Bontrager Line Pro

This stem is designed specifically for handlebars with a 35mm clamp diameter. If your current bars are 31.8mm, they will not fit without a shim, which is generally not recommended for this type of high-performance component.

Blendr is Bontrager's integrated mounting system that allows you to attach lights, computers, and other accessories directly to the stem faceplate. It creates a cleaner, more streamlined cockpit by eliminating the need for bulky handlebar clamps.

Yes, the Bontrager Line Pro is fully compatible with Trek's Knock Block headset system. It also works perfectly with standard headset setups, making it a versatile choice for various mountain bike frames.

A 0-degree stem provides a neutral rise, which keeps your handlebar height consistent with the stem's mounting point. It is a popular choice for aggressive trail riders who want a balanced, responsive feel without the added rise of an angled stem.

Yes, this stem is safe to use with carbon handlebars. Just be sure to follow the manufacturer's torque specifications for your specific bars to avoid over-tightening the faceplate bolts.

The oversized 35mm clamp increases the surface area where the stem meets the handlebar. This results in a stiffer, more responsive front end, which helps with steering precision and reduces flex during aggressive riding.
