Since then, Reynolds has made that technology their own and have improved upon it. Reynolds wheels and rims are unique in that their molding process yields one of the highest compaction ratios in the industry. This means that the rims are stronger and lighter than most of the competitions. Reynolds has perfected the the carbon clincher process which many others are still trying to figure out.
