The folks at Guerrilla Gravity are pretty stoked on their US-made transformer frames. If you haven’t seen Yoann Barelli’s latest video where he swaps the rear end between long and short-travel configurations in under five minutes, it’s pretty sweet.
The Colorado brand has updated the 120mm Trail Pistol 29er model, now with a carbon fiber rear triangle that’s said to drop 300g from the previous version and is 50% stiffer. GG also switched out the bearings in the rearmost pivot for lighter IGUD bushings that they claim offer a longer service life. Thus far it’s the only model to feature the carbon seat and chain stays, but there’s a good chance the other models will follow suit.
Other updates include a derailleur cable routing that now passes through the chainstay, and better placement for the thick rubber chainslap protector.
The Trail Pistol can be built with a 120-140mm fork. Squishing a 130mm up front gives it a 65.4° head tube angle, a 74.3° seat tube angle (78.3° actual seat tube angle on size 2 frames), and all sizes have short 430mm chain stays. The bike’s reach-adjust headset means that the size 2 frame has a 458-468mm reach, giving it a full stretch of 1,190 to 1,200mm between the axles. Seat tube lengths grow quickly between the three sizes, from 400, 430, and 480mm and the reach-adjust will be a blessing for folks who want a longer frame but can’t match their inseam to that seat tube measurement.
Guerrilla Gravity made the rear center to incorporate only Plush mode, getting rid of Crush mode, and optimizing traction.
