Industry Nine
The Grade 300 V2 is positioned as a tumble-ready alloy rimmed wheelset, perfect for DH bikes, bike park builds and eMTB use. A hollow bead wall design elevates the performance of alloy rim wheelsets to levels typically associated with carbon rims. This innovative shaping not only offers wider bead walls for improved impact resistance but also eliminates the concentrated pinch points found in conventional hook-shaped rims. Additionally, the triple cavity rim section enhances the structure’s strength and support, significantly reducing the severity of impact deformations. Built on I9’s Hydra 32h system hub and spoke chassis, Grade 300 V2 wheelsets offer the .52 degree engagement freehub system, combined with trademark direct-thread hubshells utilizing a one-piece machined alloy spoke creating a ride quality and customizable aesthetics unlike anything on the market.

A must for anyone doing road cycling. It’s made my ride a lot safer as it’ll warn you of incoming kook cyclists too.
This is the second time I have bought a battery for a specialized turbo e-bike. The first bike was a gen 1 and this was for my gen 2 turbo. I like two batteries as it gives me the ability to charge one while I ride using the other. Choose Sierra again for my gen 2 battery because of great service and shipping on buying my first battery from them. If you need anew or secondary battery choose Sierra
Shipping for some reason took weeks to arrive. Item arrived after I needed it so it was no use to me.
Great unit, works as expected. Sierra was quick to deliver and easy to work with. Thanks!
