9 speed/10 speed comapatibility

Hi
I'm trying to buy a second hand pair of 105 shifters, and was wondering about compatibility -
Is right hand 10 speed shifter compatible with a 9 speed cassette?
Are left hand triple shifters compatible with double rings?
Not sure yet whether I'm going 10 or 9 speed (9 preferbably....don't want quicker wearing thinner 10 speed stuff....which I assume is pricier?)
Cheers

2/ It will work but may not index quite right.
10sp does not wear any faster than 9sp. The only real difference is the chain is narrower on the outside. The rollers, etc are almost the same.
The shifters are the most expensive part of the group so if you can get 10sp reasonably cheap then go for 10.0 -

If you use 10s spacers in the 9s cassette it should work (with one redundant click,

The sprockets are held together by rivets. Remove the rivets and you should be ok.0 -

which can not be split so this is not really a feasible.

Anyway,,,, a cassette lower in Shimano's range (or something compatible) will do.

So, get a 9 speed cassette and new spacers, butcher it about, fingers crossed and voilà, or maybe just get a 10 speed cassette and chain, job done!0 -
So he gets his 105 10sp shifters and then buys a set of 10sp spacers, a low spec 9sp cassette and new chain to go with it. He then has to find a spacer to make the cassette fit the freehub. This is just a bodge. Far better, and cheaper, to get a 10sp cassette and chain as that is all he needs to complete the job. The mechs and chainset will work fine.
It is not about opinions. When people ask for advice you should deal in facts based on makers specs and practical experience (which shows you can often push the specs).0 -

Hm looks like I opened a can of worms there!
Ok, looks like I'll be going 10 speed then, I'm not keen messing around with spacers!
BTW, is there any real benefit from 10 speed....or is just a another ''make something new'' scenario?

Think so mate lol.
TBH your better off just getting a 10 speed cassette...their not silly money.
Your not notice much difference 9 to 10speed....gear spacing is a little better but can depend on how you ride / cadence. 10speed wont make you go faster lol.
How much you got to send on a cassette ? I have a few near new 10speed cassettes (think SRAM 1070s) if your interested send me a PM0 -
PMd you cheers0

10sp gives you one more gear ( ) but this usually means filling in a gap in the middle of the cassette. For instance a 9sp 12/23 looses the 18 which is a very useful gear especially in races. On a 12/27 you loose the 16 as well so you get wider gaps just where you don't need them. My ideal would be a 50/34 with 12/27 11sp. Straight through from 12 to 19.
Also 9sp will get more difficult to replace like 8sp is already.0 -

Good point - 10 speed it is then!0
