Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


With its light, layered carbon fibre frame, the Fenix SL 50 is a responsive, comfortable ride that blurs the line between race bike and endurance bike. Detour onto back roads, and the Fenix's geometry soaks up vibrations and smooths out washboard. When descending, the flattened chainstays and tire clearance (up to 28C) offer a compliant ride without sacrificing race-ready stiffness. DT Swiss E 1800 wheels are proven performers – durable, adventurous, responsive when you need extra punch, and won't weigh you down on climbs. Equipped with one of the best gruppos around, it gets a workhorse 11-speed Shimano Ultegra R8000 drivetrain that balances performance and reliability. When reviewing the Fenix SL 50 Disc in Italy, Matthew Pioro from Canadian Cycling Magazine was greeted with heavy rain and hail while descending Passo Pordoi. "The Shimano Ultegra R8020 hydraulic disc brakes allowed me to descend in that mess comfortably," he writes. The storm washed out part of the following day’s route, resulting in a longer day in the saddle than he'd expected. "At the end of our detour day, my fatigue was the result of all the pedalling, not from getting rattled by the road," he explains. "I’ve tested a few endurance bikes that feel less race-oriented and less agile in the corners. Not the Fenix."
