SLF SPRINT System

All SLF components are made to order. Please allow one to two weeks of lead time.

Utilizing a 14-Tooth / 14-Tooth pulley wheel combination, the SPRINT System is unmatched by any competitor on the market when it comes to strength, durability, and performance!

The new midsize SPRINT System:

Shimano Ultegra/Dura Ace 12sp is designed to only work with the 30T cassette and future smaller offerings (will NOT work with 34T cassette).  

SRAM Red/Force AXS is designed to only work with cassettes up to 30T (will NOT work with 33T and/or 36T cassettes)

All SLF Motion Systems use cages produced from "Made In The USA" 100% real carbon fiber (unlike competing brands' nylon plastic "composite" cages) along with unique coated bearings for added durability and performance.  Improve your current stock drivetrain or even your current competing Oversize System with the installation of an SLF Motion System.  Every System is designed, tested, and hand built in Pawnee, Illinois USA.
