New TREK ROSCOE 8 Gen 4

Trek Roscoe Gen 4: What’s New and Noteworthy

Frame & Build Enhancements
• Crafted from Alpha NEXT Platinum Aluminum, the Gen 4 frame offers a lower environmental impact and is about 100 grams lighter than its predecessor.  
• Redesigned geometry includes straighter, angular tube shapes, lower standover height, shorter seat tube, and steeper effective seat tube angles—making it easier to fit a longer dropper post and offering better pedaling efficiency. 
• Compatible with 29 × 2.6″ tires, giving you ample clearance for bigger rubber. 
• Comes with a clever bolt-on frame bag made of water-resistant recycled ripstop polyester. It includes zippers on both sides and a Hypalon daisy chain for additional gear. 

Geometry & Sizing
• Maintains a 65° head tube angle, with minor tweaks to reach and stack courtesy of the increased 150 mm fork.  
• Sizes offered: Small, Medium, Medium/Large, Large, X-Large, covering riders roughly 5’1”–6’5”.   
• The Small size is spec’d with 27.5″ wheels, while all larger sizes standardize on 29″ wheels.
