BBB Highsix adjustable stem



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

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

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.

Lara has been riding bikes for longer than she'd care to admit, and writing about them nearly as long. Since 2009 she has been working as part of the review team whilst championing women's cycling on the side, most notably via two years as editor of the, sadly now defunct, UK's first and only women's cycling mag, erm, Women's Cycling. 

Believing fervently that cycling will save the world, she wishes that more people would just ride a bike and be pleasant to each other. 

She will ride anything with two wheels, occasionally likes to go fast, definitely likes to go far and is always up for a bit of exploring somewhere new and exciting.
