Please welcome SLF Motion's new V2 Oversize Hyper Speed System. Building upon what we learned over the past 18-months using/testing/selling our Version1.0 Hyper Speed System, we have designed our new V2 system to be stronger, lighter, stiffer, to have more adjustability, and improved shifting. This new V2 system now utilizes 100% USA made carbon fiber cages, offers multiple spring tension settings, is ~15% lighter (model dependent), uses redesigned 7075 Aluminum 14-Tooth and 18-Tooth wheels for better chain engagement and easier setup, improved bearing design, and now offered in multiple anodized wheel color options.
Model 891 Hyper Speed Systems are compatible with cassette's up to 34T.
*Due to our use of stronger 7075 Aluminum (rather than 6061) and it's difficulty to anodize, there may be slight color variations on each wheel
For Shimano Ultegra 8000 and Shimano Dura Ace 9100.
