No matter what I do, no matter how far up and down the chain stay I put the chain tensioner, no matter how much I vary the height of that while cylindrical pully the chain keeps coming off the back sprocket- I realise I have been doomed from the beginning because my chainstays are not parallel to the rear wheel and the large sprocket at the back- of course it will come off! The two chainstays meet making a V shape with the corner of the V meeting the bottom of the seattube and the two ends of the V getting wider and wider apart as you go towards the back end of the bike
Ignoring the chainstay When I just use my hand to hold the chain tensioner in a position which is in line with the rear sprocket and wheel- it rolls perfectly and there is no coming off at all- it's definitely the V shape chainstays...
solutions?
simply buy a bike which has parallel chainstays in future?
E.g in this video :
It starts off as a V shape but it eventually becomes parallel so it's ok. Is this the only kind which is suitable?
Cheers
