hi all am new to moden trails. first of all how do i fit the rear wheel on my own on my 210 gas gas 250 pro i have to get my wife to help me not ideal but dont tell her that. problem is the brake pads keeping them open why trying to slot the wheel in? the other problem is i had a flat tyred a new rim band no joy so i tryed a innertube. got in in and inflated it ok untill i put in back on the bike. the wheel is not running true is this because i put innertube in? or is it because i put some tape round the inside rim? or as i noticed today silly me the tyre was the wrong way with the harrow going rearwards. it turns round but jumps up then down any ideas guys has this is doing my nut in
