I'm thinking about purchasing the Shimano DuraAce C24-TL or the DT Swiss version and have read everything about the weight savings, rolling resistance and durability related to punctures however my question for anyone who has them is about maintenance.
Since the "slime" or sealant is in the tires, do you need to change it out from a maintenance perspective? Does it remain in a liquid state for the duration of your next tire change (say, 1k to 1.5k miles) or would I need to add some amounts overtime during routine inflation? Speaking of inflation, does it consistently hold air pressure or would I have to check/add air prior to each ride like I normally do on tubed tires? Thanks for your help.
