Old Man Mountain Rear Fit Kit SET821 in Black

Season:All Year Round

Brand:Old Man Mountain

Code:RAOMFK8BLK

Product Overview

Old Man Mountain's Fit Kits are designed to mount racks on bikes without traditional mounting points, making every bike capable of carrying more gear. These kits are designed, tested, and manufactured in Bend, Oregon.

Features

  • Frame Protection: Axle mounting protects the frame by moving the load from small bolts to a stud that extends from the axle and is captured by the rack dropouts.
  • Increased Load Capacity: Axle mounting increases the Divide rack’s load capacity to 33kg (70lbs).
  • Versatility: Fit Kits make it easy to swap racks between multiple bikes or between front and rear mounting with just a few bolts.

Product Details

  • Included Components: Thru-axles, pucks, and hardware.
  • Functionality: The upper puck or seat post attachment prevents the rack from rotating, ensuring minimal force is imposed on the bike frame.
  • Load Distribution: Mounting to the Fit Kit transfers the load from the frame to the axle, exerting force on the bike in the same way as the rider's weight.

Sizing Information

How to choose between Pucks and a Seatpost Mount?

  • Pucks are designed to work on any bike, and must be used if your frame has any of the following:
    • Rear suspension of any kind, including Cannondale’s Kingpin system
    • A high degree of flex built into the seat tube or seatpost (like Trek’s IsoSpeed or Specialized STR)
    • Less than an inch of exposed, unobstructed seatpost visible
  • The Seatpost Mount is an alternative to our Puck system for riders who would prefer to attach the Extenders of their racks to the seatpost, either for mechanical or aesthetic purposes.

Note: On tall frames, the Seatpost Mount may be too high for the extenders to reach without the deck of the rack getting in the way. See the examples below:

What Are Pucks?

Pucks are our super-secure universal-fit upper attachment points for bikes that don’t have rack mounting eyelets. They use frame tape and heavy duty zip ties to secure to the tubes of your frame. Pucks are designed to be safe for all frame materials including carbon fibre.

Pucks are strong, lightweight and simple solutions that may be left on the bike even when the rack is not in use.

What is a seatpost mount?

The Seatpost Mount is a collar that attaches to your seatpost and provides two eyelets for you to attach the Extenders of your rack to your bike. The Seatpost Mount is made to use with round seatposts from 27.2mm to 34.9mm in diameter. It works with all round seatposts, including carbon and dropper seatposts.
