Great feature and perfect rise for the taller guys like me. Weight is good also and the price.
Nothing so far.
Best stem I've ever ridden, perfect geometry for the 6 ft+ rider. Rocking mine with some Vocal Local XL's with a height of 8.75 and my front end feels perfect. The long reach gives me loads of room for turndowns and inverts. All round a fantastic stem that suits all styles of riding.
