Many professional cycling teams will use the Challenge Mallorca (January 29-February 1) as a pre-season warm-up, fitting in the racing around training camps.

Part of that process is assembling the rider’s new bikes for the 2015 season, and an army of mechanics work all day and often all night to get bikes ready and tweaked as the riders’ like them.

Cycling Weekly photographer Andy Jones perused the pits to bring you this gallery.
