    I did have a 2×10 setup with 52 & 36T front chain rings.

    I’m upgrading to ultegra di2 2×11 and I have a choice on chain rings sizes.

    I mainly ride club runs of a Sunday 50 miles or so and 100 mile sportive rides. The Cavendish tour100 ride was very testing last year and used every gear I had. I’ve asked the shop to order the same what is on the bike but not sure whether 50×34 would of been a better choice? Or wouldn’t I notice?
