Try slowing down? I don't fully understand, I might as well run everywhere then, speed is the thrilling thing about cycling in my opinion.

53 x 19 just feels in a sense too easy though...

For example, I'm cycling along the road around 18mph, I know I am approaching a segment (on Strava app) ahead, I therefore increase my speed but when I keep increasing my speed then around 25-30mph it's like my legs have turned into fan blades they're 'spinning' so qucik
