I’m running a 23mm wide front tire on a pretty wide 80mm deep rim and it looks fast but there is a fairly large lip between the tire and rim. What do you put in there? Silicon sealant or something? I’d like to be able to peel it out of there in the future without making a huge mess or damaging the t…
