LTWOO 105 Rear Derailleur Jockey Pulley Replacement Kit for Shimano R7000 Compatibility
Features and Construction
Material and Build
While the specific materials for the pulley wheels and bearings are not detailed, such components are typically constructed from engineered composites, aluminium alloys, or steel, with sealed bearing cartridges. The 'colourful version' suggests a coated or anodised finish on certain parts, while the 'economic edition' likely utilises a standard finish. The product's designation as 'LTWOO 105' indicates it is part of a specific component series from the manufacturer.Size and Practical Fit
The product is listed with a 'special size' specification. This term confirms that the component is not a universal fit but is engineered to the exact dimensional requirements of the Shimano R7000 rear derailleur. The key functional specification is the tooth count: a 13-tooth upper pulley and an 18-tooth lower pulley. This large pulley design is a recognised upgrade path for some derailleurs, intended to improve chain wrap and shifting precision, particularly under tension from the rear cassette.Uses and Placement
Event or Professional Use
Everyday Home Use For the home bicycle mechanic or enthusiast, this kit enables a targeted repair or upgrade project. It is suitable for cyclists who perform their own maintenance and wish to refresh a derailleur that has worn jockey wheels, characterised by noticeable play, noise, or degraded shifting. The availability of an 'economic edition' provides a budget-conscious option for straightforward functional replacement, while the 'colourful version' caters to those also considering aesthetic customization of their bike's components.Benefits and Buying Value
Reuse and Low Maintenance
Why Choose This Product This LTWOO kit is a logical choice due to its confirmed compatibility with a widely used groupset, the Shimano R7000. The clear specification of upper and lower tooth counts (13T/18T) and the option between colourful and economic editions allows for an informed purchase based on performance intent and budget. It solves the specific problem of sourcing a correctly sized, functional replacement part for a precise derailleur model, saving time searching for compatible components.
