Product Description

Born to win, the GT Sanction Comp 27.5” full suspension enduro mountain bike has victory in its veins, designed by a championship winning team for some serious descending prowess.

Taking inspiration from the Downhill World Championship winning Fury downhill MTB, the GT Sanction enduro bike is a thoroughbred race platform that can run with the big bikes on any descent, while still being light and efficient enough to pedal back to the top. GT’s Independent Drivetrain Suspension system works to keep any suspension movement separate from the drivetrain to all but eliminate pedal kickback, ensuring the suspension is free to do its own job unhindered.

The GT Sanction frame is made from 6069-T6 aluminium, which is more than 25% stronger than 6061-T6, allowing GT’s designers to engineer the frame to be both lighter and stronger than the competition. The COR Enduro (Centered On Rider) philosophy revolves around Fit, Function, Tune, Spec and Geometry, creating a bike that is perfectly suited to the type of rider, and the type of terrain on which the bike will be used.

Taking care of the business side of things, the GT Sanction Comp has a RockShox Yari RC boost fork attached to the front, giving a sizeable 180mm of suspension travel that will make molehills out of mountains. At the rear, the frame’s 160mm travel is kept in check by a Fox Vanilla RC coil shock, which has a linear spring rate for super supple bump sensitivity.

Giving you plenty of gears for the descents and just enough for you to pedal back to the top, a SRAM GX 1x10 speed drivetrain promises slick shifting and reliable chain retention. Speaking of descents, you’ll be thankful for the SRAM Guide R disc brakes and their sizeable 200mm rotors front and rear – they’ve got oodles of stopping power to keep you in control of your speed.

Ride up. Tear down. Repeat. The GT Sanction Comp enduro MTB is a true trail weapon.

  • 6069-T6 alloy frame with 160mm Independent Drivetrain Suspension travel, for a faster & smoother ride

Just arrived.

Brand new bike for this year for me - upgraded from a hard tail GT to this. Unreal build quality, looks amazing and the flat paint job gives it a great premium feel. I have not ridden her yet but i think im going to have a great summer on this. I would upload some pics if i could, its so imposing in person, the tyres are huge and the whole design give it a very aggressive look. Ordered over easter weekend and it arrived 2 days later, wrapped up and protected. Brilliant service and information from Lyndsey at Tredz. Thanks very much guys.

Full Sus MTB Guide

 

Is a full-suspension mountain bike right for me?

If you’re new to the world of cycling, we highly recommend taking a look at our bike buying guide overview or our mountain bike buying guide to help you decide what type of bike is right for your needs.

When you’re choosing a full suspension mountain bike, there are a few things to look out for which can help you to work out the quality and performance you can expect from a particular model.


Suspension travel & usage

Depending on the type of mountain bike riding you’ll be doing, you may want to have longer or shorter suspension travel on your bike:

Travel

Usage

Pros

Cons

Up to 120mm

XC

Lightweight & efficient pedalling for long-distance rides

Short travel is less capable on rough & demanding trails with large jumps & drops

120 – 150mm

Trail

Lightweight, balance of climb-friendly efficiency & rough-descent capability

More weight than a shorter travel bike & less efficient climbing. Less capable on descents than a longer travel bike

150-180mm

Enduro

Capable of covering difficult & technical downhill sections. Wide enough gear range for climbing

Heavier & significantly less efficient at climbing compared to shorter travel bikes

180mm +

Downhill

Designed for highly technical & high-speed descents, with big drops and large jumps

Heavy, and inefficient at climbing. Limited gear range means most climbs will require pushing the bike


Frame material

Full-suspension MTB frames are mostly made from either aluminium or carbon fibre, with each material having its own benefits & drawbacks.

Aluminium

Aluminium is lightweight, stiff, strong, and easy to manufacture. Manufacturers often develop their own aluminium alloys, such as ALUXX by Giant. Aluminium is found on a wide range of bikes, from entry-level & enthusiast bikes, right the way up to top-spec racing bikes.

