I quite like the idea of having friction shift on the front - STIs don't shift as well if you're using non spec rings, or if you have older rings without pins/ramps. Also being able to shift to friction mid tour if the indexing goes way off would be useful.
These considerations mostly stem from our tandem where cable runs are long and the derailleur springs aren't always strong enough against the friction of the housing, but I want to cover the brakes and be able to shift. Bloody things!
So I've been wondering about the Retroshift Gevenale for a while now, as far as I can see outside of racing/riding cross where the potential to break the shifter is high and replacement cost could be lower, they are a bit pointless?
Google also sort of confirms this, as far as reliability is concerned I've been using Sti's for around 6 years and haven't had a failure yet...
So, whats the point?
A genuine enquiry, not being snarky.
