MODLULAR, def:"constructed with standardized units or dimensions for flexibility and variety in use." The RWC Modular Series of suspension bearing tools is the result of our effort to:
1) Reduce the number of parts required to service suspension bearings.
2) Make guides and cups more compact for use with tighter and smaller linkages.
3) Reduce overall consumer cost for high-quality made-in-USA tools
Since many different suspension cartridge bearings share common inside or outside diameters, designing this series of tools around ID and OD specific modular guides and cups greatly reduces the number of tools required to cover the wide variety of suspension bearings used in mountain bike rear suspension pivots.
