I should have asked about this earlier but does anyone know how tight the chainring retainer ring should be please, my transmission is soaking in my ultrasonic cleaner as I type and tomorrow it’ll all be going back on my bike along with two new tyres and some new Uber bike oil slick valves too, I’m looking forward to trying it all out on Sunday hopefully in the Peak District, anyway I digress, yeah, how tight should I tighten the retaining ring up please, as always any help very much appreciated guys
