To make the V1 stiff enough with the bridge around the front of the seat angle, we had to add more material to the layup which made it heavier. The new frame was done like this to achieve the desired stiffness in a lighter package. The old frame was 2.4 kg whereas the new one is 2.16 kgs (without paint) Although the Mega seat stay may look similar, they are different.

Superb balance, insanely fast singletrack shredder
A little lightweight for burlier riders

Well thought-out spec suits the intended purpose
Intuitive, balanced handling
Good suspension
Comfortable pedalling position for long rides
Climbing efficiency

Recently re-launched and now a full time member of the Nukeproof Reactor family, the Reactor 290 ST is a shorter travel version of the full suspension trail bike. With a lithe and resposive feel and top spec components, this bike – so long as you're happy to lock out the shock for climbing – makes a mean mile muncher.
