Cyclocross Race Day Tool/Part Box

Hi All - I’m working on putting together a small tool kit/parts kit for cyclocross race days. I’m thinking like a fishing tackle box size type of thing with basic stuff to potentially repair minor issues given my limited mechanical skills. Things like snapping a chain during warmup, swapping out a derailleur hanger when I inevitably crash during pre-ride, minor brake rotor adjustment if rubbing, etc. FWIW, I’ve got a specialized crux with SRAM force AXS drivetrain/brakes. Here’s what I’ve got so far and I’d love to hear what I’ve forgotten or what you all have found useful.


  • Good multi-tool
  • Pliers
  • Valve core remover, sealant syringe
  • Grease/lube
  • Rags
  • Zip ties
  • Electrical tape (or some other multi-use tape)


  • Coin battery and quarter for brake battery changes
  • SRAM battery charger or spare battery
  • Boa string
  • Tires and sealant (in case the course or weather is unexpectedly different)
  • Extra tubeless valve (or 2)
  • Spare chain and master link
  • Derailleur hanger (or 2)
  • Cleats and studs

Thanks all!

I’d bring a real set of Allen keys instead of the multi if your bringing a tool box in your car. I do the same but for every ride I do that’s not leaving from my house.


I guess the only thought I’d have being an eTap user is to bring a spare battery and not a charger. If it’s 10min before race time and your derailleur isn’t working, you won’t have time or an outlet to charge from.

Agree with real Allen keys too

And co2, if you need to set a tyre. Also tyre levers. Or are you on tubs? Then tub tape for quick fixes?

Does grease include rt85? Quicker to give things a spray if they’re stuck

Brake pads.

Oh, and safety pins, and spare bar end plugs.

Apart from the real allen keys, a torx one for disc rotors. If you intent to true a rotor, an adjustable spanner (or the proper park tool).

Scissors and a hole punch for “adjusting” race bibs/number plates.


That is a lot more than I typically bring.
Allen Keys
Chain Whip
Lock ring tool
18-20 cogs
chain lube

If it is going to be a wet day I just bring an extra pair of cheap mtb shoes.

Half that crap just rolls around in my truck from the start to MTB race season until I am done with 'Cross season.

Kit for a quick brake bleed.

Thanks all! These are all great. I appreciate the insights.

Some pliers have cutters built-in, but I’d also add have a pair of knippers with me. These are super helpful when cutting cable ties (e. g. for your race numbers) as well as various other things.
