Right!

SHIMANO kit refers to SHIMANO's bicycle division which mainly produces bicycles ^[1]

Sport grade mountain off-road kits, in order from high to low: XTR, SAINT, Deore XT, Deore SLX, Deore, ALIVIO, Acera, ALTUS, TOURNEY, lower C050, SIS and other civilian transmissions are not included In addition, there are HONE (between XT and SLX, suitable for heavy XC and AM), SAINT (between XTR and XT, suitable for AM and FR), DXR for BMX, and Capreo. Less, not for the time being.

Sports-grade road kits are named in order from high to low: DURA-ACE, Ultegra, 105, TIAGRA, SORA, 2200, and lower civilian A050 and SIS are not included in this list.

Mountain Cross Country: XTR is ** competition level, Deore XT is ** training level, Deore

SLX is a professional training level, Deore is a professional entry level, ALIVIO is a ** entertainment level, Acera and ALTUS are both entertainment levels, and TOURNEY is an entry level entertainment level. Deore is a watershed. Deore (inclusive) and above can be called professional level.

Highway: DURA-ACE is the competition level, Ultegra is called the professional training level, 105 is the professional entry level, TIAGRA is the amateur level, SORA is the entertainment level, and 2200 is the entry entertainment level. 105 of them are

As of 2008, the models of SHIMANO's various grade kits are (from low to high details):
