Shimano compatibility.

Just a quickie,
I’m building a Specialized commuter and all I need are the shifters but due to the insane costs of Tiagra parts I’m looking for alternatives.

The bike has full Tiagra 4700 10 speed and a buddy of mine is willing to donate a pair of 105 5700 10 speed shifters.

Question is… will it work?

    Seems to suggest that 5700 shifters will work with 4600 series front and rear derailleurs, but not with 4700 series.

    Tiagra 4700 has 11-speed pull, so if you have 4700 mech, you will need to switch.

    On the other hand, I think if you had 4700 shifters, you could fit 11-speed cassette and mech but just have use of 10 gears.

    As above, nope. B@stards / ingenious Japanese* changed the cable pull so 4700 is the only 10 speed road stuff with 11 speed pull.

    Assuming it hasn’t got hydro brakes, you could look at getting the Sensah team 10 speed shifters. They use the SRAM double tap shifting, but are compatible with tiagra 4700.

    That explains a lot. My Pinarello FP1 has Tiagra 4600 10 speed front and rear and I think the shifters are 105 5700.
