Tool #1 – Roller / Scuffer
This tool is used for rolling out patches and for scuffing tubes. It’s also handy for rolling out the adhesive tape used when converting a tubed rim to a tubeless configuration.
One end has a roller, the other end is a curved handle with a rasp surface that’ll scuff up your tube so the vulcanizing glue will adhere.
