Geometry & Ride Characteristics

CAD of 56 Salsa Cutthroat C GRX 810 (Use BikeInsights.com to compare/contrast bicycle geometries)

The Salsa Cutthroat C GRX 810 geometry is made for the challenges of ultra-endurance bikepacking races, particularly the Tour Divide. Its drop-bar mountain bike geometry is characterized by a longer effective top tube, which allows riders to stretch out and maintain an aerodynamic position, crucial for battling headwinds. The bike also features a slack headtube angle, ensuring stability on steep and unpredictable descents, while its shorter chainstays provide nimbleness and quick handling. The combination of these geometric features, along with the Class 5™ VRS, ensures a bike that’s both aggressive and comfortable, designed to handle the rigors of extended off-road expeditions.

Riding the Salsa Cutthroat C GRX 810 feels like a seamless fusion of speed and resilience. Its geometry, coupled with the Class 5™ VRS, delivers a ride that is both responsive and forgiving, making it adept at handling rugged trails, gravel roads, and mountain passes. The bike’s design leans towards endurance-oriented bikes, and with its drop-bar, riders can anticipate a forward-leaning yet comfortable riding position. This setup not only offers better aerodynamics but also ensures reduced fatigue on the rider’s body, making extended backcountry trips and competitive races more enjoyable and efficient.

Salsa Cutthroat C GRX 810 Featured in the Wild

The New Salsa Cutthroat Carbon GRX 810 1x is Built for High-Speed Adventures

The Salsa Cutthroat C GRX 810 is an ultra-endurance mountain bike designed for high-speed adventures. Inspired by the Tour Divide, a challenging bikepacking race from Canada to Mexico, the Cutthroat is engineered to be swift while carrying significant gear. The 2020 redesign has made the bike lighter and more compliant, enhancing its cargo-carrying capacity. Selene Yeager, the author, notes, “Fully loaded, the ‘Cutty’ is graceful, quick, and eye-catching, more pack unicorn than mule.” The bike’s geometry, combined with over 20 frame mounts, ensures a blend of speed and utility, making it a top choice for gravel-enduro racing and aggressive gravel riding.

2021 Salsa Cutthroat Carbon GRX 810 Review

The Salsa Cutthroat C GRX 810 is not your typical gravel bike. As reviewed by Matthew Page on off-road.cc, this bike is a unique blend of mountain and gravel biking, specifically crafted to handle the challenging ultra-adventure race, the Tour Divide. However, its capabilities extend beyond this niche. Page describes the Cutthroat as “incredibly capable and a huge amount of fun to ride,” even questioning if a hardtail mountain bike might be a better choice for some. He further states, “The Salsa Cutthroat might have been designed to tackle the Tour Divide, but I found myself choosing to ride it over more ‘standard’ bikes available simply because of how enjoyable it was.” The bike’s geometry, combined with its wide tires, offers a ride that’s both efficient and thrilling, especially on rough terrains.

Specs

Frame Construction

The Salsa Cutthroat C GRX 810 frame is designed to accommodate a 29 x 2.25″ tire size, with the capability to fit up to a 29 x 2.4″ tire. The frame is versatile, designed to work with both suspension and rigid forks, featuring lengths of 506 mm (with 100 mm of travel) and 483 mm, respectively. For added stability and precision, the bike employs a 110 x 15 mm thru-axle in the front and a 148 x 12 mm thru-axle in the rear. Unlike traditional welding, the frame’s construction utilizes interior molds at all main front triangle junctions during the layup and curing process. This technique allows for precise control over wall thickness and inner-wall smoothness, particularly in high-stress zones. The result is increased compaction, reduced voids and wrinkles, and a top-quality carbon frame that consistently delivers high performance.

Got my dream bike packing bike

It was amazing! There were some small scratches on the front fork, which they were super quick to respond about and give me a partial discount on the bike on top of the discount they already had going for the holidays on my new Cutthroat. The bike has been a dream and I can’t wait to take it out on all my local trails here in Utah. Thank you campfire cycles!
