Truvativ X0 Black 2x10 crankset£389.98

Properly light cross-country unit

BikeRadar score3.5/5

Truvativ’s X.0 crank is a properly light cross-country unit that’s also proved impressively tough since it appeared. It’s a decent price for the performance too. The broad single-kink carbon arms certainly feel stiff when you put the hammer down, and the same arms are used on the double World Champs winning downhill cranks.

The flat face also keeps its looks longer than any other carbon or black alloy set we’ve used, although the tips get tatty in rocky terrain. The X Glide double-ring shifting was a revelation when it appeared and it’s still slicker than most under pressure. The inner chainring wears quickly in winter though. Gutter seals have made a big difference to durability of GXP bottom brackets, and the BB30 versions last particularly well.

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.
