Campagnolo EKAR GT Gravel Crankset (Black) (1 x 13 Speed) (Ultra-Torque) (170mm) (36T)

Campagnolo EKAR GT Gravel Crankset Description:

The Campagnolo EKAR GT Gravel Crankset is a 1×13-speed crankset that has been designed to maximize the performance of bicycle equipped with Campagnolo’s EKAR GT groupset. Aluminum crankarms are stiff and shrug off impacts from rocks and other trail obstacles, and are connected together using robust 25mm diameter AISI 630 steel Ultra-Torque semi-axles bonded to each crank arm, which are connected in the middle via a Hirth ProTech™ joint and a substantial steel bolt that not only has proven to be a stout system, this construction technique makes it much easier to inspect and maintain the stainless steel bearings/races. 7075 series aluminum alloy chainrings are optimized for use with a 13 speed EKAR/EKAR GT cassette and chain, and are bolted to the crankarms via a 4-bolt symmetrical 104BCD bolt pattern for excellent performance and an easier time sourcing replacement chainrings. The Q-Factor (distance from the center of the bike to the crankarm) makes it easier for a rider to get into a comfortable pedaling motion and provide clearance so these cranksets can be fitted onto a wide range of bike frame configurations, while the chainline offset of the chainrings results in excellent chain retention and shifting performance throughout the entire 13-speed cassette gear range. Plus, four different chainring sizes and three different crank arm lengths are available to dial in the bicycles gearing and the fitment of the crankset to many different leg lengths/proportions. Add all of these features together, and the result is a crankset that will provide plenty of ruggedness, bike and rider fitment, gearing flexibility, and a reasonable weight that makes them an easy addition to any gravel or adventure bicycle fitted with a 1×13-speed Campagnolo EKAR GT groupset.

Notes: Bottom bracket cups are not included with the crankset. Also, Campagnolo states that the minimum chainstay length (measured from center of bottom bracket spindle to center of rear hub axle) for these cranks is 410mm (approximately 16.14″); shorter chainstays on the frame will negatively affect chainline, shifting performance, and chain retention, as well as increasing the likelihood of the crankarms, chainring, and the riders foot coming into contact with the frame.

Features:

• Aluminum crank arms with 25mm diameter AISI 630 steel Ultra-Torque semi-axles bonded to each crank arm, and a Hirth ProTech™ joint in the middle that is held together with a large bolt provides a robust and stiff set of crankarms while keeping the overall system weight in check
• Oversized stainless steel bearing race fitted onto each semi-axle to allow maintenance without having to remove the bottom bracket cups (sold separately)
• 4-bolt chainrings with 104mm symmetrical BCD are made out of 7075 series aluminum alloy and feature an optimized tooth profile for positive engagement with the chain to reduce the chances of a chain dropping off, especially when aggressively shifting over challenging terrain
• Chainrings are easily replaceable without having to remove the crankarm from the bike; simply un-bolt, slide the old chainring over and off the crankarm, slide new chainring into place, and bolt it on
• 151mm Q-Factor provides room to clear wider rear triangles typically found on gravel bikes, while maintaining a narrow enough profile to promote an efficient and natural pedaling stroke/style
• 47.5mm chainline is optimized for 135mm to 142mm rear hub spacing (typical of gravel bikes) resulting in better chain retention, smoother shifting, and a longer useful chain life
• 4 different chainring sizes (from 36t-42t) and 3 different crankarm lengths (170mm, 172.5mm, and 175mm) are available to make it easier to dial in the fit and gearing of a bike
