Opus Allegro 3.0 Carbon Road Bike

Hey, looking to trade my Opus Allegro 3.0 carbon road bike. I just got it, but it’s a size Large and it’s a bit too big for me—I need a size Medium. It used to retail for over $2,000 new, but it’s a 2015 model so it obviously has some normal minimal wear from over the years. That said, it’s ready to ride, has no mechanical issues, and has been kept inside a temperature-controlled house. Mainly looking for a straight trade for a similar type of road bike with a carbon frame, just in a size Medium. If I can't find a trade and someone wants to buy it outright, I'd sell it for $700. I'm not in any rush to get rid of it, so I'm just looking for the right offer or swap. Quick specs: Frame: Full carbon (frame and fork) Size: Large Gears: Shimano 105 11-speed Wheels: Mavic Aksium
