With a $2k budget you can get very nice new bikes. For example the synapse in aluminum with 105 and you will get disc brakes https://www.cannondale.com/en-us/bikes/road/endurance/synapse/synapse-105

Is that Sora? This seller is drunk. At the end of last season Cannondale had disc brake Sora Synapses on clearance for less than 1000.

That Cannondale has a better and more expensive groupset. Both frames are alloy. I’d go with the Cannondale. What is much more important here is the sizing difference. One is a small, and the other is a 56cm which is a medium. Don’t buy a bike that won’t fit you. Research sizing on the internet.

I would skip the Cannondale because it is an early disc brake bike using post mount. I would rather have a really good rim brake bike or a fully modern flat mount disc brake with thru axles.
