Big Time Adventures Ahead

Why We Love It
The All-City Gorilla Monsoon is tough, confident, and ready to tackle rowdy roads many drop-bar bikes wouldn't dare go down. True to what All-City is known for, the frame is built with trusty Steel 612 Select Tubing that provides a beautiful chatter damping ride. As with all the best adventures, the longer the better. So, the Gorilla Monsoon is capable of mounting hefty front and rear racks for panniers, trunk bags, or extra bottles. It also has ample space inside the main triangle for pretty substantial frame bags making this steed a very capable and worry free bike-packing rig. Big time tire clearance and versatile wheel size options allow you select your favorite setup of choice depending on what the next adventure demands.
  • Santa Cruz Reserve 25 carbon wheels are lightweight & durable.
  • New shifter cable & housing, pro-tuned to optimize crisp shifting.
  • Curious about one of the biggest perks of buying with TPC? Read about our Guaranteed Buyback Program. It comes standard with every bike we sell.
  • We've found All-City bikes run a little big and recommend studying the geometry numbers included on this page or reaching out to our knowledgeable Ride Guides to help make sure you find your correct size.
Master Mechanic’s Notes
  • Small scratches on the non-drive side of the top tube, fork, & chainstay.
