Step 4 - Tires and Drivetrain
Using the firm brush and warm water, directly apply washing liquid to the brush then scrub onto the tires removing dirt from between the tread and around the sidewall and rim. Inspect for any damage such as cuts, torn blocks or thorns as you go. Bubbles in the soap may indicate a slow puncture you wouldn’t spot otherwise. Move onto the drive train and the cassette. Remove any grass, sticks or other debris caught between cogs or stuck onto jockey wheels then scrub with the firm brush and cleaner. Tip: Do not use degreaser for this job, if your cassette is so thick in grease and the soap won't remove it you have not been caring for your drive train and the only way we recommend you use degreaser is remove the cassette from the free hub body, that way there's no risk of damage.
