Trek vs. Specialized mountain bikes – How do they compare to one another?
Apart from their hardtail features, both bikes have impressive suspension forks which also feature some differences.
Trek Roscoe 8 has 120mm RockShox’s Solo Air forks which are light in weight and automatically adapt to the rider’s weight. The suspension forks also come with a Turnkey Hydraulic lockout which absorbs any hard hits you may encounter as you ride.
Specialized Fuse Comp 6Fattie features 120mm SR suspension forks and a compression lockout, designed to deliver a bump soaking performance as you tame the trail. With this longer travel suspension fork and its high volume tires, the Comp offers the rider a smooth ride with more traction.
Trek Roscoe 8 has a sleek design and sturdy construction due to its Alpha Gold Aluminum frame. The frame also features a tapered top tube, dropper post routing as well as internal derailleur to help you convert more of your power to speed. With a G2 geometry frame, this mountain bike provides low-speed maneuverability as well as high-speed stability.
Specialized Fuse Comp 6Fattie consists of M4 Premium Aluminum frame which provides a smooth and lovely ride. The stiff frame also has elegantly formed seat and head tube, 148mm thru-axle dropout and 430 mm chainstays for optimum stability when riding at top speed.
Trek Roscoe 8 has wide 27.5*2.8 tires with Schwalbe Rocket Ron Performance for outstanding corner control stability as well as exceptional rolling speed. Ideal for choppy terrain, these chunky tires offer additional suspension while covering up the notchy action of the forks.
On the other hand, the Fuse Comp consists of 27.5*3.0 tires for excellent speed on both rough and smooth terrains. These high volume tires easily conform to the ground, thus giving the rider extra ‘float’ and more grip for a more enjoyable ride. It also has WTB Scraper i45 rims that provide excellent support to the tire.

Frequently Asked Questions
What is ‘full suspension’ in a mountain bike?
Full suspension means a bike has both front and rear suspension forks. When riding in rough terrain, suspension forks absorb any shocks you may encounter allowing for a smooth ride.
What is a ‘hardtail’ bike?
Hardtail bikes are mountain bikes with front suspension forks but do not feature shock absorbers in the rear. They are lightweight, fast and offer effective climbing traction.
How do disc brakes benefit me when riding?
Disc brakes are essential for bikers who ride in wet terrain. With standard rim brakes, riding in mud results in covering the entire braking surface with mud, which may damage your bike as it is a combination of lubricant and abrasive.
Is a men’s bike different from a woman’s bike?
The only difference between a men’s bike and a woman’s bike is the top tube length. Women’s bikes feature a shorter top tube length for more grip and control as well as a more comfortable ride.
What other gadgets do I require when riding?
Other accessories you may need when riding on a trail are gloves to absorb trail vibrations and prevent hand/wrist numbness; a helmet, repair tools and a first aid kit in case of an accident, water, and chain lube; among many others.
