FSA K Force Light MTB Mega Exo Crankset

BikeRadar verdict

4 out of 5 stars

"Super-light yet stiff and strong but demands plenty of TLC "

By Guy Kesteven, What Mountain Bike

FSA’s crazy-light crankset proves that less is often more. There’s no stiffer, lighter or more race-ready mainstream option.

The high cost is partly due to the complexity of making the hollow carbon fibre arms with integrated spider. Thick, machined chainrings in either triple or double formats take the stiffness to the outer edge too.

It also rolls on £159.99 worth of ceramic bearing bottom bracket, combining super low weight with huge strength. The bearings spin silky smooth for ages if you look after them. 

It is, however, easy to crush the bearings when installing the crank arms, and cosmetic wear to the carbon is immediate. Expect a finicky setup and slower shift on the double.

    I've changed my mind abou this crank i've decided it's crap,because after 6 months of riding it as bacome unsafe,the metal that the pedals screw into as become loose resulting in pedal wobble and is seriously annoying especially riding over tree roots,so know i'm back to xtr,good reliable xtr,xtr never lets me down not like that crapy fsa, any way were was i ,oh yes i'll never buy a carbon fibre crank again!!!!!
