Dual suspension Trail Carbon FAT mountain bike.

Embrace every condition, don't let even the snow keep you from a good rip on your bike! Synergy Fat gives you true, uncompromised performance in a full-suspension fatbike. This trail frame has great strength, stiffness, durability and low weight as its core. The bikes use 120mm of front suspension, while the IDS Revo rear suspension has 110mm of plush, responsive and predictable travel to attack the trails with speed and precision.

IDS Suspension system

IDS is Silverback's unique trail suspension technology. The lower linkage is concentric to the bottom bracket. This linkage uses large cartridge bearings to create a stiff and strong attachment point to the rear triangle.

Anti Squat Value

This system also uses a relatively high anti-squat value, that is optimized to complement dual and single chainring setups ensuring that power transfer remains efficient and direct. The upper linkage design creates a progressive leverage ratio that results in great small bump sensitivity as well as large impact absorption.















  1. A carbon front triangle and alloy rear triangle allows the Synergy Fat to be the lightest fat bike we have (and its a dual suspension at that!)
  2. 120mm Rockshox Bluto will soak up all the bumps the trail has to offer.
  3. The popular SUNRingle MuleFut SL80 rims are tubless ready.
  4. Quality Shimano components allows for presicion shifting in any conditions
  5. Geometry on the Synergy is trail focused, this means that the ride is comfortable for longer days on the saddle and made to cope with real world trails.
  6. Dropper post compatibility means that you can easily add an internally routed dropper post.


 synergy fat fat bike carbon frame


The Synergy frame consists of a Carbon front triangle married to an alloy rear triangle via short concentric suspension linkages. This means that the Synergy is light for a Fat full suspension, as well as being durable enough to ride every day - on any terrain. It also means that Synergy has very little flex in the frame - for a positive pedaling feel.

A durable Shimano SLX/XT 11spd wide range drivetrain offers plenty of gears to take you both up, down and all around on your Synergy, as well as making for reliable, crisp shifting in even the worst conditions.



Synergy comes as standard with a normal seatpost, but if you should want to install a dropper, compatibility means that you can easily add an internally routed dropper post. The cable enters the frame from behind the seat tube.

 silverback synergy fat fat wheel fork


A Rockshox Bluto air Suspension fork with 100mm of travel, is the perfect pairing with the IDS rear suspension on the Synergy. The Bluto also features a thru axle, for maximum stiffness - meaning more accurate steering, and the suspension works better with less torsional flex on the chassis.



Synergy Fat's geometry is designed for trail use. The rider is placed in a balanced position, that is also pedaling efficient. The head angle on the Synergy is slightly steeper than on modern trailbikes, this is to assist steering the Fat wheel, to improve handling, and to make the bike feel nimbler and more responsive.

SUNRingle Mulefut 80SL wheels are surprisingly light for big wheels, and tubeless ready making setups a breeze. These are the benchmark for fatbike wheelsets, and manufactured to deal with the varied conditions that these bikes are ridden in.
