I wrote a lot of this yesterday and didn't post it... Some of it has already been answered, will do a follow-up shortly...
Tools i would definitely go individual, i find a lot in my Lifeline tool kit that i don't need. The benefit though is a nice plastic moulded case for it all to sit in.
You tend to get better quality buying individual - scrimping on tools can mean you damage components. But also getting specific things you need, rather than paying for things you may never need...!
I knackered a chain while breaking the tool, rounded any number of hex heads, bent the chain whip and the cone spanners as soon as I used them on a
PX toolkit very similar. I'm sure when I got mine it was barely £20. But a couple of things in there proved useful in future for occasional use on various other things (external BB spanner, crank remover & spoke tools) so not a total waste. Buying ok-quality specifics I needed for the things I broke, probably worked out at around the same price as the toolset...
Hex wrenches ended up with a
Lifeline Hex Wrench set for £8.79. Not available any more, the Draper ones probably ok. T bars would be nice, but much can be said for a 'no frills' L wrench with a ball end... Just works!
Chain tool bought the
Park Tool basic 'brute' one. Cost me £9.48. Would say the current price of £15 is worth it, mine is 9 years old and done probably 50+ chains.
Chain whip, ended up with Park Tool SR11. Crazy money for them now, wouldn't buy at that price. Heard good things and the neat idea of the
Decathlon, would get one.
Most of those will easily reach 10 years old and regularly used. You get your moneys worth on things you'll use frequently!
Think that's just DUB isn't it?!
So that should be enough to remove and install the majority of the kit? If that's the case then it would be much cheaper to do it myself!
Though this still comes back to how do I route the cable. I'd like to assume that there would be enough room for the cable to go around the top of the BB but I wouldn't know without tearing it apart
Should be enough. Check the hex bolts come small enough - fairly sure for the tops of the Shimano reservoirs you need a 2mm or 2.5mm - quite specific. Small size for limit screws on derailleurs too...
BB press... Hmm! They're an awkward thing - costs a lot to get a good one, but so easy to damage a cheap one, or the BB, or your frame regardless how much you spend.
I'd be tempted to get a different specific removal tool - I've generally always bought the specific park tools one for my BB/bearings. Cost £20-30 but worth it if you're doing it more than a couple of times. Then the BB press although I've got a Lifeline one which is ok, do wish I'd invested in a bigger chunkier one. For the £45 I paid it does feel cheap and it's not going to last. Have probably used it 15 times. But they're also expensive for what they are... A threaded bar with some nuts & washers. Very easy to put together, but also have to know what you're getting/doing if going that route. I'd be almost tempted to ask around clubmates to borrow one?!
As mentioned, get the specific Shimano oil. Just less to worry about. 100ml is enough for what you're doing. I used mine up doing a couple of bleeds and got myself the 1L. It's a massive amount and going to take me years to use! But that kit could be worth it too... The parts in there very useful and soon mount up if you're buying them separately. I ended up getting the little brass spacer thing and some hose stuff from Epic Bleed Solutions, very happy with it so easy to recommend, will use them again for stuff rather than the Shimano branded stuff, it feels same quality:
