Has this been done? ( disc brake content )

[SoCalSteve]

Hi all,

This may be a stupid question and maybe an obvious answer that I’m not seeing, but I will ask it anyway...and flame away!!!

On a rim brake bike, what would be the ramifications of replacing the fork, brake caliper and left shifter to a hydro disc brake set up and leaving the rear brake as a rim brake?

As always, thank you all in advance!

Steve
