Guerrilla Gravity’s line of USA-made bikes are most intriguing. Recently they rebooted their line up, introducing a new modular frame platform based on a carbon front triangle that’s manufactured in Colorado. Unlike other brands that introduced new platforms recycling their front triangle mold, they’ve successfully pitched it as a desirable selling feature instead of a band aid go-around.
Using the headset cup flipchip system, one can swap out seatstay tuning kits, select components and rear shock, to effectively transform their frame into a completely different bike. It could be the most versatile quiver-killer available today.
Though we’ve spotted alloy models on the trails here and there, it wasn’t until Sea Otter that we spotted our first model in the wild: the 140mm/160mm 29″ wheeled model designated “the Smash”. Discovered at the MRP booth, it was equipped with a smattering of USA-Made componentry that included MRP suspension and Enve carbon wheels.
It was also our first time getting a close look at the unique headtube and the GeoAdjust Headset. The innovative headset cup flipchip systems allows one to adjust the reach, wheelbase and headtube angle — this frame is a bike nerd’s dream.

Swap out seatstay tuning kits, select components and rear shock to effectively be riding a completely different bike.
The model designation is listed on the seatstay; each tuning kit includes the seatstays, bearing, and derailleur hanger and bolt. This all comes with an amazing price tag for something so boutique and USA-made — a frameset price of $2195. Complete builds start at $3795.

An integrated cover provides a clean look to the externally routed cables while keeping this easily accessed.

The folks at Guerrilly Gravity like their frames long. The reach numbers mean you will want to try before you buy.

The MRP Hazzard Coil Shock is available with 3 different spring options as well as high/low speed compression adjustment and the “Shredlever”.
Guerrilla Gravity certainly has our attention – I can’t think of a bike I’d like to test ride more right now. Especially taking into account their extremely long reach measurements. For a Shred Dogg, according to their recommendations, (based on my height and riding style) they recommend a #2 Frame size in the long orientation, which features a reach of 468mm. (holy cow!)
