Went for a ride today and as I was leaving the driveway, I couldn't change gears. It was like locked in 1st. After some real tugging, got it into 2nd and still had problems. But it got better over a mile and eventually worked itself out. The bike had been in the garage for a week unmoved. Butl my rides a week apart is fairly normal. A few more points: this has never happened before from a cold start but has happened a few times over the past months when on long rides. In the middle of a 3 hour ride, it would be brutal to change gears. After a while it worked fine. Last, trany oil is good and I just had my 10k service done a month ago. Has this happened to any of you? Any ideas on what's up? Should I be worried? Thanks
