Morning,
I am tempted by the Propel. While I can get a great deal on last years rim brake propels that brake puts me off. I also have a TCR disc which I love and know they share a similar geometry. I ride a medium at 5-9 and a half (!) and 29 1/2 inseam and that’s fine with the sloping tube. That puts me in between a small and medium in the Propel. No local shops have a medium so cannot try out the sizing so I wonder if anyone here of similar dimensions has a Propel and what you chose.
Cheers and thanks in advance
