Complete Bikes: Mega TR 275 Comp


Mega TR 275 Comp – All day adventures, for everyone


The new Mega TR 275 Comp offers the same surefooted handling and confidence-inspiring ride of the Mega AM in a lighter, shorter-travel package that’s ready for the ups as well as the downs.


Designed for trail centre fun, all-day mountain adventure racing and rollercoaster singletrack thrills, the Mega TR 275 offers 130mm of rear bounce making it the perfect option for ‘one-bike’ riders who like to tackle the gnar but want a rig they can pedal all day.


Featuring a lighter custom-hydroformed tubeset than the AM to shave off some weight; the Mega TR 275 features lightweight RockShox air suspension front and rear, full SRAM transmission, Avid braking and quality Nukeproof finishing kit.


Custom hydroformed frame with Erosion Linkage suspension


The Mega TR 275 frameset is engineered from custom hydroformed double-welded T6 6061 aluminium, with 130mm of rear travel via our Nukeproof progressive ‘Erosion’ linkage suspension action.


Oversize main bearing pivots are contained in a bespoke CNC-machined Bottom Bracket assemblyto ensure alignment, durability and precision, while the chainstay design gives clearance for a front derailleur and compatibility with all leading models of ISCG - mounted chain retention systems.

Geometry is based around an aggressive 67deg head angle and steep 73.5 deg seat angle, with a long wheelbase keeping the centre of gravity low for optimum stability at speed.


Trail bike build


We’ve gone for an aggressive trail bike build with the Nukeproof Mega TR 275 but it’s our definition of trail bike – reduced weight where possible while still up for the rough and tumble and eager to be let off the leash.


That means lightweight and adjustable air suspension – a Rockshox Monarch R shock out back and RockShox Revelation RLT Solo Air forks – but it also means big-hit burl where it counts. Those forks offer a full 150mm of rock-munching travel, with a 15mm Maxle Lite thru-axle for optimum front-end stiffness and pinpoint tracking through the rough, as well as giving the Mega TR 275 a SRAM S1000 double crankset to make the ups as easy as the downs are fun.


The rest of the transmission comes courtesy of a new SRAM X7 T2 derailleur and X5 shifters, with Avid Elixir 3 hydraulic brakes taking care of the stopping side of things.


We’ve built the Mega TR 275 Comp with a focus on downhill capability with enduro racing pedigree – because that’s the kind of riders we are – but it’s versatile enough for you to switch things up when the occasion demands.


Nukeproof Finishing Kit

Finishing kit on the Nukeproof Mega TR 275 Comp comes courtesy of our own tried and tested Warhead series of components. Our Nukeproof Generator TR wheelset sheds yet more weight from our classic DH hoops but retains the durability for the gnarl, while Maxxis High Roller 2.3” tyres are a no-brainer for a push-hard trail bike.


Our Warhead headset, stem and 760mm riser bars combined with Element lock-on grips make a fuss-free cockpit setup, while our Nukeproof Trail Mega saddle is a comfortable perch for short-blast racing or the longest of big-country days.
