had a daft incident yesterday. turned uphill, shifted down at the front and down at the back, but at the back the chain just went all the way into the spokes? i say spokes, but i have a spacer on my cassette so it just got stuck, no damage to wheel or anything. so i was spinning away, panicing, unable to unclip. did a slow motion fall. tried to fix it using limit screws but every time the chain would just fall off into the direction of the spokes. eyed the rear mech hanger which looked proper wonky. luckily i carry a spare with me, was able to fit it and continue riding with just the loss of my lowest gear. fixed it today with a combo of micro adjusting the di2, b screw and low limit and its shifting perfectly again, but i am weird paranoid it’s suddenly going to jump into the spokes again
