About the productCannondale F-Si HiMod 1 Hardtail Mountain Bike, In Team Replica Colours 2021

People who are after the lightest possible race weapon that will help them get that podium come race day will love the F-Si Hi-MOD 1. This 2021 model which comes in the colours of Cannondale Factory Racing is a carbon fibre cross country bike that’s all about getting up the hills, and then down those same hills, as quickly as possible.


Detailed explanation

As Cannondale, themselves say, “Light, but it’s no lightweight”. The 2021 F-Si Hi-MOD 1 is a beautiful bike that’s made to sit right next to you on the podium. With a Hi-MOD BallisTec Carbon frame and Cannondale’s flagship Lefty Ocho Carbon fork, this is a comfortable bike with plenty of traction which keeps weight to a minimum. The integrated wheel sensor gets you accurate distance and speed info and connects to the Cannondale App.

Shimano’s XTR components make an appearance with the rear derailleur and shifter in a 1x12 configuration, as well as the XTR hydraulic disk brakes and Ice-Tech rotors, with 160mm at the front and rear. The crankset is Cannondale’s HollowGram crankset with a 34T chainring, and you get a wide-range Shimano XT cassette that has you covered for both the fast descents, and steep ascents.  

The wheels are almost all-Cannondale, with HollowGram hubs using a DT Star Ratchet freehub at the rear and HollowGram 25 carbon rims that are tubeless-ready. It’s a true race-ready configuration made even better with the grippy Schwalbe tyres that are a versatile pick for the racetrack.  

The rest of the components is a combination of aluminium and carbon goods that keep weight to a minimum, while still being durable and comfortable for a day of racing.


Technical features:

  • Hi-MOD BallisTec frame and Lefty Ocho Carbon fork keep weight to a minimum while still providing maximum performance and comfort.
  • SAVE micro-suspension in the rear triangle absorbs shock for even better traction and minimized fatigue.
  • 1x12 Shimano XT/XTR drivetrain is extremely accurate and precise while keeping the weight low.
  • Cannondale wheel sensor for highly accurate speed, distance and route information without any external sensors.
Very friendly and helpful service. Daughter absolutely loves her new Frog bike.
