I have a problem with my back wheel, it feels as though it always flat and really heavy making it hardwork to get around - yes good for the training, but my legs are starting to get a little annoyed with me!!
The wheel is not flat, always pumped to 120psi, which i check most days before heading out.
The wheel is pretty true, it spins freely when i lift the wheel off the floor, however it stops pretty quickly as though it rubbing against something, but i have checked and it really doesnt look as though it touching anything.
Is this possibly an issue with the bearings?
By the way the bike is a Trek 1000 (road bike) with the original wheels, its about 2 years old, last serviced about 2 months ago.
I can change a tire and no some basic stuff about maintance, but please treat me as a practical idiot when replying as i want to ensure i understand the advice given.
