This Trek Top Fuel review has it all: Speed, sustainability, shifting mindsets, and thoughts on the new breed of short travel trail bikes.
Efficient climber
Rewards punchy efforts and sit-and-spin periods equally well
Suspension remains active with good comfort and traction
Comes alive on undulating terrain
Solid chassis feel
Confidence-inspiring on descents
Handles random trail yanks well
Excellent on trails it was designed for
Higher bottom bracket and lower stack height noticeable on steep/rough terrain
Requires conscious effort to stay centered when steep and rough
Less confidence in very steep terrain compared to Spur and Tallboy

An absolute hoot to ride on all but the gnarliest tracks, a true trail bike even if on paper it doesn’t look it
Shrugs off limited travel figures on 95% of trails
Loves to twist and turn
Fast-rolling rubber helps keep speeds high
Fork can twang under heavier riders
You’re occasionally reminded of the 120mm travel

Practical detail solutions and clean look
Very wide handlebars

Trek’s Top Fuel delivers superlative short-travel suspension performance but it’s definitely a trail bike not an XC bike
Infectiously agile and playful vibe
Superlative suspension feel
Seriously tight tracking frame
Trail tough kit
Internal storage
Too heavy for XC racing
Simple fork damper
Tight internal storage access
Yawning gap between this and the Supercaliber

For a bike that is so capable on the descents, though, the Top Fuel still packs a mighty punch when it comes to gaining elevation..
Great suspension performance
Frame storage
Strong climbing performance
Knockblock isn't as well executed as other brand's versions
Works well when pushing hard, but might not be the most comfortable for all

New Trek Top Fuel 8 is a short travel - 120mm travel front and rear - down-country trail bike with internal frame storage for both alloy and carbon models.
Sublime suspension, playful handling, fantastic size range, internal storage
Not particularly light for the intended use, inconsistent Shimano brakes on our test bike
