i use to have a profile and it was full of grease. so i cleared it all up and put it back together without any grease and hasnt skipped from day one after that till i sold it after a long time.
it depends on alot of factors really. i run mine on about 15 psi with try all tyres that have very stiff sidewalls and i find it to be a perfect pressure. i use to have my tyres quite hard but i realised that having them softer gave me better balance (somehow ) and that i could bounce higher on stuff. its all up to you how you like your tyres JK
oh just put water in it! i know alot of people that have had water in their maguras for 3+ years and its been fine. just make sure no air gets in it. JK
monty brake spray is a gimmick. dont use it. when it drys up it, it goes all a crust white colour that shows up on your rim and tyres and is hard to get off. JK
i think thats the t-master hub so a fixed, same as tarty bikes i think. its a fixed hub but it will not come with a cog or freewheel, so it can be both. its up to you what u want on it. JK
weather looks good on bbc weather clicking on UK then rain then the times of the rain moving across and there doesnt seem to be bad at all. i'll be there at 10.30 ish JK
