Trek Checkpoint SL Carbon – High-End Custom Gravel – XT Di2 – Size 61 Description: I am selling my exclusive and very well-maintained Trek Checkpoint SL gravel bike. The bike was assembled as a custom build at Randen Bike in Beringen (SH) in February 2019 and expertly mounted. Condition & Reason for Sale: Since the bike is part of a larger collection, it has been rarely used and is in excellent condition. The sale is now being made with a heavy heart for health reasons, as I am downsizing my fleet.
