Rockshox YARI 170mmRockshox yari

This is a truly great fork which will take everything you can throw at it. If, you were to buy the fork on its own you would be looking at around £500 – £600 pounds. Which, would still be worth the investment.

Rockshox Super Deluxe rear ShockSuper Deluxe

The Bike comes with RockShox Super Deluxe Select R, Custom ML tune, 230×62.5mm. Again if you bought the shock separately then you would be looking at around £200 – £300 depending on the model and specifications.

SX Eagle DrivetrainSX Eagle

The Mega Comp comes with the hugely successful SX Eagle 12 x 1 Drive train throughout the setup from crank to cassette. This is the budget version of the Eagle setup but it is tried and tested on many successful brands.

Dropper PostBrand X Ascend

The Modern Enduro bike would not be complete without the addition of this must have component. Nukeproof have installed the Brand X Ascend internal dropper. This dropper has proven to be a very reliable piece of kit, often out performing much more expensive posts.

Being a true Nukeproof bike, The Mega Comp also benefits from a Nukeproof finishing package. The Handlebars, Stem and Saddle are all straight from Nukeproof.


Nukeproof have gone with the SRAM Guide T brakes on this particular bike. They have also added a larger rotor with the front being 200mm and the rear being 180mm. The guide T is a 4 piston brake system with excellent stopping and modulation. If, you need to stop then these brakes will stop you in an emergency.
