From the chunky rock rolls of Hydraulink Trails to the sustained tech of Okanagan Mountain Park, Kelowna's trail network demands a bike that can climb efficiently and descend with authority on the same outing. The Trek Fuel EX 8 Gen 7 is built precisely for that brief: a confident all-mountain trail bike with 145mm of rear travel and 150mm up front, an all-new Alpha NEXT Platinum aluminium frame with ABP suspension design, and a Fox performance suspension package that keeps the rear wheel glued through square-edged chop. Paired with a SRAM Eagle 70 T-Type 12-speed drivetrain and four-piston SRAM DB 8 brakes, this is a bike that rewards riders who want to push further and ride faster without stepping up to a dedicated enduro rig.

WHO IS THIS FOR? |
The Fuel EX 8 Gen 7 is built for intermediate to advanced trail riders who spend most of their time on technically demanding singletrack and want one bike that handles it all — steep climbs, punchy tech sections, and confident descents — without carrying dedicated enduro weight. Riders who regularly lap Hydraulink or explore the upper trails at Okanagan Mountain Park will appreciate the ABP suspension's pedalling efficiency and the way the Fox 36 Rhythm fork tracks rough terrain without deflecting. The modular frame platform is a genuine differentiator for riders who want to experiment with different travel and wheel configurations as their riding evolves or as seasonal conditions change. Our team at Fresh Air will help you find the right fit in-store at both Kelowna locations. Stop by to work with one of our experienced staff members, or call 250-763-3425. |

FAQ |
Q1: What size Trek Fuel EX 8 Gen 7 do I need? Trek offers the Fuel EX 8 Gen 7 in SM, MD, LG, and XL — a tighter five-size range than the previous generation (the M/L size has been eliminated, so there is a 25mm reach jump between MD at 460mm and LG at 485mm). Generally, riders in the 165–175cm range will fit MD, 175–185cm will suit LG, and 185cm+ will look at XL, but reach preference and riding style matter too. Check the Trek geometry chart linked above for full stack and reach numbers by size, then come into either Fresh Air location for a stand-over and reach check with our staff.
Q2: Is the Trek Fuel EX 8 Gen 7 right for riding Hydraulink Trails and Okanagan Mountain Park? Yes — the Fuel EX 8 is well-matched to the style of riding at Hydraulink and Okanagan Mountain Park. The ABP suspension design keeps the rear wheel active through Kelowna's rocky, rooted trail surfaces while the 64.5° head angle provides stability on steeper pitches. The 150mm FOX 36 Rhythm fork handles technical feature lines confidently, and the 30T crankset with a 10–52 cassette gives plenty of low gearing for the sustained climbs out of Hydraulink or up to the OMP ridgelines. Riders who want to push into more aggressive territory can also convert the frame to MX or LX configuration with Trek's interchangeable rocker links. Q3: How do I set up the suspension on the Fuel EX 8 Gen 7 for my weight and riding style? Trek recommends setting the FOX FLOAT X rear shock to approximately 25–30% sag as a starting point — measure sag by sitting on the bike in your full riding kit and checking how far the shock compresses. The 2-position platform lever on the FLOAT X lets you firm up the shock for fireroad climbs and open it up for descending. The FOX FLOAT 36 Rhythm fork has a GRIP damper with adjustable rebound; start with roughly 25% sag there as well. The frame also has a flip chip at the lower shock mount that shifts between a plusher (less progressive) and a more supportive (more progressive) leverage curve — riders who favour technical trail riding or plan to run a coil shock upgrade may prefer the more progressive setting. Our team at Fresh Air can walk you through all of this in person. |
