmanmx, I'll take the 16t cog, thanks, can you please mail me your details and I'll send payment.
Time to revisit thread... So, I tried a Oneup 16 tooth sprocket in a shimano m-771 10 speed cassette and sadly the result is cr&p shifting across that gear (all other gears inc the t-Rex shift well).
Has anyone a 16t Shimano m-771 sprocket for sale or know of anywhere that has them in stock?
Cheers
Ride on in Rawtenstall have them
I have a Shimano 16T in my XT cassette and I was surprised as to how poor the shifting is across this ring. Most of the time I have to double tap and go into a bigger ring as it just won't change up onto this ring. Disappointed and I might swap it out and try the One-up free one to see if it's any different.
I used a 16t from an old 9 speed cassette as a test and got the same crap shifting across that gear - all others fine. However after a bit of fiddling I found that I couldn't just use the same cable tension that I had when I had the standard 11-36. With the standard cassette there was a slight spread of cable tensions that resulted in good shifting. However when I swapped to the 16t and T-Rex I found to get good shifting I had to add an extra turn or two on the barrel adjuster - basically as much extra cable tension as I could before it affected the shifting. Worked for me... might be worth a try!

They don't hang around for long!!
Thanks for the info guys, much appreciated.
Noted ref other people's experiences regarding poor shifting across the 16t gear....anybody have info why this would be the case on this specific gear ?
Got a OneUp 16t sprocket on mine, no issues at all, as long as its all adjusted correctly and you've a decent cable then I can't see why you'll have issues.
I used the original 17t to start with, didn't have any issues shifting with that either, only changed to a 16t to get rid of the big jump between the 13t and 17t.
Woodentop - I've adjusted and played with limit settings, B-screw and indexing, as well as replaced the cable inner/outer, but I still can't get it to change smoothly upwards across the 16t gear.
Looking through T'internet, it seems that quite a few people have had similar problems with Oneup 16t gear, although many have had no issues (as per you).
I'll try altering the indexing again as per suggestion above, to see if that works...if it doesn't stumped as to what to do apart from try a Shimano 16t....
also suffering from poor shifting, my hacked 11-40 9speed setup worked better 😕
done all the usual adjusting plus a little tinkering, in the end I filed the spacer down a wee bit and "adjusted" the teeth where the shift takes place, it did improve it, and it now shifts half the time as it should.
anyone got a 17t they want to get rid of? seem to have lost mine 😳
Daft question, but are the people having trouble with the 16t 'clocking' it correctly ie sram/shimano cassettes?
Fitted my oneup 16t on a brand new cassette, happened upon a couple of shimano 16t cogs and find both shift as well as each other.
I have got a really annoying bad shift 2 or 3 gears down from the 42t though, it just seems to hang forever going up or down.
I fitted a T-Rex and didn't bother with putting in a 16t, can't notice it - but have found that 10 speed is less sympathetic to the cable not been perfect than 9 speed - a pal reckons it's too easy to have the cable TOO tight.
When fitting mine I did notice that the two slightly cut away sections didn't line up with the rest of the cassette, its as if it needed to be moved clockwise around the freehub body 1/2 a spline, as it is now the cut away section sits just behind the rest of the cassette but move it round another spline and its to far forward.
I didn't think it was ideal, but it works, so not to fussed.
So, I ordered the XT sprockets from cooie's link above, without realising they are 9 speed!! I presume this won't work properly?
Indexing isn't the easiest, never had an issue in the past!
They work fine. |I've got three!! Mate uses one too, with no issues.
So are you guys saying buy the 9spd from the above link ,& it'll work fine in a 10 speed cassette ?.
My Shimano 16t didnt shift as well as the 17t or whatever it was I took off. Im assuming the 16t profile if designed to have different sizes cogs on either side than the ones I had after the Trex + 16t cassette fudge.
@reedspeed. Yes, 9 speed XT from SJS link. I'm using them on 3 bikes with no probs at all.

Don't the shifting 'gates' comprise of ramps on one cog and shorter teeth on the next? If so then a sprocket from a different cassette, even the same brand won't nececeraly worht 100% as the ones above/below it won't be the ones it was designed with. So it'll never be quite right as even if you made a one off that shifted perfectly from below, the gate would then be missmatched into the one above.
The problem i had with shimano xt(10speed) 16 tooth rings is that as its from an 11-32 cassette, the shift gates are in a different position and don't line up with those on an 11-36.
The one up ones seem the same if you go by the little markers o the sprocket itself.
Rotating it round a notch or two to line the gates up with the rest of the cassette sorted the shift issues for both(the shimano sprocket required a bit of work with a file to do this)
Odd how it works for some and not others!
Cool ill order a couple then ,as my one up ones ****ed & slipping !.
If anyone wants to try a 9 speed XT as above, I have one spare (new)
Here you go Shimano CS-M771 16 tooth cassette sprocket.
9 speed cogs tend to be thicker material, throwing all the spacing out and giving whack shifting.

9sp works perfectly on my 10sp cassette. They are less than half the price (from SJS) you are charging for the 10sp one in your link for them too.
9 speed cogs will be fractionally thicker ([url= http://sheldonbrown.com/cribsheet-spacing.html ]0.18mm[/url]). As people have found above, that tiny difference isn't enough to actually matter.
As I mentioned before the 9 spd ones work perfectly. Why pay £10 when you can get them for £4.50 inc postage?. SJS ones back in stock 02/03.
Well just saying they're there if you want the right thing, answering the OP.
I found 9 speed cog extra thickness cocked up my shifting. 10speed chain wasn't keen to come off the 9speed cog.
Great if you found yours flawless.
10speed chain wasn't keen to come off the 9speed cog.
10 speed chains have exactly the same internal spacing as 9 speed chains - it's just the link plates that are thinner so that must have been down to something else - a stretched/worn chain maybe on a new sprocket.
