Signal ST / Medium

Fast and agile, Cortex is a mid-travel full suspension trail bike for big mountain epics on all terrain and flying round your local trail centre. It comes alive on long technical descents with 140mm travel up front and 135mm at the rear, big wheels and a stiff, responsive frame.
With bang up to date geometry, Cortex inspires confidence with a playful character. Stand up and mash on the pedals out of turns, manual sections of trail and pop off tree stumps, rocks and roots. Smash out short and loose technical climbs, flat-out descents and tight techy singletrack sections. The harder you push the bigger your grin.
The tried and tested Horst link design keeps the suspension active when braking. We've fine tuned the leverage curve and worked with SRAM RockShox to produce a rear shock that's custom-tuned for the Cortex - maximum downhill performance while maintaining the all-day pedalling efficiency from its predecessor. Cortex is your do-it-all bike of choice for lakeland 30-milers and flat-out trail centre laps alike; with enough travel to carry speed over longer sections of rough ground and a lively, playful feel through the twisty bits.
Cortex' frameset is hand-welded from 6061 double-butted aluminium for the perfect mix of weight, rigidity and durability; with a slim hydroformed top-tube and down-tube designed to improve stiffness with just enough compliance to get you out of trouble. Internal cable and stealth dropper routing means clean lines, dampened with foam liners for a quiet ride. Dialed-in geometry and 2.4” tyre clearance gives heaps of grip; a comfortable and efficient climbing position for big days in the saddle; and a stable, spirited platform for smashing down descents.
Why SRAM SX Eagle?
SRAM Eagle drivetrains are designed, engineered and manufactured to work as complete drivetrain systems. Its 1x drivetrain is built to be lightweight, strong and intuitive, with the gear range to ride on any terrain.
SX Eagle provides the same Eagle performance benefits as NX Eagle, but at a lower price point. The main differences stem from the choice of materials and finish options, but functionally SX is fully compatible with SRAM's Eagle groupset.

Features
2.6” tyre clearance
Bucketloads of clearance for 2.6” tyres gives you the benefits of higher volume tyres without getting clogged up in UK conditions.
Aggressive trail geometry
Neil has designed the Signal Ti to suit his aggressive riding style. A low bottom bracket makes it corner like its on rails, a spacious reach gives you room to move around on the bike, and the 66/74 head and seat angles give you the confidence to bomb the descents and while still being able to climb like a mountain goat.
Guided internal cable routing
Guided internally routed cables for a clean look and silent ride.
Titanium frame
Nothing looks quite so good as the famously resilient and durable titanium. Signal Ti’s aeronautical grade titanium tubing absorbs shock to soften the ride without any loss to feel or speed.
Custom available
We can customise any aspect of our Ti bikes. Come to us with what you want and Neil will make it happen.
Geometry and Sizing
Sizing
It is important to get the right size bike, if the bike fits it will be faster, more comfortable, and easier to handle. You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height.
