Thunderhawk | Titanium Gravel Bike

The Go-To Gravel Bike for Adventure, Exploration, and Racing

Thunderhawk is a titanium gravel bike that’s proven itself worthy across a myriad of riding – from winning ultra-distance gravel races and setting FKTs to supporting weekend bikepacking trips and cross-country expeditions. In the world of gravel cycling, Thunderhawk is the untamed podium topper that shreds anything and everything you throw in its path. Light gravel, rough gravel, rooty singletrack, sandy powerlines, muddy wetlands – Thunderhawk handles all the routes you wish to travel and in record-breaking time. Read More

A garage full of bikes is pretty cool. A garage with just a Thunderhawk is even cooler. Meet the titanium gravel bike that offers exceptional versatility, resilience, and speed. Thunderhawk is your go-to bike for gravel, snow, and anything in between.

It’s no question why Thunderhawk is recognized as Bearclaw’s flagship gravel bike. Not only is it touted for its incredible acceleration, speed, and responsiveness, but it’s also known for its vibration dampening smoothness, low weight, and low maintenance.

Described throughout the Interwebs as “fast,” “supple,” “super burly,” and “checks all the boxes,” Thunderhawk is a versatile gravel bike that’s equally as adventure-ready as it is race-ready. It comes built with Ramhorn, our high-speed, high-strength carbon gravel fork. Or, if a titanium fork is more your speed, our Titanium 100 Fork is an elegant alternative that offers greater flexibility. Both forks offer triple boss cage mounts for extra hydration or storage attachments, and they’re both rigorously tested for extreme durability and weightless dexterity. Consider it a match made in heaven.

With any Bearclaw bicycle, you have the freedom to choose a build to best suit your desired cycling endeavors. Whether you’re into gravel bike racing or exploring backcountry roads, Thunderhawk has carved its niche as the go-to bike for a range of cycling endeavors. Be it fast-paced gravel bike racing or overnight bikepacking adventures, quickly go from 700×42 race mode to a 650b wide tire setup in a matter of a wheel swap.

Experience for yourself why Thunderhawk is among the best titanium gravel bikes and one that ultimately put Bearclaw Bicycle Co. on the map. Contact us directly to inquire about purchasing a Thunderhawk frame or discuss full build options.
