Yes GRX is nice, but sadly not a lot of bikes come equipped with it yet. Probably because it is still fairly new.



Oh wow, that is a good point on the Sora Topstone. I had no idea it had a square taper crank! Thanks for letting me know! I was turned off on it because of mechanical vs hydraulic disc brakes, but that is another no go.



Thanks for the feedback. Yeah Tiagra seems great value, and the 10-speed interchangeability is a plus for me as well. Although 10 speed things are starting to become harder to find. 105 5700 groupset parts are on their way out I think..
