it’s barely any more expensive. Sarcasm fail, try again.
Nope, not sarcasm…fact…I said it was more expensive…and you confirmed it…even ‘barely’ is more…
Personally I’ve never had a problem with a chain dropping off due to going over rough stuff…admittedly I suspect I’m far less capable than most on this forum, but I’ve yet to ever drop a chain outside over/under shifting and not getting it right for whatever reason…I’ve never ridden along and managed to get my chain to come off over rough stuff. I can’t see the benefit of it (and I’ve yet to ride with anyone who has a chain dropping issue). My last chain drop was a good few years ago (due to skelping a mech to move it on the frame)…it just isn’t something I experience (or have seen happen to anyone else) – admittedly the last 2 years or so have been largely rides on my own so that isn’t going to help if this has suddenly just arrived on the scene…
The marketing is looking for something else to big up and this is nice – I think the concept is excellent, but I also don’t think it is needed.
I’m just waiting on my dropper coming back from warranty work…now that is a definite improvement on the faff of saddle height when you are anal about it as I am!
