As it says really, will a normal XT/XTR 9 speed mech fit a 36T cassette?
Looking to temporarily fit up the road bike ( which is 39/53 on the front ) up with a much easier set of gearing. I figured that I could try an mtb mech on the rear and a wide range cassette which would cheaper than changing to a triple setup.
9 speed Shadow rear mechs are rated to 36T. Non-Shadow are usually rated to 34T only.
I thought 36 was 9 speed only - can you get 36t 9 speed cassettes?
I'd go for a compact crankset if it were me
its a 10spd setup road bike. was looking at something like the SRAM PG1050 12-36T cassette - which would give me a 1:1.09 ratio on the 39T front ring which is what i'll need. I'm no lightweight by a long way and having done my knee in last time, I'm prepared to sit back and take it a lot easier this time.
STI are shimano 10spd Dura ace, so I need a 9spd mech to keep the correct cable pull ratio.
Changing to a compact would involve a new crankset and poosibly front mech which would cost more than a change of mech+cassette.
Shadow mech ... ok - wasn't aware of that. Will look at that a little more closely.
I have a 9 speed 11-36t XT cassette with a 9 speed shadow SLX rear mech, medium cage and it all works lovely.
If by 'normal' you mean the older non shadow type, I could not say with any authority whether it would work or not.
£80 at Planet-x?

I know it's SRAM on a shimano setup but you could always tape over the logo's 😉
can you get 36t 9 speed cassettes?
Yes, you can get HG61 9 speed in 12-36T
You could pick up a Tiagra 10 speed compact chainset for around £60 and your front mech will work fine with it.

No you don't... You may have an HG61 where you've swapped the 12, but it's not an XT.
thats cheaper than I thought i suppose. but does it really buy me much ratio?
road rear mech goes to about 28T max. At the moment I would have: 39/28 = 1.39
So even with the APEX it would be 34/28 = 1.21 and even then I'm not sure that a dual front mech can reach between the 2 front rings ( edit: I see above that it should work )
the mtb setup would get me 39/36 = 1.08 - which is really very good.
then I have the top end. APEX would be 50/11 = 4.54
whilst mtb setup would be 53/12 = 4.41
Its the low end ratio I really need as I dont really spin out at the top end. The mtb setup gets me more low end and minimal difference top end.
Bust my leg and slowly recovering so set road bike up a la mtb, this is me , Ultegra 10 spd shifters
105 original front mech onto 105 50x34 chainrings
9sp Deore rear mech onto cheapest Shimano 12x36 10spd
cassette
Cheapest Shimano 10 spd MTB?? chain
admittedly alot of that stuff I already had in spares box, it all works well but on the 36T cog theres not quite enough 'B' screw adjustment so jockey wheel can touch some times but dont use 36T much.I would add that Shimano gives best low cogs, Apex jumps too fast if you have bad knees etc. Unless the newer ones have better ratios.
thanks for the reply. hope your leg is getting better.
regarding your rear mech, what that a normal style mech or a shadow type?
Normal not Shadow , one I already had , dunno if Shadow runs or not, it has a different cable pull and route out the back, however the 9sp works well with 10 sp chain and cassette even tho the nay sayers said it wouldn't, just try it, good luck.
