More interestingly we found this - their new 35mm stem. With bigger wheeled bikes and evolving geometries, we think people will start to find big benefits in going shorter and shorter with their stems and for in a generation or so of bikes we'd expect to see 35mm/40mm stem replace the 50mm as the length of choice for aggressive riders. This stem puts Hope ahead of the game there and, we reckon, this is one of the best looking 35mm stems we have yet seen.
they are different stems the link is hopes dh stem, the photo is hopes new am stem. just sayin hope make loads of different lenght stems but they dont make a 50mm version of that stem i dont think
