Cyclists with Specialized Tarmac SL6 frames, listen up! This Xotic Tech adapter kit lets you upgrade to that slick SL7 stem and get that clean, aerodynamic cable routing everyone's talking about. Made from super tough POM material (that's engineering polymer to you tech geeks), this thing won't crack or break like cheaper plastic spacers. The 2.1x1.3x0.4 inch size fits perfectly and hides all those messy cables inside your headset for a pro-level look. Installation is straightforward - just replace your original headset spacers with this converter, then add your SL7 spacer on top. The improved strength means no worrying about safety hazards while you're riding hard. Perfect for anyone wanting to modernize their SL6 without buying a whole new bike. Seriously, if you've been eyeing those clean-looking SL7 setups but don't want to drop thousands on a new frame, this $30 adapter is your secret weapon. Your bike will look faster even standing still, and you'll get that premium integrated cable look without the premium price tag!
