True to EE’s fashion, the Top Cap and Expander are beautifully engineered pieces of intricacy. Taking relatively simple ideas and honing them into elegant and effective components takes talent and an uncompromising drive to push limits. While the execution is quite fancy the finished product is remarkably straightforward. The deeply sculpted top cap pairs perfectly with the heavily recessed expander. Maintaining a sleek contoured look while adding stiffness and making installation a breeze. The expander, with only four individual parts looks fairly rudimentary, but the genius behind it is noteworthy. The expansion rings are captive to the tightening mechanism, eliminating the possibility of misplacing or misaligning them. The integrated height/alignment skirt ensures proper installation without measuring or worrying. This simple design allows for minimal material requirements and truly makes this cap/expander combo the best available. Paired together the EE Cycleworks Top Cap and Expander are one of the lightest options on the market. The top cap and expander combined weigh in at under 10 grams.
