  1. Doable with a big ratio on a good hill. Ive only gone over 50mph on a freewheel road bike, but that was in like 53:12. If this was an out and back route you would’ve had to walk up whatever hill you hit 50 on.

    Strava gives weird max speeds a lot. There’s no way I’ve hit whatever strava says my max is.

    I’ve hit some weird speeds on strava, if the gps on your phone gets spotty you can get inaccurate measurements. 50mph at 48/16 would have you spinning at 213rpms, which i think is technically possible but certainly is not easy.

  4. Strava had me hitting 90mph once. I’ve never even driven a car that fast. (I have hit 57mph on a road bike going down hill, tho)

    It’s possible – but as others have said you need a big gear and high RPM to get there. When I was a 23yo amateur road racer I could hit 55.5mph according to my cateye in 53×11 down a long steady grade turning very high rpm and speed tucking while on the saddle. I know that a local steep descent I alway tried to maximize I wouldnt get much above 50, but one time strava spiked and said I did 60.4 – I don’t count that Im sure it was a gos fluke. If you put a geared road bike on a stationary trainer, set the resistance low and use your tallest gear you can safely attempt your max cadence. I bet most can do around 180-200rpm, doing that on a bike is something else entirely but makes me think 160rpm is normal for long time fixed riders

  6. You did not do this unless you’re very skilled and have a very large ratio. I ride hard and go on very long rides with large hills. Spinning my ass off bombing a hill brings me to about 37 mph tops. Strava always glitches unless you have all the hardware to actually calculate your speed. Sensors on cranks and things like that.

  7. GPS just isn’t a very accurate way of measuring speed, so the numbers are often wrong. A proper speed sensor will give you more reliable results.
