Yep, cassette tool suits Shimano & Sram

the casette lockring removal tool certainly worked with my tiagra setup OK.
I had to replace the rear wheel and opted for fitting a new cassettem myself but the tool worked well.

yes

Yes the cassette lockring remover works on Shimano cassette lockrings.

It has the required tools for removing Shimano cassettes.

yes, but you need a chain whip as well to get it off

I went a bought a bike repair manual. Haynes and also the rough ride technical manual are good. Both describe the tools and how to use them:)

I suggest you get a book on bike maintenance or join a course (if this is available locally). The book I recommend is the Mag Book called the Ultimate Guide to Bicycle Maintenance.

If you have a helpful local bike shop it may also be worth getting them to do a job for you the first time and asking them to let you watch what they do.

Park tools have a great "how to" site covering nearly all aspects of bike maintenance

Good question, i have bought a couple of bike repair books, they show you the tools and how to use them.
Hope this helps.

Yes it works on Hollowtech II Bottom Brackets. I have just replaced my HT II BB and it worked perfectly.

looking at the image, it has a tool for Hollowtech BB.

Yes, I have used it on one with no problems.

Yes, I've used it several times on my 10 speed Shimano chain.

I've done a heap of work on my MTB ... and I can see no reason why I won't be doing the same to my Road Bike.

Used it on 8/9/10 speed bikes. MTB and Road. Has tools that suit internal and external Shimano BB's.

I've used the chainwhip on my shimano 8 speed cassette without any issues.

Yep, recently changed a Shimano HG50-I 8 spd no probs...just be careful using the chain breaker

No campy tools unfortuentley

I have this set and it really is for shimano bikes, no campy lockring.

I recently replaced my gear cassette and rear wheel (shimano wh r500 and tiagra 9 speed) and had no problems doing so. The shimano cassette ring wrench and chain whip did the trick wonderfully. Cranks I don't know as I haven't needed to replace them but if the 6700 is anythng like my Tiagra then you are going to need a large hex key to remove the crank arms which is not in this set, at least not that I can see.
Otherwise I would say this is a very useful kit and though a couple of the tools I haven't a clue what they are for yet I suspect I may find out in due time.

If you have the 6700 series I think you have the Ultegra series which has the hollowtech crank (google this if you don't know what I mean) The Tool kit comes with the hollowtech crank tool and cap remover. The casette is removed with the chain whip and locknut tool, both of which also come with the tool kit

Hi
It should do the trick.
However if you are looking specifically for a crank remover tool, buy just that, as this set is of poor quality, and you probably have got the allen keys and wrenches already!

No and Yes.

No - You won't be able to remove an older ISIS/octalink bottom bracket.

Yes - You can fit/remove New external bottom brackets like the newer 105 models
