Titanium Gnarvester

All-Purpose 29+ Smile Machine

[nahr-vuh-ster] noun

1. any of various farm machines for harvesting gnar.

The Gnarvester is just a wicked fun bike. One of the earliest 29+ bikes ever made, the Gnarvester has stood the test of time and continues to bring hoots of joy to anyone riding one. Build it as a rigid singlespeed and you have a low-maintenance rig that won’t rattle your bones after a full day in the saddle. Stick a long travel fork on it and rip technical descents with the best of them. Load it for bear and take it bikepacking. Put on a drop handlebar and some shallow tread tires, and boom! You’ve got yourself a gravel bike with no limitations. The options are endless, and we are still seeing fresh fruits of your imagination almost every day.

While the Gnarvester is happiest with a 29 x 2.6 to 3″ tire, you’re welcome to run a narrower or smaller diameter tire, just mind the bottom bracket height! If you’re looking for even more flotation, check out our O’Beast or Omega’Beast frames!

Is there a little detail you don’t like? Want to tweak the geometry a bit? Have a cool idea for a frame? As with all our titanium frames, customization is no problem. For an extra $300 we can edit this frame to your liking, or start completely from scratch. Contact us any time and let us know what you’re looking for. We can help you design a frame and give you an accurate timeline for how long it will take to build.
