The Specialized S-Works Shiv is one of the fastest triathlon bikes ever made — but its factory bar mount is notoriously short and limiting, leaving many athletes unable to dial in their optimal position. The KSR Shiv Riser and Adaptor solves both problems at once: it adds up to 30mm of height adjustment AND extends the reach that the factory mount simply can't provide.
Printed in-house in Australia from high-performance PPA-CF and PETG-CF, it's a direct replacement for the factory setup — no modifications required.
With the Shiv now discontinued, replacement or aftermarket solutions are increasingly hard to find. This is one of the few options available to Shiv owners who want to properly set up their position without compromising on speed.
