I took the mid drive (Frey CC) and hub (Espin Sport) out for back to back spins today. I rode the Sport about 15 miles (95% street and sidewalk) and the CC about 10 miles. (50-50 dirt trails/street)
I think I need different tires for my CC as the Schwalbes did not feel super stable in sandy conditions. The Sport just keeps on keepin on and offers a great comfort ride. I of course have added the suspension seat post and suspension stem, but for 1200 bucks vs the 4k I spent on the CC, the value is with Espin...
