The Taiwanese manufacturer Standwell has designed a rear carrier which needs a minimum number of bolts for mounting.
This concept has two main advantages. First the assembly time of this carrier can be minimized. Second the mounting requires fewer bolts than generally needed for an average carrier. In the bike shop this carrier can reduce stock while it is also easy for the consumer to mount.
Standwell was established in 2003 and is a specialist in the production and design of bicycle carriers. The Taiwanese company offers an array of quality carriers, kickstands and bottle cages designed with trend-setting looks plus performance.
