SLF Motion Introduces Industry First Mountain Bike/Gravel 1X Specific Midsize & Oversize Pulley Wheel Systems


January 10, 2019; Pawnee, IL - SLF Motion, an independent cycling design and manufacturing company, is excited to release an industry first 1X specific Midsize and Oversize pulley wheel system – dubbed the “Hyper 1X System”. The Hyper 1X System was developed to reduce drivetrain friction and increase long-term durability for Mountain Bike, Cyclocross, Gravel, Adventure, and even Triathlon drivetrains. 

When building their Hyper 1X Systems, SLF Motion will be able to cater to the customer’s needs whether that be an Oversize Hyper 1X System for a SRAM Mountain Bike Eagle 12sp drivetrain, a Midsize system for a SRAM Gravel/CX Force1 11sp drivetrain, or even a Triathlon specific Oversize 1X System.


Not only does the new Hyper 1X System provide reduced drivetrain friction due to its larger pulley wheels, it is also simultaneously providing longer term durability over stock units. The “Made in the USA” aerospace grade carbon fiber cage plates, 7075 Aluminum CNC machined wheels, and coated hybrid ceramic bearings are all part of what will far outlast stock OEM units.

A critical area of interest when designing the new Hyper 1X System was its overall size compared to stock units as far as ground clearance. It is to be noted that the Midsize Hyper 1X Systems provide the same ground clearance as stock “long cage” 12/12 units. Also, to note that the SRAM Eagle specific Oversize Hyper 1X System retains the same ground clearance dimensions as the stock 12/14 cage.


Midsize Hyper 1X Systems retail for $425usd and Oversize Hyper 1X Systems retail for $485usd.
