摘要

The arrangement includes a clamping ring having a lower internal part threaded to the steering fork stem and an upper internal part surrounding the handlebar stem. A lock nut surrounds the external upper part of the clamping ring and is operable to force it into engagement with the handlebar stem to lock the steering fork stem to the handlebar stem. For connecting the clamping ring to the fork stem, a slot extends axially through the interior part of the clamping ring and an axially extending slot is formed in the outer wall of the fork stem. A washer beneath and adjacent the lower surface of the clamping ring has spaced slots in its inner edge. A pin extends through and into the slot in the clamping ring and one of the axially aligned slots in the inner edge of the washer.
