Titanium Gnarvester

A 29+ Titanium Bike Ready for Anything

[nahr-vuh-ster] noun

1. any of various farm machines for harvesting gnar.

Another platform designed by the Surly folks, 29+ combines the superior rollover of 29″ wheels with the flotation and extra suspension of a fatbike. Surly’s Krampus was the test mule that proved 29+’s impressive rollover capability, and now it’s time for the next evolution.

The Gnarvester is Carver’s take on the platform, a impressively light and nimble frame that can make full use of ~50mm rims and 29+ tires. Featuring a tapered head tube and sliding dropouts, any steerer tube or rear axle is fair game for the Gnarvester. Wrap it up with a beautiful brushed finish and a frame weight under 4 pounds, and you’re ready to get out there and harvest some gnar!

Given the lack of a front derailleur, we recommend an 11spd drivetrain in order to provide a decent gear range. Don’t worry…front chainring sizes vary from 26t to 36t so you can pick the gearing to work for yourself and your terrain.
