Selling a Bontrager Elite mountain bike stem with a 35mm bar clamp and 35mm length. This stem is Knock Block compatible and was originally installed on my Trek Rail 5, so fitment with Trek’s steering stop system is confirmed.

The short 35mm length makes it a great option for trail, all-mountain, and enduro riding where quick steering and precise front-end control matter. Solid forged construction with proven Bontrager reliability.

Specifications

• Brand: Bontrager
• Model: Elite
• Clamp Diameter: 35mm
• Length: 35mm
• Steerer Tube: 1-1/8"
• Color: Black
• Knock Block Compatible: Yes (alignment notches visible in photos)

Trek Knock Block Compatibility

Designed to work with Trek’s Knock Block system and commonly used on bikes such as:

• Trek Rail
• Trek Fuel EX
• Trek Slash
• Trek Remedy
• Other Knock Block-equipped Trek frames with 1-1/8" steerers and 35mm handlebars

The stem can also be used on non-Trek frames with a standard 1-1/8" steerer and 35mm bar; the Knock Block feature simply won’t be utilized.

Condition

Stem is in good used condition with normal cosmetic wear from installation and trail use. No cracks, no stripped threads, and all bolts tighten properly. Mechanically solid and ready to install.

Why I'm Selling

Removed during a cockpit refresh on my Rail 5. Only selling because I changed stem length and no longer need this one.

Shipping / Pickup

Local pickup welcome. Shipping available at buyer’s expense. Stem will be packed securely for transit.

Please review all photos carefully for cosmetic condition and details. Listing is for the stem only.
