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.
I've got an old Schwinn Travelor that is nothing to look at but it has gotten me through 4 STP's and has been my commuter. I'm looking to get integrated shifters (currently has down tube) on the bike but I'm not sure how much it is going to cost, how difficult it will be and if it's worth it. The bike cost $70 5 years ago and I'm only willing to do this if I can get it done for around $150.
