I would say the prep station by topeak is a better tool kit for the money (also v expensive mind). Speak with your LBS and see if they’ll do you one cost as its a community project.

If you get a trade deal I would go for a Pedros bench in a box. Perhaps see if they will sponsor your project by way if some free tools? Good PR is that.

you’re buying quite a lot of “ordinary” stuff in that Park kit – allen keys, cleaning brushes, rubber mallet etc. I think you could find better value fairly easily, but it might not all be the same colour

What do you need ?
Headset/BB press – unior are massive, bulletproof, versatile and a teeny bit expensive (v expensive in comparison to a threaded rod and some imagination

Nice big vice (if you can sell it as bike-specific)

BB / headset knocker-outerer

BB thread tap if these are old bikes

Compressor (or airshot / homebrew option)

Grease gun or two

Bleed kit / bag of syringes & tubing from a pharmacy

Couple of good ratchet “screwdriver” handsets with set of hex/torx bits

That park kit looks hard to beat for the money.
I would suggest that you look at what is included and how/if you could use it. If there are even a few items in there which you think you may not use, price up some alternatives. For non bike specific stuff, there are always great deals to be had on good quality level hand tools and just buy the bike tools you’ll actually use.
For example, you could buy this;

And still have plenty of money left for bike specific tools.
For an extra £100, you get the set I bought (or same if you’re VAT registered?);

I only have a few bike specific tools really but there again I don’t use cone spanners etc.

You’re not that outfit in bristol are you? if so, I dropped in some bars and stuff a couple of months ago!

Id not bother with the park branded brushes mallet etc
At work we use a whole range of stuff
Spanners screw drivers are halfords own or lidl
Cyclus for headset press and good value bb taps etc

Park for chain whip pedal spanners and third hand tool / cable puller also chain tool ct2

Shimano do good tools also

Cable cutters for me knipex same as circlip pliers and normal pliers.
Ison distribution do loads of tools

Bit rambling sorry

If you get lots of cheap bso stuff get a proper fixed cup bb tool for the drive side cup on loose ball bbs

I bet you’ve got heated seats as well as heated wing mirrors, haven’t you? 😀

Gas blow torch. This thread has made me realise just how much stuff I have collected over the years

large socket breaker bar can be useful to save struggling just get a large socket to fit over a bb tool

I volunteer at something simialir.

Any tool that’s usually bought on the cheap doesn’t last. Especially if your putting force thought it. Eg. Chain whips, cassette removers, cone spanners BB tools…..etc…. Buy decent branded versions of these types of tools and more importantly makes sure your volunteers know how to use them correctly as even good kit is wrecked when not looked after.

For 90% of the type of bikes we work on I use , my own allen keys and a knippex spanner then the shops cones spanners, cassette and bb tools and occasionaly a 4th hand tool.

Some good 15mm spanners would be good as these are used a lot as well.

I’d say buy individually rather than a specific set as you’ll get more of what you’ll actually need.

For hex keys bondus are cheap and very good

And these are worth their weight in gold for cartridge BBs!!!
