Hi Guys Having my first go at changing tubbies.I have researched abit about the process so hope all goes ok. My question is, how much glue do i need to apply to the tyres and rim? Will be using the continental 25g tubes. The rims will have a little glue from the removed tyres but the tyres going on will be brand new. Im just looking for a bit of a guide...ie 1/2 tube 3/4 tube or full tube per tyre. Oh pls pls dont say to use the tape instead as I am sitting in Bahrain and have NO way of getting my hands on any in time. Thanks in advance for the help. Abbo
