AVAILABLE IN THREE colours and 35mm or 50mm lengths, this CNC machined stem is impressively light at 122g or 137g, respectively. It uses 4mm bolts throughout and detailed internal drilling to shed any excess grams.
Unfortunately, the steerer bolts need to be done up very tight to avoid it twisting in a crash, or even when riding hard. We tested both lengths under two different testers and found the same issue each time. Cleaning and degreasing the steerer and stem didn’t help, and we wonder if the finish on the steerer clamp is simply too slippery. Burgtec don’t specify a torque setting, but tightening each bolt in alternating increments to nearly 10Nm was needed to stop the slipping. The clamp join bends visibly at this torque, which is worrying.
