Hi, I'm new to the forum and don't know much about cycling. I'm after some advice or opinions if anyone can help. I own a Caad9 made in USA with Shimano 105 bits, black with silver writing, I'm unsure of the year, possibly 2010, I bought it second hand a few years ago. Unfortunately I now have a child :-) so don't have time to road riding, I don't know whether to sell it or try to soften it up and put some slightly more park-friendly tyres on it for when the kid finally learns to ride. Any thoughts would be welcome!
