The KILO frame made by Tifosi works well for Cylcling and running. The wrap around style of the frame is made from a very light, non metallic material called Grilamid TR-90.
You can purchase this frame with the optional prescription insert or without.
We have also added the option to purchase the frame with the insert empty if you wish to have the prescription part made up by your own optician.
