SKS Compit Stem phone holder With the SKS Compit, your smartphone is super firmly attached to your handlebars, even during black mountain bike tours. The holder is mounted under the existing stem cap (ahead cap). With the bar attachment (available separately), this smartphone holder is also the ideal solution for using the COMPIT system for E-mountain bikes.
