I weigh 205lbs and ride in the Midwest. Currently riding a Canyon Endurace CF 7 bike with the stock wheels. I acquired 28h Shimano RS770 hubs. My current tires are 30mm front and 32mm rear (as shipped on the Endurace). When they wear out I'll probably just go 28mm GP5000s.

I was going to get AR46 rims (21mm inner, 28mm outer), but seems that aerodynamically these are better for 25mm tires.

AR56 seem to have a better 23mm inner width and 30mm outer width which seems like a better match for 28mm (or 30mm) tires. But 56mm depth is getting up there and I don't want to be miserable during cross-wind rides.

Some believe I should be going WR-series rim in the front like the WR45 which is a 32mm wide outer (25mm wide inner). That seems a bit wide for a 28mm tire?

Maybe I should just get AR56 and hope my 205lbs makes crosswind riding stable enough? Or not worry so much about tire widths and just get the AR46?
