Sorry to be naive - just the front wheel or an extra tube/CO2?
Thx, from the newbie

I would say just bring in your front wheel with the tire and tube that is already mounted. You can reuse the tube that's already inside your tire. No CO2 cartridge unless you want to practice that too. There will be floor pumps there I'm sure.

David - I’ll bring some of my hex wrenches. Should I bring the ones that look like the letter ‘L’ or the ones that look like the number ‘7’?

Thx for that tip, DD. See ya there, with wheel in hand!!
