# Trek Check-OUT SL 5 CheckOUT SL 5 is an adventure-ready full suspension gravel bike for getting way, way out there. Its carbon frame delivers 55mm of rear travel from a RockShox SIDluxe IsoStrut shock, while a RockShox Rudy XL fork smooths rowdy roads and trails with 60mm of travel. It comes ready to explore with Bontrager Paradigm Comp wheels, a 12-speed Shimano GRX drivetrain, and TranzX dropper post. ### Ride-it-all suspension 55mm rear travel and a new 60mm Rudy XL suspension fork designed in collaboration with RockShox help smooth out rough gravel roads and let you venture onto singletrack with more comfort and capability than a rigid gravel bike. ![](https://media.trekbikes.com/image/upload/TK25-LAUNCH-CheckOUT-TechFeatures-1.jpg) ### The ultimate off-road drop bar A new GR CheckOUT gravel drop bar has multiple hand positionings for more comfort and efficiencey wherever your ride takes you.
