Owning these two bikes is a bittersweet affair. The sweet part is that they both retail at the same price and come with solid features. The dilemma is that I am struggling to pick a side. I love both bikes and their nimble reliable performance. Anyway, since we have to pick a winner, I will have to go with the Trek X-Caliber 8. It feels lighter and easier to handle. I can also fit 29” wheels on it giving me more traction for better handling. As a successor of the Trek X-Caliber 7, this bike is value for money.
