I bought this about a month ago so I could fit the Blendr accessories. Great stem - what more could I say, the Blendr system is really neat and tidied the front of my bike up
Product Details
Bontrager Pro Blendr Stem
Thanks to Bontrager's high-end aluminium construction that uses a high-quality M5 corrosion-resistant faceplate bolt, the Bontrager Pro Blendr Stem actually weighs less than many carbon stems, providing greater strength to weight ratios for a more efficient ride.
A 31.8mm clamp diameter and a 4-bolt dual band clamp securely hold your handlebar in place, ensuring that there’s no flex or loss of power when sprinting out the saddle or down on the drops. The use of Bontrager’s Blendr Pro base and Blendr XXX accessory mounts allows you to integrate your Ion and Trip lights, Garmin, GoPro and SRM accessories. Compatible with carbon handlebars and steerer tubes.
Safe installation requires a 5mm spacer above and below the stem. 5.2Nm torque wrench is required.

Reviews
Needed to reduce bar reach by couple of cm's but retain the Bontrager Blendr light/computer fitting. Does the job just fine and dandy.
