Subject: New Di2 Shifters advice/confusion Good day everyone,
I've found that new generation of Shimano Di2 only have 1 button on each point, one button for extensions blips is fine, but on breaks there is now 1 button instead of old two.
How do you guys (who uses Di2 ) use this kind of setups? is bike configure fully Synchroshift, is there a risk of chain drop when you are not controlling FD (i.e. switching under load, switching uphill ). Or do you configure extensions for RD and brakes for FD only?
Or its just better to get older generation with 2 buttons on each sides of brake leavers ?
Thank you |
