I’d like Synchro Shift on my bike but it would require a battery upgrade. Do you reckon it would be worthwhile?
It's nice but the shift between rings is still pretty clunky plus I usually find myself manually shifting the rear derailleur to something else straight after the synchro shift.
In other words, it's nice that it forces you to shift the front derailleur at the right time but it's still a long way from seamless sequential shifting.
If you inevitably have to change gear, and the pattern is always the same you can get the PC hooked up and adjust to suit.
I used Synchro for a bit, but never really got on with not knowing when it was going to change on the front, though had I persevered maybe I'd have got the hang of it.
This thread has now got me thinking about gearing... what sort of size and steepness are the rollers? I have a selection of 11-30T cassettes, and do sometimes find myself between gears on the flat.
Like am I going to run out of legs on the way up one and then wish I had the 30T on the way back up??
