So I bought a used gravel bike. Its a Boardman ADV 8.6. Shimano drive and Tektro brakes. Its in great condition and when I spin the wheels they spin fast and freely and theres no noise or obvious issues.
Except when I actually try to ride the ****er its like pedalling a tank. Even in lowest gears ( its 18 speed) its very hard going even on a totally flat path.
Any ideas as to why this is?
Thanks
