SHIMANO the difference between the various levels accessories riders often asked the difference between SHIMANO parts of each level, each verbal explanation, that is not professional, would like to get hold of writing, first in the online search, I found that did not write very detailed, and Many of the old models, or for something to do shows that can be very responsible, said a careful reading of this article, after you when choosing SHIMANO parts can definitely ease, what they had. 1: What is SHIMANO electric bike conversion kit? The main production departments SHIMANO bike bicycle speed, transmission, brakes and other accessories, we usually referred to as electric bike conversion kit, including: front derailleur (front derailleur) after derailleur, (rear derailleur), variable speed lever (mountain has taken a turn to, DIP, dual control handle these types of forms; road has changed hands (STI Dual Control lever) and DIP), the first sprocket (tooth plate), rear sprocket (flywheel), chains, hubs, brakes, and related to a variety of transmission lines & pipes, brake lines & tubes & accessories oil and so on. Two: SHIMANO each grade electric bike conversion kit ‘s Name: SHIMANO sport level mountain off-road electric bike conversion kit, from low to high name followed by: TOURNEY; ALTUS Acera ALTUS; Acera ALTUS Acera; ALIVIO; Deore; Deore LX; Deore XT; XTR; lower C050, SIS and the like civilian variable is not included, in addition to HONE (ranging between XT and LX for heavy XC and AM); SAINT (ranging between XTR and XT, for in the AM and FR); for BMX in DXR, capreo with less, but also temporarily explored. SHIMANO exercise level road with electric bike conversion kit, from low to high name followed by: 2200, SORA, TIAGRA, 105, Ultegra, DURA-ACE; lower for the civilian A050 and SIS were not in this column. Three: SHIMANO each grade electric bike conversion kit for grade orientation highway: DURA-ACE is the top competition level, Ultegra known as the professional training level, 105 is a professional entry-level, TIAGRA an amateur level, SORA is the entertainment level, 2200 be regarded as entry-level entertainment . This is a watershed in which 105, 105 (or more) can be called professional grade. Mountain: XTR is the top competition level, Deore XT is the top training class, Deore LX is the professional training level, Deore is a professional entry-level, ALIVIO is the top entertainment level, Acera and ALTUS are entertainment level, TOURNEY regarded as entry-level entertainment. Deore is a watershed, Deore (or more) can be called a professional. Above the level of points is more vague, so-called entertainment that is specific to non-travel by riding movements, fine grading again the following four: SHIMANO grades electric bike conversion kit as detailed difference now (February 2007) SHIMANO all levels electric bicycle conversion kit model for mountain: TOURNEY; ALTUS (M310); Acera (M340); ALIVIO (M410); Deore (M530 disc brakes for the M535); Deore LX (M580 disc brakes for the M585); Deore XT (M760 disc brake for the M765); XTR (M970 disc brakes for the M975); Another HONE (M600; SAINT (M800) highway electric bike conversion kit: 2200, SORA (3300), TIAGRA (4500), 105 (5600), Ultegra (6600), DURA-ACE (7800) only discuss the detailed comparison of these new models, starting from the details of each part more, read the will understand the various grades in the end worse off. ?????? Mountain: TOURNEY strictly speaking not a complete set of electric bike conversion kit, it is the entry sport to support the positioning of 6 / 7 speed Acera and ALTUS no significant difference between the price difference is small, can be simply understood as the same level, Acera main configuration 8-speed, and Acera 7-speed and ALTUS main configuration (in fact, they can be compatible with 7-speed and 8-speed), the relative TOURNEY, an increase of 8-speed support, Acera rear dial connection pin on which a sleeve fluorine coating, wear resistance, smaller and more.
