    Abstract: A bicycle chain having an alternate succession of outer links and inner links connected to each other at respective end portions thereof. Each outer link and inner link comprises two respective plates arranged parallel to and spaced apart from one another to define a housing space for a tooth of a sprocket or toothed wheel. Each plate of each outer link has, at a central portion thereof, a first thickness. Each plate of each inner link has, at a central portion thereof, a second thickness. Each plate of each outer link and inner link has, at said respective end portions, a third thickness that is less than the sum of said first thickness and second thickness.

    Abstract: A composite bicycle rim, and a process for manufacturing the rim, having a plurality of perforated spoke-attachment seats having spaced apart first and second areas of cut structural fibers. The second area has both end portions of cut structural fibers having a longitudinal dimension greater than the first area's cut structural fibers and continuous structural fibers. At least some of the end portions of the second area's cut structural fibers are mutually juxtaposed or interposed with respect to the second area's continuous structural fibers.