Carbon

Carbon fibre is lighter, stiffer, stronger, and more expensive than aluminium. The most affordable carbon bikes typically use medium strength carbon fibres, while the most expensive bikes use stronger ‘high modulus’ carbon. Carbon fibre frames are found on enthusiast-level bikes, right up to high-performance bikes designed for racing.


Groupset & drivetrain

A bike’s groupset, or drivetrain, is where the biggest difference in component quality is seen.
A complete groupset comprises of the following parts:

  • Chainset (aka Crankset)
  • Bottom bracket
  • Brakes
  • Brake levers
  • Shifters
  • Front & rear derailleur
  • Chain
  • Cassette
MTB Groupsets

Mountain bike groupset components are typically supplied by either Shimano or SRAM, with additional manufacturers like Formula, Hope, Magura, Tektro and TRP supplying brake systems. Shimano & SRAM both produce a range of groupsets to suit different budgets. The hierarchy table here compares the different Shimano & SRAM groupsets to determine which bikes offer the best performance.


Wheel size

You’ve probably noticed that a lot of mountain bikes come in a choice of wheel size, mainly a 27.5 inch wheel (also known as a 650B wheel) or a 29inch wheel (known as a 29er). Although there are still bikes which use 26 inch wheels, these are gradually being phased out on all but the smallest bikes. The difference between these wheel sizes can have a dramatic effect on the way a bike feels and handles out on the trail.

27.5in/650b Wheels

27.5inch wheels are smaller and lighter than 29er wheels, which makes them more agile and gives the bike a more responsive & playful nature. On the other hand, the smaller wheel size rolls less efficiently than the larger size, making the bike more prone to losing speed over rough ground and making it a little slower when climbing.

29er Wheels

29er wheels have a bigger rolling radius which makes them naturally smoother over rough ground. For this reason, a 29er mountain bike often requires less suspension travel than smaller wheeled alternatives. The downsides are an increase in weight, and the larger diameter wheels generate stronger gyroscopic forces, making the bike more stable, but less agile and responsive whilst manoeuvring.

26in Wheels

26 inch wheels were once the go-to wheel size on adult mountain bikes. However, they are now typically only found on the smallest frame sizes, and on junior bikes. 26 inch wheels are lightweight and give the bike very agile handling. The downsides to 26 inch wheels are their poor rolling resistance on rough ground, and the reduced contact patch due to the smaller wheel circumference.


Suspension components

Mountain bike suspension components (i.e. the fork or rear shock absorber) are also a way to identify the quality of a bike. While Fox and RockShox are the most common manufacturers, there are a number of brands producing suspension components for mountain bikes.

Entry level full suspension mountain bikes (up to approximately £1300) may come supplied with a fork & rear shock supplied by SR Suntour, X-Fusion or RockShox. These components will allow a limited amount of adjustment, including:

  • Coil spring preload / air spring pressure adjustment
  • Lockout switch
  • Rebound damping adjustment on models towards the top of the price range.

Mid-range & enthusiast bikes (up to approximately £3500) use components from brands including Fox, RockShox and Manitou. At this level, suspension components have features like:

  • Preload adjustment / air spring pressure adjustment
  • Rebound damping adjustment
  • Lockout switch
  • Multi-position ‘mode’ switch
  • Components towards the top end of the enthusiast price range may also feature compression damping adjustment as well.

Top of the range & competition spec bikes (over £3500) also use components from Fox, RockShox & Manitou, with a few select models using parts from Ohlins. At this price, suspension components have features including:

  • Coil spring preload adjustment / air spring pressure adjustment
  • High & low speed rebound damping adjustment
  • High & low speed compression damping adjustment
  • Lockout switch
  • Multi-position 'mode' switch
  • Advanced low-friction coatings (e.g. Fox’s golden-coloured Kashima coating)
