Looking for the benefits of an oversize pulley wheel system, but don't want to go "that big"? Please welcome SLF Motion's newest product, the Midsize Hyper Crit System. Rather than using an oversize 14/18 wheel combination like the Oversize Hyper Speed System, this new Midsize Hyper Crit System uses a 14/14 wheel combination.
To help meet the demands of close quarter racing, close curbs, and hard pressed shifting that are all a part of Criterium racing, SLF have developed a system for just these scenarios!
- Model 679 Hyper Speed Systems are compatible with cassette's up to 28T
- Model 891 Hyper Speed Systems are compatible with cassette's up to 34T
*Due to the use of stronger 7075 Aluminium (rather than 6061) and its difficulty to anodise, there may be slight colour variations on each wheel.
Shimano Oversize 14/18 Hyper Speed System: Available in both Model 679 (Ultegra 6700/6800 and Dura Ace 7900/9000 - 10 & 11sp as well) and Model 891 (Ultegra 8000 and Dura Ace 9100).
