By utilizing the fork steerer and seatpost as mounting points, the Geryon can be used on almost any bicycle. No matter what kind of riding you do, you can bring up to 30 lbs of your favorite gear for camping, fishing, hunting, trail building... the choices are endless.

BONUS: The Geryon's unique design won't hamper your steering, suspension, or dropper post functionality!


With adjustable angles and positions, the Geryon will accommodate your bike and gear like no other rack on the market. Items that were previously too bulky to bring along can now be securely attached in a variety of ways. The modular design allows you to pick and choose how you configure your rack for your needs.


With the optional Utility Deck, the Geryon can adapt to carrying larger gear like hunting tools and other long bulky items. The six point bolt system on the top and bottom of each decks allows you to attach Trxstle accessories and anything else you can imagine. The flexible system will support numerous future accessories from Trxstle!

important fit Information

Your bicycle must have a minimum of 10mm of headset spacers to install the Geryon's custom headset spacer mount.
