Since the work was produced by higher education, the words tend to be a little bigger than we normally use. Domains may be thought of as categories. Instructional designers, trainers, and educators often refer to these three categories as KSA (Knowledge [cognitive], Skills [psychomotor], and Attitudes [affective]).
Electronic shifting is popular on time trial bikes, but generally not so popular when riding in the peloton. Some riders have had mechanical problems with electronic shifters getting stuck in one gear going up climbs. Iâve seen a few pros having to kick the small derailleur into the small ring when it has gotten stuck on the big ring, for example.
During the 2000s both Shimano and Campagnolo (2005) experimented with electronic shifting in professional cycle races. The first commercially successful electronic gear shift system for road bicycles was introduced by Shimano in 2009, the Di2.
