Syncros AM stem review£50.00

Affordable all-mountain option

BikeRadar score3/5

Syncros are responsible for two of the most iconic stem designs in mountain bike history – the Cattleprod and Cattlehead. The company’s output isn’t as distinctive now, but the emphasis on hard-riding performance remains.

The AM is a forged 6061 alloy stem, designed for the sorts of trails that demand a long-travel bike, although its chunky looks belie a respectable weight. Syncros’s forging process means a minimum of post-forging machining is required, although there are a couple of spots where a little more wouldn’t go amiss. Twin opposing steerer clamp bolts keep everything in line.

The AM has a slightly taller stack height than most mountain bike stem – only by 5mm or so, but if your existing stem is slammed with no spacers there might not be room. Assuming it fits, though, the Syncros AM provides a solid connection between bars and bike at an affordable price.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
