Last night, replaced chain on bike, turned crank a few times to check all working well and tweek the gearing.
This morning, head off to work, few pedal turns then nasty noises. Chain has split, rear mech is wedged into rear wheel with a spoke jammed in by the lower jockey wheel, barrel adjuster snapped clean off.
Removed the chain and the rear mech in now pointing towards 11 o’clock, mech hanger bent so much it’s almost touching the cassette.
Gutted, can’t get it into the bike shop until Monday either so no riding until at least next week, assuming they think the hanger can be bent back.
Gutted, that is all, needed to put it out there. Will take more care putting pin into chain next time.
