The 29/27plus platform has another option, this time in the form of a aluminum frame made in Colorado. Guerrilla Gravity looks to take a slice of the shorter-travel market with this 120 mm travel frame, the Trail Pistol.
Eagle-eyed readers will notice the change to a Horst link/chainstay pivot. Why? Guerilla Gravity says: “Marketing, mostly. Before we committed to switching to the more popular platform, we made sure the same go-fast qualities as our single pivot Megatrail layout were maintained: excellent pedaling characteristics and mid-stroke support. As an added bonus, we were able to reduce braking influence by eight percent.”
The flip chip in the suspension linkage adjusts both the suspension leverage. The Plush mode works well with the more plush 27plus tires, and the Crush mode goes well with the 29er wheels. As a final note, pay attention to sizing on these bikes; most riders will size down. This is the only brand I would go for a medium frame at 6 feet tall.
Frame Highlights (via Guerrilla Gravity):
- GG-style geometry: 120 mm travel, 16.9” chainstays, roomy cockpit. 66.6º head tube angle with a 130 mm travel fork (+/- .4º per 10 mm of travel)
- Crush Mode: made for goin’ fast on 29-inch wheels
- Plush Mode: maintains a consistent BB height between wheel sizes, steepens the head angle a degree, and reduces the progression in the suspension. Ideal for 27Plus wheels, but can be used as a less-aggressive mode with 29-inch wheels
- No fork swap necessary to use either wheel size
- Tire clearance: 29×2.6; 27.5×3.0 (both are actual measurements, not claimed since all tire manufacturers seem to use a different ruler)
- Low standover for improved agility, especially on smaller frame sizes
- The steeper angle is intended to maintain consistent geo as the saddle is raised and lowered
- “Follow the Leader” standards: Boost 148 rear end and 210×50 metric shock sizing
- Universal Syntace derailleur hanger and axle system and easily-accessed Enduro Maxx bearings
- Frame storage: NUTS (Necessities Under the Saddle) Bracket and water bottle mounts
What’s it going to cost? Prices will range from $2,200 for a frame with a Deluxe RT3 shock or SRAM GX build for $3,000, up to a SRAM XO1 build for $5,500. See all the builds at Guerrilla Gravity.
