Why do road bikes have no suspension?

Road bikes are meant for one thing, to get from point A to point B in a quick manner. So one of the major reasons that road bikes don’t have suspension is because of the added weight. Suspension is a heavy component on a bike, and those added pounds just aren’t conducive to what road bikes are meant to do.

Why do road bikes have rim brakes?

Most bicycles have had disc brakes all along. Using the rim for braking makes a lot of sense: The braking surface that is as large as possible, and since it’s (usually) made from aluminum, it dissipates heat quite well. Using the rim for the dual purposes of supporting the tire and braking saves weight, too.

Will rim brakes be obsolete?

This shouldn’t come as a surprise. After all, rim brake–equipped road bikes have been fading from existence since 2011, when disc brakes first appeared on road bikes. In 2018, eight of the 12 Trek Émonda models had rim brakes; of the 10 models in the 2021 lineup, zero do.
