GRX400 STI using GRX810 FD+FC on a 2x10 setup question
Hi guys... I'm a newbie here. I've been trying to search for some answers regarding this itching question about mixing GRX versions. I've seen a Tiagra 4700 STI work on an GRX812 RD and 10x cassette. Knowing that Tiagra 4700 has the same cable pull as the GRX400, would the same concept work if I replace the Tiagra STI with GRX400 STI? And if this setup works, would I be able to use the GRX810 FD+FC but keep it as a 2x10 setup? I know this may be confusing, but I know there are gurus here that might be able to answer my silly question. Thanks in advance.
