I am sorry to say the later - I've had the Anchor since 2001 and never had a chain come off - frame looks like new- but saying that not been looking at magazines etc for some time so not aware of these things - Ordering one ASAP just to make sureor they are unaware of the dangers.
Well exactly. Instead I'm left sharing a room with a guy who says that he "Ain't wearing no damn 10 speed Dura-Ace chain". I'm sending him back.If only a sequence of events had taken place along the following lines, helping you achieve your goal...
1. The people who made the item you bought had also had the foresight to write a manual which you could read.
2. Someone had developed a service on the internet where you would search and instantly find the answer to anything ever in the history or ever.
3. Someone had posted several massive close-ups of chain catchers fully installed on professional racers bikes by the profession mechanics of said professional racers.
@gunj I'd definitely be using a catcher for Di2 . Seen Eric jump his chain far too many times! And with Di2 you cannot manually 'catch' the chain as you can with std cable system. You are stuck with a 100rpm cheese grater.
Sent from my chisel and stone.
