Is this stem compatible with carbon handlebars?
The ControlTech CLS stem is designed primarily for use with aluminum handlebars of 31.8mm clamp diameter. While it may fit some carbon bars, it’s essential to verify compatibility with the handlebar manufacturer to ensure safety.
Can I adjust the stem angle without tools?
The stem angle can be adjusted by flipping it to achieve a 5° rise or drop. This requires loosening and tightening the bolts with appropriate tools to ensure a secure fit.
