This is probably the wrong place to post this but I thought I would give it a try. This is a special road bike. Although a little older (1990's) the bike was repainted by the factory and all components were upgraded in 2018. 3D is a small boutique manufacturer in Durango, CO. The company was started by Chris Herting the first welder for Yeti Cycles. The frame is aluminum with a carbon fork. The drive train is Shimano Ultra. The bike is missing a seat and post. I could throw a seat and post on but figure a seat is a personal choice and the buyer would probable want to replace anything that I put on there anyway.
