I took my bike for an mot last week and it failed on 1 thing , cracked rear hub , I've replaced that and was taking it for a partial retest 2moro , however today the chain adjuster snapped on the right hand side , will it get through tommorow and pass? And is it safe to ride
Straight up NO. Chain tension is usually checked and as a part of that the adjusters are usually checked.
And just to reiterate what he^^ said...............HELL NO to it passing the test, and HELL NO to it being safe to ride. I'm assuming that the actual adjuster plate itself has broken and not just stripped the thread out. If you know someone with an ali welder you can get it welded. Apart from that it's on to LLexter for a new one
