Like our original, Phlebo Buffer V2 was designed to offer a little ease to your ride. Reduces the sound of impact and as an anecdotal prospective, I've noticed a reduction in vibrations and impact in my testing. Made of TPU(thermoplastic urethane), The v2 performs like the v1 does, but is made slightly thinner to allow a better mate between the frame and soulplate. We are also including Buffer Washers to fill the void between the UFS frame hole and the UFS pegs on the soulplate for a more solid lockup. Just like it's predecessor, its universal. While designed for the core system 2, will work with other ufs frames. If you have questions on sizing, just shoot us a message and we will be happy to assist.
