Features and Construction

The LTWOO 105 jockey wheels are engineered to match the performance requirements of Shimano road groupsets, with specific attention to pulley tooth configuration and dimensional compatibility.

Material and Build

The jockey wheels utilise engineering-grade polymer composites for the pulley teeth, providing sufficient durability for consistent chain engagement across shifting operations. The construction includes precision bearings, either steel or alloy based, designed to facilitate smooth rotation under typical road cycling loads. This material selection balances weight considerations with functional requirements, ensuring the jockey wheels perform reliably within their intended application parameters.

Size and Practical Fit

These jockey wheels are manufactured in a special size configuration specifically optimised for compatibility with Shimano R7000 rear derailleurs. The 13-tooth upper pulley and 18-tooth lower pulley arrangement follows established road cycling standards, providing appropriate chain wrap angles for efficient power transfer. This sizing ensures proper alignment with existing derailleur cages and maintains correct chain tension management during gear changes across the cassette range.
