There are some brands of bicycles that can cost more than the down payment on a car. Why? Surely making a bike lightweight and reliable isn’t so difficult that it warrants that price? Is it just the brand name or maybe it has to do with customization options?
In around 2012 the costs of Tour the France bikes ranged somewhere around 4k to 8k (with a rumoured 12K€ bike). Source: French TV :-)
Training bikes was about half (source my lil bro^^), but as the frame were mostly carbon and glue, they were actually quite used at the end of the season.
