A stem that allows you to adjust the angle of rise, the Highsix is straightforward to fit and comes at a decent price.
Getting the right angle might take some tweaking but it's a simple enough Allen key job. A higher angle suits riding comfort and offers better control whereas a lower angle gives less wind resistance. It really is a case of 'suck it and see'.
