Tony/Jon,
Ahh, yes, I see.... yes, I'd prefer to suddenly drop to a low rather
than a high by default... hadn't thought about a sudden cable snap...
something else to worry about whilst on the bike LOL (joking, these
days, woohoo!)
I spend a lot of time in the big sprockets too - am wondering if RR is
more useful if on a double chainring than a triple though perhaps, dunno
really.
I'm still working on gear changes while the bike is under load (ie, up
hills etc) - I find it very hard not to have it be a jerky and obviously
stressful for the components (and my knees!) procedure - slacking off
the power through the pedals instantly leads to a drop in cadence but
worse a drop in speed, which is very hard to recover... I know there
must be a knack to it, maybe one part of the pedal stroke is best - I'll
get it one day!
