Nature BIKES
Season 2021

Getting on board the Chrono R is the equivalent of adding in that crucial extra interval to a tough session; of going flat out for 35 seconds, not the 30 it says in the plan.

Chrono R is the small extra edge that pays off big. It pairs our brilliant Xtralite Alloy 29er race frame with a lightweight, alloy stanchioned RockShox Recon Gold fork with 100mm travel. With XC Forward Geometry you’ll increase the gap every lap and the remote fork lockout adds ultimate sprint or climb efficiency. Your hard trained watts are amplified through a Truvativ Stylo chainset and SRAM GX Eagle transmission to flat out fast Maxxis Ikon tires on flow-boosting tubeless ready rims.
