What tools do I need to remove a bike cassette?
The lockring is designed to hold the cogs of the cassette in place on the hub. In order to remove and replace your cassette, you need to unscrew this lockring. You’ll need three tools to do this: a chain whip, a cassette lockring remover and a large adjustable crescent wrench.
Can you patch a bike tire not tube?
Just a flesh wound Scrape off the dried Stan’s or whatever you have. Rough the tire casing up with some sand paper, put rubber cement on, wait a few minutes and patch it (on the inside). I use tube patches and they work 100% of the time on small holes that the sealant won’t seal.
