Many mountain bike brands offer adjustable geometry, thanks to flip-chips. But what if you want a swappable rear triangle?
The idea might sound a bit too bold, but not for Guerrilla Gravity (GG). The Colorado mountain bike specialist, known for its in-house carbon-fiber production, is now offering compatible 120mm travel rear triangles, for its entire range.
Most of GG’s bikes use a carbon-fiber front triangle, linked to an alloy rear. Last year, GG showed its first full carbon frameset, the Trail Pistol. And the rear end of this 120mm downcountry bike, is now available as a standalone purchase.
It gives GG riders on longer-travel frames, such as the Smash (145mm) or Gnarvana (160mm), the possibility of creating that N+1 mountain bike scenario. Without having to own two complete builds.
Stiffer, lighter and you can do it yourself
Mechanically, the GG Trail Pistol rear triangle is 50 percent more torsionally rigid than the Smash or Gnarvana’s alloy rear-ends. That should deliver even better climbing performance out of the saddle, and more accurate trail feedback, during high-load cornering.
There is a weight saving of 300g, compared to the Smash or Gnarvana’s alloy rear triangles.
GG supplies an axle, derailleur hanger, and cable ties with the $1,195 Trail Pistol carbon rear triangle purchase.
You don’t need any propriety tools to remove an alloy rear triangle and fit the Trail Pistol carbon upgrade to your GG Smash or Gnarvana. Just a bike stand, elementary tools and some patience.
Suppose you own one of the GG enduro bikes, and like the idea of occasionally running it as a 120mm downcountry trail shredder. The Trail Pistol rear triangle purchase could be ideal for making that N+1 dream come true without investing in a complete second bike.
