A year is a long time, lets say you rode.....4 hours every week. Thats
4x52=208 hours riding.
lets take....30 hours off that for missed days etc.
178 hours is a long time being put under extreme pressures of trials, and judging from your riding gallery, you aint' so bad. In conclusion, split the parts and sell the bike that way, you will make a bit more this way, particularly as people aren't really after full bikes in the price range you are talking about selling it at.
