I switched from a heavy mountain bike to a hybrid Fuji Crosstown 1.0 for my daily commute to work and back.
The bike was bought used and since I started riding it, it feels heavier than the old mountain bike! I feel like I am having to pedal very hard to keep it going. Actually it feels like Im constantly going uphill.
The tires arent rubbing anything, the chain is tight and lubed....
What could be wrong and how do I fix it?
