I’m the opposite. I’ve got a carbon road bike that hasn’t been used in months, as I’m loving the MTBing too much. A big factor is who I’m riding with – I enjoy the company of my MTB mates more than my road riding buddy.
MTBing for me is about the lovely places, views and fun, whereas I associate road biking with fitness.
I do love the precision and speed of a road bike and I really enjoy riding in a pack. I might join a club as one last attempt at re-igniting my enthusiasm for it. If that doesn’t work I think I’ll sell.
