Only if your going 1×10 and getting a wie range cassette.

Otherwise just pick up cheap 9spd stuff

Upgrade? My bike’s got 27 gears. I remember when it was all about how many gears you had. How long before we’re told/sold we all need 3 speed Sturmey Archers? 😆

Not really noticed much difference going to 10 apart from it looks like parts will be a lot more expensive!

Like some above, I wouldn’t class 10 speed as an upgrade, maybe if you want to run a single chainring. I put together a road bike for a friend recently which was my first experience of a 10 speed chain, its side plates seemed to be made of foil.

Tried it last year on one bike but in the end sold the groupset and went back to 9sp so I didn’t need to carry two lots of spares.

I liked it, especially the ability to ride up more in the middle ring, but it wasn’t a big enough improvement to justify upgrading all my bikes so I have stocked up on 9sp mechs and cassettes instead.

While 10 speed setups give a better range of ratio e.t.c, chains are more expensive and so are the cogs.

If you live in a really hilly area then you there is probably an advantage. If you you in the flatlands then the benefits are less noticeable. I only ride SS MTB though so my opinions are biased.

I did, I wish I hadn’t bothered as replacement parts are a lump more expensive. That was a 3/10 setup.

I agree with sam_underhill, I thought XT dynasis 3×10 was really slick feeling, a lovely shift action at the lever and I felt the chainset ratios were better, less adjustment needed at the rear when front shifting so the result was I used the range I had more willingly. A sucker for the hype, or the idea behind it works? I’d say it works. BUT I hardly ride it anymore, I smashed the RD off last summer and it sees a lot less use than my SS, so I can’t comment on durability. I’d guess it’d all wear well as you may use more gears, ie spread the wear across rings and cassette a bit more? I’d spend the extra on good shifters and use a cheaper RD.

Yes. The shifting is slicker, you can shift better under power, the shifting stays sweeter for longer on Shimano (though strangely the opposite is true for Sram) and the extra spread of gears for 1×10 is useful, if you run 3×10 the tighter ratios make life easier.

Also, contrary to what those above say, there’s tests (and my personal experience) to show that chains and cassettes last noticeably longer.
