After a ride of The Oaks this weekend my steering seems to be a lot tighter than previously. When I turn the handle bar I feel a lot more resistance than I used to. It still turns the usual ratio, and seems to turn without any click and stops. I also have less control when I get up to speed as it is harder to turn due to the extra resistance.

Any ideas or suggestions on what may cause this? And how to fix it?

Thanks in advance!!
