Trying to find P5 Disc size, but I'm clearly miscalculating something....
Quote | Reply
Folks,

I've got a 2018 Felt IA 10 size 58 with frame S/R of 559 and 443, respectively. Looking at either a QR or P5 Disc, but when I plug my actual pad stack/reach numbers of 656 and 579 in the cervelo website, its wayyyy longer reach than the size 58. I highly doubt my reach is out of the size realm of the bike as I'm 6'1". I have a 51 speed shop bar so its possible im miscalculating the numbers. Help?

Make sure you're not comparing back of pad measurements to center of pad measurements.
