The Crankbrothers Highline XC/Gravel Dropper Post (80mm Travel, 27.2mm Diameter) offers a slightly shorter drop than the 100mm variant. This design is perfect for riders with limited exposed seatpost or gravel bike setups where a subtle height reduction helps lower the center of gravity on technical descents.

Key Technical Specifications:

• Diameter: 27.2mm for universal fitment on gravel, cyclocross, and narrow-tube cross-country frames.
• Travel (Drop): 80mm of smooth, infinitely adjustable travel.
• Total Length: 407mm from the bottom actuator to the center of the saddle rails.
• Weight: Approximately 415g (slightly lighter than the 100mm option).
• Routing: Internal stealth frame routing only.
• Internals: Premium self-contained Internal Floating Piston (IFP) hydraulic cartridge.
• Warranty: Backed by a 4-year manufacturer warranty.

Insertion & Clearance Requirements:

The shorter 80mm stroke reduces the required insertion depth, making it easier to fit into small frames or frames with tight water-bottle-boss clearance.

• Maximum Insertion Depth: 244mm is needed inside the seat tube to slam the collar flat against your frame.
• Minimum Insertion Depth: 100mm must stay inside the frame to comply with safety requirements.
• Minimum Stack Height: 60mm from the bottom of the outer collar to the saddle rails when fully dropped.

Sourcing & Lever Requirements:

• What is Included: Shipped with premium Jagwire® inner cable and housing and a tool-free quick-connect mechanism.
• Remote Requirement: No remote is included. You must pair it with a separate remote, such as the Highline Drop-Bar Remote (for drop bars) or the Highline Premium Remote (for flat handlebars).

This dropper post is a versatile and reliable choice for gravel and cross-country riders seeking smooth adjustability and compact fitment.
