Source: bikeexchange.com (verified 2026-08-01) · corroborated by theloamwolf.com. trekbikes.com's own Top Fuel 5 Gen 4 page is JS-rendered and did not expose its spec table to automated fetching, so BikeExchange's dealer listing was used as the primary source: alloy frame, 29" wheels, a 130mm RockShox fork, Shimano Deore drivetrain, and disc brakes, at $2,899.00 MSRP (discounted to $2,299.99 at the dealer). The Loam Wolf's long-term review of the Top Fuel Gen 4 platform independently confirms the shared platform architecture — Alpha Platinum/Silver Aluminum frame, Trek's ABP suspension link, 120mm rear travel (expandable to 130mm), a 130mm-travel fork on base builds, and explicitly states "entry-level models starting at $2,899" — matching the BikeExchange price exactly. The exact 12-speed Deore cassette range and 180/180mm rotor sizing for this specific tier-5 build were additionally cross-checked against several independent retailer/spec-database listings (opticycles.com, bike-room.com) surfaced during research but not independently re-fetched as full pages, so brake rotor sizing is reported with that caveat; weight was not published for this specific alloy tier-5 build (only for the higher aluminum Top Fuel 9), so weight_lbs is left null.
