EKAR GT REAR DERAILLEUR

The Ekar GT rear derailleur has been designed using unrivalled Campagnolo experience and inventiveness, developed and perfected in over 90 years of innovation. 

The dedicated 1x system and 13 speeds make it effective, the 9-tooth sprocket allows for the birth of a complete range of gear ratios with short evenly spaced shifts and well-maintained cadence levels.

 Technology, design and material have been chosen to satisfy the specific performance needs of all-road and gravel fans, the combination of rapid precise, reliable, shifting together with high chain security, lightness, durability and strength mean it truly deserves its place in the all-road arena. 

The design of the rear derailleur with medium-length housing is compatible with the different sizes of the sprockets on all four of the cassette combination options, from 9-36 to 10-48, perfect for any gravel needs. The parallelogram’s 2D trajectory is designed specifically for the Ekar GT 1x system so that shifting entails precise mechanical movements for best use of the 13 sprockets. Its larger pulley wheels guarantee optimum working and high chain retention for security and peace of mind, whatever terrain you tackle. 

The clutch, permanently engaged for enhanced chain retention reliability and minimal operational noise, can be locked forward for easy wheel removal. There are more than 70 individual carefully designed and engineered parts in the Ekar GT rear derailleur alone. 

Carbon fiber-reinforced polyamide and anodized 7075 and 6082 alloys are skillfully combined in the Ekar GT rear derailleur’s body and cage, for the best blend of strength, durability and light weight, ensuring long-term reliable working and to withstand the knocks, sand and dust of hardcore gravel riding, while stainless steel bolts WITH SPECIAL SURFACE TREATMENT are used for strength and long-term resilience in the toughest conditions. 

EKAR GT CRANKSET

Single chainrings are obviously simple to use: no front derailleur, considerably less weight, fewer moving components that gather dirt and may cause blockages and better chain security with no useless overlapping chainrings – the perfect solution for gravel.

The two aluminum cranks are fitted with semi axles in AISI 630 steel, in line with the clever material combinations of the entire Ekar GT groupset, with a view to producing components that are always light but deliver maximum efficiency and durability.

New ProTech™ technology joins the two semi axles inside the bottom bracket, with a single sturdy screw. The oversize stainless steel bearing race is on the crank, fitted onto the semi axle for maximum smoothness and resistance – and to make it easy to access for inspection and maintenance without having to dismantle the cups.

There are five chainring options available:  36T, 38T, 40T, 42T, 44T. Their optimized design offers efficient transmission and maximum chain reliability.

The lightweight resistant chainrings in 7075 aluminum are easily interchangeable: simply unscrew them off the four arms of the crank with no need to dismantle the crankset. The four arms are arranged symmetrically for optimum load distribution and have a 104 mm bolt circle diameter. Changing the chainrings is a simple efficient way to change gear ratio while you tackle different kinds of terrain.

The Ekar GT crankset offers three crank length options – 170, 172.5 and 175 mm – to suit cyclists and bikes of all kinds. For some gravel bikes with low bottom brackets, the shorter cranks are used the most to avoid getting stuck on uneven unpredictable terrain.

A Q factor of 151 mm offers a comfortable efficient pedaling style, whatever your size.

EKAR GT 13 -SPEED SPROCKETS

The Ekar GT 13-speed cassette is available in four different options, from 9/36 to 10/48, which complete the range and reflect the different specializations on the gravel scene and each combination delivers very smooth gear ratio progression. Small jumps for the first 6 sprockets, which increase in the second half with the larger sprockets. This characteristic ensures an optimum experience on the saddle and helps you get the best from your performance on difficult routes and terrain. 

The wide selection of larger sprockets gives a more compact cassette for endurance events and longer gears for more adventurous riders. The cassette combinations are partnered with easy-to-replace dedicated chainrings to offer the widest range of gear ratios, smooth changing and maximum efficiency and, unlike the 2x systems, no waste. Two of the four combinations have a 9-tooth sprocket. In-depth comparative tests have shown that the 9-tooth sprocket is as efficient as any 10- or 11-tooth sprocket, without any additional friction thanks to its special profile tooth design, so that none of the power produced is lost.

Construction of the EKAR GT cassette retains the Campagnolo design philosophy with a single block for the larger sprockets, five individual sprockets with spacers in aluminum 7075 and an initial triple or quadruple: this construction gives the cassette optimum lightness and reactivity.  With appropriate rings and adaptors, the N3W freewheel body is compatible with all the 12-, 11- and 10-speed Campagnolo groupsets available today and in the future.
