A lot of the tools in the kit seem redundant if you already have a "normal" toolkit at home.

I did what the other posters suggested. I bought them on an as needed basis.

So far the bike specific tools I have:

-cable cutter
-chain whip
-lockring removal tool
-chain breaker
-chainring nut wrench
-steerer tube cutting guide
-chain measuring tool
-caliper alignment tool (for the MTB's)
-Ritchey Torq Key for stems and seat clamps
-pedal wrench
-1/4 drive torque wrench from Price Point for bolts requiring more than 5nm.

Then the typical pliers, hex, torx, etc from my normal tool box.

I'm thinking about picking up a couple fork specific tools. I got three MTB's that use Fox forks and one Marzocchi...and at 80-100 a pop to service...the tools will pay for themselves after the first service.
