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'.

We used the Highsix in conjunction with a butterfly bar and found it a good option for long distance riding where adjustment on the road can be desirable. It gives a comfortable ride and, along with the range of different grips offered by the bar, allows you to alter your position easily.

3D forged from 6061 T6 aluminium using stainless steel bolts and weighing 243g (for the 110mm version), the Highsix is a fair bit heavier than most stems but it does offer strength and durability. It's available to fit two different bar diameters (25.4mm and 31.8mm) and three extensions (90, 110 and 130mm). There’s also a choice of black or silver.

The price isn’t bad for such flexibility, comparing favourably with other adjustable stems. 

Verdict

Good value for money adjustable stem. Not the lightest, but well made
